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

Embodiment Construction

[0024] Attached below figure 1 To attach Figure 4 The invention is described in further detail.

[0025] The mold used in the present invention to produce the H-type support pile is commonly called the H-type support pile mold, and the mold structure adopted is that the application number is 201220469886.0, but the mold for actually producing the H-type support pile is not limited to the above-mentioned Mould, as long as can reach the mold of the utility model production effect all can.

[0026] A kind of production method of H type support pile, it is characterized in that: concrete manufacturing step comprises:

[0027] (1) Place the baffle 1 on the bottom plate of the H-shaped support pile mold or at both ends of the bottom plate. And through the hole on the baffle connected in series on the prestressed steel bar 2, at the same time several stirrups 3 are also connected in series on the prestressed steel bar 2, and one end of the prestressed steel bar is connected on th...

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...
