Abstract
The invention discloses a drainage structure of an excavation slope of a plunge pool. The drainage structure comprises a plunge pool slope, a bottom plate, a plurality of longitudinal drainage ditches and a plurality of transverse drainage ditches; the plunge pool slope and the bottom plate are of concrete structures; the longitudinal drainage ditches are longitudinally arranged under the bottom plate; the transverse drainage ditches are arranged under the bottom plate at longitudinal intervals of 12 meters; the transverse drainage ditches are respectively communicated with the longitudinal drainage ditches which are crossed with the transverse drainage ditches; the longitudinal drainage ditches positioned on two sides of the bottom plate are communicated with rectangular plastic blind ditches which are vertically arranged under the plunge pool slope along the plunge pool slope; four groups of communicating holes are arranged at the upper end of each rectangular plastic blind ditch from top to bottom at intervals of 4 meters; each group of communicating holes consists of 2 through holes; and each through hole is communicated with a corresponding drainage hole through a plastic blind tube, and each drainage hole is upwards obliquely arranged on the slope at an angle of 10 degrees. The drainage structure has the advantages that the drainage holes arranged on the rock slope of the plunge pool are communicated with the rectangular plastic blind ditches to form a systematic drainage network, reverse water pressure on a reinforced concrete slope is greatly reduced, and the stability of the reinforced concrete slope is improved.
Description
Technical field
The present invention relates to the cushion pool excavation slope, especially relate to the discharge structure of cushion pool excavation slope.
Background technology
In hydraulic engineering, adopt the excavation slope of concrete slab protection usually need adopt drainage pattern at the back side of panel, reduce the back side phreatic line of panel, in the hope of reducing the reverse water pressure power that panel bears, improve the stable condition of panel.For panel can perforate structure, the water of rock mass drain hole can directly be discharged through the gutter on the panel; For the structure that panel can not be established gutter, the drainage network of the system of then need setting up departments at the back side of panel, measure commonly used has gutter, gutter etc.
Summary of the invention
The object of the invention is to provide a kind of discharge structure of cushion pool excavation slope, to realize effectively reducing the groundwater table after the steel concrete side slope, guarantees the safe in utilization of steel concrete side slope.
For realizing above-mentioned purpose, the present invention takes following technical proposals:
The discharge structure of cushion pool excavation slope according to the invention; The cushion pool side slope and the base plate that comprise reinforced concrete structure; Longitudinally be arranged on many longitudinal drainage ditches below the said base plate; Longitudinally at interval 10-12 rice is arranged on many transverse drain ditch below the base plate, and said transverse drain ditch is connected with the longitudinal drainage ditch that intersects respectively; Being positioned at the longitudinal drainage ditch of base plate two avris is connected with rectangular plastic french drain below the cushion pool side slope vertically is arranged on the cushion pool side slope; In the upper end of said every rectangular plastic french drain from top to bottom at interval 2-4 rice offer at least four group intercommunicating pores; Every group of intercommunicating pore is made up of 2-3 through hole, and said each through hole is connected with the 8-10 ° of drain hole that is opened on the cushion pool rock side slope that be inclined upwardly through the plastics blind pipe respectively.
The drain hole diameter that is opened on the said cushion pool rock side slope is the 30-60 millimeter, hole depth 8-12 rice.
The invention has the advantages that said rectangular plastic french drain has the out-of-flatness, the assembled on site that the adapt to excavation slope characteristics simply and easily of constructing; With being opened in drain hole on the said cushion pool rock side slope formation system drainage network that is connected with the rectangular plastic french drain; Greatly reduce the reverse water pressure power of steel concrete side slope, improved the stability of steel concrete side slope.

The specific embodiment
Shown in Fig. 1-4; The discharge structure of cushion pool excavation slope according to the invention; The cushion pool side slope 1 and base plate 2 that comprise reinforced concrete structure; Longitudinally be arranged on five longitudinal drainage ditches 3 and 12 meters many transverse drain ditch 4 that are arranged on below the base plate 2 at interval longitudinally below the said base plate 2, said every transverse drain ditch 4 is connected with every longitudinal drainage ditch 3 that it intersects respectively; Being positioned at the longitudinal drainage ditch 3 of 2 liang of avris of base plate is connected with rectangular plastic french drain 5 below cushion pool side slope 1 vertically is arranged on cushion pool side slope 1; Upper end at said every rectangular plastic french drain 5 offers four groups of intercommunicating pores for 3 meters in the interval from top to bottom; Said every group of intercommunicating pore is made up of 2 through holes; Each through hole is connected with the drain hole 8 that is opened on the cushion pool rock side slope 7 that is inclined upwardly 10 ° through round plastic blind pipe 6 respectively; The diameter of said drain hole 8 is 50 millimeters, 10 meters of hole depths.
Stop up rectangular plastic french drain 5 when avoiding concreting, after round plastic blind pipe 6 and 5 assemblings of rectangular plastic french drain, wrap up one deck geotextiles again; Cause moving of rectangular plastic french drain 5 when avoiding concreting, adopt iron sheet and cement nail that rectangular plastic french drain 5 is fixed on the cushion pool rock side slope 7.
