Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a kind of excavation construction equipment for tunnels with weak surrounding rocks, which can solve the problems of heavy labor and the need for manual removal of pinch plates and clamping plates when the existing pipe shed method is used to connect U-shaped steel and support steel. , Unable to automatically position and place the clamping plate and buckle plate, unable to control the positioning and placement of the nut, the nut is easy to fall when taking it, the bolt cannot be automatically controlled for positioning and installation, and the positioning of the bolt and nut will be deviated during installation, resulting in difficulty in the installation of the bolt and nut and other difficult problems; it can realize the automatic blanking of bolts, the automatic positioning of the pinch plate and the clamping plate in the construction of the pipe shed method, and the function of fixing the pinch plate and the clamping plate through the cooperation of bolts and nuts. Automatic push, automatic positioning and placement of the clamping plate and the buckle plate, automatic control of the positioning and placement of the nut, the nut will not fall during positioning, automatic control of the positioning and installation of the bolt, and no positioning deviation during the installation of the bolt and nut, etc.

Abstract

The invention relates to weak surrounding rock tunneling construction equipment. The weak surrounding rock tunneling construction equipment comprises a supporting bottom plate, traveling wheels, a clamping plate mounting device, a buckle plate mounting device and a feeding device. The supporting bottom plate is provided with a square groove, traveling wheels are symmetrically mounted on the bottomof the supporting bottom plate, the clamping plate mounting device is arranged on the right side of the square groove in the supporting bottom plate in a distributed mode, the buckle plate mounting device is arranged on the left side of the square groove in the supporting bottom plate in a distributed mode, the clamping plate mounting device and the buckle plate mounting device are both mounted on the supporting bottom plate, and the feeding device is mounted on the buckle plate mounting device. The weak surrounding rock tunneling construction equipment can solve the existing problems that when a U-shaped steel is connected with a supporting steel by adopting an existing pipe shed method, a buckle plate and a clamping plate need to be manually taken, the clamping plate and the buckle plate cannot be automatically positioned and placed, nuts cannot be controlled for positioning and placing, and the nuts are prone to dropping when taking, bolts cannot be automatically controlled for thepositioning and installation, and deviations of positioning for the bolts and nuts occurs when installing.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to tunnel excavation construction equipment for weak surrounding rock. 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 shed as roof and side wall ...
