[0025] Example 1

[0026] It includes a main structure of an integrated pipe gallery 1 and an embedded rubber waterstop 2. The main structure of the pipe gallery is cast-in-place reinforced concrete. A part of the embedded rubber waterstop is buried in the concrete of the main structure of the integrated pipe gallery, and the other part protrudes from the end face of the main structure of the integrated pipe gallery. The ends of the embedded rubber waterstop are connected and closed to form a ring.

[0027] It also includes a protective structure 3, a filler 4, a connecting fastener 5, and a waterproof sealing layer 6. The shape and size of the protective structure match the shape and size of the end face of the main structure of the integrated pipe gallery. A number of connecting fasteners are arranged between the outer wall surface of the protective structure and the outer wall surface of the main structure of the integrated pipe gallery, and between the inner wall surface of the protective structure and the inner wall surface of the main structure of the integrated pipe gallery (specifically arranged around the inner wall surface of the protective structure and the main structure of the integrated pipe gallery, and the top surface and two side surfaces of the outer wall surface of the protective structure and the main structure of the integrated pipe gallery), so that the protective structure fits on the end face of the main structure of the integrated pipe gallery; a groove is provided on the fitting surface of the protective structure and the main structure of the integrated pipe gallery, the design position of the groove matches the protruding position of the embedded rubber waterstop, and the depth of the groove is greater than the protruding length of the embedded rubber waterstop; the groove and the end face constitute a closed cavity, the embedded rubber waterstop is placed in the closed cavity, the filler is arranged in the closed cavity, and wrapped around the embedded rubber waterstop; the waterproof protective layer is covered outside the connecting seam between the protective structure and the main structure of the integrated pipe gallery.

[0028] In this embodiment, a protective structure is added that matches the shape and continuity of the end face of the main structure of the integrated pipe gallery, and a groove is set on the protective structure; the protective structure is fixed to the end face of the main structure of the integrated pipe gallery by a number of connecting fasteners, so that the groove and the end face of the main structure of the integrated pipe gallery form a closed cavity. The formed closed cavity and filler are used to wrap and seal the embedded rubber waterstop protruding from the end face of the main structure of the integrated pipe gallery. A waterproof covering layer is set outside the connection seam between the protective structure and the main structure of the integrated pipe gallery to further waterproof and seal the closed cavity.

[0029] Based on the above structure, the protruding part of the buried rubber waterstop is avoided from being exposed when the construction interval is long, and the aging of the protruding part of the rubber waterstop by ultraviolet rays, air, water and other media is effectively isolated, ensuring the waterproof effect of the rubber waterstop during long-term use after the construction is completed; in addition, the protective structure is easy to dismantle and will not cause damage to the rubber waterstop during the dismantling process.

[0030] Example 2

[0031] The structure and principle of the second embodiment are similar to those of the first embodiment, except that a protection structure is provided. Figure 1-4 As shown, the protection structure is composed of a plurality of U-shaped protection prefabricated blocks, and a filling inlet is provided on one of the U-shaped protection prefabricated blocks. The filling is filled after one of the U-shaped protection prefabricated blocks is installed, and after the filling is completed, the next U-shaped protection prefabricated block is installed; the U-shaped protection prefabricated block with the filling inlet is installed last, and the filling is applied to the last U-shaped protection prefabricated block through the filling inlet, and then the filling inlet is blocked with a waterproof protective layer.

[0032] Example 3

[0033] The structure and principle of Example 3 are similar to those of Example 1, and the differences are as follows: another implementation form of the protection structure is provided, which is not shown in the figure; the protection structure adopts an annular integral part, and a plurality of filler injection ports are provided on the annular integral part.

[0034] Example 4

[0035] The structure and principle of Example 4 are similar to those of Example 2 or 3, and the difference is that: preferably, the thickness of each side of the protection structure is the same as the thickness of the corresponding main structure of the integrated pipe gallery. Of course, if the thickness of each side of the protection structure is different from the thickness of the main structure of the integrated pipe gallery, it is also within the protection scope of this application, as long as the size and position of the groove match the size and position of the protruding part of the rubber water stop.

[0036] In Example 4, the fastening connector includes multiple pairs of expansion bolts 5-1 and long strips 5-2; the long strips are arranged outside the connection seam between the protection structure and the main structure of the integrated pipe gallery, and a single long strip is simultaneously attached to the outer wall surface or the inner wall surface of the protection structure and the main structure of the integrated pipe gallery; the two ends of the long strips are respectively fixed to the outer wall surface or the inner wall surface of the protection structure and the main structure of the integrated pipe gallery by expansion bolts.

[0037] In this embodiment, after the end faces of the protective structure and the main structure of the utility corridor are fitted together (if the protective structure is composed of multiple U-shaped protective prefabricated blocks, the end faces of a single U-shaped protective prefabricated block and the main structure of the utility corridor are fitted together), the same long strip pressure strip is fixed to the inner wall or outer wall of the protective structure and the main structure of the utility corridor by expansion bolts to achieve a fastening connection between the two. In addition, there is no need to set fastening connectors for the ground of the main structure of the utility corridor and the ground of the protective structure. Among them, the long strip pressure strip is made of galvanized steel plate or galvanized flat iron.

[0038] In Examples 1-4, the protective structure is made of prefabricated concrete blocks, polypropylene, autoclaved aerated blocks, or prefabricated glass fiber blocks. The filler is foamed glue. The waterproof seal layer is made of waterproof mortar or waterproof membrane.

[0039] The above are only preferred embodiments of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of patent application of the present invention still fall within the protection scope of the present invention.
