Method of cutting and detaching supporting beam for retaining and protection of foundation pit by means of rope saw

Abstract

The invention relates to a method of cutting and detaching a supporting beam for retaining and protection of a foundation pit by means of a rope saw. The method includes the steps of drawing cutting lines, supporting up the supporting beam, detecting internal force, performing cutting and detaching, performing transferring in the foundation pit, breaking the supporting beam off site and the like.In the process of cutting and detaching the supporting beam, the supporting beam is cut through a diamond cutting device, the diamond cutting device comprises a diamond rope and a driving motor for driving the diamond rope to perform cutting, the diamond cutting device further comprises a wrapping assembly, the diamond rope is wound around the edge of a cut face of the supporting beam, the wrapping assembly wraps the edge of the cut face of the supporting beam, and the wrapping assembly comprises an open water collecting tank, and a negative pressure pipe and a water inlet pipe which communicate with the water collecting tank. The method has the advantages that cold water and grinding debris are mixed and accumulated in the water collecting tank, the negative pressure pipe communicating with the water collecting tank pumps out and recovers the cold water mixed with the grinding debris, and water resources are less wasted.

Description

technical field [0001] The invention relates to the technical field of wire saw cutting, in particular to a wire saw cutting and removing method for foundation pit support support beams. Background technique [0002] In recent years, with the rapid development of cities and the growth of population density, urban buildings have been developing towards high and deep. High-rise buildings have become the main theme of urban construction. The engineering is often adjacent to high-rise buildings or underground structures, etc. The complexity of the surrounding environment of the building restricts the use of anchor bolt and cable support systems for foundation pits. It has been widely used, especially in reinforced concrete inner support, which greatly improves the stability of deep foundation pits. And as the underground depth increases, the number of layers of inner support also increases from one-layer support to multi-layer support. [0003] Commonly used demolition methods...

AI Technical Summary

Problems solved by technology

[0006] The above existing technical solutions have the following defects: in the process of cutting by the wire saw, the workers need to cool the high-speed diamond rope with water, and the abrasive debris will be taken away by the water flow. However, since the support beam is horizontal Horizontally anchored on the support pile or continuous wall, so the cooling water will be lost in a large amount during the cooling process, it is difficult to recycle, the cooling water is not easy to recycle, and the waste of water resources is serious
