Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of pile foundation engineering of building structure system, especially to a reinforced concrete U-shaped sheet pile with longitudinal ribs. BACKGROUND

[0002] The U-shaped sheet pile is widely applied in the construction enclosure field of various buildings due to its good mechanical properties and manufacturing advantages, such as large underground buildings, slopes, tunnels, port wharf shores, and river embankments.

[0003] The strength performance of the U-shaped sheet pile directly affects the bearing capacity thereof when being used for retaining and enclosing. The existing concrete U-shaped sheet pile comprises a pile body, and the pile body is internally provided with main reinforcement and stirrups. The steel mesh or steel cage formed by the main reinforcement and the stirrups can effectively improve the stress strength of the U-shaped sheet pile. However, for the U-shaped sheet pile with a relatively long longitudinal length, the internal steel mesh or steel cage cannot guarantee the rigidity requirement of the pile body in the longitudinal direction, so that the U-shaped sheet pile lacks torsional rigidity in the longitudinal direction. Moreover, when the U-shaped sheet pile is being sunk, it may encounter a relatively hard stratum such as sand and gravel. If the wall thickness of the U-shaped sheet pile is increased to increase the longitudinal rigidity thereof or to avoid longitudinal cracks, the production cost of the U-shaped sheet pile will be greatly increased, which is not conducive to the popularization and application of the U-shaped sheet pile.

[0004] In summary, the existing U-shaped sheet pile has defects in guaranteeing the longitudinal rigidity thereof. SUMMARY

[0005] The utility model solves the technical problem of the existing U-shaped sheet pile by providing a reinforced concrete U-shaped sheet pile which can effectively improve the longitudinal rigidity thereof without significantly increasing the cost.

[0008] By adopting the above connection mode, the sealing property and stability of adjacent U-shaped sheet piles during connection can be ensured, and further, waterproof structures can be arranged in the grooves or convex structures to further improve the waterproof performance of the plurality of U-shaped sheet piles during connection and use.

[0009] As preferred, one or several longitudinal rib structures are arranged on the upper surface of the base plate, or one or several longitudinal rib structures are arranged on the lower surface of the base plate.

[0010] As preferred, one or several longitudinal rib structures are arranged on the inner surfaces of the two side plates respectively, or one or several longitudinal rib structures are arranged on the outer surfaces of the two side plates respectively.

[0011] As preferred, one or several longitudinal rib structures are arranged on the upper surfaces of the two flanges respectively, or one or several longitudinal rib structures are arranged on the lower surfaces of the two flanges respectively.

[0012] Further, one or several longitudinal rib structures can be symmetrically arranged on the base plate, the two side plates and the two flanges.

[0013] By adopting the above arrangement mode of the longitudinal rib structure, the longitudinal rigidity of the structure can be selectively improved for different use scenarios, for example, the longitudinal rib structure can be arranged on the base plate only, or the longitudinal rib structure can be arranged on the side plate only, or the longitudinal rib structure can be arranged on the flange only, and meanwhile, the longitudinal rib structure can be arranged on multiple positions of the base plate, the side plate or the flange.

[0014] As preferred, the longitudinal rib structure is integrally formed with the pile body.

[0015] As preferred, the longitudinal rib structure is formed in a split mode, and the longitudinal rib structure can be mounted and connected with the pile body through a connecting assembly.

[0016] Further, the connecting assembly is a pre-buried bolt, a pre-buried hole is arranged in the longitudinal rib structure, and the mounting and connection of the longitudinal rib structure and the pile body are realized through the cooperation and connection of the pre-buried bolt and the pre-buried hole.

[0017] Further, the connecting assembly is an adhesive, and the adhesive connection of the longitudinal rib structure and the pile body is realized through the adhesive; different types of adhesives can be adopted for longitudinal rib structures made of different materials, for example, epoxy resin adhesive, polyurethane adhesive, acrylic acid, etc.

[0018] As preferred, the material of the longitudinal rib structure is steel reinforced concrete, steel or composite material.

[0019] In summary, the utility model has the following beneficial technical effects:

[0020] 1. The longitudinal rib structure arranged on the base plate, side plate or flange of the U-shaped sheet pile can improve the torsional rigidity of the U-shaped sheet pile in the longitudinal direction, compared with increasing the wall thickness to increase the longitudinal rigidity, the arrangement of the longitudinal rib is more cost-saving, and the overall weight of the U-shaped sheet pile will not be greatly increased.

[0021] 2.

[0022] 3. The U-shaped sheet pile with longitudinal ribs can be applied to the pile sinking construction of a hard bottom layer, so as to avoid longitudinal cracks or damage of the U-shaped sheet pile due to insufficient longitudinal rigidity during pile sinking, and improve the resistance to beating.
