Utility tunnel and construction method thereof

Abstract

The invention discloses a utility tunnel and a construction method thereof. The utility tunnel comprises a horizontal arranged rectangular base plate, a rectangular top plate horizontally arranged above the rectangular base plate, and two corrugated compound walls vertically arranged between the rectangular base plate and the rectangular top plate, and the two corrugated compound walls are symmetrically arranged on the left side and the right side of the rectangular base plate respectively; the rectangular base plate, the rectangular top plate and the corrugated compound walls surrounds a tunnel channel. The construction method comprises the steps of digging a foundation pit where the construction tunnel locates, assembling boards, pouring concrete and back-filling the foundation pit. According to the utility tunnel, the corrugated compound walls are adopted for the side walls, and protruding portions of the corrugated compound walls have the effect of constructional columns. According to the construction method of the utility tunnel, concrete pouring is conducted on the scene, and joint cracks between tunnel segments are avoided.

Description

technical field [0001] The invention belongs to the technical field of construction of a comprehensive pipe gallery, and in particular relates to a comprehensive pipe gallery and a construction method thereof. Background technique [0002] At present, my country's comprehensive pipe gallery technology is mainly cast-in-place structure and prefabricated structure. Among them, the cast-in-place structure adopts the traditional house construction method, and the technological process is steel bar binding, formwork support, pouring and vibration. Because, there are generally problems such as long construction period, large resource consumption, significant impact by weather, great damage to the surrounding environment, and difficulty in guaranteeing construction quality. The prefabricated structure is to prefabricate the comprehensive pipe gallery in sections, and then transported to the construction site by a transport vehicle for assembly. Its materials are mainly steel bars an...

Problems solved by technology

[0002] At present, my country's comprehensive pipe gallery technology is mainly cast-in-place structure and prefabricated structure. Among them, the cast-in-place structure adopts the traditional house construction method, and the technological process is steel bar binding, formwork support, pouring and vibration. Because, there are generally problems such as long construction period, large resource consumption, significant impact by weather, great damage to the surrounding environment, and difficulty in guaranteeing construction quality.

The prefabricated structure is to prefabricate the comprehensive pipe gallery in sections, and then transported to the construction site by a transport vehicle for assembly. Its materials are mainly steel bars and concrete. It is characterized by convenient construction and short construction period, but there are many joints. Difficulty in assembly technology and complex joint waterproofing process and its large tonnage, limited transportation height and difficulties in the transportation process
