[0003] During the construction of the tunnel, it is necessary to install protective materials such as waterproof boards and geotextiles on the surrounding rock. The distance between the surrounding rock and the ground is relatively large, and it depends on the auxiliary operation of the trolley, which is dangerous and low in efficiency; The current protective material auxiliary installation equipment adopts the scheme of arc-shaped track and sliding trolley, and uses the movement of the trolley to install protective materials at multiple positions; because the track and the shape of the surrounding rock cannot adapt, the position of the lower platform needs to be adjusted. The protective material is pre-tensioned and manually assisted to push the protective material to fit the surrounding rock. The entire working process still requires manual close cooperation. For flexible protective materials, it is difficult to achieve a good fit between the protective material and the surrounding rock. Meet the protection needs of surrounding rock

Embodiment 1
[0034] In a typical embodiment of the present disclosure, such as Figure 1-Figure 5 As shown, a tunnel surrounding rock protection material installation device is given.
[0035] During the construction of the tunnel, it is necessary to lay and install waterproof boards, geotextiles and other protective materials 3 to meet the quality, maintenance and service life requirements of the tunnel. The material of the waterproof board is heavy, and it requires workers to manually transport it to the trolley 1, spread it, and shoot nails to anchor it. The labor intensity is high. In addition, the temperature in the tunnel is high and the construction environment is poor, which will greatly increase the labor burden of the workers. There are many unsafe factors. For the laying of geotextiles, the overall is relatively soft, and it is difficult to maintain the fit between the geotextiles and the surrounding rock during the laying process.
[0036] In view of the above problems, the tu...
Embodiment 2
[0067] In another embodiment of the present disclosure, as Figure 1-Figure 5 As shown, a method for installing tunnel surrounding rock protection materials is given.
[0068] Utilize the tunnel surrounding rock protection material installation device as in embodiment 1, carry out the installation of tunnel surrounding rock protection material 3, comprise the following steps:
[0069] Cover the protective material 3 on the sweeping surface of the support plate 2 and flatten it;
[0070] Rotate and extend the support plate 2, so that a plurality of support plates 2 form an umbrella-shaped support for the protective material 3;
[0071] The protective material 3 preferentially contacts the top surface of the surrounding rock, and the support plate 2 swings;
[0072] The protective material 3 is gradually scraped off from the middle to both sides by the sweeping surface, so that the protective material 3 fits the surrounding rock.
[0073] When installing flexible protective m...

Abstract
The invention provides a tunnel surrounding rock protection material installation device and method, and relates to the field of surrounding rock construction equipment. Aiming at the problem that an existing surrounding rock protection material auxiliary installation device cannot make a protection material attached to surrounding rock easily, a plurality of telescopic supporting plates doing swing actions are arranged to support and tension the protection material in advance, after the protection material is pushed to make contact with the surrounding rock, the flexible protection material can be scraped through a sweeping face, the protection material is attached to the surrounding rock, and the protection requirement is met. The device comprises a movable platform and the telescopic supporting plates, wherein one side edge of each supporting plate is rotationally installed on the movable platform, and the axes of rotating shafts of all the supporting plates are parallel; the sweeping face is arranged at the ends, away from the axes of the rotating shafts, of the supporting plates, and the supporting plates can change the distance between the sweeping face and the axes of the rotating shafts through stretching and contracting; the supporting plates are connected with swing driving mechanisms, and the supporting plates can be driven to swing around the axes of the rotating shafts in a reciprocating mode.
Description
technical field [0001] The present disclosure relates to the field of surrounding rock construction equipment, in particular to a device and method for installing tunnel surrounding rock protection materials. Background technique [0002] In the infrastructure construction process such as railways and highways, tunnel engineering construction is relatively common. Among them, the surrounding rock needs to be protected after the surrounding rock is exposed by excavation. [0003] During the construction of the tunnel, it is necessary to install protective materials such as waterproof boards and geotextiles on the surrounding rock. The distance between the surrounding rock and the ground is relatively large, and it depends on the auxiliary operation of the trolley, which is dangerous and low in efficiency; The current protective material auxiliary installation equipment adopts the scheme of arc-shaped track and sliding trolley, and uses the movement of the trolley to install p...
