Abstract

The invention discloses an application method of construction method pile enclosing to a comprehensive pipe gallery foundation pit. The method mainly comprises the steps of construction setting out, guide groove excavation, positioning, drilling machine in-position operation, slurry mixing and guniting stirring, H steel machining and H steel inserting, cleaning of mud in a groove and constructionrecord settlement. The problems of poor anti-permeability, the tight project schedule, the large surrounding influence and underground space waste can be solved, through circular use of H steel, the resource use rate is improved, and the problems that the cost is high, and a permanent enclosing structure causes the underground space resource pollution are solved.

Description

technical field [0001] The invention relates to the field of building construction methods, in particular to an application method of construction method pile enclosure in the foundation pit of a comprehensive pipe gallery. Background technique [0002] The foundation pit project is the first link in the implementation of the comprehensive pipe gallery project. The design of the foundation pit enclosure is related to the safety and progress of the pipe gallery structure during construction, and also has a great impact on the overall cost of the project. The excavation depth of the foundation pit is an important factor affecting the design of the enclosure structure of the comprehensive pipe gallery. When designing the longitudinal section of the comprehensive pipe gallery, the roof covering soil of the structure needs to consider the requirements of road paving, green planting, crossing of lateral branch pipes of the road, and layout of node interlayers. Usually the covering...
