Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in figures 1-4, the present embodiment includes multiple bagged sand well casing 10, sand drain pipe installing mechanism 30 and water-pumping/draining
Device 20；The structure of this bagged sand well casing 10 includes the cloth bag 2 that geotextiles is seamed into, and this cloth bag is the sand grains 5 of thick type in loading, should
A diameter of 80mm～100mm of sand grains；The center of this cloth bag is provided with metal tube 1, when this metal tube specification is 3/4；This metal tube
Pipe at the bottom of seal；The side of this metal tube is provided with multiple to perforation 3 along the length direction of pipe, this to perforation 3 along the length side of pipe
To every 200mm left-right situs, and phase adjacency pair perforation 3 is set to be alternately arranged in 90 °；This is 5～8mm to the aperture of perforation；
Optimum aperture is 6mm；This is set to the height of overhead about 2m to the extreme lower position of perforation；As shown in Figure 1；
This metal tube arranges metal grid emery cloth 4 to the periphery of perforation and wraps up, and the size of this metal grid is less than sand grains
Diameter, its objective is to avoid the sand grains 5 in cloth bag to be inhaled in described metal tube and from metal tube discharge；
Described metal tube 1 connecting branch 11, is collected by arm 11 and is connected to house steward 12, suction pump 16 and pump 15 difference of pouring water
It is connected with house steward 12 with irrigation pipe 13 by drinking-water pipe 14.
Sand drain pipe installing mechanism 30 includes casting pile steel mould-pipe 31, shoe 32, vibration hammer 33, tie-beam 34, head tree 35, compression bar
36 and promote bracing frame 37；
This lifting bracing frame 37 bottom connects multiple compression bars 36, and this compression bar 36 pushes up the top of bag pressing sand loading well casing 10,
And be pressed in casting pile steel mould-pipe 31；This compression bar top connects lifting bracing frame 37, and this lifting bracing frame 37 can be along head tree 35
Lower movement；Connect a vibration hammer 33 below this head tree 35, below this vibration hammer 33, connect a connection with multiple casting pile steel mould-pipes 31
Beam 34；As shown in Figure 2,3；
The Φ 200mm casting pile steel mould-pipe 31 at 1 meter of 4 intervals arranged side by side, this casting pile steel mould-pipe on the tie-beam 34 of sand drain pipe installing mechanism 30
Lower end is inserted in and is unloaded formula shoe 32, and tie-beam 34 and vibration hammer 33 are all connected with as entirety, and they are along head tree 35 sliding,
Similar Construction Vibration driven cast-in-place pile.
It is 1～1.5m that the present invention implants the adjacent spaces of bagged sand well casing 10 on contaminated soil；At every 1000m2Dirty
Configure in dye land area-set suction pump is cultivated with foul water tank and clean cistern, referred to as unit with pour water pump and corresponding pipeline
Soilization processing system；By the exploration report of Polluted Soil, bagged sand well casing 10 must pass through Polluted Soil and time Polluted Soil, sand wick
The end of pipe 10, must be touched and be run into clean soil.Metal tube 1 connecting branch 11 at sand drain pipe 10 center, is collected by arm 11 and is connected to house steward
12, suction pump 16 is connected with house steward 12 with irrigation pipe 13 by drinking-water pipe 14 respectively with pump 15 of pouring water；
Exist when soft soil layer soil extrusion in construction driven cast-in-place pile and on casting pile steel mould-pipe, pull out the weak soil resilience shrinkage cavity phenomenon squeezed,
Surveying at soft soil layer, be inserted in detachable concrete shoe with Φ 325mm casting pile steel mould-pipe, soil compaction Construction Vibration sinks to soil layer 12 meters, so
And vibrate and extract Φ 325mm casting pile steel mould-pipe, the concrete shoe in stake holes is risen to-5.2 meters of stoppings by-12 meters, now the stake holes of 12 meters
Becoming the stake holes of 5.2 meters, illustrate that the gravity pressure in casting pile steel mould-pipe is not enough, in casting pile steel mould-pipe, the gravity pressure of blank pipe is zero；Because of sand drain
The deadweight of pipe 10 is the least, it is impossible to embedment is to the elevation required, the present invention uses compression bar 36 mechanism, this compression bar top bag pressing sand loading
The top of well casing 10, the top of compression bar 36 is provided with the lifting bracing frame 37 of sufficient gravity pressure, makes bagged sand well casing 10 exist
Sand drain pipe 10 when dialling casting pile steel mould-pipe 31 will not be produced in length of embedment and follow rising；May be used without sand drain pipe 10 and insert casting pile steel mould-pipe 31
Fill clear water, increase gravity pressure in pipe, but water flooding construction is inefficient.
The program that soil layer imbedded by sand drain pipe 10 is as follows, as shown in Figure 3；
1. in the position pre-buried concrete shoe 32 of embedment sand drain pipe 10, casting pile steel mould-pipe 31 being inserted in concrete shoe 32, correction is vertical；
2. vibrate and the casting pile steel mould-pipe 31 being inserted in band concrete shoe is sunk to soil layer to the elevation required；
3. casting pile steel mould-pipe 31 inserts sand drain pipe 10, uses compression bar 36 to push up the top of the central canal 1 in pressure sand drain pipe, vibration
On pull out casting pile steel mould-pipe 31；
4. casting pile steel mould-pipe 31 all extracts soil layer, now sand drain pipe 10 degree of depth on request embedment soil layer；
Water-pumping/draining device 20 includes the arm 11 that the metal tube 1 with cloth bag is connected, and arm 11 connects house steward 12, this house steward 12
The irrigation pipe 13 of pump 15 of pouring water with band with the drinking-water pipe 14 of band suction pump 16 respectively is connected, and this suction pump 16 connects a foul water tank
18, this pump 15 of pouring water connects a cleaning water tank 19, as shown in Figure 4；
The program of soil sanitation construction is as follows；
Water level height according to Polluted Soil determines the scheme that Polluted Soil dialysis is administered；For high water level area, can will draw water
The water flow of pump 16 is down to during the 20% of normal pumping flow quit work, and the water in the soil particle space in Polluted Soil is described
Major part by pump drainage to foul water tank 18；Sewage pump drainage amount and pollutant load is obtained by detection；Then pump 15 of pouring water is started,
The clean water pouring into the same volume by described sewage pump drainage amount in Polluted Soil pours in this Polluted Soil, this clean water pressure filling
Enter in the space of Polluted Soil granule and stop；Restart suction pump 16 to draw water construction, so repeat pressure and pour water the friendship with press water
For operation, it is achieved the cleaning of soil, until the pollutant load of the contaminant water in foul water tank reaches requirement.
For the nonirrigated farmland that water level is the lowest, start pump 15 of pouring water, continuous water filling 2～3 days so that soil is sufficiently soaked
Bubble, then by above-mentioned alternate irrigation and the alternately operating that draws water, completes the cleaning to soil；Until reaching to allow pollutant load
Requirement, completes soil sanitation and processes.
Described clean water refers to the river without pollutant or river；The construction of drawing water of last suction pump 16 is preferably arrived anhydrous
Can be till pump drainage；What pump 15 of pouring water poured into soil is to plant liquid without earth culture, owing to irrigation and drainage are cleaned repeatedly, removes pollutant in soil
Meanwhile, the fertility in soil the most significantly declines, and needs pressure filling to plant liquid without earth culture so last, in order that increase soil fertility
Measure.
