Description

Disaster prevention device for geological soft surface

Technical Field

The utility model relates to a geology weak face disaster prevention technical field, in particular to geology weak face's disaster prevention device.

Background

The geological weak surface is an unstable slope or rock mass threatening county cities, important towns and important public infrastructure, namely a weak surface of the rock mass or a joint surface, namely the stress weak surface refers to a surface which is easy to break and slide when stressed. Joints are a class of fracture structures, which refer to those where the rock cracks without significant relative displacement on either side of the fracture (as opposed to a fault with significant displacement). The conditioning is in fact a very common tectonic geological phenomenon. Colloquially, we are the cracks we see on rock outcrops. This is a fracture that occurs as a result of the rock being stressed, but no significant (as visually apparent) displacement occurs on either side of the fracture plane. Geologically, such fractures are called joints, which are seen everywhere on open rock. Rock mass with a joint surface is not harmful at present, but is likely to have the harmful phenomena such as slipping and the like along with the continuous time, so that the disaster prevention measures are required to be carried out in advance.

The anti-slip arm 3 includes a base 31, a lever 32, and a sliding arm 33. A loop bar 32 is obliquely fixed on the base 31, the base 31 and the loop bar 32 can be fixedly connected by welding or embedded connection, a sliding arm 33 is inserted in the loop bar 32, the sliding arm 33 can slide in the loop bar 32 relative to the loop bar 32, a shock absorbing spring 34 is arranged in the loop bar 32, two ends of the shock absorbing spring 34 are respectively fixedly connected with the bottom end of the loop bar 32 and one end of the sliding arm 33, and the base 31 is installed on the side wall of the main rock mass 1 and fixed through screws. The end of the sliding arm 33 remote from the loop bar 32 is fixed to the side wall of the sliding rock mass 2. The sliding arm 33 and the loop bar 32 are inclined in a direction parallel to the weak geological surface between the main rock body 1 and the sliding rock mass 2.

The loop bar 32 and the lateral wall of the sliding arm 33 are both provided with push plates 35, and when the sliding arm 33 slides in the loop bar 32, the two push plates 35 are constantly close to each other and contact with each other, a contact switch 36 is arranged between the two push plates 35, the contact switch 36 is arranged on the opposite surface of one of the push plates 35, the contact switch 36 is electrically connected with an external alarm, when the contact switch 36 is extruded, the external alarm is connected for power-on alarm, and the people around are warned, wherein the contact switch 36 is of an existing mechanical structure, and the using method and the mounting method thereof are common knowledge of the technical personnel in the field.

The device also comprises a holding and falling-preventing mechanism 4. The receiving anti-falling mechanism 4 comprises at least three groups of receiving columns 41, and in the embodiment, 4 groups of receiving columns 41 are arranged in a square shape. The containing net 42 is arranged above the four groups of containing columns 41, the top ends of the four groups of containing columns 41 are respectively connected with four corners of the containing net 42, and the containing net 42 is positioned on a sliding track of the sliding rock block 2.

Connect post 41 greatly includes the hollow post 411 of metal, pneumatic shock absorber rod 412, sliding connection piece 414, the hollow post 411 inner chamber of metal is provided with pneumatic shock absorber rod 412, rectangular breach 413 has been seted up to hollow post 411 one side of metal, pneumatic shock absorber rod 412 top is provided with sliding connection piece 414, sliding connection piece 414 one end is connected with the angle that connects net 42 greatly, its other end is connected with pneumatic shock absorber rod 412 top, sliding connection piece 414 can slide on rectangular breach 413, the hollow post 411 bottom of metal is provided with installation base 415. The mounting base 415 is fixed to the ground by screws.

Preferably, in this embodiment, the metal hollow column 411 may be inclined from bottom to top in a direction away from the receiving net 42, and an angle between the metal hollow column 411 and the ground is 85 degrees, so that the tension of the receiving net 42 in the process of pressure reduction is reduced as the sliding connection block 414 slides downwards and inwards, thereby effectively preventing the receiving net from being damaged.

In this embodiment, the connection relationship between the base 31 and the loop bar 32 is fixed, the surveying instrument is used to measure the position of the soft geological surface and the inclination angle thereof, and the anti-sliding support arm 3 with a proper angle corresponding to the position is manufactured after measurement, so that the angle of the anti-sliding support arm 3 does not need to be adjusted during use, and the effect of protecting the use method is achieved.

The use method of the device comprises the following steps:

1. and measuring the position of the geological weak surface and the inclination angle thereof by using a surveying instrument.

2. And moving the multiple groups of anti-sliding support arms 3 to the required positions, and keeping the arrangement direction of the sliding arms parallel to the geological weak plane between the main rock body 1 and the sliding rock block 2.

3. Fixing one end of the sliding arm 33 on the side wall of the sliding rock mass 2 by using mounting modes such as rivets, screws and the like, and mounting the base 31 on the side wall of the main rock mass 1;

4. and moving the containing anti-falling mechanism 4 to the sliding track of the sliding rock block 2, so that the lower ends of the four containing columns 41 are fixedly connected with the ground, and the four containing columns 41 incline outwards from bottom to top.

When the sliding rock 2 slides along the geological weak surface (joint surface) between the two, the sliding arm 33 is pushed by the pushing force to slide in the sleeve rod 32 to press the shock absorbing spring 34 to deform, so as to prevent the sliding rock 2 from sliding continuously. Thereby two sets of push pedal 35 can be constantly close and contact when the too big continuation gliding of sliding rock piece 2, contact switch 36 between two sets of push pedal 35 is triggered for rather than the external alarm circular telegram of intercommunication report to the police, warn crowd around. When the anti-skidding support arm 3 can not bear the heavier rock piece 2 that slides, the rock piece 2 that slides can fall down, fall on connecing the net 42 greatly, connect the net 42 greatly and receive four groups of sliding connection piece 414 of impulsive force downstream pulling on rectangular breach 413 downstream, thereby compress four groups of pneumatic shock absorber poles 412 contractions, the kinetic energy of rock piece 2 that will slide converts into the elastic potential energy of pneumatic shock absorber pole 412, play the effect of buffering shock attenuation, four groups of sliding connection piece 414 because the hollow post 411 of metal leans out from bottom to top when rectangular breach 413 downstream, and it is 85 degrees with the institute angle of ground, make the tension that falls down in-process and connect the net 42 greatly constantly reduce, prevent to lead to its damage owing to receiving too big impact force.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
