Embodiment Construction
[0036] The specific implementation manner of the present invention will be described in more detail below with reference to schematic diagrams. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.
[0037] As mentioned in the background technology, obstacles containing steel bars and steel materials are one of the most difficult objects to remove during the construction of underground projects. There are other immovable structures above the object, making it difficult to remove the obstacle.
[0038] Therefore, in order to solve the above problems during underground engineering construction, the present invention provides a method for removing underground obstacles.
[0039] refer to figure 1 , which is a...

The invention provides a method for removing an underground obstacle. The method for removing the underground obstacle comprises the following steps that a working well is formed, the area where the obstacle needs to be cleared is positioned on the side wall of the working well; the area where the obstacle needs to be cleared is divided into a plurality of regions, working is carried out on the regions in a first direction form boreholes, fillers are injected into the boreholes, and an included angle exists between the first direction and the height direction of the working well; and the areaof the space surrounded by all the boreholes is cut to form a tunnel. According to the method for removing the underground obstacle, the area where the obstacle needs to be cleared is divided into a plurality of regions, in the obstacle removing process, the obstacle is removed in a partition mode, the construction area is not prone to collapsing, the danger of workers in work is reduced, holes are drilled in the horizontal direction under the ground, safety and reliability are achieved, environmental impact is small, high work efficiency is achieved, speediness and economy are achieved, energy is saved, and environmental protection is achieved.
Description
technical field [0001] The invention relates to the technical field of underground engineering construction, in particular to a method for removing underground obstacles. Background technique [0002] For underground engineering, if a large and hard underground obstacle is detected, sometimes it is necessary to change the design plan or even plan, which is generally difficult to do, and all aspects hope to solve it through advanced construction technology; among them, radar detection, advance Processing, the workload is heavy, and obstacles cannot be removed directly; direct excavation is suitable for the outer suburbs, and the surrounding environment is not demanding, and it is not suitable for most of the current municipal underground engineering projects located in the bustling downtown; generally, vertical obstacle removal by ground drilling rigs will also be considered , but if the vertical clearance of the ground does not meet the conditions, for example, the ground sp...
