Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further explained below by combining the specific drawings.
The improved generation wharf integrated configuration that this example provided has replaced conventional sheet pile pier, has solved the problem that sheet pile pier horizontal rigidity is little and the displacement is big, has good result of use to using large-scale sheet pile pier on the soft soil foundation, and has characteristics such as engineering cost is low, construction speed is fast, construction is simple and convenient.
This example provides an improved generation wharf integrated configuration, includes: sheet pile wharf structure and low pile cap structure, wherein, low pile cap structure sets up at the trailing edge of sheet pile wharf structure, and such structure sets up for the cushion cap has the off-load effect, and soil pressure effect behind the reducible sheet pile wall.
As shown in fig. 1 and 2, the pile structure of the present sheet pile comprises: the cast-in-place diaphragm wall comprises a cast-in-place diaphragm wall 1, a cast-in-place breast wall 2, a steel pull rod 3, a cap beam 4 and an anchorage pile 5.
The cast-in-place diaphragm wall 1 is continuously arranged in the direction parallel to the line 9 in front of the wharf, the cast-in-place breast wall 2 and the cast-in-place diaphragm wall 1 are connected into a whole, the anchor pile 5 is located behind the cast-in-place diaphragm wall 1 and is connected through the steel pull rod 3, and the slab pile wall can be guaranteed to be stable in skirting.
The cast-in-place diaphragm wall 1 is continuously arranged, a reinforced concrete structure is adopted, structural seams are arranged among structural sections, the structure arrangement enables the cast-in-place diaphragm wall 1 to be high in rigidity, and the sectional arrangement enables the cast-in-place diaphragm wall 1 to overcome uneven settlement.
In the concrete implementation, the cast-in-place underground diaphragm wall 1 is of a cast-in-place reinforced concrete structure and is cast in place in sections.
