Description
Technical Field
[0001] The present application relates to the technical field of underground pouring, and in particular to a quick-release joint device for preventing the upward return of poured underground concrete. Background Art
[0002] In underground engineering, it is often necessary to pour concrete into the soil body to fill the cracks and cavities in the soil body, thereby improving the bearing capacity of the foundation. In the existing related technologies, the concrete is mainly poured and filled into the pouring holes in the soil body through a pump truck, a pouring hose and a pouring conduit. Specifically, the pump truck is used to store and pump the concrete. The two ends of the pouring hose are respectively flange-connected to the pump truck and the pouring conduit, and the pouring conduit is located in the pouring hole. The pump truck transports the concrete to the pouring hole through the pouring hose and the pouring conduit, and fills the pouring hole and the crack cavities communicating with the pouring hole, so that the foundation has a greater bearing capacity after the concrete is formed.
[0003] In view of the above related technologies, when the pump truck stops pumping the concrete, there is a situation where the concrete returns upward under the action of soil pressure, causing the concrete to flow reversely from the soil cracks and cavities into the pouring hose, affecting the pouring quality of the concrete and being unfavorable for ensuring the bearing capacity of the foundation. Summary of the Invention
[0004] In order to reduce the occurrence of the upward return of the concrete, the present application provides a quick-release joint device for preventing the upward return of poured underground concrete.
[0005] The quick-release joint device for preventing the upward return of poured underground concrete provided by the present application adopts the following technical solutions:

[0007] The one-way valve member includes a connecting pipe body, a hollowed-out sliding ring, a check block, a check ring and a support ring. A connecting cavity is formed in the connecting pipe body, and the connecting cavity is vertically penetrated. The hollowed-out sliding ring is slidably fitted in the connecting cavity in the vertical direction, and the check block is installed on the hollowed-out sliding ring;
[0008] The top of the check block is provided with an active check inclined surface, and the active check inclined surface is arranged downward and toward the inner wall of the connecting cavity; the check ring is installed on the connecting pipe body and is located in the connecting cavity, and the bottom of the check ring is provided with a passive check inclined surface, and the passive check inclined surface is arranged downward and toward the inner wall of the connecting cavity;

[0013] By adopting the above technical solution, when the concrete returns upward and contacts the bottom of the check block, it is convenient for the concrete to be concentrated in the check water groove first, and then quickly overcome the gravity of the check block to push the check block, so that the active check slope contacts the passive check slope, thereby quickly closing the connecting cavity.
[0014] Optionally, a bottom guiding slope is provided at the bottom of the support ring, and the bottom guiding slope is arranged downward from top to bottom towards the inner wall of the connecting cavity.
[0015] By adopting the above technical solution, when the concrete returns upward, it is convenient for the bottom guiding slope to guide the concrete to be concentrated in the check water groove first, and then quickly overcome the gravity of the check block to push the check block, so that the active check slope contacts the passive check slope, thereby quickly closing the connecting cavity.
[0016] Optionally, a top guiding slope is provided at the top of the support ring, and the top guiding slope is arranged downward from top to bottom towards the axis of the connecting cavity.
[0017] By adopting the above technical solution, it is convenient to reduce the resistance of the support ring to the normal conveyance of the concrete (i.e., when there is no return), and reduce the occurrence of blockage of the connecting cavity.
[0018] Optionally, the check block includes a check seat body and an active check body. The check seat body is installed on the hollow sliding ring, the active check body is installed on the top of the check seat body, the active check slope is arranged on the top of the active check body, and the active check body has elasticity.
[0019] By adopting the above technical solution, the elastic active check body is more likely to ensure that there is no gap between the active check body and the check ring after contacting the check ring, thereby reducing...
[0020] Optionally, the check block includes a check seat body and an active check body. The check seat body is installed on the hollow slip ring. The active check body is vertically movably fitted to the top of the check seat body, and the active check inclined surface is arranged at the top of the active check body.
[0021] By adopting the above technical solution, it is convenient to adjust the distance between the active check body and the check ring according to the pumping pressure of the concrete pump truck and the upward return pressure of the concrete, so as to ensure both the conveying speed of the concrete and the cut-off speed of the upward return of the concrete.
[0022] Optionally, the connecting pipe body is detachably fitted to the top connecting pipe and / or the bottom connecting pipe.
[0023] By adopting the above technical solution, it is convenient to remove and maintain the one-way valve member.
[0024] Optionally, the top connecting pipe is rotatably fitted with a top lock. The top lock is elastic. A top lock groove is formed on the outer wall of the connecting pipe body, and the top lock is snap-fitted to the top lock groove;

[0026] By adopting the above technical solution, by rotating the top lock to make the top lock snap-fitted to the top lock groove, or by separating the top lock from the top lock groove, the disassembly and assembly of the top connecting pipe can be quickly completed, which is beneficial to improving the concrete pouring efficiency.
[0027] Optionally, a top gasket is provided between the top connecting pipe and the connecting pipe body;
[0028] And / or, a bottom gasket is provided between the bottom connecting pipe and the connecting pipe body.
[0029] By adopting the above technical solution, it is beneficial to ensure the sealing performance between the top connecting pipe and the connecting pipe body.
[0030] In summary, the present application includes at least one of the following beneficial technical effects:
[0031] 1. The check block is naturally placed on the top of the support ring under the action of gravity. The concrete sequentially passes through the pouring hose, the top connecting pipe, the connecting pipe body, the bottom connecting pipe, and the pouring conduit, so as to convey the concrete into the pouring hole. When the concrete has an upward return, the concrete overcomes the gravity of the check block from the bottom of the connecting cavity, causing the check block to move upward in the direction close to the check ring, and then making the active check inclined surface contact the passive check inclined surface, thereby closing the connecting cavity and reducing the occurrence of the upward return of the concrete;
[0032] 2. When it is convenient to contact the bottom of the check block on the returned concrete, the concrete is first concentrated in the check water groove, and then quickly overcomes the gravity of the check block to push the check block, so that the active check inclined surface contacts the passive check inclined surface, thereby quickly connecting the cavity to be closed;
[0033] 3. When the concrete returns, it is convenient to guide the concrete to be concentrated in the check water groove first through the bottom guiding inclined surface, and then quickly overcome the gravity of the check block to push the check block, so that the active check inclined surface contacts the passive check inclined surface, thereby quickly connecting the cavity to be closed.
