Description

TECHNICAL FIELD

[0001] The present application relates to the civil engineering technical field, especially to a PC method combined pile shearing waterproof device. BACKGROUND

[0002] In the current PC method pile system, the steel pipe pile and the surrounding purlin are connected in a natural way, the steel sheet pile and the steel pipe pile are connected in a tongue and groove connection, and the steel sheet pile is not connected with the surrounding purlin, which has the following problems:

[0003] Firstly, the vertical shearing capacity of the connection between the fender pile and the surrounding purlin is weak. The contact area between the round shape of the steel pipe pile and the surrounding purlin is small, resulting in weak vertical shearing capacity of the connection between the fender pile and the surrounding purlin; if an inclined support structure is arranged in the pit, the surrounding purlin will be lifted, and even the surrounding purlin and the fender pile will be separated, which is not conducive to the safety of the foundation pit.

[0004] Secondly, the waterproofing of the connection between the steel sheet pile and the surrounding purlin is weak. At present, considering the need for the surrounding purlin steel reinforcement to be connected, the steel sheet pile usually does not extend into the surrounding purlin, resulting in poor water stop effect between the surrounding purlin and the steel sheet pile, which is not conducive to the protection of the surrounding environment.

[0005] In addition, the current method of welding a steel plate or other shearing member on the steel pipe pile cannot solve the waterproofing problem, and will cause certain difficulties in the recycling of the steel pipe pile. SUMMARY

[0006] The purpose of the present application is to overcome the defects of the prior art and provide a PC method combined pile shearing waterproof device.

[0007] The purpose of the present application can be achieved by the following technical solutions:

[0008] A PC method combined pile shearing waterproof device, comprising two steel pipe piles, a steel sheet pile, a shearing member for improving the shearing capacity of the steel pipe pile, and a water stop member for improving the waterproofing capacity of the steel sheet pile, the steel pipe piles and the steel sheet pile are vertically arranged, the two ends of the steel sheet pile are fixedly connected with the side surfaces of the two steel pipe piles, the shearing member is arranged on the top end of the steel pipe pile, and the water stop member is arranged on one side of the steel sheet pile.

[0009] Preferably, the shearing member comprises two hoops matched with the shape of the steel pipe pile and a plurality of shearing pieces, the hoops are sleeved on the top end of the steel pipe pile, and the shearing pieces are fixedly arranged on the side surface of the hoops.

[0010] Preferably, the shearing pieces are steel reinforcement pieces or steel plate pieces.

[0011] Preferably, the shearing pieces are fixedly connected with the hoops by welding.

[0012] Preferably, the hoop comprises a plurality of hoop segments and hoop connectors, the hoop segments are fixedly connected through the hoop connectors, and the hoop segments are sequentially connected head to tail to form the hoop.

[0013] Preferably, the hoop comprises two half-ring hoop segments.

[0014] Preferably, the water stop member comprises a connecting plate and a water stop plate, two ends of the connecting plate are fixedly connected with two hoops respectively, the connecting plate is arranged parallel to the side surface of the steel sheet pile, the top end of one side surface of the water stop plate is fixedly connected with the side surface of the connecting plate, and the bottom end of the other side surface of the water stop plate is attached to the top end of the steel sheet pile.

[0015] Preferably, the two ends of the connecting plate are provided with first through holes, the top end of the water stop plate is provided with a second through hole corresponding to the first through hole of the connecting plate, the side surface of the hoop is provided with a connecting hole, and the water stop member further comprises a bolt and a nut, the bolt is sequentially threaded through the connecting hole, the first through hole and the second through hole, and then screwed with the nut.

[0016] Preferably, the water stop plate is a polymer modified asphalt plate.

[0017] Preferably, the side surface of the steel pipe pile is provided with a connecting groove, and the end portion of the steel sheet pile is fixedly connected with the steel pipe pile through the connecting groove.

[0018] Compared with the prior art, the present application has the following advantages:

[0019] (1) The connection between the pile and the surrounding purlin is more reliable: when the top end of the steel pipe pile is provided with the surrounding purlin, the shear force received by the surrounding purlin is borne by the hoop and the shear member around the side surface of the hoop, so that the vertical shear stress at the connection between the steel pipe pile and the surrounding purlin is more reliable, and the safety of the foundation pit engineering is high.

[0020] (2) The connection between the steel sheet pile and the surrounding purlin is more reliable: the water stop member of the present application effectively solves the problem that the steel sheet pile does not usually extend into the surrounding purlin, resulting in poor water stop effect between the surrounding purlin and the steel sheet pile, and the water stop plate is arranged by the connecting member, which effectively blocks the space between the steel sheet pile and the surrounding purlin, so that the water stop is more reliable and more conducive to the protection of the environment around the foundation pit.

[0021] (3) Better construction convenience, higher construction efficiency and better economy: the joint form of the present application does not need to use welding or other forms to connect the shear member and the enclosing pile, so that the construction efficiency is high and the construction convenience is good; in the process of recycling the steel pipe pile, the components can be recycled at the same time, which is good in economy.
