Description

Pi-shaped reinforced concrete precast pile

Technical Field

The utility model relates to a reinforced concrete precast pile technical field especially relates to a pi shape reinforced concrete precast pile.

Background

With the development of innovation and opening, the urbanization process is accelerated, more and more people start to turn to cities from rural areas, so that urban population is suddenly increased, and land use is tense. Therefore, various high-rise and super high-rise buildings are built, various underground structures are developed unprecedentedly, the problem of natural foundation bearing capacity needs to be solved, and the problem is solved by arranging pile foundations generally when the underground structures are built.

At present, as a traditional foundation pile project, there are many prefabricated reinforced concrete piles, such as tubular piles, square piles, and the like. Although the section forms of the piles are relatively easy to manufacture, the reinforced concrete precast piles with the section forms have the advantages of large concrete consumption, energy conservation, environmental protection, large self weight, inconvenient transportation and low efficiency. In the construction of foundation pile engineering, the soil squeezing effect exists in the tubular pile and the square pile in the pile forming process, so that the soil body structure around the pile is disturbed, the stress state of the soil body is changed, and negative effects are generated on buildings or underground pipelines around the construction engineering field.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a novel structure, compressive property and resistance to plucking performance are good, and energy-concerving and environment-protective reinforced concrete precast pile.

In order to solve the problems, the technical scheme adopted by the utility model is that the precast reinforced concrete pile comprises a concrete pile body and a pile tip at the lower end of the pile body, wherein the lower end of the pile body and the pile tip are connected into a whole; the cross section of the concrete pile body is pi-shaped, and a steel reinforcement framework is arranged in the concrete pile body.

Preferably, the method comprises the following steps:

the steel bar framework comprises longitudinal bars and stirrups, and the cross section of the steel bar framework is pi-shaped.

The lower end of the pile body is connected with a pile tip.

The utility model provides a beneficial effect that technical scheme brought is:

the utility model discloses a cross-section is pi shape, compares with traditional tubular pile and square pile, is guaranteeing under the compressive property of the concrete pile body and the prerequisite that resistance to plucking performance does not descend, has reduced the quantity of concrete, has reduced engineering cost, and specific advantage is as follows:

compared with the traditional tubular pile and square pile, the concrete pile body of the utility model has the advantages of reduced volume, reduced weight of pile sinking and reduced abrasion degree to the pile hanging machine;

compared with the traditional tubular pile and square pile, the concrete pile body of the utility model has the advantages that the volume is reduced, so that the contact area between the cross section of the pile body and the soil body is reduced, and the soil squeezing effect is reduced in the foundation pile engineering construction;

concrete pile body, compare with traditional tubular pile and square stake, the volume reduces, weight reduction has reduced transportation machinery's consumption of power in the transportation.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Fig. 1 is a pi-shaped precast reinforced concrete pile, which consists of a pile body 1 and a pile tip 2.

The lower end of the pile body is connected with the pile tip into a whole.

As shown in fig. 4, the cross section of the pile body is pi-shaped, a steel reinforcement framework 3 is arranged in the concrete pile body, the steel reinforcement framework comprises longitudinal reinforcements 4 and stirrups 5, and the cross section of the steel reinforcement framework is also pi-shaped.

Compared with the traditional tubular pile and the square pile, the pi-shaped reinforced concrete precast pile reduces the consumption of concrete and greatly reduces the construction cost on the premise of ensuring that the compression resistance and the pulling resistance of the concrete pile body are not reduced; the pile body volume of the pi-shaped concrete pile body is reduced, and the soil squeezing effect in the pile forming process is reduced; and because the consumption of concrete is reduced, the weight of the pile body is reduced, and the abrasion degree of the pile hanging machine and the power consumption of the transportation machinery in the transportation process are reduced.
