Problems solved by technology
[0003] The deficiencies of the general construction deep foundation pit protection device are: after the general foundation pit is excavated, workers will be required to enter the foundation pit for construction operations, such as building some brackets and related protective devices to support the inner wall of the foundation pit to avoid The inner wall of the pit collapsed, but during the construction process, it is very likely that the soil will not be firm enough to cause a collapse, which will bring danger to the workers performing related operations. At the same time, the excavated foundation pit will also be filled, causing subsequent re-excavation, increasing construction cost

The invention discloses a pressurized spraying machine for the inner wall of a deep foundation pit of a building and a method for using the device. The middle position is vertically and fixedly connected with a hydraulic telescopic rod, the hydraulic telescopic rod is connected to a water tank, and a main electric telescopic rod is arranged below the water tank, and a rolling sleeve is connected to the main electric telescopic rod, and the upper end of the main electric telescopic rod A drive cylinder is provided. The main electric telescopic rod of the present invention rotates, so that the rolling sleeve rolls along the inner wall of the foundation pit, and the soil on the inner wall of the foundation pit is initially compacted. The upward movement occurs along the vertical guide rail, so that the driving cylinder pushes the small electric telescopic rod to slide along the horizontal guide rail to the inner wall of the foundation pit through the linkage rod, so that the impact block hits the inner wall of the foundation pit and further consolidates. The soil on the inner wall of the foundation pit.
Description
technical field [0001] The invention relates to the technical field of protection devices for building deep foundation pits, in particular to a pressurized spraying machine for inner walls of building deep foundation pits and a method for using the same. Background technique [0002] Deep foundation pit refers to a project whose excavation depth exceeds 5 meters (including 5 meters), or the depth does not exceed 5 meters, but the geological conditions, surrounding environment and underground pipelines are particularly complicated. The foundation pit project mainly includes the design of the foundation pit support system It is a highly comprehensive system engineering with construction and earthwork excavation; [0003] The deficiencies of the general construction deep foundation pit protection device are: after the general foundation pit is excavated, workers will be required to enter the foundation pit for construction operations, such as building some brackets and related ...
