Description
Technical field
The present invention relates to a kind of shallow-layer radial drilling technology, especially a kind of many radials drilling well networking method of supplying water.
Background technology
In the prior art, in shallow irrigation water resources development, radial has the features such as water yield of well is large, the life-span long, regulation and control shallow underground outlet capacity is strong, dewatering speed is fast, has good development prospect.Radial comprises the radiating aperture of collecting well and multiple level, and radiant tube refers to throws filter pipe into increase well yield in shaft bottom or the borehole wall by radiation direction, and collecting well is the construction plant of horizontal radiation pipe, is also to collect water source, installs the place of pumping equipment.
For in the radiant tube construction of sand-pebble layer, method conventional at present both at home and abroad adopts hydraulic jack to head into method, adopts hydraulic jack in conjunction with water under high pressure by direct for filter pipe jacking aquifer, or first sleeve pipe is headed into aquifer, sleeve pipe put into by filter pipe again, then extracts sleeve pipe.This method is simple to operate, but jacking length is less, and when particularly external water pressure is less, to head into the resistance that is subject to larger for radiant tube, and jacking length limited system, is no more than 10m usually.According to percussion revolution drilling method, radiant tube construction length can be increased.Radial space less (diameter about 3m), minitype motivation head ballistic work is little, and efficiency is low, and large-sized power area of bed is large, cannot be arranged on radiation pipe construction equipment.And the construction in current radiation hole is workman at underground construction, bad environments, inefficiency, poor stability.
If traditional sand-pebble layer radial is constructed, the major diameter collecting well that relates to adopts and revolves the modes such as excavation formula, dematron and creep into, and drilling cost is high, and pumping irrigation well construction is difficult to bear; If use traditional manually digging a well, or punching is grabbed and is crept into, and adopts to take out cylinder and fish for and bore quarrel, and deslagging method falls behind, and the performance parameter of rig itself limits stroke (i.e. drill bit height of drop) and puies forward Beijing South Maxpower Technology Co. Ltd's power in addition, so that its drilling efficiency is lower.
The present invention proposes a kind of vertical shaft and revolve the technical method scraping out well and guide digging construction radiating aperture, this technical elements yet there are no research and report at present.Probing aspect, the ground such as oil, geology and no-dig technique have some guide digging methods, but due to but due to hole structure, construction cost, docking calculation and space constraint, this method is inapplicable in well drilling well.Therefore, researching and developing a kind of without well construction under workman, the radial construction technology that improves working conditions, increase work efficiency, is the current technical issues that need to address.
Summary of the invention
For above-mentioned shortcoming and defect of the prior art, the object of the present invention is to provide constructing at sand-pebble layer shallow-layer radial of the fields such as a kind of existing agricultural, irrigation, without the need to the drilling technology of workman's underground work with regard to energy Cheng Jing.
The object of the invention is to be achieved through the following technical solutions:
A kind of many radials drilling well networking method of supplying water, in turn includes the following steps:
S1, gets out many crisscross radiating apertures by radiating aperture guide digging technique;

Preferably, described radiating aperture guide digging technique in turn includes the following steps:
S1, directional drill accesses drilling rod and detection drill bit;
S2, utilizes directional drill to pressurize and creeps into, and bassets until detection drill bit reaches target;
S3, unloads detection drill bit, and connect screen casing on drilling rod;
S4, utilizes directional drill to return and drags screen casing, until screen casing exposes former place of burying;
S5, cuts off screen casing on the ground;
S6, fills in cylindrical plug at screen casing fracture, then pumps into cement sealing.
Preferably, described vertical shaft churning drive in turn includes the following steps:
S1, vertically places directional drill mast, connects the downward rotary dig drilling of churning driven head, carries bucket and pours out revolving in bucket and dig thing on bucket is completely rear;
S2, revolves after having dug, and utilizes the vertical shaft of mast by merogenesis of rotary drilling rig, and cement tube well cementation is put in gradation lifting;
S3, silo bottom and the peripheral annular space of cement tube drop into sandy gravel.
Preferably, in the step S4 of radiating aperture guide digging technique, the screen casing be connected on drilling rod is the plastics screen casing that band is porose or stitch.
Preferably, return at the step S5 of radiating aperture guide digging technique and be pulled through in journey, dismantle the drilling rod being back to ground successively.
Preferably, in the step S2 of vertical shaft churning drive, cement tube uses bamboo cane or corrosion resistant plastics as skeleton, prevents electromagnetic shielding.
Compared with prior art, the embodiment of the present invention at least has the following advantages:
Many radials drilling well networking method of supplying water in the embodiment of the present invention, by first construction level radiating aperture, and then radiating aperture infall construction shaft collecting well, solve guide digging precision problem, and do not affect by the down-hole height in horizontal radiation hole; Radial is networked by horizontal radiation well, and water source, down-hole can be helped mutually, can utilize shallow seated groundwater resource to greatest extent.
