Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and particularly relates to an octagonal assembled tower crane retaining wall. Background Art

[0002] The existing tower crane retaining walls are divided into two types, one is brick - built and the other is assembled; the traditional brick - built scheme is as follows: for the tower crane retaining wall where the tower crane foundation elevation is lower than the outdoor ground level, red bricks are used for masonry. According to the size of the tower crane foundation, a 240 - thick circular retaining wall is built, which is more than 0.3m above the outdoor ground elevation. The inner side of the retaining wall is plastered with 15 - mm - thick 1:2.5 cement mortar, and wooden squares are used as internal supports on the inner side of the retaining wall. The assembled scheme has higher structural strength and better safety than the brick - built retaining wall. However, in traditional assembled schemes, for example, in the Chinese patent with the publication number CN111719584A and the patent name of "A tower crane assembled retaining wall component", it is recorded that "the assembled retaining wall is composed of a plurality of single - section bases stacked vertically, and each single - section base includes two fitting parts inserted into each other, and a vertical insertion part is arranged between the two fitting parts." And in the Chinese patent with the publication number CN115369914A and the patent name of "Tower crane assembled retaining wall structure and its construction method", it is recorded that "the first vertical joints between adjacent two first precast retaining wall panels are arranged in a staggered manner with the second vertical joints between adjacent two second precast retaining wall panels." It is not difficult to see that for the assembled retaining wall constructed by splicing, there are many components, which are commonly circular or arched structures, and all require vertical stacking with vertical joints arranged in a staggered manner, making the stability of the retaining wall related to the accuracy of the vertical joint staggering of workers during actual construction.
