Problems solved by technology

That is, it is necessary to install embedded parts between the concrete columns, which will have an adverse effect on the appearance quality of the concrete columns;
[0006] 3) When the bridge deck design is relatively wide, the original structural design will generally design the upper structure of the column as a "vase" style to meet the stability needs of the bridge cross section; this will bring certain difficulties to the installation of the tower crane

Embodiment

[0018] Example: as figure 1 , 2 As shown, this embodiment specifically relates to a tower crane foundation setting method applied to a bridge. The bridge is a six-tower single-cable plane short tower beam cable-stayed bridge. The whole bridge has six main towers, and each main tower has a lower structure tower. The height is 21-25M, and the two are symmetrical. The top of the tower is composed of two tie beams.

[0019] The tower crane foundation setting method simplifies the construction method and reduces the construction cost by setting the tower crane foundation on the top surface of the lower tower column, and specifically includes the following steps:

[0020] (1) The concrete pouring of the lower pylon is completed. The lower pylon consists of a column 1, a side tie beam 2 and a middle tie beam 3. The two side tie beams 2 are symmetrically arranged on both sides of the middle tie beam 3, and the three are horizontal and horizontal. It is connected between two vertical...

Abstract

The invention discloses a tower crane foundation arrangement method applied on a great bridge. The tower crane foundation arrangement method is characterized by comprising the following steps that after concrete pouring of lower tower columns is completed, built-in fittings used for installing a tower crane are arranged on the top faces of the lower tower columns; steel bars and formworks are installed on the top faces of the lower tower columns, and concrete pouring of upper tower columns is completed; the built-in fittings located on the top faces of the lower tower columns are sprung out to be used for connecting foundation components of the tower crane, and then installation of the tower crane is completed on the foundation components. The tower crane foundation arrangement method has the advantages that the construction method is simple and convenient, operation is easy, and the construction cost can be effectively lowered.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and particularly relates to a tower crane foundation setting method applied to a bridge. Background technique [0002] The setting of tower crane foundation is extremely common in bridge construction in my country. Especially in the construction of large bridges, to solve the problem of vertical transportation, tower cranes are often set to solve this problem. However, the foundation of the tower crane is generally set on the foundation of the bearing platform, which is more intuitive and the force is more clear. [0003] However, when the tower crane foundation is set on the platform foundation, the following problems may generally be encountered: [0004] 1) When the area of ​​the bearing platform is not enough to set the tower crane foundation, the root of one side of the tower crane will be "lost". At this time, the temporary corbel cantilevered on the edge of the bearing platfor...
