Description
Technical field
The utility model relates to agricultural horticulture industry field, particularly a kind of dewatering installation for reclamation.
Background technology
People often can run into the large and higher situation that causes local ponding draining difficulty of groundwater table of soil stickiness in the construction of daily agricultural gardening, the development of such situation continued will cause nursery stock to rot root, death.In the face of this situation, common solution is gutter drainage to be set to solve.But for the demanding place of landscape effect, this solution is difficult to be accepted, and construction is got up also pretty troublesome.
Chinese patent literature publication number CN 101307600A(application number: 2,008 10055390. 7) disclosed " method of consolidating soft soil ground foundation by dynamic pre drainage consolidation " may further comprise the steps: 1) the pre-draining device is made and is installed; 2) first pass pre-draining, and the auxiliary measure that increases dynamic drainage; 3) dynamic consolidation for the first time; 4) second time pre-draining; 5 dynamic consolidations for the second time; 6) the 3rd time pre-draining and dewatering installation are removed; 7) dynamic consolidation for the third time.This invention organically combines well-points dewatering technology, dynamic drainage technology and strong rammer dynamic consolidation technology based on dynamic characteristics, discharging consolidation mechanism and the dynamic consolidation mechanism of saturated soft soil, has guaranteed enforcement and treatment effect on soft foundation.The pre-draining device that adopts is comprised of well-point pipe dewatering installation, arm, total collection pipe, drainage power unit, wherein, the tube core of the well-point pipe of said well-point pipe dewatering installation is the PVC pipe, is divided into three sections from bottom to top, there is end cover the hypomere bottom, is precipitating phase; The permeable hole that cross-distribution is arranged on the stage casing is the drainage section; Epimere is dead pipeline section; The outer vertically binding of the tube core of drainage section has the support pipe support, its outer wrapping nonwoven Inner filter net is gone back longitudinal separation centralizer is set on the drainage section, centralizer is twin nuclei, inner and outer ring distance 3-5cm, have pull bar to connect, inner ring sleeve is put on tube core and Inner filter net, is fixed on the tube core with tapping screw, outer shroud is nested with the nylon outer leaching net outward, filling filtrate between Inner filter net and the outer leaching net, outer leaching net are 60-80 purpose nylon leaching nets, and the transmission coefficient of Inner filter net is less than outer leaching net; After in weak soil, setting wellhole with high pressure jetting water method, the well-point pipe dewatering installation is put into the hole and exposed interface, when the well-point pipe dewatering installation uses take 30-50 as one group, with steel wire tube every well-point pipe is connected on each arm, arm then couples together with total collection pipe, such well-point pipe dewatering installation, arm and total collection pipe form the pipe-line system of catchmenting, total collection pipe is connected with the drainage power system, work by the drainage power unit, underground water sees through outer leaching net and enters filter material layer, filtered by Inner filter net by filter material layer, permeable hole enters the well-point pipe tube core, is sucked to enter arm again, gets rid of outside the venue by total collection pipe again.Though this invention is applicable to the fixing of soft foundation, and inapplicable horticulture industry is to the improvement of reclamation.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, to propose and study a kind of dewatering installation for reclamation.
Technical solution of the present utility model is that employing collecting well, gutter have drain hole on the tube wall of gutter, it is characterized in that, gutter links to each other with collecting well, forms the draining gas venting system, drain hole is uniform on the tube wall of gutter, and the gutter outer wall has the nonwoven clad; Have the gutter of nonwoven clad to be placed in the collecting gutter, collecting gutter and native contact position cover nonwoven.
Its spy is, the diameter 10mm of drain hole, mutual spacing 20mm.
Its spy is, the cross section of collecting gutter is at least 450mm * 450mm.
Its spy is, the macadam that is provided with in the collecting gutter.
Its spy is have the gutter of nonwoven clad to be placed in collecting gutter medium stone layer.
Its spy is, gutter has a plurality of, has the gutter of nonwoven clad to be composed in series a drainage system by a plurality of.
Operating principle of the present utility model is to utilize gutter to collect unnecessary ponding in the soil, dewatering, when high the or moisture content of groundwater table is large, water can see through rubble and flow in the collecting well through gutter, drains by collecting well, makes the water level in the soil remain on certain height.In addition, the gutter that the utility model adopts also has certain permeation functions, can guarantee the respiration of root system.
Innovative point of the present utility model is: 1, utilize the unnecessary ponding in the gutter collection soil, improve soil texture, dewatering.When high the or moisture content of groundwater table was large, water can see through macadam, flow in the collecting well through gutter to flow away, and makes water level remain on certain height.2, gutter also has certain permeation functions, can guarantee the respiration of root system.3, it is simple in structure, easily implements.4, the more place of rainwater that is applicable to of the present utility model.More such as the southern china rainwater, groundwater table is higher, and soil stickiness is large, and impeded drainage, plant percent are not high, adopts the utility model can effectively solve a large tracts of land greening difficult problem, and dewatering improves soil texture, improves plant percent.
The utility model has the advantages that, novel, rational in infrastructure, economic and practical, and install simply, successful, construction cost is lower, not only can improve soil texture suitably precipitation, draining and ventilative, plays the effect of improvement soil.Guarantee the survival rate of nursery stock and good growing way, also do not affect the appreciation effect of environment.
