Sheet pile structure for supporting and enclosing shore

Abstract

The invention discloses a sheet pile structure for supporting and enclosing a shore. The sheet pile structure is formed by horizontally and vertically splicing a plurality of structure sheet piles, the Structure comprises a sheet pile main body and two ribs, and the two ribs are mutually parallel and perpendicular with the sheet pile main body to form the structure. The sheet pile is large in resistance to bending moment, strong in soil retaining ability, high in vertical bearing capacity, light in structure weight, small in product lateral-wall friction force, good in product durability and long in full service period, the sheets can be horizontally and vertically connected, the repeatable utilization rate is high, and the sheet pile structure especially plays the role in supporting on water conservancy and marine shore enclosing foundation works.

Description

technical field [0001] The invention relates to sheet piles used in civil engineering such as water conservancy and ocean engineering for bank enclosing, support, soil retaining, and vertical bearing, and in particular to a Π structural sheet pile for supporting and maintaining banks. Background technique [0002] The enclosing, supporting and retaining works in water conservancy and coastal civil engineering are the core and main projects, with large engineering volume, difficult construction and many problems. At present, most of them use steel sheet piles, ordinary concrete sheet piles, and prestressed concrete sheet piles. Carry out works such as enclosing, supporting, and retaining soil, and a small part of them use concrete for masonry. The construction is slow, the excavation volume is large, and it is greatly affected by the weather, so it is less and less used. At present, steel sheet piles are used the most, but the main construction costs are high, the amount of s...

AI Technical Summary

Problems solved by technology

[0002] The enclosing, supporting and earth retaining works in water conservancy and coastal civil engineering are the core and main projects. The engineering volume is large, the construction is difficult, and there are many problems. At this stage, most of them use steel sheet piles, ordinary concrete sheet piles, and prestressed concrete sheet piles. Carry out works such as enclosing, supporting, and retaining soil, and a small part of them use concrete for masonry. The construction is slow, the excavation volume is large, and it is greatly affected by the weather, so it is less and less used

At present, steel sheet piles are used the most, but in engineering, the main cost is high, the steel consumption is large, the energy consumption is high, the anti-corrosion effect is poor, the corrosion is serious for a long time, the vertical bearing capacity is poor, and the moment of inertia is small during the construction process, which is easy to produce The sheet pile is deformed, and the effect of enclosure and support is not good

Concrete sheet piles or prestressed concrete sheet piles generally have a concrete strength of about 30-60 MPa. Concrete itself is very brittle, heavy in weight, high in transportation, construction and installation costs, and the longest single section length does not exceed 15 meters. Generally, it cannot be connected. , and in the application process, the surface of the sheet pile is mainly damaged, cracked, and the friction resistance is large, and the construction is difficult. Some of them need to introduce water jet holes or lubricants to reduce drag. The overall component is heavy, and the construction requirements in soft soil or silt are high. , it is easy to produce waste piles during the construction process, and its corrosion resistance is poor in the surrounding ocean or in saline-alkali medium soil, and the service life cycle is short
