B)Construction measurement technology design content
First of all, we should check the original big place and the intact degree of the measurement sign when we set foot on the survey.
(A) based on:
1. "Urban Engineering Pipeline Comprehensive Planning Specification" (GB 50289 - 98)
2. "Engineering Measurement of the basic terminology standard" (GB/T 50228 - 96)
3. 50026 - 93)
(2) according to the problems in the measurement area to put forward the general principle of dealing with the problem
1. Supporting pipeline project is an underground building, laying in the urban areas of dense buildings, in a narrow section of the arrangement of a variety of pipelines, often up and down, crisscrossing. Therefore, in the pipeline project measurement, the surveyor is required to strictly in accordance with the design position on the drawings, the correct pipeline measured on the ground. To this end, must use the city's unified coordinates and elevation system, in accordance with the "whole to local, first control after the broken part" and "step by step with the check" principle.
2. This project construction construction goal is "excellent", must be high quality, high standards, strict requirements for engineering construction, measurement tasks must be accurate, fast, high-quality construction of the project to provide reliable and accurate data.
3. Construction measurement, a process of measurement error exceeds the limit, must be analyzed, re-measurement.
4. According to the specification requirements, the construction of the project to take measures as follows:
(1) the error in the location of the wire network points shall not be greater than 5 centimeters.
(2) four equal triangular network measurement angle error shall not be greater than ± 2.5 "".
(3) The level measurement adopts the method of fourth-class level measurement, and the inaccuracy of level measurement closure is ±12√L (L is the length of the line).
(4) A construction control point is set every 150 meters or so.
C) construction measurement (according to the progress of construction, measurement work to do a good job with the work)
A) construction preparation and the establishment of the construction control network
1. Instrumentation of professional testing, detection of some of the systematic errors of the instrument itself, and make a good record.
2. The design unit provided by the control points, leveling points one by one to check the number, level, pile type, orientation, firmness, reliability of a thorough investigation, to be approved after the error, and then testing, tethered stakes, marking, and tethered stakes measurement results into the drawing of the point of record.
3. Establishment of plane, elevation of the professional construction control network
Surveying work must follow the "from the whole to the local, the first control after the broken part" principle. First of all in the construction area selected points with control significance, naming. Considering the characteristics of the construction site work and the need for frequent sampling, construction control points should be drawn on the construction plan, tethered stakes, do point map. Then use concrete stake markers to fix them as the basis for construction sampling and other measurement work. Then control measurement, accurate determination of the position of the established control points, and then control measurement as the basis for the fragmentation of the measurement and measurement work.
Control measurement consists of two parts: plane control measurement and elevation control measurement. According to the characteristics of the project and the requirements of construction measurement, the plane control network using wire network as the basic control. The guide line measurement system determines the length of each side and the turning angle to gradually establish the control points, and then according to the coordinates of the starting point and the starting azimuth can be calculated from the coordinates of each control point. In the establishment of elevation control network, according to the characteristics of the project site and save money on the point of view, the plane and elevation control network of two control points into one for use, reduce the cost of concrete piles even if it is to improve the accuracy of measurement and convenient construction sampling.
Two pipeline centerline measurement and well sampling
Before the start of the line, according to the drawings provide the basis for the line, the centerline of the pipeline centerline and check well location. Each check well in addition to nailing stakes, but also set up a hitching point stakes, and in the hitching point on the hitching point to indicate the hitching pile number, hitching pile material, check well number, distance, direction, with the point of the mark to do a good job of record-keeping work.
The task of centerline survey is to measure the position of the designed pipeline in the river channel and mark it with wooden stakes, which includes the measurement of the main point (i.e., the starting point, the end point and the turning point of the pipeline) and the burying of the mileage stakes, etc. The survey will be carried out in the middle of the river channel.
1. Main point measurement
First, according to the design coordinates of the main point of the pipeline, calculate the relationship between these points and the nearby control points, and then use the method of measurement and positioning, through the coordinates of the inverse calculation of the measurement data, the main point will be calibrated on the ground.
2. Setting mileposts and adding piles
In order to determine the length of the pipeline and map the longitudinal and transverse sections, a milepost is set along the centerline of the pipeline from the starting point at regular intervals (generally 20 meters, 30 meters or 50 meters), and piles should be nailed at the important features between the adjacent mileposts and at the changes in the ground gradient.
When making centerline measurements, distances should be measured back and forth with a steel ruler in order to avoid errors.
3. Pipeline longitudinal and transverse cross-section measurement
(1) leveling points
Longitudinal leveling should be set up along the pipeline before a sufficient number of leveling points, leveling, longitudinal leveling and pipeline construction of the segment attached to the construction of the citation of the basis of the elevation.
In the center line of the piles, measured perpendicular to the center line in the direction of the distance from the center line and the elevation of each feature point, according to these data to draw a cross-section map, is the cross-section map. It is the basis for calculating the amount of earthwork and determining the boundary of trenching during construction.
Three) pipeline construction measurement
1. Before trenching, first in the check well wells buried in a sample plate (with a straight support plate can be, the length of the slot width plus 2 meters), and will be the center line and the mouth line moved to the sample plate. Such as mechanical trenching, you can first use white ash to spread a good side line, to be dug after the trench earth, should still be supplemented with a sample plate to ensure that the center line of the pipe position is accurate. According to the measured ground elevation to calculate the depth of the trench, the width of the upper mouth, and use wooden stakes or white ash to put out the pipeline and check the edge of the trenching well line.
2. Pipeline construction survey is the main task according to the project progress requirements, for the construction of measuring and setting up a variety of signs, so that the construction personnel can easily grasp the direction of the center line at any time and the location of the elevation.
After the pipeline center line is set out, according to the center line position and the width of the pipeline excavation, in the river after dredging the bottom of the trench ground scattered gray line shows the excavation boundary. In the trench digging pipeline slot, the center line of each stake will be dug out, therefore, when the trench excavation to a certain depth, the pipeline must be re-examination of the center line position. First of all, the center line of each turning point measured in the trench calibration, the latitude and longitude instrument placed in the pipeline starting point, aiming at the other end of the pipeline point of the stake on the sign, the direction of the line of sight that is the direction of the pipeline center line, according to the direction of the stake calibration in the trench.
In order to indicate the depth of the trench excavation, but also in the stake mark to make the elevation mark. According to the nearby control level, determine the top surface elevation of each stake.
Pipeline construction measurement in the detailed coordinates and detailed elevation measurement:
Detail coordinates: start, end, turn, intersection (all measured pipe centerline or trench center) and the center of the pipeline line of the large well wells,
Detail elevation: the ground, the well platform, the top of the upper water pipe, the bottom of the lower water pipe.
(2) Elevation measurement
First in the pit, set a temporary level point, the level meter is placed in the pit, the back view of the temporary level point, the front view of the pipe to be measured at the point of the ruler (the use of a smaller than the diameter of the pipe of the homemade ruler), you can get to the point to be measured elevation. The measured elevation and the bottom of the tube design elevation comparison, the difference is more than ± 1 cm when you need to correct.
In order to ensure the quality of construction, every 0.5 meters of jacking should be carried out once the center line measurement and elevation measurement, deviation in the allowable range, before continuing jacking.
(B) drainage
Because of the tight schedule, so the form of open ditch, set up a water pit in the downstream to ensure that the construction surface is dry, ditch depth of 800mm, 500mm wide, i=1%; artificial catchment wells pumping, catchment wells set up every 15 meters to 20 meters, wells dug and dry brick, the periphery of the grass bag wrapped, or the seat of the well plate sinking method of water pumping. In the case of serious sand flow, play a large well beforehand, one for every 20 to 25m, and then dig the soil after stabilizing the pump and lowering the water in advance. Appropriate increase at the working well and water collection well.
Specialized personnel are responsible for monitoring the water level of all collection wells, and special people watch the pumps, strictly control the groundwater level under the construction work surface, and ensure that the groundwater level is 0.5m below the work surface.
(C) Foundation
The excavator is used to excavate and load the soil for transportation. Clear the bottom by hand according to the horizontal pile, and strictly prevent over-excavation or disturbance of the foundation. Found soft or over-depth (silt ≥ 0.5 meters, foundation treatment and design **** fixed) should find design, supervision agreed to backfill with stone chips, according to the design requirements of the compaction coefficient of compaction treatment.
