Embodiment

[0033] A kind of sheet pile 5 pile sinking methods, such as Figure 1-4 As shown, the construction steps include:

[0034] ①Measuring and setting out: measure the position of the foundation 11, and determine the construction axis of the guide wall 2;

[0035] ②Construction of guide wall 2: according to the construction axis, guide wall 2 formworks on both sides are set up, concrete is poured and maintained;

[0036] ③ Excavation and trenching: use ground-to-wall trenching machine to excavate earthwork along the direction of guide wall 2, and use mud pump to pour wall protection slurry 3 into preformed trench 4 at the same time during the excavation process to form preformed trench 4 and form preformed trench 4. Check the position accuracy of the pre-groove 4 after the groove 4 is formed.

[0037] ④ Pile sinking of sheet pile 5: Lift the sheet pile 5 with a lifting device, align it with the construction axis and vertically put it into the preformed groove 4, and sink the pile...

Abstract

The invention discloses a sheet pile sinking method and a pile foundation trench and relates to the field of water conservancy projects. The construction method comprises the steps of (1) surveying and setting-out; (2) guide wall construction; (3) earth excavation and trench forming; (4) sheet pile driving; (5) sheet pile deviation rectifying; and (6) sheet pile sinking. The sheet pile sinking method has the advantages that operation is easy, the construction efficiency is high, the quality of sheet piles can be protected, and the construction difficulty is reduced.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a sheet pile sinking method and a pile foundation groove thereof. Background technique [0002] Reinforced concrete sheet piles have the advantages of high strength, high rigidity, convenient material acquisition and simple construction. However, due to the domestic limitation of hammering piles for a long time, and the capacity of hammering equipment is limited, the size and length of piles are greatly restricted, the applicable depth of foundation pits is limited, and the application prospect of reinforced concrete sheet piles is sluggish. [0003] For mass concrete sheet piles, the weight of a single concrete sheet pile is high, much heavier than conventional reinforced concrete sheet piles. The matching gap between the sheet piles is small, and the precision requirement is high. The existing hammer pile technology is difficult to meet the pile driving accuracy r...
