Embodiment Construction

[0046] A kind of large-volume special-shaped caisson foundation construction method of the present invention is described in further detail below in conjunction with the accompanying drawings and specific embodiments:

[0047] The present invention takes the sewage pumping station as an example for specific description. The sewage pumping station adopts a reinforced concrete caisson structure. The plane shape of the caisson 8 is a "dot" shape with one end wide and the other end narrow. The long side of the caisson 8 is 25.8 meters. , the longer wide side is 11.6 meters, and the buried depth is 24.1 meters. According to the depth and form of the caisson structure, the caisson is divided into three sections, and the caisson 8 of the three sections is sequentially fabricated and sunk.

[0048] Such as figure 1 As shown, the specific steps of the caisson foundation construction method of the sewage pumping station include:

[0049](1) Foundation pit measurement and setting out, a...

Abstract

The invention relates to a large-size special-shaped open caisson foundation construction method. The large-size special-shaped open caisson foundation construction method comprises the steps that foundation pit surveying and setting out are conducted, a site is leveled, an open caisson cushion layer is manufactured, and blade foot manufacturing is conducted; then a first open caisson section is prefabricated, an inner side scaffold and an outer side scaffold are erected on the inner side and the outer side of the well wall correspondingly, a formwork is mounted, and concrete is poured; afterthe first open caisson section reaches the design strength, in-well soil taking sinking is conducted; then a second open caisson section is prefabricated, an outer side scaffold is erected on the outer side of the well wall, an operation platform is erected at the top of the first open caisson section, and an inner side scaffold is erected on the operation platform; and the formwork is mounted, concrete is poured, after the second open caisson section is completed, in-well soil taking sinking is conducted, manufacturing sinking of the next open caisson section is conducted according to a manufacturing method of the second open caisson section, and finally open caisson bottom sealing is conducted. According to the open caisson construction method, the scaffold erecting, material using and erecting time can be saved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a large-volume special-shaped caisson foundation construction method. Background technique [0002] With the continuous development of urban municipal engineering construction and the continuous progress of caisson technology, caisson technology has been widely used in urban municipal engineering construction, especially in the construction process of sunken drainage facilities, caisson technology is important in the entire construction process played a pivotal role in. The large-volume special-shaped caisson is a form of underground structures and deep foundations, which has the characteristics of large buried depth and segmented fabrication. [0003] During the construction of traditional caisson technology, before pouring each section of caisson, floor scaffolding needs to be erected on the inside and outside sides of the caisson. From the bottom of the caisson...
