Description

Technical Field

[0001] The utility model relates to the technical field of steel sheet pile driving, in particular to a steel sheet pile driving auxiliary device. Background Art

[0002] Steel sheet piles are a type of steel structure with linkage devices on the edges, which can be freely combined to form a continuous and tight retaining wall or water retaining wall. Steel sheet piles are a type of steel with a locking mouth. Their cross-sections include straight plate, groove and Z-shaped, and come in various sizes and interlocking forms. Common types include Larsen type and Lackawanna type. Their advantages are: high strength and easy to drive into hard soil layers; they can be constructed in deep water and, if necessary, added with inclined supports to form a cage; they have good waterproof performance; they can be formed into cofferdams of various shapes as needed and can be reused many times. Therefore, they have a wide range of uses.

[0003] In the prior art, the inventors found that there are at least the following problems in the prior art:

[0004] (1) When sinking steel sheet piles, due to their inherent flexibility, the sheet piles cannot be driven into the ground smoothly during construction. In addition, there are often hard plastic soil layers or even hard soil layers within the support depth to increase the thrust on them. However, the unstable force applied may cause the steel sheet piles to bend, which can easily cause damage to the sheet piles.

[0005] (2) When sinking steel sheet piles, the steel sheet piles need to be hoisted and then pressed down. When fixing the steel sheet piles, the top of the steel sheet piles are usually clamped and pressed down from the top of the steel sheet piles, which can easily lead to uneven force on the steel sheet piles and inconvenience in operation. Utility Model Content

[0006] In response to the shortcomings of the existing technology, the utility model provides a steel sheet pile driving auxiliary device, which has the advantages of facilitating the guidance and limitation of the steel sheet piles being driven, effectively preventing the steel sheet piles from bending, and solving the uneven force when pressing the steel sheet piles downward, thereby solving the problems raised in the background technology.

[0007] The utility model provides the following technical solutions: a steel sheet pile sinking auxiliary device, comprising a crossbeam, a steel sheet pile is arranged inside the crossbeam, an auxiliary top plate is provided at the top of the steel sheet pile, a movable seat is slidably clamped on the surface of the crossbeam, an electric telescopic rod is fixedly connected to the top of the movable seat, one end of the electric telescopic rod is fixedly connected to a fixed guide block, a sliding rod is slidably inserted on the surface of the fixed guide block, one end of the sliding rod is fixedly connected to an abutment block, and a plurality of rollers are rotatably connected to the side of the abutment block, and the rollers are located on one side of the steel sheet pile.

[0008] Preferably, both ends of the movable seat are threadedly connected with locking bolts, and the ends of the locking bolts abut against the side surfaces of the beam.

[0009] Preferably, a fixed block is fixedly connected to the lower surface of the movable seat, a threaded rod 1 is threadedly inserted into the side surface of the fixed block, one end of the threaded rod 1 is rotatably connected to a clamping seat, and the clamping seat matches the model and specifications of the edge of the steel sheet pile.

[0010] Preferably, the side surface of the fixed guide block is threadedly connected to a second threaded rod, and one end of the second threaded rod is rotatably connected to the side surface of the abutment block.

[0011] Preferably, a fixing head is fixedly connected to the side surface of the abutment block, one end of the fixing head is threadedly connected to an abutment screw, and one end of the abutment screw abuts against the inner wall of the beam.

[0012] Preferably, a fixing plate is fixedly connected to the lower surface of the auxiliary top plate, an electric telescopic rod 2 is fixedly connected to the lower surface of the auxiliary top plate, one end of the electric telescopic rod 2 is fixedly connected to an abutment plate, the abutment plate abuts against one side surface of the top of the steel sheet pile, and the fixing plate abuts against the other side surface of the top of the steel sheet pile.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The cam is fixed on the upper edge of the two beams and the upper edge of the two beams is fixed on the lower edge of the two beams, and the sliding seat is moved to the position on the surface of the beam. When it moves to the specified position, the locking bolt is tightened to fix the position of the moving seat, and the threaded rod is rotated to adjust the position of the clamping seat so that the clamping seat is engaged with the edge of the steel sheet pile. Then, the electric telescopic rod is started to move the fixed guide block to one side of the steel sheet pile. The threaded rod is manually rotated to drive the abutment block to move so that the side of the roller on the side of the abutment block abuts the side wall of the steel sheet pile. Finally, the abutment screw is manually rotated so that one end of the abutment screw abuts the inner wall of the beam to fix the position of the abutment block. When the steel sheet pile is sunk, the clamping seat is limited to the edge of the steel sheet pile by sliding and clamping, and the roller limits the moving steel sheet pile, which effectively ensures that the steel sheet pile does not bend during the sinking process, thereby making the pile sinking operation smoother and avoiding damage to the steel sheet pile.

[0015] 2. By providing an auxiliary top plate, when lifting the steel sheet pile, the auxiliary top plate is abutted against the top of the steel sheet pile. At this time, one side of the top of the steel sheet pile is abutted against the side of the fixed plate, and the electric telescopic rod 2 is started to drive the abutting plate to move, so that the abutting plate and the fixed plate cooperate with each other, thereby clamping and fixing the top of the steel sheet pile. In the process of pile sinking, since the lower surface of the auxiliary top plate fits with the top of the steel sheet pile, the contact area with the steel sheet pile during the downward pressing process of the steel sheet pile is greatly increased, thereby ensuring the uniformity of the force on the steel sheet pile and improving the pile sinking efficiency of the steel sheet pile.

[0023] Among them, the lower surface of the movable seat 3 is fixedly connected with a fixed block 5, and a threaded rod 6 is threadedly inserted into the side of the fixed block 5. One end of the threaded rod 6 is rotatably connected to a clamping seat 7. The clamping seat 7 matches the model and specifications of the edge of the steel sheet pile 2. After rotating the threaded rod 6, the position of the clamping seat 7 is adjusted so that the clamping seat 7 is clamped with the edge of the steel sheet pile 2.
