Abstract
The invention discloses a spillway chute base board covered drainage system, which comprises an under-board permeable pipe arranged under the chute base board and along a longitudinal central line of the chute base board, under-platform permeable pipes respectively arranged at the bottoms of retaining wall base platforms on the two sides of the chute base board along a longitudinal direction, and a behind-wall drainage system; the under-board permeable pipe is communicated with the under-platform permeable pipes through transverse permeable pipes which incline towards the downstream direction and are arranged at interval on the two sides of the under-platform permeable pipes along a longitudinal direction; slope permeable pipes communicated with under-platform permeable pipes are respectively arranged along first grade excavation slopes of the retaining wall base platforms on the two sides of the chute base board; and the behind-wall drainage system is composed of a longitudinal plastic permeable blind pipe, vertical plastic permeable blind pipes and horizontal blind pipes which are communicated. The spillway chute base board covered drainage system has the advantages that the transverse permeable pipes fully use a gradient of the chute base board to form a natural drainage gradient, accordingly, the project amount is small; and the under-board permeable pipe and the transverse permeable pipes form a 'fishbone-shaped' net arrangement, so that reliability of the drainage system is improved.
Description
Technical field
Flood spillway when the present invention relates to phreatic high is let out groove, especially relates to flood spillway and lets out the dark drainage system of trough floor.
Background technology
It is to sew cloth and put the permeable gutter of vertical, horizontal orthorhombic form along letting out the trough floor plate that flood spillway is let out the conventional way of the dark drainage system of trough floor, and form of structure has polytypes such as grooved precast unit, non-fine concrete band, flexible water-permeable pipe.But adopt orthorhombic form to arrange and have following defective: 1, take usually and let out the identical gradient of trough floor along letting out permeable gutter that the trough floor longitudinal midline arranges, this just makes horizontal permeable gutter to form certain draining gradient through the excavation elevation; Simultaneously, longitudinally be arranged in let out the trough floor both sides permeable gutter elevation also in requisition for reduction, thereby the section that causes slotting strengthens and the transverse drainage section is a gradual change type, excavated volume is big and construct loaded down with trivial details.2, the permeable gutter quadrature of vertical, horizontal has influenced the current effect that crosses, and the flip-flop of infall water (flow) direction is easy to cause and locally becomes silted up stifledly, and the long-time running interface will take place by spilling water destruction, influence the safe operation that flood spillway is let out groove.
Summary of the invention
The object of the invention is to provide a kind of easy construction, engineering quantity flood spillway little, that effectively improve the draining reliability to let out the dark drainage system of trough floor.
For overcoming the above problems, the present invention takes following technical proposals:
Flood spillway of the present invention is let out the dark drainage system of trough floor; Comprise by straightway, abrupt slope section, choose the trough floor of letting out that the bank section constitutes; Along letting out water-permeable pipe under the trough floor longitudinal midline setting plate thereunder; Longitudinally be separately positioned on water-permeable pipe under the platform of letting out trough floor two lateral retaining wall base stations bottoms, and be separately positioned on drainage system behind the wall of letting out the trough floor two lateral retaining walls outside; Under the said plate water-permeable pipe respectively under a plurality of horizontal water-permeable pipe through longitudinally being arranged at interval its both sides and the said platform water-permeable pipe be connected; Said a plurality of horizontal water-permeable pipe all and under the plate between the water-permeable pipe with 56 °～60 ° angles towards downstream direction be obliquely installed; One-level excavation slope along letting out trough floor two lateral retaining wall base stations is arranged at intervals with the slope water-permeable pipe that water-permeable pipe is connected under a plurality of with the corresponding platform respectively; Behind the said wall drainage system by: a plurality of upright to the plastics Permeable blind pipe, be arranged on a plurality of horizontal plastics Permeable blind pipe formation on the barricade base station table top along what let out that vertical plastics Permeable blind pipe, perpendicular separation that trough floor vertically is arranged on barricade base station and barricade outer wall junction be arranged on the barricade outer wall along letting out the trough floor spaced radial; Said a plurality of standing all is connected with said vertical plastics Permeable blind pipe to plastics Permeable blind pipe, horizontal plastics Permeable blind pipe; Let out trough floor and choose to be horizontally arranged with below the bank section and choose bank section water-permeable pipe being positioned at, said two-port of choosing bank section water-permeable pipe respectively with corresponding platform under water-permeable pipe be connected.
Said standing to plastics Permeable blind pipe, horizontal plastics Permeable blind pipe, vertical plastics Permeable blind pipe is the hollow, rectangular structure; Water-permeable pipe under water-permeable pipe, the platform under the said plate, laterally water-permeable pipe, slope water-permeable pipe are flexible water-permeable pipe.
Advantage of the present invention is mainly reflected in:
1, the horizontal water-permeable pipe of oblique layout can make full use of and let out the trough floor gradient, adopts unified section, forms the natural drainage gradient, easy construction, and engineering quantity is little.
2, water-permeable pipe and a plurality of horizontal water-permeable pipe constitute " fishbone type " netted layout under the said plate; Make that letting out the dark draining of trough floor forms complete sealing drainage system, current are pooled to water-permeable pipe under the platform through the horizontal water-permeable pipe of intensive oblique layout, and vertical, horizontal water-permeable pipe interpenetrates; And be interconnected into drainage system with the bank section water-permeable pipe of choosing along lateral arrangement; Will the row of infiltration downstream, the draining stream is more unobstructed, has effectively improved the reliability of drainage system.
3, be arranged on let out the trough floor two lateral retaining walls outsides broach shape wall after drainage system, solved the seepage problem in banketing in the barricade outside; Water percolating capacity is bigger in owing to banket, and should not discharge along foundation of wall, but the elevation that bankets behind the barricade discharges at the face low level that bankets, the side direction that has made full use of hollow, rectangular plastics blind pipes catchment ability strong, bear the big characteristics of pressure.
4, the slope water-permeable pipe that is provided with at interval along the one-level excavation slope of letting out trough floor two lateral retaining wall base stations with longitudinally be arranged on the drainage system that water-permeable pipe under the platform of letting out trough floor two lateral retaining wall base stations bottom forms rock mass behind the complete wall.
