Technical Field
The invention relates to the technical field of rope saw cutting, in particular to a method for cutting and dismantling a supporting beam of a foundation pit support by using a rope saw.
Background
In recent years, along with the high-speed development and the increase of population density of cities, urban buildings are continuously developed towards high and deep two sides, high-rise buildings become the main melody of urban construction, corresponding to the matched establishment of multi-layer basements, underground tunnels, subways, commercial streets and the like, so that projects to be built are often adjacent to the high-rise buildings, underground structures and the like, the use of a foundation pit anchor rod and anchor cable support system is limited due to the complexity of the surrounding environment of the buildings, and the support system of 'support piles or continuous walls and inner supports' is widely applied in recent years instead, particularly, reinforced concrete inner supports are mainly used, and the stability of deep foundation pits is greatly improved. And as the depth of the ground increases, the number of layers of the inner support also increases from one layer of support to multiple layers of support.
Common foundation pit support beam dismantling methods include gunpowder blasting dismantling, mechanical dismantling, manual dismantling and the like. As the temporary supporting structure is mostly located in urban downtown areas, the periphery or buildings are dense, or the subway is operated nearby, the temporary supporting structure is dismantled without causing adverse effects on a temporary supporting system, peripheral buildings and underground facilities. When the multi-layer inner supporting beam is dismantled, a constructed underground horizontal structure is often used as a construction platform, so that higher challenges are provided for the dismantling method.
In the prior art, for example, the patent of the invention in China with the publication number of CN103510523B discloses a method for integrally lifting a deep foundation pit multilayer reinforced concrete inner support beam by section cutting, which comprises the steps of internal force monitoring, cutting and dismantling, foundation pit inner transfer, support beam integral lifting, support beam off-site crushing and the like.
The invention is constructed on the underground horizontal thin plate structure, has no special requirement on a construction platform, does not need to strengthen the underground thin plate structure steel pipe supporting system, and only needs to locally strengthen the reserved hole and the reserved expansion joint of the underground horizontal thin plate. And when the supporting beam is cut and removed, the lower part does not need to be provided with a steel pipe bracket. The one-time input amount of the on-site steel pipe support material is greatly reduced, and the steel pipe support can be dismantled in advance to improve the turnover rate of the steel pipe support.
The above prior art solutions have the following drawbacks: the staff passes through the in-process of rope saw cutting, the water cooling that needs go on high-speed moving diamond rope to take away the piece of grinding through rivers, but, because a supporting beam is on fender pile or the continuous wall that horizontal anchor is in, consequently lead to the cooling water in the cooling process, the cooling water runs off in a large number, and it is great to retrieve the degree of difficulty, and the difficult recycling of cooling water is comparatively serious water waste.
