File foundation-flexile reinforcement cushion layer composite bearing table type sheet-pile structure

Abstract

The invention discloses a tile foundation-flexile reinforcement cushion layer composite bearing table type sheet-pile structure. The file foundation-flexile reinforcement cushion layer composite bearing table type sheet-pile structure comprises a front sheet-pile wall, an anchorage wall, a connection pull rod used for connecting the front sheet-pile wall with the anchorage wall, and a bearing table located between the front sheet-pile wall and the anchorage wall, and is mainly characterized in that the bearing table comprises a granular mixture reinforcement cushion layer and pile foundations, the granular mixture reinforcement cushion layer is composed of a granular mixture material laying layer and geosynthetics reinforcing ribs embedded in the granular mixture material laying layer, and at least two rows of pile foundations are located below the granular mixture reinforcement cushion layer and support the granular mixture reinforcement cushion layer. The tile foundation-flexile reinforcement cushion layer composite bearing table type sheet-pile structure is easy to construct, capable of saving materials, balanced in load stress, firm and durable in structure, and suitable for constructing large-tonnage, large-scale and deep water type wharfs.

Description

technical field [0001] The invention relates to building structures in the fields of port engineering, water conservancy engineering, etc., in particular to a pile foundation-flexible reinforced cushion composite cap-type sheet pile structure suitable for sheet pile retaining structures such as deep-water port wharfs and bank revetments. Background technique [0002] Sheet pile structure is one of the three types of wharf structure, which has the characteristics of fast construction speed, short construction period and low cost, and is widely used in our country. The sheet pile wharf consists of a front sheet pile wall, an anchorage wall and tie rods, and mainly relies on the front sheet pile wall to bear the earth pressure generated by different soil heights on both sides of the water and land. Due to the limitation of the section size of the front sheet pile wall, most of the current sheet pile piers are small and medium-sized piers. With the development of our country's...

Problems solved by technology

The disadvantages of this method are: first, the amount of engineering materials is large, the construction is complicated, and the construction period is long; second, the concrete cap is a rigid structure, and the joints connected with the pile foundation need special treatment

Due to the complexity of soil properties, uneven settlement of the foundation often occurs, and stress concentration tends to occur near the joints of piles and caps, resulting in cracking or damage due to excessive internal force of the structure

In addition, due to the large difference in stiffness between the concrete cap and the pile body in the horizontal direction, when subjected to large additional horizontal loads such as earthquakes, it is often easy to cause the top of the pile to fail first, resulting in the overall failure of the structure
