Top pipe through the main safety precautions focus on: the construction process of roadway settlement, collapse accidents, underground pipeline damage, electrocution accidents, falls, lifting injuries, traffic accidents, etc.
Second, the technical measures
(1) to prevent roadway settlement, collapse
①do a good job of construction preparations for the construction of the top pipe before the construction of the construction, to the construction personnel of construction technology, safety and technical briefing from the ideological first to establish the quality and safety awareness;
Selecting quality pipe materials, the arrival of quality pipes, the safety and technical briefing. Construction personnel for construction technology, safety technology briefing, from the ideological first to establish quality and safety awareness;
② selection of high-quality pipe, the arrival of materials to do a good job on-site inspection and acceptance of unqualified products resolutely to be returned;
③ do a good job of supplying materials, the beginning of the top of the material before the start of the plan, and in the field ready to prepare a sufficient amount of surplus, in the top of the pipe before the start of the work, ensure that Before the pipe jacking work starts, make sure all the pipes arrive at the site;
④Prepare well before the pipe jacking work;
⑤In the process of pipe jacking construction, lubrication and wear reduction should be done well, and the pressure and lubrication should be adjusted in time according to the factors such as the ground change and the water table condition, etc., and the amount of the soil output should be recorded every day as the basis for analyzing the loss of the strata, and the record will be responsible by the person in charge of it, and the record will be inspected every day at regular intervals;
⑥ In the process of pipe jacking construction, the operation safety of the highway should be ensured at the same time, and a special person should be responsible for detecting the traveling condition of the road and whether the road surface is settling or not.
7 In the jacking pipe through the road surface set up spacing of 2M observation points, according to the jacking position of hourly measurements, found that the settlement of more than 3CM should immediately stop the operation, to find out the reasons and take corresponding measures before continuing the construction.
8 pipe jacking process, do diligently measured and adjusted, axis and elevation control within 5CM, to ensure the smooth progress of the steel pipe.
(2) prevent the pipeline from breaking underneath
①before the pipe jacking construction, led by our unit, contact with the relevant departments to confirm whether there is a pipeline passing within the scope of pipe jacking construction;
②after confirming, adjust the route and elevation of pipe jacking construction in time in order to avoid intersection of the pipelines;
③if abnormalities are found in the process of pipe jacking, contact with relevant departments in time. Contact.
(3) Prevention of traffic accidents
①In the construction of this pipe jacking, except for the highway, the rest are farmland and factories, so the prevention of traffic accidents is mainly to prevent the occurrence of traffic accidents due to the pipe jacking operation of the road closure and the positive bypass highway traffic accidents;
② before the pipe jacking operation, by the person in charge of the highway road administration to contact, and the implementation of the traffic signage;
③ to avoid the road load, such as the road surface load, if the pipe is found to be abnormal, contact with the relevant departments in a timely manner. Avoid roadway loading, such as in the jacking pipe across the roadway traffic accidents or vehicle breakdowns, timely towing away the accident or breakdown vehicle.
Three, emergency resources analysis
