What is the tenon of reinforced concrete sheet pile?
Reinforced concrete sheet pile mortise: It is the protruding part of the joint of the component using the concave-convex method.
Among the reinforced concrete sheet piles, there are many hollow sheet piles. The hollow is mostly circular, and the steel pipe is used as the core mold. The mortise of the sheet pile is generally round and better. The general slope of the pile tip is 1:2.5～1:1.5.
The special structure and specific use of reinforced concrete sheet piles can be designed and manufactured according to the needs, and the groove and tenon structure can solve the joint waterproofing. It is required to ensure that the pile top of the sheet pile wall is on a design horizontal plane and the axis of the sheet pile wall On a straight line, the tongue and groove are straight and the position is accurate.
1. The concrete of the pile body should be poured at one time, and no construction joints should be left.
2. There shall be no regular cracks on the concrete surface at the steel hoop position.
3. The tenon of the sheet pile must not have defects such as missing corners and damage.
4. The strength of the prefabricated sheet pile when hoisting should be greater than 70% of the design strength.
5. The deviation of the position of the lifting point should not exceed, and the angle between the sling and the axis of the pile body should not be less than 45°.
6. When stacking sheet piles, attention should be paid to: using multiple pads, and the pads are laid evenly; each layer of pads stacked in multiple layers should be on the same vertical line; stacking on site does not exceed 3 layers, and stacking in the factory does not exceed 7 layers. layer.
7. Attention should be paid when sheet piles are shipped: draw the pile installation diagram according to the pile sinking sequence, and load the ship and vehicle according to the diagram; during transportation, use wooden wedges to cushion the pads, and take appropriate reinforcement measures according to the actual situation; Shipment with fewer stacks.

What is the penetration depth of sheet piles?
Answer: It is the anchoring length of the sheet pile in the ground.

What is sheet pile drainage?
Water wells are of great significance to the development of human civilization. Before the appearance of water wells, human beings lived by the water and could only live in places with surface water or springs. The invention of water wells expanded the scope of human activities. China is one of the earliest countries in the world to develop and utilize groundwater. The earliest well discovered in China is the well at the Hemudu ancient cultural site in Yuyao, Zhejiang, and its age is about 1000 years ago. This is a rather delicate square wooden well with a depth of 1.35 meters and a side length of 2 meters. It can be inferred from this that the appearance of primitive wells was much earlier.
