Abstract
The invention discloses a gas pipeline protection film bag cofferdam construction method, and belongs to the field of building construction.The gas pipeline protection film bag cofferdam construction method comprises the steps that film bags are sequentially paved along the axis of a cofferdam, during paving, the adjacent film bags are partially overlapped, a plurality of timber piles are driven into the two sides of each film bag in the length direction of the cofferdam, and the adjacent timber piles are arranged on the two sides of the cofferdam; the position of the timber pile is positioned through a total station, and after the timber pile is fixed, the two sides of the film bag are tied to the timber pile through ropes; the film bags are subjected to trial sand filling, the film bags are subjected to sand filling according to parameters obtained through trial sand filling, film bag sand is prepared, all film bag layers are sequentially subjected to sand filling from bottom to top, and for each film bag layer, the film bags are sequentially subjected to sand filling in the direction away from the gas pipe from the film bag close to the gas pipe; sewing a sand filling cuff of the film bag sand through a portable sewing machine; the top face of the film bag sand serves as a construction face, and a plurality of plastic drainage plates are inserted through a crawler-type plate inserting machine.
Description
technical field [0001] The invention relates to the field of building construction, in particular to a construction method for a gas pipeline protective film bag cofferdam. Background technique [0002] In recent years, my country's urban gas has developed rapidly, with a population of 540 million gas users. However, the safety risks in the operation of urban gas pipeline networks are becoming more and more serious, and accidents occur frequently. Such accidents have caused a large number of casualties and economic losses, and have aroused great attention from all walks of life to the safety of urban gas pipeline networks. Site filling is likely to affect the adjacent high-pressure gas pipelines, and there is a risk of gas accidents. Contents of the invention [0003] The purpose of the present invention is to at least solve one of the technical problems existing in the prior art. For this reason, the present invention proposes a method for the construction of gas pipelin...
