[0002] Plastic steel sheet pile is a new type of building material, which is formed by extruding a mixture of polymer reinforced composite materials and a variety of additives. It is currently being used more and more widely in engineering construction fields such as river bank protection, foundation pit support and anti-seepage.

[0003] In the existing construction method of plastic-steel sheet piles, woodworking clamps are often used to clamp the sheet pile joints on both sides of the plastic-steel sheet piles and the delivery piles (steel sheet piles), and a woodworking clamp is installed every two meters on one side. It should be noted that, in general, 6 meters of plastic-steel sheet piles need to be equipped with 4 woodworking clamps, and it takes a certain amount of time to clamp and install. The woodworking clamp clamps the plastic-steel sheet piles and the delivery piles (steel sheet piles) by screwing in the threads. The vibration of the vibrating pile hammer during construction will loosen the screw of the woodworking clamp, causing a gap between the plastic-steel sheet piles and the delivery piles (steel sheet piles), and dirt and other debris will enter.

For example, after each injection and extraction, the surface of the delivery pile (steel sheet pile) must be cleaned again, which makes the construction more complicated. In addition, if the plastic-steel sheet pile and the delivery pile (steel sheet pile) are not clamped, there is a risk of breaking the plastic-steel sheet pile. The existing clamping structure cannot be effectively adjusted according to the specifications of the plastic-steel sheet pile, and its applicability is poor. Utility Model Content
