Temporary advance supporting construction equipment for tunnel

Abstract

The invention relates to temporary advance supporting construction equipment for a tunnel. The temporary advance supporting construction equipment comprises an adjusting device, a supporting bottom plate, a pipeline pushing device, a discharging device, a screw-thread pushing device, a screw-thread mounting device and a positioning device; the supporting bottom plate is mounted on the top of the adjusting device, the pipeline pushing device is mounted on the top of the left end of the supporting bottom plate, the discharging device is connected with the upper end face of the middle of the supporting bottom plate, and the screw-thread pushing device is located below the discharging device; and the screw-thread pushing device is mounted on the top of the supporting bottom plate, the screw-thread mounting device and the positioning device are connected with the top of the left end of the supporting bottom plate, and the screw-thread mounting device is located at the right end of the positioning device. According to the temporary advance supporting construction equipment, the difficult problems that during running casing through existing pipe roofing method construction, running casingfor drilled holes in different positions is conducted manually, positioning of a casing and a screw thread is conducted manually, connecting of the screw thread and the casing is conducted manually,the error of connecting between the casing and the screw thread is large, and the connecting difficulty of the casing and the screw thread is large can be solved.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a temporary advance support construction equipment for tunnels. Background technique [0002] The tube shed method construction or the umbrella arch method is an advanced support structure for shallow buried underground excavation of underground structural engineering. A steel pipe with a large moment of inertia is installed in the hole, which acts as a temporary advance support to prevent the soil layer from collapsing and surface subsidence, so as to ensure the safe operation of excavation and subsequent processes; As a new technology for tunneling in surrounding rocks, the pipe shed method was first used as an auxiliary method for tunnel construction. It played an important role in the construction of soft rock tunnels through broken zones, loose zones, and weak strata, and water and sand gushes. Because the pre-buried advanced pipe roof as roof and side wall supp...

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a temporary advance support construction equipment for tunnels, which can solve the problems of high labor intensity, dangerous manual operation, and manual drilling of holes in different positions when the existing pipe shed method is used to construct the casing. Carrying out the casing, manually positioning the casing and the threaded button, manually connecting the threaded button and the casing, the connection error between the casing and the threaded button is large, and the connection between the casing and the threaded button is difficult; the casing can be automatically Positioning and connection with threaded buttons, automatic feeding of threaded buttons, automatic positioning of threaded buttons and casings, and automatic casing loading of drilled holes at different positions. It has the functions of low labor intensity, no danger for automatic installation, and automatic adjustment. Casing for different drilling holes, automatic positioning of casing and threaded button, automatic connection of threaded button and casing, small connection error between casing and threaded button, and low difficulty in connecting casing and threaded button, etc.
