Embodiment Construction

[0038] The present invention will be further described below in conjunction with the examples. The description of the following examples is provided only to aid the understanding of the present invention. It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, some improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.

[0039] refer to figure 1 As shown, the construction method of the cast-in-place bridge steel pipe pile underwater support removal system includes the following construction steps:

[0040] 1) Construction preparation: review and determine the position of the steel pipe pile 1, delineate the material stacking site on the bridge deck beam 2; prepare the construction devices and materials required for the demolition construction;

[0041] 2) Protection of the botto...

Abstract

The invention relates to a construction method for a cast-in-place bridge steel pipe pile underwater support removal system, comprising the following construction steps: 1) construction preparation; 2) bottom protection of bridge deck beams; 3) removal of steel beams and erection of supports; 4) removal of transverse steel beams ; 5) Removal of longitudinal steel beams; 6) Cut-off construction of steel pipe piles; 7) Pulling out of steel pipe piles. The beneficial effects of the present invention are: the present invention can limit the transverse steel beam and the longitudinal steel beam through the sliding connecting body, and can reduce the interface friction by means of the ball at the bottom of the groove in the sliding connecting body; at the same time, the present invention can The sliding adjustment bolt and the strut adjusting bolt can precisely control the position of the sliding connecting body, which reduces the difficulty of spatial positioning; in addition, the setting of the first support hoop and the second support hoop on the outer side of the steel pipe pile is helpful for lifting Integrality of the structure; the present invention sequentially arranges a light backing plate and a flexible protective net on the lower surface of the bridge deck beam, which can provide construction protection for the bridge deck beam and improve the safety of the construction structure.

Description

technical field [0001] The invention relates to a construction method for a cast-in-place bridge steel pipe pile underwater support removal system, which belongs to the field of bridge engineering and is suitable for the cast-in-place bridge steel pipe pile underwater support removal project. Background technique [0002] With the gradual maturity of bridge construction technology in our country, steel pipe pile underwater support has been widely used in cast-in-place beams. However, the removal of steel pipe pile underwater support has always been a difficult point in on-site construction. At present, when the support of steel pipe piles is removed in water, there are often problems such as small construction area and low efficiency of demolition construction, and when removing the longitudinal Bailey beams, there is a risk of overturning due to the lateral movement of the Bailey beams, which seriously affects the safety of construction sex. [0003] In the prior art, ther...
