Problems solved by technology
[0003] Nowadays, the method of perforating and grouting treatment at home and abroad is mainly to vertically perforate and grout the surface of the subgrade and then seal the hole, but the defect of this is that the route must be blocked for a period of time, which will definitely bring inconvenience to the passing traffic and bring great inconvenience to the owner. Large loss, and because the cavity at the bottom of the slab may be connected to the slope, it is not easy to form a pressure difference during vertical drilling and grouting, which will easily lead to incomplete filling and affect the grouting effect

The invention discloses equipment for conducting drilling and grouting through a roadbed slope and belongs to the technical field of road and bridge maintenance. The equipment comprises a vehicle frame. The vehicle frame is provided with a drilling system. The drilling system comprises a top pipe and a drill stem arranged in the top pipe in a sleeved manner. The vehicle frame is further provided with a hydraulic propelling system which provides propelling force for the top pipe and the drill stem and pushes the top pipe and the drill stem to penetrate into a soil body. The equipment has the beneficial effects of being easy to operate, convenient to use, integrated in function and capable of conducting drilling and grouting at different positions and angles.
Description
technical field [0001] The invention belongs to the field of highway and bridge maintenance, and in particular relates to a device for drilling and grouting from roadbed side slopes. Background technique [0002] Nowadays, the number of expressways is increasing day by day, and some highway and bridge diseases are also becoming more and more obvious. In the actual operation process, we found that part of the abutment board was broken, which caused the bridge head to jump too violently, seriously endangering the driving safety and driving quality, and effective measures must be taken to deal with it. The main reason for the breakage of part of the abutment slab is that the connection between the abutment and the subgrade has settled too much after the construction of the subgrade, and there is a hollow phenomenon at the bottom of the slab, which causes the slab to break under various loads. At present, the main treatment method for the excessive settlement of the subgrade an...
