Below in conjunction with drawings and Examples, the utility model is described in detail.

Consult Fig. 2, first embodiment of the utility model draining sandpipe 2 is arranged at downwards in soil from an earth's surface 99, comprises a top cover 21, being arranged at this earth's surface 99 and is arranged in dewatering installation 23 in this mozzle 22 from this top cover 21 to the mozzle 22 of downward-extension one segment distance and one.

Consult Fig. 3, this top cover 21 comprises a lid 211 and with a discharge orifice 299 and to be arranged in this lid 211 and the grid member 212 with multiple port 288.In the present embodiment, this top cover 21 uses the material than soil more high strength, to provide larger bearing capacity.If but the utility model is arranged on earth's surface 99 (see Fig. 2) live load or the not high region of frequency, also the water-permeable brick of high porosity can be used as the material of this top cover 21, in this lid 21, this grid member 212 also can not be set, this top cover 21 be even set and also can.But as directly offered this discharge orifice 299 on this top cover 21 as the utility model and described port 288 makes surface flow water flow freely into, can be a kind of effectively and take into account the embodiment of tolerance.

Specifically in the present embodiment, this lid 211 also can use concrete material to make, except because concrete Heavy Weight, can increase outside stability of the present utility model, add that its cost is low, also not easily have the risk going adrift and steal and sell.Certainly, this lid 211 also directly can be designed to the aspect of this grid member 212, is not limited in mode disclosed in graphic.

Consult Fig. 2, this mozzle 22 is in hollow form and from this top cover 21 to downward-extension, this dewatering installation 23 is fed through this mozzle 22 from earth's surface 99 and arranges downwards, and be connected with this discharge orifice 299 and described port 288.This dewatering installation 23 comprise one by high porosity filler form in the permeable unit 231 of column and this permeable unit 231 coated and the clad 232 of porous.The length of this clad 232 and this permeable unit 231 exceedes the length of this mozzle 22, make this dewatering installation 23 divide into one by this mozzle 22 around guiding region 233 and not by this mozzle 22 around and away from the catchment 234 on earth's surface 99.

In the present embodiment, this clad 232 be there is water permeability coating film as explanation, the high porosity filler of this this permeable unit 231 of clad 232 Absorbable organic halogens, to maintain the integrality of this draining sandpipe 2.Such as using adhesive-bonded fabric material (Non-Woven Fabric) as the material of this clad 232, both good penetrating power can be provided, high porosity filler can be stayed in this clad 232 again simultaneously, and prevent extraneous soil from entering in this dewatering installation 23 and blocking drain function.In addition, when using adhesive-bonded fabric material, because adhesive-bonded fabric material is buried in soil, can not be subject to the destruction of UV sunlight, again not by earth's surface vehicles or pedestrians spreading, can reach 10 years application life to many decades, setup cost and maintenance cost are all quite cheap.

In addition, this mozzle 22 makes with fluid-tight material, it similarly is such as the material making of PVC plastic sebific duct, not only with low cost and arrange easily, also can not pollute environment, certain reality also can use the material manufactures such as steel pipe, vitrified-clay pipe, concrete pipe when using, depending on considering of setup cost and design function.And the setting position of this mozzle 22 is because close to earth's surface 99, also can firm this dewatering installation 23, avoid the mankind's activity on earth's surface 99 cause the improper movement of this permeable unit 231 or loss and affect function of the present utility model.In addition, this mozzle 22 can also prevent the root of neighbouring plant from invading and destroy this permeable unit 231 and this clad 232, can effectively extend application life of the present utility model.

This permeable unit 231 makes mixed by low amounts cement and sand, and this permeable unit 231 can use in the factory in advance and mixed by low amounts cement, sand and water mix, and make in a mold, as the preparation method of cement mortar, the cement factor just used in the present embodiment is much lower.After the mixture of this low amounts cement, Sha Jishui hardens gradually, the water of mix can leave mixture gradually because of the combination or volatilization with cement and leave many holes, and makes this mixture form mushy cylindrical body.Certainly, this permeable unit 231 also can select different materials to make, such as, only make with sand, or other material with high porosity is made.Use husky as material mainly because husky is natural soil, have environmental protection, nontoxic, harmless, sieve series can be obtained by occurring in nature easily, not only cost is quite cheap, can take into account again environmental protection and the continuous advantage used forever.Especially through the sand of specific dimensions screening, higher porosity can be had, the velocity of liquid assets of water in this dewatering installation 23 can be increased.This permeable unit 231 also can use the material of thicker size such as such as cobble or rubble etc., but when this dewatering installation 23 is implanted in soil layer, if packing material is oversize or have corner angle too many, then easily cause this dewatering installation 23 to implant not easily or cut to have this clad 232 of water permeability, therefore the major consideration of Material selec-tion is still using the naturality of material, easily obtaining, can not cause the factors such as the pollution that surrounding environment is possible.

Consult Fig. 2 and Fig. 4, actual when arranging, as long as first from earth's surface 99 with construction equipment as self-propelled auger machine ... Deng, downward brill excavate have certain degree of depth brill pick hole (such as 3 meters (meter), 6 meters dark or longer brill pick hole) after, this clad 232 is arranged downwards from boring in pick hole, and this permeable unit 231 is filled in this clad 232.Now, this clad 232 can be propped up with the volume of self by this permeable unit 231, then this top cover 21 and this mozzle 22 is inserted in the lump in this brill pick hole again, forms this guiding region 233.Now, be arranged to this guiding region 233 bulging bore pick hole in, and this catchment 234 also can fully and soil fit, so namely complete preliminary assembling of the present utility model.Certainly, during practice of construction, order of its construction can on demand and environment and changing to some extent.

Specifically be, when the high porosity filler selected by this permeable unit 231 is not concretion state, but during respective independently graininess aggregate, such as most of maximum particle diameter is 0.075 millimeter (mm) to the sand (Sand) between 4 millimeters, carry in consideration transport, building site and insert in the demand of sub-surface, first can process in the factory, after making described high porosity filler sclerosis consolidation, transport the installing from building site with the form of bar shaped and also can.During actual use, this permeable unit 231 in bar shaped is not limited to cylindrical shape, also can do rectangularity cylinder or other shape cylinders.Another benefit preposition prior to factory is: this permeable unit 231 in bar shaped is convenient to transport, carrying and constructs insert, and the high porosity of original material can be maintained, even if when implanting because of sub-surface in soil extruding and cause distortion or a small amount of interruption cracked time, non-homogeneous due to the soil in sub-surface, therefore still can leave many less seepage channels, therefore only can reduce drainage efficiency of the present utility model a little, but be unlikely to entirely ineffective.

In addition, if the soil texture near this area set by the first embodiment loosely time, also can fill out with resilient fluid sealant thing in the gap between this top cover 21 and this mozzle 22, similarly be pitch etc., with the infiltration between the gap reducing this top cover 21 and this mozzle 22, extend effective service life of the present utility model.
