Superimposed assembly type construction comprehensive pipe rack and construction method thereof

Abstract

The invention discloses a superimposed assembly type construction comprehensive pipe rack and a construction method thereof. The comprehensive pipe rack is formed by combining a plurality of superimposed assembling plates, wherein the superimposed assembling plates are prefabricated superimposed assembling plates. The superimposed assembling plates each adopt hollow structure design with block-superimposed. Connecting joints of horizontal members and vertical members and connecting joints between the horizontal members all adopt reserved steel bar superimposed cast-in-place connection. Concrete is poured to connect the hollow structures between the superimposed assembling plates to form the comprehensive pipe rack with an integral structure. The superimposed assembling plates is temporarily fixed by using double diagonal bracing connection, and after longitudinal stagnant water steel plates and circumferential stagnant water steel plates are installed and joint steel bars are bound, self-compacting concrete is poured to the hollow structure part. The superimposed assembly type construction comprehensive pipe rack can effectively increase the working surface, creates flow process conditions, speeds up the construction progress, reduces the resource input such as on-site support erection, conforms to green construction, can effectively reduces the cost, and improves the waterproof performance of the structure.

Description

technical field [0001] The invention relates to the technical field of highway bridge construction, in particular to a prefabricated pipe gallery structure, especially suitable for the construction of comprehensive pipe gallery structures with limited operating environment, tight construction period requirements and high environmental protection requirements, and any multi-cabin form of cast-in-place or prefabricated The construction of comprehensive pipe gallery. Background technique [0002] The comprehensive pipeline corridor (called "common ditch" in Japan and "common pipeline" in Taiwan) is the comprehensive corridor of underground urban pipelines. That is to build a new space structure underground in the city, integrating various engineering pipelines such as power, communication, gas, heating, water supply and drainage, etc., and implement unified planning, unified design, unified construction and management. In many large and medium-sized cities in my country Has bee...

Problems solved by technology

[0003] At present, the main construction methods of the existing comprehensive pipe gallery in China are cast-in-place and prefabrication. The conventional cast-in-place method often requires a large amount of formwork, scaffolding and other materials, and requires a lot of manual and mechanical cooperation. The appearance quality of the structure, The waterproof performance and the location of embedded parts are not easy to guarantee during the construction process, and there are many safety risk control factors during the construction process; the integral assembly of the prefabricated pipe gallery will be restricted by the construction site, and there are high requirements for its hoisting and transportation, and General waterproof performance

[0004] As mentioned above, the existing construction method of comprehensive pipe gallery has a long construction period, large resource investment and high cost, and does not conform to the green construction advocated by the state. The construction method of the comprehensive pipe gallery structure that meets the limited operating environment, tight construction period requirements and high environmental protection requirements has become the top priority to promote the development of comprehensive pipe gallery
