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

[0072] see figure 1 , Hollow-core wall panel mixed prefabricated integrated pipe gallery, which consists of cast-in-place bottom plate 1, double-sided prefabricated hollow core-filled side wall 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 ...

Embodiment 2

[0074] see figure 1 and Image 6 , according to the hollow-core wallboard hybrid prefabricated comprehensive pipe gallery 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

[0076] see figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 , according to the hollow-core wallboard hybrid 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 Steel bars are provided and the precast concrete layer 26 on the filling side is connected with the steel bars provided in the precast concrete layer 26 on the non-filling side through tie bars 9 and truss bars 20; the precast concrete layer on the filling side The prefabricated height of 25 is from the bottom of the base plate to the top of the top plate to facilitate waterproofing. The prefabricated height of the non-fill side prefabricated concrete layer 26 is from the top of the axil corner of the bottom plate to the bottom of the top plat...

Abstract

The invention discloses an air-cored wallboard mixed prefabrication assembly type compositive pipe gallery and a construction method thereof. The two ends of a cast-in-place bottom board are connected with the lower portions of two two-sided prefabricated hollow core-filling side walls correspondingly. The middle of the cast-in-place bottom board is connected with the lower portion of a total-prefabricated mid-partition. The two ends of a laminated top board are connected with the upper portions of the two two-sided prefabricated hollow core-filling side walls correspondingly. The middle of the laminated top board is connected with the upper portion of the total-prefabricated mid-partition. The advantages of prefabrication and cast-in-place techniques are combined, the self weight of prefabricated parts can be reduced through reasonable splitting, and the parts can be connected into a whole through cast-in-place core grouting, and the problem of prefabrication assembling of multi-cabin pipe galleries and pipe gallery nonstandard sections can be solved.

Description

technical field [0001] The invention relates to a comprehensive pipe gallery, in particular to a hollow-core wallboard mixed prefabricated comprehensive pipe gallery. The invention also relates to a construction method of the hollow-core wallboard mixed prefabricated comprehensive pipe gallery. 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,...
