Embodiment Construction

[0029] The application will be described in further detail below in conjunction with the accompanying drawings.

[0030] At present, when excavating deep foundation pits, some construction sites use tower cranes to lift earthwork, but this method of earthwork transfer is inefficient, and tower cranes take up a lot of space, cost high, and have low cost performance; some construction sites use The inclined belt is used for earthwork transportation, but the space occupied by the belt in the foundation pit is still large, and as the depth of the foundation pit increases, the position of the belt needs to be adjusted, which is laborious and time-consuming, not only not suitable for small sites with deep The excavation of the foundation pit, and the construction cost is high, and the excavation efficiency is low.

[0031] In view of the low excavation efficiency of deep foundation pits mentioned above, this application has developed a rapid excavation system for ultra-deep foundati...

Abstract

The invention relates to a rapid soil discharging system for an ultra-deep foundation pit, and relates to the field of foundation pit soil discharging in engineering construction. The rapid soil discharging system comprises a supporting frame installed in the foundation pit, a driving chain wheel, a driven chain wheel, a chain wound around the driving chain wheel and the driven chain wheel, a plurality of hoppers fixed to the chain and a power part installed on the supporting frame, wherein the driving chain wheel and the driven chain wheel are rotationally connected to the supporting frame; and the bottom of the supporting frame is installed at the bottom of the foundation pit, the side end of the supporting frame is installed on the inner wall of the foundation pit, the driving chain wheel is located over the driven chain wheel and located above the top of the foundation pit, and the power part is connected with the driving chain wheel to be used for driving the driving chain wheel to rotate. The soil discharging efficiency of the deep foundation pit is improved.

Description

technical field [0001] The application relates to the field of foundation pit excavation in engineering construction, in particular to a rapid excavation system for ultra-deep foundation pits. Background technique [0002] Before the construction of the project, it is necessary to dig a foundation pit on the construction site, then carry out the construction of the building foundation at the bottom of the foundation pit, and then carry out the construction work of the building on the foundation. [0003] When excavating the foundation pit, the depth of the foundation pit will also be different for buildings of different heights. When the construction of high-rise buildings is required, deep foundation pits will be dug on the ground, and for some small sites, deep foundation pits need to be excavated, especially for foundation pits with a depth of more than 50m , the traditional earth and stone excavation mainly adopts the method of vertical grabbing to take soil, and then t...
