[0002] In construction engineering, tower crane is a common hoisting equipment for lifting and carrying heavy objects. The stability of tower crane is crucial to ensure construction safety, so the foundation design of tower crane is particularly important. In bridge construction, due to the special structure of bridge pier, the traditional concrete foundation may not meet the requirements. Therefore, a specially designed foundation device is needed to adapt to the special structure of bridge pier.

[0003] Through retrieval, the patent with publication number CN207987956U discloses a bridge-mounted tower crane foundation, which comprises a No. 1 bridge pier pile cap and a No. 2 bridge pier pile cap. The No. 1 bridge pier pile cap is provided with a No. 1 main bridge tower body on the upper side, and a No. 1 bridge pier group pile is arranged on the lower side of the No. 1 bridge pier pile cap. The No. 1 bridge pier pile cap is provided with a No. 2 bridge pier pile cap on one side, and the No. 2 bridge pier pile cap is provided with a No. 2 main bridge tower body on the upper side. The No. 2 bridge pier pile cap is provided with a No. 2 bridge pier group pile on the lower side. The No. 1 bridge pier pile cap and the No. 2 bridge pier pile cap are connected through a base plate. The base plate is provided with a support column at the bottom. The support column is connected with the No. 1 bridge pier pile cap and the No. 2 bridge pier pile cap through a metal fixed plate. A tower crane foundation pile cap is cast on the base plate. The outer surface of the tower crane foundation pile cap is provided with an anti-weathering layer. The base plate is made of stainless steel plate, which facilitates the casting of the tower crane foundation pile cap and effectively prevents water from corroding the bottom of the tower crane foundation pile cap.

The common water level of the river is higher than the top surface of the bridge pier pile cap. The tower crane foundation lacks a dry and stable environment, which cannot ensure the normal operation of the tower crane, resulting in slow bridge construction speed. Therefore, there are certain limitations. UTILITY MODEL CONTENTS
