Problems solved by technology

The traditional pipe gallery is made of concrete, which is cumbersome and time-consuming. However, if the pipe gallery is made of polymer plastic, it has the advantages of quick and efficient installation, environmental protection, high strength, good water resistance, flame retardancy, and anti-aging.

Embodiment 1

[0041] The direction of the corridor body is longitudinal, and the direction perpendicular to the direction of the corridor body is horizontal. see figure 1 , this embodiment discloses a polymer plastic fabricated pipe gallery: comprising a bottom plate 3 and a top plate 8 , and frame components arranged between the bottom plate 3 and the top plate 8 .

[0042] The bottom plate 3 is a polymer plastic plate. The lower surface of the bottom plate 3 is a rough surface. The bottom plate 3 is laid on the bottom cushion of the pipe gallery. The bottom cushion layer of the pipe gallery includes a clay layer, a crushed stone layer and a silt layer sequentially from top to bottom. The bottom plate 3 is laid on the clay layer and compacted.

[0043] The frame members are arranged longitudinally at intervals. Each frame part includes two columns 5 and a beam 7 erected between the two columns 5 . Both the column 5 and the beam 7 are made of polymer plastics. see figure 2 , the co...

Embodiment 2

[0048] This embodiment discloses a construction method for the polymer plastic prefabricated pipe gallery described in Embodiment 1, which includes the following steps:

[0049] 1) Clean up and level the site according to the requirements of the construction site.

[0050] 2) Use excavating machinery to excavate the foundation pit, and carry out foundation pit support at the same time.

[0051] 3) Construction cushion: check the groove of the foundation pit, eliminate loose soil, weak soil layers and cavities, and perform bottom tamping twice to make the foundation pit smooth and clean. According to the design requirements, the location of the pipe gallery is determined by setting out the construction line, and the interior of the pipe gallery is filled with silt, gravel and clay in sequence, and compacted to form a cushion at the bottom of the pipe gallery.

[0052] 4) Lay the bottom plate 3 above the bottom cushion of the pipe gallery and compact it.

[0053] 5) Lift the c...

Abstract

The invention provides a high-molecular plastic assembly type pipe gallery and a construction method thereof. The assembly type pipe gallery comprises a bottom plate, a top plate and a plurality of frame components arranged between the bottom plate and the top plate. The bottom plate is paved on a cushion layer at the bottom of the pipe gallery. The top plate is arranged above the bottom plate inparallel. The frame components, the bottom plate, side plates and the top plate define a pipe gallery channel. The construction method of the assembly type pipe gallery comprises the steps of site leveling, foundation pit excavation, cushion layer construction, bottom plate installation, stand column construction, side plate installation, cross beam installation, top plate installation, water stoptreatment, soil mass backfilling and the like. The assembly type pipe gallery adopts industrialized large-scale production and mechanized construction, and is high in efficiency, short in construction period and low in construction cost. The pipe gallery is good in structural integrity, a seepage path is additionally arranged, and thus the good seepage prevention performance is achieved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to an assembled comprehensive pipe gallery and a construction method thereof. Background technique [0002] In recent years, my country's cities have continued to develop, and various municipal pipe network facilities have also been continuously expanded, increased, repaired, and updated, resulting in municipal construction sites everywhere in the city, and frequent excavation and repair of roads in many cities. Re-excavation and re-repair not only cause inconvenience to the normal life of residents, but also bring other social impacts such as environmental pollution, urban traffic congestion, and loss of commercial interests. This has become a bottleneck restricting the development of urban infrastructure and the improvement of the environment. As a new model that is more effective in solving the contradictions in urban infrastructure construction, the comprehensive pipe corri...
