Abstract
A water drain pipe type blind drain is characterized in that a water drain pipe is arranged in an inverted filter layer of the water drain type blind drain, a plurality of water drain holes are formed on the pipe wall of the water drain pipe, and the bore diameter of each water drain hole is a half to one fourth of the diameter of a filter material. By the adoption of the structure, the water drain pipe type blind drain can effectively solve the problem in the prior art that the blind drain is easy to block; the blocked blind drain can be dredged conveniently by utilizing an air compressor to prevent the blockade caused by the inverted filter layer formed by crushed stones, so that the water drainage is smoother; the construction and use are simple, convenient and rapid; and the porosity of the surface of the inverted filter layer formed by the crushed stones is increased, the water collection performance is good, and the voidage is enlarged, so that the water drain pipe type blind drain has popularization and application values.
Description
Technical field
The utility model relates to a kind of french drain system that is used for the finished product fines stockyard dehydration of sandstone system, particularly a kind of draining tubular type french drain.
Background technology
Existing sandstone system all adopts in finished product fines stockyard the nature dehydration, promptly some gutters are set in finished product fines stockyard, lay rubble loaded filter french drain formula drainage pattern in adopting,, promptly drop to 3% with 3 days dewatering time moisture content to satisfy finished product fines code requirement; The advantage that has it simply to be suitable for, the problem that exists is, after rubble loaded filter french drain formula drainage pattern uses a period of time, rubble loaded filter void content diminishes, the drainage variation, amount of seepage reduces, and need clear up rubble loaded filter french drain, again lay the rubble loaded filter, to guarantee 3 days dewatering times; Perhaps reinvestment increases fines dehydration position in storehouse, and this has increased construction cost.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of draining tubular type french drain, can solve that french drain easily stops up in the prior art, or the problem that is difficult to clear up after stopping up, and easy construction is quick, and catchmenting property is good.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of draining tubular type french drain, in the loaded filter of weeper drain, be provided with gutter, and described gutter tube wall is provided with a plurality of drain holes.
The aperture of described drain hole be in the loaded filter filter material footpath 1/2 ~ 1/4.
Described gutter two ends are provided with adpting flange, and the adpting flange of an end is connected with sealing flange, and the adpting flange of the other end is positioned on the gutter.
Described gutter two ends are provided with adpting flange, and the adpting flange of an end is connected with sealing flange, and the adpting flange of the other end is connected with air compressor machine by the tube connector of flanged dish.
Described gutter is lower near an end in gutter.
Described drain hole is staggered on tube wall.
A kind of draining tubular type french drain that the utility model provides, by adopting above-mentioned structure, can effectively solve the susceptible to plugging problem of french drain in the prior art, and can utilize air compressor machine to dredge easily after stopping up, prevent that the loaded filter that rubble is formed from stopping up, make draining more unobstructed, construction and easy to use quick makes rubble loaded filter surface percent opening height, and catchmenting property is good, void content is big, has promotion and application and is worth.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the structural representation of gutter in the utility model.
The specific embodiment
In Fig. 1, Fig. 2, the solid accumulation of sealing-tape machine 9 is in finished product fines stockyard, many draining tubular type french drains are set in the stockyard, in the loaded filter 7 of weeper drain 11, be provided with gutter 1, gutter 1 is set to certain draining longitudinal grade and enters in the weeper drain 11, be that gutter 1 is lower near an end in gutter 6, and higher near an end of gallery 10.
Described gutter 1 tube wall is provided with a plurality of drain holes 8.In Fig. 3, described drain hole 8 is staggered on tube wall, thereby the intensity of guaranteeing gutter 1 is reliable.
The adpting flange 2 that described gutter 1 two ends are provided with adpting flange 2, one ends is connected with sealing flange 4, and the adpting flange 2 of the other end is positioned on the gutter 6.
The size in the aperture of described drain hole 8 should be selected for use according to the rubble filter material selected for use footpath size, for example selects 1/2 ~ 1/4 of filter material footpath in the loaded filter 7 for use.Usually selecting the aperture for use is that rubble filter material footpath 1/3 effect is better.Pipe thickness is selected for use more than the tubing thickness 3mm commonly used; Plastics formula flange selection standard spare 0.6MPa.
In Fig. 1, when needs dredging drainpipe 1, the adpting flange 2 of gutter 1 one ends and sealing flange 4 are connected by bolt, the adpting flange 2 of the other end is connected with air compressor machine 5 by the tube connector 3 of flanged dish.Start air compressor machine 5, adjust the air inflow of air compressor machine 5, until the pressure requirement of satisfying mediation.
