Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and examples, and the contents of the examples are not intended to limit the protection scope of the present invention.

[0023] Before introducing the connection method of the reaction pile and the main girder of the present invention, the connection device used in the connection method will be introduced first.

[0024] figure 1 It shows a longitudinal sectional view of the connection device used in the connection method of the reaction pile and the main girder of the present invention. see figure 1 , the connecting device includes an intermediate cylinder 1 . The intermediate cylinder 1 is used for force transmission. In the present invention, preferably, as figure 1 , 3 As shown in and 4, a plurality of reinforcing ribs 8 are arranged in the middle cylinder 1. By arranging the ribs 8, the strength of the middle cylinder 1 can be improved, thereby improving its a...

Abstract

The invention relates to a connection method for a counterforce pile and a main beam. According to the connection method, the counterforce pile and the main beam are connected through a connecting device. The connection method comprises the following steps that (1) the counterforce pile and a flange (3) of the connecting device are connected through threads or an anchor lock; and (2) the main beam and a flange plate (4) of the connecting device are connected through threads or an anchor lock. By the adoption of the method, stress of the counterforce pile and the main beam is even and not eccentric; meanwhile, operation is easy, the construction period is short, and experimentation cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of construction engineering quality detection, and relates to the connection between a reaction pile and a main beam in a single static load test of a large-diameter concrete pouring pile, and in particular to a reaction pile and a main beam in a single static load test of a large-diameter concrete pouring pile connection method. Background technique [0002] In construction engineering, a single load test must be carried out on large-diameter concrete pouring piles to test the vertical compressive (pull-out) bearing capacity of single piles of large-diameter pouring piles. When performing a single load test on large-diameter concrete pouring piles, the reaction piles should be connected to the main beam. [0003] However, currently in construction engineering testing, a method is to simply use steel bars to connect the reaction piles to the main beam, and another method is to use a simple circular sleeve t...
