Municipal pipeline groove supporting structure and method

Abstract

The invention provides a municipal pipeline groove supporting structure. The municipal pipeline groove supporting structure is characterized in that the municipal pipeline groove supporting structurecomprises two sets of enclosure plates, a plurality of sets of stand columns and a plurality of sets of truss mechanisms; the two sets of enclosure plates are arranged on the two sides of a foundationditch side by side; each enclosure plate comprises a plurality of sets of spliced enclosure plate units; each enclosure plate unit comprises a rectangular base plate and wing plates symmetrically arranged at the ends of the two sides of the base plate in the length direction, and the two wing plates are provided with a plurality of through holes allowing the stand columns to pass through in an array correspondingly; the stand columns vertically penetrate through the multiple sets of vertical enclosure plate units to be arranged on the two sides of the foundation ditch in an array; and the truss mechanisms are detachably arranged between the adjacent enclosure plate units on the two sides of the foundation ditch.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a municipal pipe groove support structure. Background technique [0002] Municipal pipeline installation methods are divided into slotted construction and non-grooved construction. The trenching construction needs to excavate the pipe trench first. In order to prevent the foundation pit from collapsing, the excavation of the pipe trench needs to take slope and support measures according to the geological conditions, excavation depth, surrounding environment, underground pipelines, groundwater and other conditions. The commonly used support measures for excavation without setting slopes are wooden sheet piles and steel sheet piles. The wooden sheet pile support structure mainly uses wooden boards as maintenance components, and cooperates with supporting components to achieve the purpose of slope support; steel sheet piles use section steel and steel plates as mainte...

AI Technical Summary

Problems solved by technology

[0004] (1) Steel sheet piles are suitable for foundation pits with poor foundation pit conditions. The steel sheet piles are self-heavy and require special machinery for construction. The project cost is high, the construction period is long, the process requirements are high, and the construction is difficult

[0005] (2) Wooden sheet piles are suitable for foundation pit support with relatively shallow and good soil conditions. Wooden sheet piles are used as a support system. Wooden sheet piles have poor waterproof performance, less turnover times, and waste and consume wood resources.
