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 Construction
[0040] The specific implementation of a prefabricated integrated pipe gallery spliced with cast-in-place concealed beams and laminated slabs and its construction method will be described in detail below in conjunction with the accompanying drawings and specific examples.
[0041] Such as Figure 1 to Figure 9 As shown, a prefabricated integrated pipe gallery spliced with cast-in-place concealed beams and laminated slabs includes a multi-section integrated pipe gallery body. The two ends and the middle part of the cast-in-place bottom plate 1 are reserved with U-shaped ribs 5 on the side facing the full prefabricated partition wall, and the upper and lower ends of the full prefabricated partition wall 2 are equipped with U-shaped ribs. Type inserting ribs 5, the cast-in-place bottom plate 1 and the fully prefabricated partition wall 2 are overlapped and connected by U-shaped inserting ribs 5, and the two ends and the middle part of the superimposed top plate 3 are respectiv...

The invention provides a cast-in-place hidden beam and superimposed plate splicing prefabricated assembly type comprehensive pipe gallery and a construction method for the cast-in-place hidden beam and superimposed plate splicing prefabricated assembly type comprehensive pipe gallery. The comprehensive pipe gallery comprises a plurality of comprehensive pipe gallery bodies, and each comprehensivepipe gallery body is formed by splicing a cast-in-place bottom plate, fully-prefabricated partition walls and a superimposed top plate. The construction method comprises the steps of prefabricated component fabricating, positioning and line placing, bottom plate steel bar binding, bottom plate casting, maintaining and mold releasing, then prefabricated component assembling, splicing joint steel bar and moldboard installing and splicing and cast-in-place part concrete casting, and the prefabricated assembly integral type concrete comprehensive pipe gallery is formed. By means of the cast-in-place hidden beam and superimposed plate splicing prefabricated assembly type comprehensive pipe gallery and the construction method for the cast-in-place hidden beam and superimposed plate splicing prefabricated assembly type comprehensive pipe gallery, the advantages of prefabricating and cast-in-place processes are colligated, the own weight of the prefabricated components can be reduced through reasonable separation, construction hoisting is facilitated, all components can also be connected into a whole by casting the cast-in-place hidden beams in place, and under the premise that the overallbearing capacity and deformation capacity of the comprehensive pipe gallery are not reduced, the prefabricating and assembling problems of multi-cabin pipe galleries and pipe gallery non-standard sections can be solved.
Description
technical field [0001] The invention relates to a prefabricated integrated pipe gallery spliced with cast-in-situ concealed beams and laminated slabs and a construction method thereof. 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 ...
