Technical Field
The utility model relates to a building engineering technical field especially relates to an enhancement mode U type sheet pile.
Background
The U-shaped sheet pile is a novel retaining component of a prestressed concrete foundation enclosure, and because the U-shaped sheet pile adopts a unique variable cross-section structural design, the width of the cross section is increased while the height of the cross section is increased and the bending moment of the cross section is increased. In the production process, the sheet pile member is usually prepared by mixing and stirring cement and mineral admixture, then performing a vibrating process, and curing by using a normal pressure steam curing process. The normal pressure steam curing process is a method for curing the sheet pile in a steam environment after the sheet pile is vibrated and formed, and is a curing process for promoting the rapid hydration of cement, the rapid condensation of concrete and corresponding strength. The process has the characteristics of short curing time (6-7 hours) and quick concrete strength increase (more than 40 MPa). The speed of depositing and taking out is too slow in present sheet pile maintenance line, and the maintenance temperature is inhomogeneous moreover, and sheet pile each point intensity increases inconsistently, can appear weak position even, influences sheet pile component bulk strength. In civil engineering, the soil and water retaining structure needs to bear external horizontal pressure load, the structure mainly bears the action of bending moment, but larger shearing force is often generated at the sudden change position of the load, and shearing failure can be generated if the shear strength of the structure is insufficient, such as the bottom position of the soil retaining structure, the horizontal supporting position of a foundation pit project and the like. The traditional soil retaining structure is mainly cast in place or manufactured on site, needs a larger construction site and longer maintenance time, and has the characteristics of straight structural surface and no attractive appearance. The soil guard structure is easy to crack and expose ribs at a position with larger shearing force, which not only influences the appearance, but also influences the stress performance of the structure.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an enhancement mode U type sheet pile overcomes above-mentioned prior art's is not enough, improves U type sheet pile's bending resistance.
The utility model discloses the purpose is realized through following technical scheme:
an enhanced U-shaped sheet pile comprises a concrete main body, wherein reinforcing steel bars are longitudinally arranged in the concrete main body; the concrete main body comprises an upper concrete structure, the two ends of the upper concrete structure are respectively and vertically connected with a middle concrete structure at the same side, the opposite sides of the two middle concrete structures are inner sides, and the outer side of the other end of the middle concrete structure is respectively and vertically connected with a lower concrete structure.
Furthermore, the steel bars comprise an upper row of steel bars and a lower row of steel bars; the upper row of steel bars is distributed in the upper concrete structure, and the lower row of steel bars is distributed in the lower concrete structure.
The structure is characterized by further comprising a structure web rib, wherein the structure web rib is distributed in the upper concrete structure, the middle concrete structure and the lower concrete structure, and the structure web rib connects the upper row of reinforcing steel bars with the lower row of reinforcing steel bars.
The utility model provides an enhancement mode U type sheet pile improves U type sheet pile's bending resistance, has saved U type sheet pile's concrete and reinforcing bar quantity simultaneously, improves the component overall stability; because the section of the enhanced U-shaped sheet pile is regular, the manufacturing difficulty is reduced, and the construction efficiency is improved.
