Embodiment Construction
[0049] 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 principles 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.
[0050] refer to figure 1 As shown, the construction method of the full house support system of the steel pipe pile Bailey frame foundation includes the following construction steps:
[0051] 1) Construction preparation: build the construction steel trestle 1 on site, determine the location of the steel pipe pile 2 by surveying and mapping, and prepare the construction devices and materials required for construction;
[0052] 2) Erection of steel pipe pile-guide...

The invention relates to a construction method of a steel pipe pile bailey truss foundation full-space support system. The construction method comprises the following construction steps of 1) construction preparation; 2) erection of a steel pipe pile guide construction platform; 3) installation of a pile cap of a steel pipe pile sinking pile; 4) guide driving of a steel pipe pile; 5) extension construction of the steel pipe pile; 6) arrangement and positioning of a profile steel bottom beam; 7) arrangement of bailey beams; 8) arrangement of distribution beams; 9) laying of a platform plate; and 10) counter-force prepressing of the platform. The construction method has the beneficial effects that a construction trestle is used as a support body of a support longitudinal beam, a support cross beam is arranged on a cantilever section of the support longitudinal beam, the position of a guide groove pipe is limited through the support longitudinal beam and the support cross beam, the erection difficulty of the steel pipe pile guide construction platform is reduced, and the structural stability is improved; and a sliding hoop and a sliding control plate are arranged on the outer side wall of the steel pipe pile, the sliding control plate is connected with a position control groove plate, and the transverse position of the steel pipe pile can be limited through the position control groove plate.
Description
technical field [0001] The invention relates to a construction method of a steel pipe pile Bailey frame foundation full-hole support system, belongs to the field of bridge engineering, and is suitable for the construction project of a steel pipe pile Bailey frame foundation full-hole support. Background technique [0002] There are various forms of supports for cast-in-place beam construction in China. Reasonable selection of support types has an important impact on improving construction quality and efficiency. Among them, the steel pipe pile Bailey frame foundation full support has the characteristics of high strength, rigidity and good stability, and is often used as the construction support form of cast-in-situ concrete continuous beam bridges. However, in the construction process of erecting the full house support system of the steel pipe pile Bailey frame foundation, there are often problems such as low positioning accuracy of steel pipe piles, difficulty in adjusting ...
