Beijing Xicheng open hole professional company excavation you heard it? Know excavation role in it? So excavation should take those faceted support it? Today Beijing excavation company came eleven answer your questions! Excavation is to ensure the safety of underground structure construction and excavation of the surrounding environment, the sidewall of the pit and the surrounding environment using the retaining, strengthening and protection measures. Excavation role is to prevent a devastating slope displacement, while protecting basic structures built around the limb displacement. Should be taken in the pit of limb, pit wall, up and down the channel and pit support measures, here we do careful description: More Sharing URL: http://www.010dkm.com http://www . zyccgs.com pit construction must be carried limb protection. Depth of no more than 2M 1.2M limb can be high guard railing, construction pit deeper than 2M must also uses dense mesh safety net to do a closed protection. Limb protective railings distance from the mouth of the pit side shall not be less than 50cm. Set when the slope excavation pits to meet safety requirements. Pit wall supporting practices and important underground pipeline reinforcement measures must comply with the requirements of special construction and excavation program structure design. Supporting facilities produce localized deformation, the designer should be made in conjunction with the program and promptly take appropriate measures to adjust reinforcement. There must be a dedicated channel excavation for construction workers down. Channel settings, the structure must be solid and reliable, the number, location meet the construction requirements and comply with the relevant safety requirements. Pit edge bulldozers, piling material with the number and distance from the pit sides should comply with the relevant regulations and requirements of the construction program. When excavation construction machinery and equipment (slot) side distance does not comply with the relevant requirements and should be supported on the pit wall construction work within the scope of protection machinery according to the construction plan, to take effective measures, such as the ground. Excavation measures taken, the more our construction will be more safe, more secure, so do not too cumbersome procedures for excavation, all for our safety, in order to face accidents will happen!
