Abstract
The utility model discloses a water-draining structure of a plunge pool excavation slope. The water-draining structure of the plunge pool excavation slope comprises a plunge pool slope and a bottom plate which are of a concrete structure, a plurality of longitudinal water-draining ditches which are arranged on the lower face of the bottom plate longitudinally and a plurality of horizontal water-draining ditches which are arranged on the lower face of the bottom plate longitudinally at intervals of 12 meters. The horizontal water-draining ditches are respectively communicated with the longitudinal water-draining ditches. The longitudinal water-draining ditches placed on two sides of the bottom plate are communicated with rectangle-shaped plastic blind ditches which are arranged vertically along the plunge pool slope and placed below the plunge pool slope. Four groups of communication holes are arranged in the upper end of each rectangle-shaped plastic blind ditch from top to bottom at intervals of 4 meters. Each group of communication holes comprises two through holes. Each through hole is communicated with a water-draining hole which is arranged inclining upwards 10 degrees in the slope through a plastic blind pipe. The water-draining structure of the plunge pool excavation slope has the advantages that the water-draining holes arranged in the plunge pool slope rocky slope are communicated with the rectangle-shaped plastic blind ditches so that a system water-draining network is formed, the reverse water pressure of a reinforced concrete slope is greatly lowered, and the stability of the reinforced concrete slope is improved.
Description
Technical field
The utility model relates to the cushion pool excavation slope, especially relates to the discharge structure of cushion pool excavation slope.
Background technology
In hydraulic engineering, adopt the excavation slope of concrete slab protection usually need to adopt drainage pattern at the back side of panel, reduce the back side phreatic line of panel, to the reverse water pressure power that the reduction panel bears, improve the stable condition of panel.For panel can perforate structure, the water of rock mass drain hole can directly be discharged by the gutter on the panel; Can not establish the structure of gutter for panel, the drainage network of the system of then need to setting up departments at the back side of panel, measure commonly used has gutter, gutter etc.
Summary of the invention
The utility model purpose 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 use safety of steel concrete side slope.
For achieving the above object, the utility model is taked following technical proposals:
The discharge structure of cushion pool excavation slope described in the utility model, the cushion pool side slope and the base plate that comprise reinforced concrete structure, longitudinally be arranged on many longitudinal drainage ditches below the described base plate, longitudinally 10-12 rice in interval is arranged on many transverse drain ditch below the base plate, and described 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; 2-4 rice in interval offers at least four group intercommunicating pores from top to bottom in the upper end of described every rectangular plastic french drain, every group of intercommunicating pore is comprised of 2-3 through hole, and described 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 by the plastics blind pipe respectively.
The drain hole diameter that is opened on the described cushion pool rock side slope is the 30-60 millimeter, hole depth 8-12 rice.
The utility model advantage is that described rectangular plastic french drain has the out-of-flatness, the Assembling that the adapt to excavation slope simply and easily characteristics of constructing, be connected with the rectangular plastic french drain and form the System drainage network being opened in drain hole on the described cushion pool rock side slope, greatly reduce the reverse water pressure power of steel concrete side slope, improved the stability of steel concrete side slope.

Fig. 2 is drain hole described in the utility model and the longitudinal plan that is connected of gutter.
Fig. 3 is drain hole described in the utility model and the drawing in side sectional elevation that is connected of gutter.
Fig. 4 is the plan structure schematic diagram of Fig. 1.
The specific embodiment
Shown in Fig. 1-4, the discharge structure of cushion pool excavation slope described in the utility model, the cushion pool side slope 1 and the base plate 2 that comprise reinforced concrete structure, longitudinally be arranged on five longitudinal drainage ditches 3 below the described base plate 2, longitudinally 12 meters at interval is arranged on many transverse drain ditch 4 below the base plate 2, and described 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; 3 meters at interval offers four groups of intercommunicating pores from top to bottom in the upper end of described every rectangular plastic french drain 5, described every group of intercommunicating pore is comprised 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 ° by round plastic blind pipe 6 respectively, the diameter of described 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 again one deck geotextiles; Cause the movement 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.
