In the above-mentioned soil pressure control precast pile superposed sheet pile seam sealing structure, the above-mentioned slot is a hollow structure formed by splicing grooves formed by bending outer group steel plates.
The utility model discloses an earth pressure control precast pile coincide sheet pile seam stagnant water structure can utilize the earth pressure who acts on outer group's steel sheet, control slot and the construction deviation of inserting between the falcon, and the quality is reliable, and the cost is low, and the construction is quick, and the stagnant water is effectual.
Drawings
Fig. 1 is a schematic cross-sectional structure diagram of a soil pressure control precast pile composite sheet pile seam water stop structure used in an embodiment of the present invention.
Detailed Description
As an embodiment of the present invention, the structure and the operation principle of the composite sheet pile seam water stop structure for soil pressure control precast pile according to the present invention are described below with reference to fig. 1. This kind of soil pressure control precast pile coincide sheet pile seam stagnant water structure includes the steel sheet that three group superpositions were placed and two parts in succession of steel sheet at least, and wherein the steel sheet that three group superpositions were placed is laid along precast pile axis direction to set up in adjacent stake seam position of precast pile, this kind of stagnant water structure cross section picture is shown as figure 1, on along precast pile (1) pile length, can with length setting such as precast pile (1), also can be shorter than precast pile (1), satisfy the stagnant water and go into native degree of depth requirement can. In this embodiment, the precast pile (1) may be a steel pipe pile, an H-shaped steel pile, a PHC pipe pile, a steel sheet pile, or a precast reinforced concrete square pile of various cross sections, which is a long steel structure or a reinforced concrete structure precast member sunk into the soil. The middle group of steel plates (2) are positioned between the two groups of outer group of steel plates (4), the middle group of steel plates (2) are connected with one precast pile (1) in the adjacent precast piles (1) through steel plate connections (6), and the two groups of outer group of steel plates (4) positioned on two sides are connected with the other precast pile (1) in the adjacent precast pile through the steel plate connections (6). In this embodiment, the steel plate connection (6) may be welding, or may be other types of connection such as bolt connection and embedded connection. Connect on well group's steel sheet (2) and insert falcon (3), insert falcon (3) and be greater than the component of well group's steel sheet (2) thickness for cross sectional dimension, in this embodiment, can adopt the round steel preparation, can with the round steel beading in the one side of group's steel sheet (2) can. Set up slot (5) between two sets of outer group steel sheet (4), slot (5) are the cross sectional dimension and are greater than the cavity in clearance between two sets of outer group steel sheet (4), insert falcon (3) and slot (5) and all arrange along precast pile (1) axis direction, insert falcon (3) and insert in slot (5). In this embodiment, the slot (5) may be a hollow structure formed by splicing grooves formed by bending the outer steel plates (4), as shown in fig. 1. In the embodiment, the two groups of outer steel plates (4) bear the soil pressure acting on the contact surface position of the outer steel plates (4) and the soil body in the pile sinking construction process of the precast pile (1).
This patent includes, but is not limited to, other similar structures that may be substituted by one skilled in the art.
