Matters needing attention in earthwork contract: 1. During construction, (1) the distribution of surrounding underground facilities and pipelines must be ascertained in advance and recorded; If a new pipeline is found during digging, it shall be reported in time; (2) When the depth exceeds, anti-falling measures and warning signs shall be set at the limb, and personnel shall be provided; Signal lights shall be set during night construction; (3) Control the excavation slope of the trough section, and the special supporting operation shall conform to the design scheme to ensure the supporting effect; (4) Effective drainage measures shall be set during the construction of foundation pit and roadway, and dewatering outside the pit shall be adopted for deep foundation pit to prevent water accumulation; (5) After rain, the soil and supporting conditions of the slope shall be checked first, and the slope shall be reinforced when necessary; (6) Clean up the periphery of the excavated pit, leaving enough redundancy to prevent the earth and rock from falling back and hurting people; Manual cleaning shall be carried out in accordance with relevant regulations. 2. Blasting operation (1) Before blasting operation, clear signs must be set up, warning areas should be demarcated, and special personnel should be arranged for inspection to prevent pedestrians from passing; (2) Smoking and kindling are strictly prohibited within the operation scope; (3) Ensure that blasting operators hold relevant certificates and operate according to the regulations; (4) The blasting operation process must be confirmed for the second time, and the safety zone shall be set according to regulations; (5) Strengthen the inspection of drilling and charging to ensure the correct position and reasonable dosage; (6) Determine the blasting network and initiation sequence, and conduct simulated explosion test first. 3. Mechanical equipment (1) It is forbidden for heavy vehicles to pass and park within 1m of the pit; (2) Fixed measures shall be taken for suspended equipment parts to prevent falling from high altitude; (3) Earthwork construction shall be at least 2m away from high-voltage lines; (4) The vehicles entering the site can only be used after passing the inspection, and they shall be maintained regularly; (5) Set up construction signs and protective facilities, and regularly check and reinforce them by special personnel. 4, construction electricity (1) The power line directly grounded must adopt the zero protection system, the metal shell of the electrical equipment must be connected with the special protection zero line, and the electrical equipment must be protected by zero; (2) The circuit switch box shall be provided with a leakage protector, and the electrical equipment shall be provided with a leakage protection device at the head end of the equipment load line, and each equipment shall implement the system of "one machine and one brake"; (3) The lamps should be protected by fuses, and the outdoor lighting should be protected by waterproofing; (4) The incoming and outgoing lines of the distribution box shall be protected with protective sheaths, doors and locks, and maintained and managed by special personnel to ensure that electricians hold relevant certificates; (5) The lighting voltage must be controlled below 36V in humid environment. 5, inventory storage (1) to eliminate fire hazards, it is necessary to set up obvious fire warning signs, strengthen fire prevention and specify the person in charge of fire prevention; (2) For inflammable and explosive articles (such as explosives, paints, oils, paints, isolators, etc.), a special warehouse shall be set up for storage, and a sound system for storage, storage, collection and recovery shall be established; (3) Ensure good ventilation. Forced ventilation is required in case of poor conditions. Matters needing attention in earthwork contracting are mainly problems needing attention in the process of construction, blasting and storage, with the aim of protecting the life safety of construction workers. In view of the poor safety awareness of employees, enterprise units need to train employees, and when they find violations of enterprise rules and regulations, they can adopt punishment regulations.
