Description

Tower crane pile foundation support wall for bridge construction

technical field

The utility model relates to the technical field of building construction, in particular to a tower crane pile foundation support wall for bridge construction.

Background technique

Tower crane is the most commonly used lifting equipment on construction sites. It is connected by sections, like a steel tower. The equipment for construction raw materials is an indispensable equipment for building construction. When designing tower cranes, the safety of tower cranes is often considered. Because the height of tower cranes is generally high, and the cross-section of its base is small, it is difficult to use in actual use. The toppling of the tower crane may be caused by the unstable foundation; now, the tower crane support wall device is generally installed on the tower crane. arm for stability. In bridge construction, the general buttressing device has no stable support and is difficult to erect. The tower crane may fall due to unstable foundation, which will cause great harm to construction safety and people's property. The horizontal thrust is greater, there will be slight lateral shaking, and the distance between the tower crane and the tower crane's supporting wall becomes difficult to determine, which makes it difficult to install the tower crane's supporting wall. At present, the design of tower crane buttress walls in bridge construction has always been a construction problem.

Compared with the prior art, the utility model uses five reinforced concrete piles implanted in the bottom of the river to provide the stability required by the tower crane, and the piles are connected by brackets. , the brackets are further divided into horizontal brackets and oblique brackets, further reinforced by trusses, the whole structure is very stable, and the supporting wall piles and brackets together form the main body of the pile foundation supporting wall. The buttress pile is fixed by the buttress pole and the attachment frame of the tower crane. The buttress pole has a buttress pole connecting column and a buttress pole hollow column. The buttress pole connection column is inserted into the buttress pole hollow column, and passes through the hollow column The through hole is aligned with the through hole of the connecting column, and then the bolt passes through the two holes at the same time to realize the connection. Since the connecting column of the buttress pole and the hollow column of the buttress pole are arranged with several through holes in the axial direction, the through holes at different positions can be selected for fixing. When the positions are different, the connecting column of the buttress pole is inserted into the hollow column of the buttress pole The depth of the tower crane is also different, so that the length of the whole tower crane wall pole can be stretched and adjusted, which is convenient for installation, especially suitable for the situation where the distance between the tower crane and the tower crane wall is not completely determined in bridge construction.

The utility model has the advantages of stable foundation, simple and stable structure, and adjustable length of the tower crane support wall rod.
