Abstract
The utility model provides a dangerous rock rockfall initiative bootstrap system to effectively avoid the protection network to pile up because of dangerous rock rockfall and cause the clearance difficulty, avoid rockfall to strike protection network inefficacy and avoid appearing the rockfall risk in the operation when ability is big. The method comprises the following steps: the curtain type net for energy dissipation and buffering of the dangerous falling rocks covers the rolling range of the dangerous falling rocks, and the curtain type net is fixed on the stable slope surface by the aid of the distributed anchor rods; the transverse guide ditches are arranged on the slope surface of the stable side slope between the line and the dangerous rock falling rocks at intervals, and two sides of each transverse guide ditch extend to the side of the back hill.
Description
Technical Field
The utility model relates to a geotechnical engineering, in particular to dangerous rock rockfall initiative bootstrap system.
Technical Field
At present, the dangerous rock rockfall engineering prevention and control generally adopts a completely-cleaned or constructed protective net, and the protective net is divided into an active net and a passive net based on the design concept of 'blocking' for rockfall. If the active net is adopted for protection, dangerous rocks and rockfall are accumulated to cause the problem of 'belly bulging', the cleaning is difficult, and rockfall risks exist in the operation; if adopt passive net protection, have when falling rocks impact energy big passive net inefficacy, have the problem such as falling rocks risk in the operation. Curtain type net is a protection network that provides based on the design theory of "dredging", but present curtain type net can't control the rockfall orbit, and the rockfall is amassed on curb or platform, if the rockfall is more, easily encroaches on lane or the road bed face, threatens train operation safety.
Therefore, there is a need to develop an active guidance system for dangerous falling rocks, which can effectively solve the existing problems, and has the characteristics of safety, economy, convenience in construction and the like.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a dangerous rock rockfall initiative bootstrap system is provided to effectively avoid the protection network to pile up because of dangerous rock rockfall and cause the clearance difficulty, avoid rockfall impact energy to lose efficacy and avoid appearing the rockfall risk in the operation in the protection network in big time.
The utility model provides a technical scheme that existing above-mentioned technique adopted as follows:
the utility model relates to a dangerous rock rockfall initiative bootstrap system, characterized by includes: the curtain type net for energy dissipation and buffering of the dangerous falling rocks covers the rolling range of the dangerous falling rocks, and the curtain type net is fixed on the stable slope surface by the aid of the distributed anchor rods; the transverse guide ditches are arranged on the slope surface of the stable side slope between the line and the dangerous rock falling rocks at intervals, and two sides of each transverse guide ditch extend to the side of the back hill.
The beneficial effects of the utility model are that, adopt horizontal guide ditch and curtain formula network system, the curtain formula net subducts the energy of falling rocks, can only roll to horizontal guide ditch along domatic, utilizes the longitudinal gradient of horizontal guide ditch and the residual energy of falling rocks, will fall rocks and guide to the back of the body mountain side. The problems that cleaning is difficult, the protective screen fails when rockfall impact energy is high, rockfall risks exist in operation and the like caused by 'belly bulging' of a traditional protective screen are effectively solved, and the protective screen has the advantages of being safe, reliable, convenient to construct, saving in investment and the like, and is wide in application prospect.
Drawings
The specification includes the following three drawings:
FIG. 1 is a cross-sectional view of a conventional curtain web arrangement;
fig. 2 is a cross-sectional view of the arrangement of the active guidance system for dangerous falling rocks of the present invention;
fig. 3 is a plan view of the arrangement of the active guidance system for dangerous falling rocks of the present invention.
The names and corresponding labels of the main components are shown in the figure: curtain type net 1, stock 2, horizontal guide ditch 3, circuit A, stable slope face B, dangerous rock falling rock C, back of the body mountain side P.
Detailed Description
The invention will be further described by means of specific embodiments and with reference to the accompanying drawings.
Referring to fig. 2 and 3, the utility model relates to a dangerous rock rockfall initiative bootstrap system, include: the curtain type rockfall protection device comprises a curtain type net 1 and anchor rods 2, wherein the curtain type net 1 which performs energy dissipation and buffering on the dangerous rockfall C covers the rolling range of the dangerous rockfall C, and the curtain type net 1 is fixed on a stable slope surface B by the aid of the anchor rods 2 which are distributed; and the transverse guide ditches 3 are arranged on the stable slope surface B between the line A and the dangerous rock falling rocks C at intervals, and two sides of each transverse guide ditch 3 extend to the back hill side P. The curtain type net 1 reduces the energy of the dangerous rock falling rocks C, can only roll to the transverse guide ditch 3 along the slope surface B of the stable side slope, and guides the dangerous rock falling rocks C to the back mountain side P by utilizing the longitudinal slope of the transverse guide ditch 3 and the residual energy of the falling rocks. The problems that cleaning is difficult, the protective screen fails when rockfall impact energy is high, rockfall risks exist in operation and the like caused by 'belly bulging' of a traditional protective screen are effectively solved, and the protective screen has the advantages of being safe, reliable, convenient to construct, saving in investment and the like, and is wide in application prospect.
Referring to fig. 3, the anchor rods 2 are arranged on the stable slope surface B at equal intervals, and the anchor rods 2 should determine the anchoring depth according to the uplift resistance. The transverse guide ditch 3 has a certain longitudinal slope towards the back mountain side P and plays a role in guiding the dangerous rock falling rocks C to roll. The size of the cross section of the transverse guide ditch 3 is comprehensively determined by the diameter of the dangerous rock falling rocks C, the slope of the stable slope surface B, the height of the dangerous rock falling rocks C and the like.
Referring to fig. 2 and 3, the utility model discloses a dangerous rock falling rock initiative bootstrap system is under construction according to following step:
firstly, manually slotting and constructing a plurality of guide ditches 3 on a natural slope surface B, and connecting the guide ditches 3 at two sides to the back side of a mountain;
secondly, a curtain type net 1 is laid in the range of dangerous rock falling rocks C, and an anchor rod 2 is adopted to be fixed on a natural slope surface B.
The above description is only used for illustrating the present invention, but not to limit the present invention to the specific structure and application range shown and described, so that all the corresponding modifications and equivalents that may be utilized all belong to the claimed patent scope of the present invention.
