Abstract

The invention provides a deep foundation pit reinforced concrete supporting pile. One side of a web is connected with a flange I, a thickened section is arranged at one end of the web, a connecting and fixing part is arranged on the thickened section, and a steel strand is internally and vertically buried on the other side of the web. The manufacturing and the installing methods of the deep foundation pit reinforced concrete supporting pile include the steps as follows: a combined steel reinforcement cage composed of a web-shaped cage body part, a flange I-shaped cage body part and a thickened section cage body part arranged at one end part of the web-shaped cage body part is formed, the web-shaped cage body part is vertically provided with the steel strand on one side, and the thickened section cage body part is provided with the connecting and fixing part. A combined form composed of a monolithic moving side form and a fixed bottom form is adopted, and the deep foundation pit reinforced concrete supporting pile with the web and the flange I is made through pouring concrete after the combined steel reinforcement cage is positioned into the combined form; a connecting plate with two ends opened with through holes is made; a pile driver is used for pressing the first pile into the ground in a way that the thickened section faces upwards, when the top end is close to the ground, the second pile is abutted with the first pile through the connecting plate in a manner that the thickened section faces downwards and the flange I faces upwards, so as to press the second pile into the ground.

Description

technical field

[0001] The invention relates to a deep foundation pit support pile in a basement of a building and a manufacturing and embedding method thereof. Background technique

[0002] Deep foundation pit support is a relatively complex engineering technology in construction engineering. In the construction of deep foundation pits in soft soil areas, the support method of enclosure piles plus supports or anchor rods is generally used. The most widely used enclosure piles are Bored cast-in-situ piles, although this type of pile has the advantages of convenient construction, safety and reliability, and little impact on the surrounding environment, but its section form as a bending member is very unreasonable, and the waste of materials is serious; and this type of pile is used in pile construction. A large amount of mud produced pollutes the environment, and the cost of mud discharge is high, so the overall cost is high. Prefabricated reinforced concrete special-shaped ...
