Technical Field
The utility model relates to a domatic type mud-rock flow retaining structure is applicable to mountain area mud-rock flow calamity prevention and cure.
Background
The slope type debris flow is a common mountain disaster excited by water sources such as heavy rain and the like, generally occurs in ecological fragile areas, is usually accompanied with collapse and landslide and contains a large amount of silt and stones. Because the slope type debris flow has the characteristics of difficult accurate identification, sudden occurrence and the like, once the slope type debris flow occurs, great economic loss and casualties can be caused. Along with the continuous extension and development of the current economic construction to mountainous areas, the influence of the slope type debris flow on the social development is larger and larger, and the effective prevention and treatment of the slope type debris flow become an important research subject.
According to long-term observation and test of debris flow in academic circles and research on various aspects such as formation mechanism, motion law, disaster mechanism and the like of the debris flow, the current debris flow prevention and treatment project generally adopts a comprehensive treatment mode combining stability, interception and drainage. The method is stable, and mainly aims to carry out ecological restoration, water and soil conservation and slope surface protection on the hillside and reduce debris flow sources; blocking, mainly taking blocking measures to the debris flow circulation area to reduce the flow and flow speed of the debris flow; and (4) under the two measures, the residual debris flow is subjected to drainage and guide measures, and drainage channels such as a river channel are introduced, so that the loss of debris flow to personnel and property at the ditch is avoided or reduced.
For debris flow blocking measures, currently, concrete dams or stone masonry dams are mainly adopted, but the following problems exist:
(1) the dam body and the foundation have large treatment engineering quantity, and the cost of concrete or masonry is high;
(2) for some areas with steep terrain, construction and traffic are inconvenient, and construction difficulty is high;
(3) the arrangement range of the blocking structure is large, and the engineering investment is large;
(4) because of the control investment, the general height of blocking structure is lower, leads to the storage capacity less on the one hand, influences the effect of blocking, and on the other hand, some rollings break through the blocking structure easily, cause the threat to lower part personnel, facility, equipment.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the shortcoming that exists among the prior art, provide a simple structure, construction convenience, cost are lower and block effectual slope type mud-rock flow retaining structure.
In order to realize the purpose, the utility model discloses a technical scheme as follows:
a slope type debris flow blocking structure comprises a protective net, a steel bar gabion, a pull rope and anchor rods; the protective net is arranged on a slope at the rear side of the protective area and arranged facing the direction of debris flow, and bases of the protective net are fixedly connected through bolts implanted into a stable foundation; the reinforcement gabion is stacked next to the rear side of the protective net in a step shape, and the anchor rod is implanted into a stable foundation on the front side of the protective net; one end of the pull rope is connected with the upper edge of the protective net and the other end of the pull rope is fixedly connected with the anchor rod.
Further, the reinforcing bar gabion welds each other as an organic whole and towards keeping away from the direction height of protection network reduces gradually.
Further, concrete is sprayed on the surface of the steel bar gabion for sealing.
Further, the protective net is perpendicular to the direction of the debris flow.
The technical scheme of the utility model, on one hand, the structure is simple and reliable, the blocking height of the protective net is high, the threat of the slope rolling stones and flying stones to the lower personnel and equipment can be effectively reduced, and the reinforcing steel bar gabion can assist the protective net to resist the impact of debris flow; and on the other hand, the construction is simple and convenient, the construction road arrangement and the construction equipment configuration can be greatly simplified, the construction difficulty and the investment can be reduced, and the construction equipment is quickly put into use. Meanwhile, the structure is convenient to maintain in the later period, and the damaged part of the protective net or the reinforced gabion can be quickly repaired or replaced.

Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Reference is made to the accompanying drawings. The retaining structure 1 of the present embodiment includes a protective net 2, a reinforcement gabion 3, a pulling rope 5, and an anchor bar 6. Wherein, blocking structure 1 wholly arranges on the protective area rear side slope, and protection network 2 sets up towards the mud-rock flow direction to play the effect of blocking to the mud-rock flow. Preferably, the protection net 2 is arranged perpendicular to the direction of the debris flow. The base of the protective net 2 is fixedly connected with a bolt 4 implanted into a stable foundation, and the reinforcement gabion 3 is stacked next to the rear side of the protective net 2 in a step shape. Specifically, reinforcing bar gabion 3 welds each other and highly reduces gradually for whole and towards the direction of keeping away from protection network 2 to supplementary effect of shocking resistance of strengthening the protection network 2, and for traditional structure 1 of blocking, can save the engineering investment greatly. Concrete is sprayed on the surface of the steel bar gabion 3 for sealing so as to prevent the steel bars from being corroded and improve the service life. And the combined structure of the protective net 2 and the reinforced gabion 3 can be better adapted to various topographic and geological conditions.

The implementation method of the embodiment comprises the following steps:
a. the debris flow retaining structure 1 is arranged at a position where the terrain and geological conditions on the slope surface are more suitable.
b. And constructing the bolt 4 and the anchor rod 6, and implanting the bolt 4 and the anchor rod 6 into the stable foundation.
c. A protective net 2 is installed, and a base of the protective net 2 is firmly connected with a bolt 4; the pull rope 5 of the protective net 2 is firmly connected with the anchor rod 6.
d. The reinforcing steel bar gabion 3 is processed in advance, after the protective screen 2 is installed, the reinforcing steel bar gabion 3 is stacked at the rear part of the protective screen 2, the reinforcing steel bar gabion 3 is welded into a whole, and concrete is sprayed on the surface of the reinforcing steel bar gabion 3 to seal the reinforcing steel bar gabion.
It should be noted that the above describes example embodiments of the invention. However, it should be understood by those skilled in the art that the present invention is not limited to the above-described embodiments, which are only illustrative of the principles of the present invention, and that various changes and modifications may be made without departing from the scope of the present invention, and the changes and modifications are intended to fall within the scope of the present invention as claimed.
