[0027] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.
[0028] Secondly, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures or characteristics that may be included in at least one implementation manner of the present utility model. The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.
[0029] Embodiment 1
[0030] Refer to Figures 2 to 6 , which is the first embodiment of the present utility model. This embodiment provides a bridging structure for plugging leaks in the basement connecting port floor. The bridging structure for plugging leaks in the basement connecting port floor includes a plugging component 200, a sealing component 300, and a main body component 100. The cooperation of the three can greatly reduce the probability of secondary leakage, reduce the maintenance cost, and has good economic and social benefits.
[0031] The plugging component 200 includes a foundation pit body 201a, a floor surface layer 201b, and a water stop strip 201c. The floor surface layer 201b is fixed on the top of the foundation pit body 201a. A water diversion groove X is opened on the top of the floor surface layer 201b. The water stop strip 201c is inserted into the inner wall of the foundation pit body 201a.
[0032] The foundation pit body 201a meets the characteristics of the part. Considering the structural conditions on both sides of the floor surface layer 201b, the post-cast concrete adopts a T-shaped structure bridging form to achieve reasonable load transfer and improve its anti-deformation ability. The number of the water diversion grooves X is two, which are respectively arranged on both sides of the top of the foundation pit body 201a. The water diversion grooves X can guide the water on the road surface to the ground to prevent water from leaking into the basement. The number of the water stop strips 201c is four, all of which are inserted into the inner wall of the foundation pit body 201a. When the water stop strip 201c is inserted into the inner wall of the foundation pit body 201a, it can closely fit the surrounding structure and effectively prevent water from penetrating through the gap between the foundation pit body 201a and the surrounding contact surface.
[0033] The sealing component 300 is arranged on the foundation pit body 201a and includes a sealing ring 301a, a pressing plate 301b, and a threaded rod 301c. The sealing ring 301a is located inside the foundation pit body 201a. The pressing plate 301b is arranged above the sealing ring 301a. The threaded rod 301c is inserted into the bottom of the pressing plate 301b, and the threaded rod 301c is threadedly connected with the pressing plate 301b.
[0034] After pouring concrete into the foundation pit body 201a, the sealing ring 301a is extruded to expand it outside the water diversion pipe 101, so as to prevent subsequent water leakage at the junction of the water diversion pipe 101 and the concrete. By rotating the extrusion plate 301b, the extrusion plate 301b can move on the threaded rod 301c, so that the extrusion plate 301b can extrude the sealing ring 301a to make it expand.
[0035] Embodiment 2
[0036] Refer to Figures 2 to 6 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.
[0037] Specifically, two reinforcing plates 202a are fixed in the foundation pit body 201a, and both are fixed on the inner wall of the foundation pit body 201a.
[0038] The reinforcing plate 202a has a high tensile strength and can withstand the tensile stress generated during the curing process of the concrete and during subsequent use. By arranging the reinforcing plate 202a in the foundation pit body 201a, the overall bearing capacity of the leak stoppage structure can be greatly enhanced, and the leak stoppage structure can be prevented from being damaged due to water pressure or other external forces.
[0039] Specifically, a rubber buffer belt 202b is fixed on the top of the bottom plate surface layer 201b, and the rubber buffer belt 202b is arranged on the top of the water diversion trough X.
[0040] The number of the rubber buffer belts 202b is two, and both are arranged on the top of the two water diversion troughs X. During the use of the water diversion trough X, there may be water flow impact, object dropping or other external forces. The rubber buffer belt 202b can play a buffering role and reduce the damage of these impacts to the top structure of the water diversion trough X.
[0041] Specifically, a steel nail 202c is inserted into one side of the water stop strip 201c, and the steel nail 202c is threadedly connected with the water stop strip 201c.
[0042] The steel nail 202c is inserted into the inner wall of the foundation pit body 201a, and the steel nail 202c is threadedly connected with the foundation pit body 201a. By arranging the steel nail 202c, the water stop strip 201c can be fixed on the inner wall of the foundation pit body 201a to prevent the water stop strip 201c from falling off.
[0043] Specifically, a leakage trough Y is arranged on one side of the foundation pit body 201a, and a floor slab 202d is arranged at the bottom of the leakage trough Y.
[0044] The number of the leakage troughs Y is two, which are respectively arranged on both sides of the top of the foundation pit body 201a. Through the arrangement of the leakage troughs Y, the form of concrete bridging is completed to realize the reasonable transfer of loads and improve its anti-deformation ability. The floor slab 202d is used to support the leakage troughs.
[0045] Specifically, a positioning plate 302a is fixed to the bottom of the threaded rod 301c, a threaded sleeve 302b is fixed to the top of the pressing plate 301b, and a turntable 302h is fixed to the top of the threaded sleeve 302b.
[0046] The positioning plate 302a is fixed to the inner wall of the water diversion pipe 101. The threaded sleeve 302b can be supported through the arrangement of the positioning plate 302a to prevent the threaded sleeve 302b from shifting. The arrangement of the turntable 302h facilitates the user to rotate the threaded sleeve 302b. By rotating the threaded sleeve 302b, the pressing plate 301b can be driven to rotate.
[0047] Specifically, a bevel block 302c is arranged on one side of the threaded sleeve 302b. The bevel block 302c is hinged to the threaded sleeve 302b, and a clamping block 302d is arranged on one side of the bevel block 302c.
[0048] The clamping block 302d is arranged as a bevel. When the threaded sleeve 302b moves during rotation, the bevel of the clamping block 302d will squeeze the bevel block 302c to make the bevel block 302c move. When the threaded sleeve 302b rotates in reverse to drive the bevel block 302c to move in the reverse direction, the clamping block 302d can limit the bevel block 302c to prevent the threaded sleeve 302b from rotating in reverse.
[0049] Embodiment 3
[0050] Refer to Figures 1 to 6 , which is the third embodiment of the present utility model. This embodiment is based on the first two embodiments.
[0051] Specifically, a support shaft 302e is inserted into one side of the bevel block 302c. The support shaft 302e is rotatably connected to the inner wall of the threaded sleeve 302b through a rotating shaft.
[0052] The support shaft 302e is used to support the bevel block 302c to prevent the bevel block 302c from shifting during movement.
[0053] Specifically, a torsion spring 302f is fixed to the bottom of the bevel block 302c. The torsion spring 302f is fixed to the inner wall of the threaded sleeve 302b.
[0054] When the bevel block 302c moves, it can apply a torsional force to the torsion spring 302f. When the bevel block 302c is separated from the clamping block 302d, the return force of the torsion spring 302f can drive the bevel block 302c to return to its original position.
[0055] Specifically, it further includes a main body assembly 100, which is arranged in the foundation pit body 201a and includes a water diversion pipe 101. The water diversion pipe 101 is inserted into the foundation pit body 201a.
[0056] By inserting the water diversion pipe 101 into the foundation pit body 201a, an external water pump can be connected to drain the accumulated water in the foundation pit body 201a, so as to subsequently pour concrete into it. After the pouring is completed, the redundant water diversion pipe 101 is cut off, thus completing the construction.
[0057] During use, all the original floor slabs in the passage part are chiseled off to chisel out the foundation pit body 201a required for leak stoppage. Two notches are chiseled on the concrete joint surface of the floor slab surface layer 201b for installing the water stop strip 201c. The water stop strip 201c is installed on the inner wall of the foundation pit body 201a through the steel nails 202c. Steel bars are tied to form a steel bar plate 202a and laid in the foundation pit body 201a. One water diversion pipe 101 is inserted at each of the two long ends of the floor slab surface layer 201b, facilitating subsequent pouring.
[0058] By rotating the turntable 302h, the turntable 302h drives the threaded sleeve 302b to rotate. When the threaded sleeve 302b rotates, it can drive the pressing plate 301b to move on the threaded rod 301c. By moving the pressing plate 301b to the top of the sealing ring 301a and pressing it, the sealing ring 301a expands. When the threaded sleeve 302b moves in rotation, the inclined surface of the block 302d presses the inclined surface block 302c to make the inclined surface block 302c move. When the inclined surface block 302c moves, it can apply a torsional force to the torsion spring 302f. When the inclined surface block 302c is separated from the block 302d, the inclined surface block 302c can be driven back to its original position by the return force of the torsion spring 302f. When the threaded sleeve 302b is rotated in reverse to drive the inclined surface block 302c to move in the reverse direction, the block 302d can limit the inclined surface block 302c to prevent the threaded sleeve 302b from rotating in reverse. At this time, the water diversion pipe 101 is closed. Then, concrete is poured into the foundation pit body 201a. After the construction is completed, the redundant water diversion pipe 101 is cut off. Finally, a water diversion groove X is opened on the floor slab surface layer 201b, and a rubber buffer belt 202b is arranged at the top of the water diversion groove X, thus completing the construction of the bridging structure.
[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
