Deep foundation pit retaining wall structure and construction method of underground space structure
The invention provides a deep foundation pit retaining wall structure. The deep foundation pit retaining wall structure comprises a barrel-shaped retaining wall body, a water pipe through from top tobottom is arranged in the barrel-shaped retaining wall body in a poured mode, and the water pipe is provided with a water outlet which is located in the lower end face of the barrel-shaped retaining wall body and a water inlet which is located in the upper end face of the barrel-shaped retaining wall body. By means of the design, on one hand, water can be injected into a soil body located on the lower end face of the barrel-shaped retaining wall body through the water pipe to soften the soil body, so that the purpose of reducing the end resistance of the barrel-shaped retaining wall body is achieved, and then sinking of the barrel-shaped retaining wall body is facilitated; on the other hand, the softened soil body can further facilitate excavation, and the construction progress is improved; moreover, scouring can be carried out on the soil body located below the lower end face by using a method of injecting high-pressure water flow, so that the barrel-shaped retaining wall body sinks by virtue of gravity; and in this way, the purposes of reducing construction procedures, reducing construction noise, shortening the construction period and then reducing pollution to the surrounding environment can be finally achieved. The invention further discloses a construction method of an underground space.
本发明提供了一种深基坑挡墙结构，包括：筒型挡墙本体，其中，所述筒型挡墙本体内浇筑有上下贯通的水管，所述水管具有位于所述筒型挡墙本体的下端面出水口，和位于所述筒型挡墙本体的上端面的进水口。通过以上设计，一方面可以通过水管向位于所述筒型挡墙本体的下端面的土体注水，以软化土体，从而达到减少筒型挡墙本体端阻力的目的，以利于筒型挡墙本体的下沉，另外，软化土体也可以利于挖掘，提高施工进度；再者，可以通过注入高压水流的方式对位于所述下端面以下的土体进行冲刷，以使筒型挡墙本体凭借重力下沉；这样最终可以实现施工工序的减少，施工噪声减小，工期缩短，进而对周边环境带来的污染减少的目的；又公开了地下空间的施工方法。
