Description

Technical Field

[0001] The utility model relates to a waterproof sleeve construction structure for a pipeline passing through the top plate of a pipe gallery, belonging to the technical field of pipe gallery construction. Background Technique

[0002] During the construction of the pipe gallery, in order to introduce power cables, communication cables, etc. into the pipe gallery, pipe holes are usually pre-opened at the top of the pipe gallery. After the installation of the pipe conduits is completed, the gaps between the pipe conduits and the pipe holes are sealed. However, leakage often occurs at the pipe holes due to improper sealing.

[0003] The Chinese patent document with the publication number CN111963779A discloses a waterproof structure for a floor sleeve node, including: a pre-embedded sleeve, which penetrates through the structural wall; a waterproof layer, which is arranged on the outer side of the structural wall; a first seal, which is arranged between the pre-embedded sleeve and the decorative surface layer arranged outside the waterproof layer; a second seal, which is arranged between the pre-embedded sleeve and the floor sleeve; the waterproof layer is a mortar waterproof layer, and the surfaces of the first seal and the second seal are coated with a coating containing a PTFE-based coating material; the thickness of the coating is 0.5-5um. Through the combined action of the waterproof layer, the first seal and the second seal, the sealing performance of the floor sleeve is ensured, and the technical problem of water seepage at the floor sleeve node is effectively solved.

[0004] The pre-embedded sleeve in this waterproof structure needs to be constructed simultaneously with the structural wall. When it is applied to the pipe gallery, the positioning and installation of the pre-embedded sleeve will interfere with the formwork support of the pipe gallery, affecting the construction period of the pipe gallery prefabrication. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a waterproof sleeve construction structure for a pipeline passing through the top plate of a pipe gallery.

[0006] The utility model is achieved through the following technical solutions:

[0007] A waterproof sleeve construction structure for a pipeline passing through the top plate of a pipe gallery, including a pipe gallery top plate, a waterproof sleeve and a pipe conduit. A pipe hole is opened on the pipe gallery top plate. The waterproof sleeve penetrates through the pipe hole, and fine aggregate concrete is filled between the waterproof sleeve and the pipe hole. A waterproof layer is jointly laid on the fine aggregate concrete and the pipe gallery top plate. The pipe conduit penetrates through the waterproof sleeve, and flexible filler is filled between the pipe conduit and the waterproof sleeve.

[0008] The strength of the fine aggregate concrete is C20.

[0009] The pipe hole, the waterproof sleeve and the pipe conduit are coaxially arranged.

[0010] A waterproof wing ring is arranged on the outer wall of the waterproof sleeve, and the waterproof wing ring is located in the fine aggregate concrete.

[0011] The lower end of the waterproof sleeve is flush with the bottom surface of the pipe gallery roof, and the upper end extends above the pipe gallery roof.

[0012] The waterproof layer is a mortar waterproof layer.

[0013] A surface layer is laid on the waterproof layer.

[0014] The flexible filler is asphalt or water-swelling waterstop rubber.

[0015] At the upper end surfaces of the waterproof sleeve and the flexible filler, caulking is carried out with waterproof ointment.

[0016] The beneficial effects of the present utility model are as follows: The construction method of first erecting formwork to precast the pipe gallery and then opening holes on the pipe gallery roof to install the waterproof sleeve is adopted. The positioning and installation of the waterproof sleeve will not interfere with the construction such as erecting formwork and pouring concrete of the pipe gallery, ensuring the construction period of precasting the pipe gallery. The combined action of the waterproof layer and the flexible filler ensures the sealing performance at the installation positions of the waterproof sleeve and the threading pipe, avoiding water seepage at this place.

[0018] In the figure: 1 - pipe gallery roof, 2 - fine aggregate concrete, 3 - flexible filler, 4 - threading pipe, 5 - waterproof sleeve, 6 - waterproof wing ring, 7 - waterproof layer, 8 - waterproof ointment, 9 - surface layer. Detailed Embodiment

[0019] The technical solution of the present utility model will be further described below, but the scope of protection claimed is not limited thereto.

[0020] As Figure 1 shown, a waterproof sleeve construction structure for a pipeline passing through the pipe gallery roof of the present utility model includes a pipe gallery roof 1, a waterproof sleeve 5 and a threading pipe 4. A pipe passing hole is opened on the pipe gallery roof 1. The waterproof sleeve 5 passes through the pipe passing hole, and fine aggregate concrete 2 is filled between the waterproof sleeve 5 and the pipe passing hole. A waterproof layer 7 is jointly laid on the fine aggregate concrete 2 and the pipe gallery roof 1. The threading pipe 4 passes through the waterproof sleeve 5, and a flexible filler 3 is filled between the threading pipe 4 and the waterproof sleeve 5. The construction method of first erecting formwork to precast the pipe gallery and then opening holes on the pipe gallery roof 1 to install the waterproof sleeve 5 is adopted. The positioning and installation of the waterproof sleeve 5 will not interfere with the construction such as erecting formwork and pouring concrete of the pipe gallery, ensuring the construction period of precasting the pipe gallery. The combined action of the waterproof layer 7 and the flexible filler 3 ensures the sealing performance at the installation positions of the waterproof sleeve 5 and the threading pipe 4, avoiding water seepage at this place.
