Example Embodiment

[0018] Example 1

[0019] like figure 1 , figure 2 , image 3 Shown is the jack push support method. The hinge support B is placed in the grooved slideway 5. There are several positioning holes 6 on the side of the grooved slideway 5. A bearing is tightly installed on the outer surface of the grooved slideway 5. The force base 7, the load base 7 is inserted into the soil anchor rod 12 to strengthen the fixing effect, and the jack 8 is installed between the load base 7 and the sliding hinge support B, and the sliding hinge support B is under the horizontal external force of the jack 8 during construction Carry out horizontal push movement in sections in the direction of the fixed hinge support A. When the jack 8 reaches the limit position, use the load-bearing channel steel 9 to penetrate into the positioning hole 6, respectively fix the sliding hinge support B and the jack 8, and then loosen them. Sliding hinge support B, continue to push the jack 8 until it reaches the de...

Example Embodiment

[0020] Example 2

[0021] like figure 1 , Figure 4 , Figure 5 Shown is the through-the-center jack traction support method, the other end point of which is the sliding hinge support B placed in the groove-shaped slideway 5, and the inner side of the groove-shaped slideway 5 is equipped with a load-bearing pedestal 7, bearing The force pedestal 7 is inserted into the soil anchor rod 12 to strengthen the fixing effect, and the outer surface of the force pedestal 7 is equipped with a through-type jack 11, and the through-type jack 11 is connected with the sliding hinge support B with a steel strand 10, and slides during construction. Under the action of the horizontal external force of the through-hole jack 11, the hinge support B is continuously pulled in the direction of the fixed hinge support A through the steel strand 10 until it reaches the design position of the slide hinge support B.

Example Embodiment

[0022] Example 3

[0023] like figure 1 , Image 6 , Figure 7 Shown is the traction sliding hinge support method of the fixed hinge support of the through-hole jack, and the other end point is the sliding hinge support B which is placed in the groove-shaped slideway 5, and the through-hole jack 11 is placed on the fixed hinge support. One side of the seat A, one side of the steel strand 10 passes through the node of the fixed hinge support A and is connected with the through-hole jack 11, and the other side of the steel strand 10 is connected with the sliding hinge support B, and slides during construction. Under the action of the horizontal traction force of the through-hole jack 11, the hinge support B continuously moves horizontally towards the fixed hinge support A through the steel strand 10 until it reaches the design position of the slide hinge support B.

Abstract

A construction method for integrally formed cylindrical reticulated shell with horizontal slide structure is disclosed. A cylindrical reticulated shell is divided into two segments for individual assembly. Its one end is a fixing hinge and its another end is a slide hinge in slide way. The hinged points between two segments are borne on temporary supporter. Both slide hinges are horizontally moving until they reach designed positions and the slide hinges are fixed to base. When hinged point reached designed height, a horizontal rod is linked to fix the hinged points. Its advantages are short period, and low cost.

Description

technical field [0001] The invention relates to a construction method of a cylindrical reticulated shell, which is an integral forming construction method of a horizontal sliding structure of a cylindrical reticulated shell support. Background technique [0002] Commonly used construction methods for cylindrical reticulated shells are: (1) high-altitude bulk method; (2) high-altitude sliding method; (3) strip and block installation method; (4) overall hoisting method; (5) overall lifting method; (6) Overall jacking method. These construction methods have their own characteristics, but there are the following problems to varying degrees: a large amount of temporary support scaffolding, a long construction period; The splicing is difficult; the safety hazard of the temporary load-bearing support is prominent; the stability of the jacking device is prominent, etc. Contents of the invention [0003] The purpose of the present...
