Problems solved by technology

All the work of cast-in-place integrated pipe gallery, drainage ditches or flood ditches is completed on site, with many wet operations, serious environmental pollution, long construction period, difficult vibration, difficult construction quality control, large labor demand, and high formwork cost ;The full-section prefabricated comprehensive pipe gallery, drainage ditch or flood ditch is produced by the factory and assembled on site. The prefabricated components have large cross-sectional dimensions and heavy components, which makes it impossible to use the production line for production. The sections are short and there are many joints in the prefabricated components, and it is difficult to waterproof the joints

Embodiment 1

[0037] Such as figure 1 The shown single-chamber assembled integrated integrated pipe gallery, drainage ditch or flood ditch includes laminated exterior wall panels 1, laminated roof panels 3, laminated bottom panels 4 or cast-in-place bottom panels, and composite roof panels 3 include roof prefabricated layers and The top plate cast-in-place layer, the laminated bottom plate 4 includes the bottom plate prefabricated layer and the bottom plate cast-in-place layer, the cast-in-place bottom plate includes the bottom plate cast-in-place layer, and the laminated exterior wall panel 1 includes the exterior wall panel prefabricated layer and the exterior wall panel cast-in-place layer. The laminated base plate 4 or the cast-in-place base plate is set on the foundation cushion or the waterproof layer (or waterproof protection layer), and the prefabricated parts of all laminated components (the laminated base plate, the laminated top plate and the laminated outer wall panel) are equipp...

Embodiment 2

[0045] This embodiment is a two-cabin or three-cabin assembly integrated integrated pipe gallery, drainage ditch or flood ditch, see figure 2 , 3 , the structure difference from embodiment 1 is that the laminated inner wall panel 2 is added, such as Figure 5 , 10 As shown in , 11, the laminated interior wall panel 2 includes the prefabricated interior wall panel and the cast-in-place interior wall panel, and the interior wall panel prefabricated layer consists of the outer prefabricated panel 8 of the interior wall panel, the inner prefabricated panel 9 of the interior wall panel and the truss The upper and lower chords of the truss bars 7 are respectively pre-embedded in the two-layer prefabricated slabs and replace the corresponding vertical steel bars, and the vertical steel bars protruding from the lower ends of the inner and outer two-layer prefabricated slabs are bent and overlapped with each other The resulting return bars are anchored in the cast-in-place layer of ...

Abstract

The invention relates to the technical field of prefabricated concrete municipal structures. Proposed the assembly of integral integrated pipe gallery, drainage ditch or flood ditch, including laminated roof, laminated bottom or cast-in-place bottom and laminated exterior wall panels, laminated roof includes prefabricated roof layer and roof cast-in-place layer, laminated bottom Including the prefabricated floor of the bottom slab and the cast-in-place layer of the bottom slab, the cast-in-place bottom slab includes the cast-in-place layer of the bottom slab, and the laminated exterior wall panel includes the prefabricated exterior wall panel and the cast-in-place layer of the exterior wall panel; the laminated bottom slab or cast-in-place floor is set on the foundation cushion Or on the waterproof layer (or waterproof protective layer), configure steel bars on the prefabricated parts of all composite components. After the prefabricated parts are assembled on site, add the necessary force and structural steel bars, and pour concrete to form an assembled integrated integrated pipe gallery, drainage ditch or flood ditches. The invention can give full play to the advantages of on-site pouring and factory prefabrication, reduce on-site wet work, shorten the construction period, improve construction quality, ensure the integrity of the comprehensive pipe gallery, drainage ditch or flood ditch, and have good waterproof performance.

Description

technical field [0001] The invention relates to the technical field of prefabricated concrete municipal structures, in particular to an assembled integral integrated pipe gallery, drainage ditch or flood ditch. Background technique [0002] At present, there are mainly two methods for the construction of comprehensive pipe galleries, drainage ditches or flood ditches in China: one is the comprehensive pipe gallery, drainage ditches or flood ditches cast on site, and the other is the full-section prefabricated comprehensive pipe gallery and drainage ditches or flood ditches. All the work of cast-in-place comprehensive pipe gallery, drainage ditches or flood ditches is completed on site, with many wet operations, serious environmental pollution, long construction period, difficult vibration, difficult construction quality control, large labor demand, and high cost of formwork ;The full-section prefabricated comprehensive pipe gallery, drainage ditch or flood ditch is produced...
