Prestressed reinforcement and non-prestressed reinforcement combined H-shaped reinforced concrete sheet pile and manufacture method thereof

Abstract

The invention relates to a prestressed reinforcement and non-prestressed reinforcement combined H-shaped reinforced concrete sheet pile and a manufacture method thereof. The H-shaped reinforced concrete sheet pile adopts an I-shaped structure; and prestressed reinforcement and non-prestressed reinforcement are arranged in the H-shaped reinforced concrete sheet pile at the same time. Compared with the prior art, the H-shaped reinforced concrete sheet pile has the advantages of good bending resistance and shearing resistance, low cost, high efficiency, zero contamination, environmental protection and the like.

Description

technical field [0001] The invention relates to an H-shaped reinforced concrete sheet pile, in particular to an H-shaped reinforced concrete sheet pile combined with prestress and non-prestress. Background technique [0002] At present, in civil and industrial buildings, most of the following methods are used for foundation pit enclosure: [0003] 1. Insert H-shaped steel into the cement-soil mixing pile as water stop and soil retaining. Most of the H-shaped steel is leased, and the longer the time, the higher the rent. In addition, there is no place to park the crane in some areas, so the steel cannot be pulled out, and the cost is higher. bigger. [0004] 2. Using bored piles to retain soil and cement-soil mixing piles to stop water, the cost is high, the waste is large, and the mud pollutes the environment. [0005] 3. The use of multi-row cement-soil mixing piles - gravity dam, as a water stop and soil retaining, the prerequisite is that the surrounding space is large,...

Problems solved by technology

[0003] 1. Insert H-shaped steel into the cement-soil mixing pile as water stop and soil retaining. Most of the H-shaped steel is leased, and the longer the time, the higher the rent. In addition, there is no place to park the crane in some areas, so the steel cannot be pulled out, and the cost is higher. bigger

[0004] 2. Bored piles are used to retain soil, and cement-soil mixing piles are used to stop water, which is costly, wasteful, and mud pollutes the environment

[0005] 3. The use of multi-row cement-soil mixing piles - gravity dam, as a water stop and soil retaining, the prerequisite is that the surrounding space is large, but it cannot be used as an enclosure for deep foundation pits
