Description

TECHNICAL FIELD

[0001] The utility model relates to the field of hydraulic engineering, concretely relates to a sluice bottom plate anti -seepage structure. BACKGROUND

[0002] The sluice is a kind of low water head hydraulic structure using gate to retain water and discharge water. After the completion of the sluice, seepage will be generated under the sluice foundation under the action of the head difference between upstream and downstream, which will adversely affect the sluice and even cause safety accidents. Good anti-seepage design of the sluice foundation is crucial to ensure the safety of the sluice.

[0003] Cement-soil mixing pile is widely used as vertical anti-seepage body of sluice due to its convenient construction, reliable technology and economic rationality, and can also be used as water-stopping and enclosing pile for foundation pit construction, and has strong applicability to different geological conditions. However, the connection between the cement-soil mixing pile anti-seepage wall and the sluice bottom plate is unreliable, which often forms a weak link of seepage, resulting in poor anti-seepage effect.

[0004] The traditional connection method directly embeds the cement-soil mixing pile into the bottom plate. The stiffness of the cement-soil mixing pile anti-seepage body is much lower than that of the upper bottom plate. When uneven settlement occurs in the bottom plate, the upper part of the anti-seepage body is easily damaged, and the lateral stiffness of the anti-seepage body is low. When the horizontal force transmitted by the bottom plate is received, shear failure easily occurs at the top of the anti-seepage body. TECHNICAL SOLUTION

[0005] Based on the above description, the utility model provides a sluice bottom plate anti-seepage structure to solve the problem of unreliable connection between the existing cement-soil mixing pile anti-seepage body and the sluice bottom plate and poor anti-seepage effect.

[0006] The technical solution of the utility model to solve the above technical problem is as follows:

[0007] A sluice bottom plate anti-seepage structure, characterized by comprising:

[0008] A protruding block is arranged on the lower side of the sluice bottom plate.

[0009] A mixing pile extends along the up-down direction and is arranged below and opposite to the protruding block to form a gap between the lower end surface of the protruding block and the upper end surface of the mixing pile.

[0010] A connecting structure comprises a rubber waterstop and at least two sealing plates. The thickness direction of the rubber waterstop is adapted to the distribution direction of the upstream and downstream, and the length of the rubber waterstop is adapted to the length of the protruding block. The rubber waterstop is arranged in the gap, and its two sides distributed along the up-down direction are embedded into the mixing pile and the protruding block respectively. The two sealing plates are attached to the two sides of the rubber waterstop along the thickness direction to seal the gap.

[0011] On the basis of the above technical solutions, the utility model further can make improvement as follows:

[0012] Further, the connecting structure further comprises a sealing layer, and the sealing layer wraps the outer periphery of the two sealing plates.

[0013] Further, the sealing layer is a low-modulus sealing glue layer.

[0014] Further, the mixing pile comprises a pile body extending in the up-down direction and a pile cap connected to the upper end of the pile body.

[0015] At least part of the rubber waterstop is embedded in the pile cap.

[0016] Further, the mixing pile further comprises a reinforcing bar, and the reinforcing bar is arranged in the pile body and the pile cap.

[0017] Further, the two sides of the rubber waterstop distributed in the up-down direction are connected to the protruding block and the middle of the mixing pile respectively.

[0018] Further, the sealing plate is a low-foaming polyethylene foam plate.

[0019] Compared with the prior art, the technical scheme of the application has the following beneficial technical effects:

[0020] The thickness of the rubber waterstop is adapted to the distribution direction of the upstream and downstream, the two sides of the rubber waterstop in the up-down direction are embedded in the protruding block and the mixing pile respectively, and the length of the rubber waterstop is adapted to the protruding block, so as to realize water stopping and flexible connection of the sluice bottom plate and the mixing pile. The two sealing plates are attached to the two sides of the rubber waterstop in the thickness direction, for sealing the gap and supporting the part of the rubber waterstop located in the gap. In addition, the protruding block is connected to the rubber waterstop, avoiding the destruction of the reinforcing steel bars in the lower part of the sluice bottom plate caused by the direct connection of the rubber waterstop to the sluice bottom plate. In this way, the gap is completely sealed, has good water stopping and anti-seepage effect, and the flexible connection can withstand the horizontal force transmitted by the uneven settlement of the sluice bottom plate, preventing the shear failure of the upper end of the mixing pile.
