Problems solved by technology

The integral prefabricated pipe gallery has the advantages of good integrity and simple installation process, but there are problems such as large size and weight of a single section, difficult transportation and hoisting, and waterproof joints are not safe.
However, most of the existing prefabricated pipe gallery structures have poor integrity due to the large number of assembled components, and are prone to defects such as structural damage at the joints, damage to sealing materials, or aging of the pipe gallery, resulting in water seepage in the pipe gallery.

Embodiment 1

[0066] see figure 1 , prefabricated integrated pipe gallery with hollow wall panels, consisting of cast-in-place bottom plate 1, double-sided prefabricated hollow core-filled side walls 2, fully prefabricated middle partition wall 3 and laminated roof 4. The two ends of the cast-in-place base plate 1 are respectively connected to the lower parts of two double-sided prefabricated hollow core-filled side walls 2, the middle part of the cast-in-place base plate 1 is connected to the lower part of the fully prefabricated middle partition wall 3, and the two ends of the superimposed top plate 4 are respectively connected to the The upper parts of the two double-sided prefabricated hollow core-filled side walls 1 are connected, and the middle part of the superimposed roof 4 is connected with the upper part of the fully prefabricated middle partition wall 3 . The joint between the double-sided prefabricated hollow core-filled side wall 2 and the cast-in-place base plate 1 is provided...

Embodiment 2

[0068] see figure 1 and Figure 5 , according to the prefabricated comprehensive pipe gallery with hollow wall panels described in Embodiment 1, the cast-in-place bottom plate 1 is provided with vertically bent steel bars 14 . The vertically bent steel bar 14 extends into the double-sided prefabricated hollow core-filled side wall 2, and reaches the anchorage length requirement.

Embodiment 3

[0070] see figure 1 , image 3 , Figure 6 , Figure 8 and Figure 9 , according to the hollow wall panel mixed prefabricated integrated pipe gallery described in embodiment 2, the structure of the double-sided prefabricated hollow core-filled side wall 2 is: the precast concrete layer 25 on the filling side and the precast concrete layer 26 on the non-filling side are set There are steel bars and the precast concrete layer 25 on the filling side and the steel bars provided in the precast concrete layer 26 on the non-filling side are connected by tie bars 9; the prefabricated height of the precast concrete layer 25 on the filling side is from the bottom of the bottom plate to the top of the roof; The prefabricated height of the prefabricated concrete layer 26 on the non-filling side is from the top of the axil corner of the bottom slab to the bottom of the axillary corner of the top slab; The prefabricated concrete layer 26 on the filling side is poured together, and the c...

Abstract

The invention discloses a hollow-wallboard mixed-prefabricated type comprehensive pipe rack and a construction method thereof. The hollow-wallboard mixed-prefabricated type comprehensive pipe rack is characterized in that two ends of a cast-in-place baseboard are respectively connected with lower portions of two double-sided prefabricated hollow-wallboard filling-core side walls, the middle portion of the cast-in-place baseboard is connected with the lower portion of a total-prefabricated middle partition, two ends of a overlapped roof are respectively connected with upper portions of the two double-sided prefabricated hollow-wallboard filling-core side walls, and the middle portion of the overlapped roof is connected with the upper portion of the total-prefabricated middle partition. Advantages of prefabrication and cast-in-place technologies are integrated, the hollow-wallboard mixed-prefabricated type comprehensive pipe rack can be disassembled reasonably, dead load of prefabricated components is lowered, the components can be integrally connected through cast-in-place grouting, and the problem about difficulty in prefabrication and assembly construction of multi-cabin pipe rack and pipe rack non-standard pieces can be solved.

Description

technical field [0001] The invention relates to a novel prefabricated integrated pipe gallery and a construction method. Background technique [0002] The urban underground comprehensive utility gallery is an underground space structure where various pipelines such as electric power, communication, gas, water supply, and drainage are concentrated. It solves the traffic congestion caused by the "zip link", avoids the "spider web" in the air, plays a positive role in improving the overall image of the city and creating a harmonious ecological environment in the city, and has attracted great attention from all over the country. [0003] The traditional all-in-place pipe gallery construction method requires processes such as steel bar processing and binding, formwork support, concrete pouring, maintenance, and formwork removal for the overall structure of the pipe gallery on the construction site. Not only is the construction process complicated, the construction period is long,...
