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: such as figure 1 , 2 As shown, this embodiment specifically relates to a tower crane foundation setting method applied to a large bridge. The bridge is a cable-stayed bridge with six towers, single cable plane, and low tower girder. The whole bridge has 6 main towers, and each main tower has a lower structural tower The body height is 21-25M, symmetrical in pairs, and the top of the tower column is composed of 2 tie beams.

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

[0020] (1) Complete the concrete pouring of the lower tower column. The lower tower column is composed of column 1, side beam 2 and middle beam 3. Two side beams 2 are symmetrically arranged on both sides of the middle beam 3, and the three are horizontal and transverse It is connected...

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 in particular 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 our country. Especially in order to solve the problem of vertical transportation in the construction of large bridges, tower cranes are often set up to solve this problem. However, the foundation of its tower crane is generally set on the cap foundation, which is more intuitive and the force is more clear. [0003] However, the following problems may generally be encountered when setting up the tower crane foundation on the cap foundation: [0004] 1) When the area of ​​the cap is not enough to set up the foundation of the tower crane, the root of one side of the tower crane will "fall through the air". At this time, it will be solved by using a temporary corbel overhanging the side ...
