The polyurea has better seepage-proofing capability and deformation capability, has good adhesive force with concrete, and can effectively prevent the water-stopping structure from being separated from the pipe gallery. The utility model discloses simple and practical type, construction convenience, stagnant water are respond well, can effectively solve when prefabricated piping lane stagnant water destroys to the problem of gap infiltration between the piping lane appears.
Description
Technical Field
The utility model relates to an underground pipe gallery stagnant water structure, especially a stagnant water structure between prefabricated pipe gallery gap of underground pipe gallery.
Background
When utility tunnel adopted the prefabricated construction, stagnant water structure often need be done to two section pipe gallery structure positions. If the treatment is not good, the operation management of the pipe gallery is inconvenient due to water seepage or water leakage. Wherein, the waterproof coiled material of present most underground pipe gallery parting department, but the waterproof coiled material has a lot of shortcomings, and the main performance is in that the coiled material life-span is shorter, and on the other hand because water can flow in the coiled material is inside, the concrete position of leaking is difficult to confirm to the condition of leaking.
Therefore, how to improve the problem of stagnant water between the piping lane, guarantee the safe operation of piping lane, be the problem that needs to solve urgently.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a stagnant water structure between the prefabricated piping lane gap of underground pipe gallery is provided, easily construction can effectively stagnant water, avoids appearing the problem of leaking, guarantees the safe operation of piping lane.
In order to solve the technical problem, the utility model discloses a technical scheme is: the utility model provides a stagnant water structure between prefabricated pipe gallery gap of underground pipe gallery, "T" type rubber slab floor inserts in the gap position of two sections adjacent prefabricated pipe galleries from the pipe gallery outside, "T" type rubber slab both sides pterygoid lamina spanes the gap position and bonds on the surface of two sections prefabricated pipe galleries, "the hole board is closed in two sections prefabricated pipe galleries gaps intussuseption of T" type rubber slab floor inboard, "the geotechnological cloth layer has been laid to T" type rubber material pterygoid lamina outside, the polyurea layer that is used for sealing the stagnant water structure has been laid to the geotechnological cloth layer outside.
The thickness of polyurea layer is 4 ~ 6 mm.
And two end parts of wing plates on two sides of the T-shaped rubber plate are provided with corner trims.
The utility model has the advantages that: the T-shaped rubber material has good elasticity, wear resistance, aging resistance and tear resistance, and has good deformation capability suitable for pipe corridors. The high-pressure closed pore plate is arranged in the pipe gallery seam, plays a role of filling the seam, and has small density and high expansion strength. The high-strength fine-woven geotextile has high tensile strength and tear strength. The polyurea has excellent waterproof performance and tensile deformation performance, and has good adhesive force with concrete. This stagnant water structure construction convenient and fast, the stagnant water is respond well, effectively solves prefabricated piping lane stagnant water problem.

Figure 1 is the utility model discloses the schematic diagram of stagnant water structure between the prefabricated piping lane gap of underground pipe gallery.
Detailed Description
In order to understand the technical features, objects and effects of the present invention more clearly, the following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings:
as shown in fig. 1, the utility model discloses a stagnant water structure between prefabricated pipe gallery gap of underground pipe gallery, insert two sections adjacent prefabricated pipe gallery 1's gap position from the pipe gallery outside in the 3 floor boards of "T" type rubber slab, "3 both sides pterygoid lamina of" T "type rubber slab spanes the gap position and bonds on two sections prefabricated pipe gallery 1's surface," the closed orifice board 6 of the intussuseption in 1 gap of two sections prefabricated pipe galleries of 3 floor insides of "T" type rubber slab, "the geotechnological cloth layer 4 has been laid in the 3 pterygoid lamina outsides of" T "type rubber material, the polyurea layer 5 that is used for sealing the stagnant water structure has been laid in the 4.
The thickness of polyurea layer 5 is 4 ~ 6 mm.
Two end parts of wing plates on two sides of the T-shaped rubber plate 3 are provided with corner trims.
The T-shaped rubber material has the characteristics of good elasticity, wear resistance, aging resistance, tear resistance, strong adaptive deformability, good waterproof performance and the like.
The closed pore plate is characterized by small density, high expansion strength, low surface water absorption and good permeability resistance.
The geotextile is arranged on the upper part of the T-shaped rubber plate, and the material has high tensile strength and tear strength.
The polyurea is scraped by hand, and the thickness of the polyurea is 4-6 mm. The polyurea has good anti-seepage effect, good flexibility at low temperature, lower requirement on environmental conditions, insensitivity to moisture and humidity and no influence of environmental temperature and humidity on construction. Excellent water resistance, chemical corrosion resistance, aging resistance and other performances, and the performances are not reduced after the paint is soaked in media such as water, acid, alkali, oil and the like for a long time. The polyurea material and the concrete have good adhesive force.
In the piping lane installation, the gap is generally controlled between 1.5 ~ 2.0mm between two sections prefabricated piping lanes 1, inserts 3 floor parts of "T" type rubber slab in the gap between prefabricated piping lane 1, and the pterygoid lamina part adopts glue 2 to paste on prefabricated piping lane 1, both can play the stagnant water effect, the deformation between the adaptable piping lane again. And filling a closed pore plate 6 in gaps among other prefabricated pipe galleries 1 to serve as a gap filling material in the gaps. In order to enhance the reliability of water stopping, a geotechnical cloth layer 4 is arranged on the upper portion of a wing plate of the T-shaped rubber plate 3, and a polyurea layer 5 with the thickness of 4-6 mm is scraped on the geotechnical cloth layer 4 by hand, so that the anti-seepage water stopping effect is improved. This structure "T" type rubber slab 3 and polyurea layer 5 all have the ability that adapts to great deformation, can be suitable for the deformation between prefabricated piping lane 1, and polyurea layer 5 has fine adhesive force with the concrete, can prevent effectively that stagnant water and prefabricated piping lane 1 from breaking away from, has effectively solved the problem of stagnant water between the prefabricated piping lane, has guaranteed the piping lane safe operation.
The above-mentioned embodiments are only used for illustrating the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention accordingly, the scope of the present invention should not be limited by the embodiment, that is, all equivalent changes or modifications made by the spirit of the present invention should still fall within the scope of the present invention.
