Problems solved by technology

This encounters transportation problems, namely the cost and inconvenience of transportation; more steel bars are arranged inside the prefabricated piles for hoisting, which brings a lot of workload to the post-processing of piles; at the same time, the pile length is generally controlled within 12 meters. For deeper foundations, it is also necessary to pick up piles on site.
Therefore, it not only increases the construction difficulty, but also increases the project cost.

Abstract

The present invention relates to a construction method of in-situ X-shaped reinforced concrete pile. It is characterized by that the lower portion of its vibrating head is connected with cover plate, the cover plate is connected with X-shaped steel sleeve, said X-shaped steel sleeve has a hollow cavity, the lower end of X-shaped steel sleeve is connected with prefabricated X-shaped reinforced concrete pile shoe. Its construction method includes the following steps: starting vibrating head to downwards drive the X-shaped steel sleeve, and under the protection of prefabricated X-shaped pile shoe driving the X-shaped steel sleeve into foundation, pouring the concrete into the hollow cavity interior of X-shaped steel sleeve, utilizing the vibrating head to make vibration, upwards drawing out the X-shaped steel sleeve from ground, remaining the X-shaped reinforced concrete pile shoe in the foundation so as to form the invented in-situ X-shaped reinforced concrete pile.

Description

technical field [0001] The invention relates to a novel construction method of cast-in-place reinforced concrete piles, in particular to a construction method of cast-in-place X-shaped reinforced concrete piles. Background technique [0002] Before the present invention, in the field of foundation engineering, circular cast-in-place reinforced concrete piles were widely used in engineering, and the bearing capacity of circular pile foundations was mainly formed by pile side friction resistance and pile tip resistance. However, this circular cast-in-place reinforced concrete pile consumes a large amount of reinforced concrete, resulting in high construction costs. How to reduce the amount of reinforced concrete and improve the bearing capacity of pile foundation has been a long-term concern of researchers. The Chinese patent "Prefabricated X-shaped Reinforced Concrete Pile" (Patent No. 01218447.0) invented the prefabricated X-shaped reinforced concrete pile. Compared with th...
