Method for producing H-shaped support piles

Abstract

The invention provides a method for producing H-shaped support piles which are low in cost, bending resistant, shearing resistant and high in intensity. The technical scheme includes that the method specifically includes: (1) placing stop plates on the baseplate of an H-shaped support pile die or at two ends of the baseplate, serially connecting the stop plates on prestressed steel via holes on the stop plates, serially connecting a plurality of stirrups on the prestressed steel, connecting one end of the prestressed steel on a first tensioning device, and connecting the other end of the prestressed steel on a second tensioning device; and (2) adjusting distributing distance of the stop plates and the stirrups, closing the H-shaped support pile die to tension the prestressed steel, and the like.

Description

technical field [0001] The invention relates to the technical field of concrete piles, in particular to a production method of H-shaped support piles. Background technique [0002] At present, in the foundation pit maintenance project and slope stabilization project, the retaining wall formed by reinforced concrete round piles combined with cement mixing piles is often used, and vibrating tube sinking T-shaped piles or SMW construction method (implanting recyclable piles in cement mixing soil) are often used. 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 There is only one steel bar in each direction of the concrete round pile to bear the force, which is easy to cause u...

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 in the concrete round pile, which is easy to cause uneven force, low bending and shear resistance; traditional round piles, in the production process, first drill holes, and then place them in the holes Weaving reinforced cages, and then pouring concrete, it takes a long time to maintain when excavation, which affects the progress of the project; and the above-mentioned traditional processing method can only be made on the construction site, the production efficiency is low, and it cannot meet large-scale industrialization Production requirements
