Abstract
The utility model discloses a debris flow fast-discharging structure, which comprises a collecting tray and a fast-discharging tray. The collecting tray is of a trumpet shape upstream; the plan of the fast-discharging tray is a quadrangle, and the longitudinal section is a curve; the outlet end of the curve inclines inward, forming a trough valley the horizontal height of which is lower than the port of the outlet end. The utility model has the advantages of fast debris flow discharging, effective debris flow blocking prevention, abrasion resistance, and long service life.
Description
Technical field
The utility model relates to row's waveguide technology of mud-rock flow, especially relates to a kind of mud-rock flow quick draining structure.
Background technology
China is the country on mountain more than, and mud-stone flow disaster is extremely grown.Great development along with traffic technique, the highway mud-rock flow becomes the key issue of restriction highway construction, highway maintenance and communications and transportation day by day, suspended traffic 3-6 month individual month of the annual therefore disconnected road 1-3 of national highway 217 line Tianshan Mountains highways because of flowstone stream as national highway 318 lines (Sichuan-Tibet line) are annual.It is annual because the highway direct economic loss that mud-rock flow causes reaches hundred million yuan of 50-80.Therefore, both at home and abroad just carry out the research and the practice of debris flow drainage waveguide technology since nineteen seventies, developed mud-rock flow aqueduct, drainage groove.
Existing mud-rock flow aqueduct and drainage groove are identical on 26S Proteasome Structure and Function, and its planar graph is a rectangle, its vertical section be homogeneous than the oblique line that falls, its horizontal section has flat section and point two kinds in the section in the end.
The defective of existing mud-rock flow aqueduct and drainage groove is: one, it is near that debris flow body is gone out the throwing journey of arranging guide structure, generally promptly begin alluvial at the outlet position of row's guide structure, gradually the drainage groove that makes highway pass through the position silts up until the bridges and culverts silt is buried and damaged, and suspends traffic; Its two, existing debris flow drainage guide structure is easy to wear, application life is short, generally has only 2～3 years.
Summary of the invention
The purpose of this utility model provides a kind of can row fast and leads mud-rock flow, prevents that mud-rock flow silts up, anti abrasive mud-rock flow quick draining structure.The utility model is realized by following scheme: the mud-rock flow quick draining structure, constitute by collecting tray and fast chute, and described collecting tray is flare upstream; The plan view of described fast chute is a quadrangle, and its vertical section is a curve, and the port of export introversion of this curve forms the trough valley that a level height is lower than port of export port.
The horizontal section of described fast chute partly is made of rectangle top, trapezoidal middle part and curve bottom three, and its bottom curve is a circular curve.Quadrangle in the plan view of speed chute or be rectangle or is trapezoidal, and the downstream width of trapezoidal faces is less than upstream extremity.Vertical sectional curve of speed chute or be helical curve or is parabola, or is circular arc line, or be sinusoidal line, or is the cosine line, or is the string of a musical instrument anyway, or is the anticosine line, or is hyperbola, or is ellipse.Be laid with the build-in stake below the speed chute.
The utility model has the advantages that to arrange fast and lead mud-rock flow, prevent that effectively mud-rock flow silts up, wear-resistant, long service life.
Description of drawings
Fig. 1, Fig. 2 are plan view of the present utility model;
Fig. 3-Fig. 8 is vertical profile of the present utility model;
Fig. 9 is a transverse cross of the present utility model.
The specific embodiment
The mud-rock flow quick draining structure is made of collecting tray 1 and fast chute 2, and described collecting tray 1 is flare upstream; The plan view of described fast chute 2 is a quadrangle, and its vertical section is a curve, and the port of export of this curve forms the trough valley that a level height is lower than port of export port to updip.Because the port of export introversion of fast chute 2 makes mud-rock flow go out the throwing Cheng Yuan of row's guide structure, can the row's of causing guide structure silt up.Between craticular stage, trough valley can part be silted up by debris flow body at mud-rock flow, can play and reduce the effect of flowing water to the quick draining structure erosion.
The horizontal section of described fast chute 2 partly is made of rectangle top, trapezoidal middle part and curve bottom three, best results when bottom curve is circular curve, as shown in Figure 9.At mud-rock flow between active stage, the initial stage debris flow body silts up in bottom land curvature portion space, this part debris flow body is to flow than jogging speed, and most of debris flow body is in trapezoidal and rectangular cross section part flow at high speed, reduced the contact surface of debris flow body and fast chute 1 bottom, and then reached and reduce the rate of wear of debris flow body the debris flow drainage guide structure.At mud-rock flow between craticular stage, fast chute 2 bottom curvature portions can part be silted up by debris flow body, and the flowing water in the groove is at ordinary times flowed in the debris flow body that is deposited, and have reduced flow velocity, and then have weakened the erosion of flowing water for fast chute 2 bottoms.
Because at ordinary times flowing water weakens the wearing and tearing of quick draining structure in debris flow body and the groove, has prolonged the application life of quick draining structure, and reached about 15 years the application life of quick draining structure.
Quadrangle in the plan view of speed chute 2 can be rectangle, as shown in Figure 1; Also can be for trapezoidal, as shown in Figure 2.When trapezoidal, its downstream width is less than upstream extremity.
Vertical sectional curve of speed chute 2 can be helical curve, as shown in Figure 3; Also can be parabola, as shown in Figure 4; Or be circular arc line, as shown in Figure 5; Or be sinusoidal line, cosine line, the string of a musical instrument, anticosine line anyway, as shown in Figure 6; Or be hyperbola, as shown in Figure 7; Or be ellipse, as shown in Figure 8.
In order to strengthen the stability of mud-rock flow quick draining structure, can laying build-in stake 3 below fast chute 2.
