H-shaped support pile and preparation method thereof

Abstract

The invention discloses an H-shaped support pile which comprises a support pile body poured by prestressed reinforcement, hooping and concrete. The cross section of the support pile body is an H-shaped structure formed by two flanges and a web connected between the two flanges. An end plate and a pile hoop are arranged on at least one end of the support pile body. The end plate is arranged on the end face of the support pile and is provided with a hole. The prestressed reinforcement is contained in the hole. The pile hoop and the end plate are fixedly connected or integrally formed and sleeved on the end part of the support pile body. An anchoring rib extending into the support pile body is fixedly connected on the pile hoop or the end plate. The invention further discloses a preparation method of the H-shaped support pile. The H-shaped support pile provided by the invention has the advantages of low cost, fast construction, and high bending resistance and shear strength.

Description

technical field [0001] The invention relates to the technical field of concrete piles, in particular to an H-shaped support pile and a preparation method thereof. Background technique [0002] At present, in foundation pit maintenance engineering and slope stabilization engineering, the enclosure wall formed by reinforced concrete round piles combined with cement mixing piles is often used, and vibrating sinking tube T-shaped piles or SMW construction method (implanted in cement mixing soil with recyclable The large I-shaped steel forms the enclosure wall). Reinforced concrete round pile is a traditional construction method. Since it is a round pile, the direction of the contact surface around the foundation pit is different, so when it is squeezed by the foundation pit, only a single point in one direction plays a supporting role, making the reinforcement Only one steel bar in each direction of the concrete round pile is stressed, which is easy to cause uneven stress, low ...

AI Technical Summary

Problems solved by technology

Reinforced concrete round pile is a traditional construction method. Since it is a round pile, the direction of the contact surface between it and the foundation pit is different. In the process of being squeezed by the foundation pit, only a single point in one direction plays a supporting role, so that the reinforcement There is only one steel bar in each direction of the concrete round pile to bear the force, which is easy to cause uneven force, low bending resistance and low shear resistance; in addition, the reinforced concrete round pile also has high cost, slow construction speed, and construction mud pollutes the environment, etc. Disadvantages: The SMW construction method also has disadvantages such as troublesome recycling of section steel and high cost

[0003] And the traditional round pile, in the manufacturing process, adopts to drill hole first, then puts the steel cage that weaves in the hole, then pours concrete, needs maintenance for a long time when excavating, affects project progress; And above-mentioned this traditional The processing method can only be made at the construction site, the production efficiency is low, and it cannot meet the requirements of large-scale industrial production
