Embodiment Construction
[0043] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0044] like Figures 1 to 5 As shown, a method for constructing an underground diaphragm wall using a steel caisson technology includes a single-piece underground diaphragm wall and a steel corner column 6 located at the junction of the single-piece underground diaphragm wall and fixedly connected to the single-piece underground diaphragm wall. It is formed by arranging and connecting a plurality of caisson components, and the caisson components include a steel caisson 1 and a connecting steel box 3;
[0045] Between the steel corner column 6 and its adjacent caisson members, and on the opposite surfaces of the adjacent caisson members in the single-piece underground continuous wall, a guiding mechanism composed of a convex rail and a guide groove is arranged;
[0046] In this embodiment, one end of the steel caisson 1 is fixed with a pr...

The invention provides a method for constructing an underground diaphragm wall using steel caisson technology, which includes a single-piece underground diaphragm wall and a steel angle column located at the junction of the single-piece underground diaphragm wall and fixedly connected with the single-piece underground diaphragm wall. The single-piece underground diaphragm wall consists of A plurality of caisson components are arranged and connected, and guiding mechanisms are set between the steel corner columns and their adjacent caisson components, and adjacent caisson components in a single underground continuous wall; 1. The caisson components between adjacent steel corner columns are sunk into the soil: pull out the longitudinal steel plates of each caisson component to form a continuous wall groove; replace the mud in the groove and pour concrete; insert reinforcement cages in the wall groove if necessary. The invention cancels the process steps that must be done in the early and late stages of the traditional underground diaphragm wall; continuous construction, complete molding, and excellent quality; small construction machines can be used for construction; the construction period is greatly shortened, the adverse impact of construction is greatly reduced, and economic and social benefits significantly.
Description
technical field [0001] The invention relates to a method for constructing an underground continuous wall by utilizing a steel caisson technology. Background technique [0002] The underground diaphragm wall is a kind of grooving machine on the ground. Along the peripheral axis of the deep excavation project, under the condition of mud wall protection, a narrow and long deep groove is excavated. After the groove is cleared, the steel cage is suspended in the groove. , and then use the conduit method to irrigate the underwater concrete to build a unit groove section, so that it is carried out section by section (actually divided into A and B sections at intervals), and a continuous reinforced concrete wall is built underground. The underground diaphragm wall is generally suitable for the construction of underground buildings and structures. The wall area completed in one year in China is more than one million square meters. Almost all subway stations use the underground diaphr...
