Abstract
The invention discloses a horizontal radiation hole guiding drilling process. The process comprises the following steps that 1, a drill rod and a probing drill bit are connected to a guiding drilling machine; 2, the guiding drilling machine is used for conducting pressurization drilling until the probing drill bit enters a vertical shaft; 3, the probing drill bit penetrates through the vertical shaft and continues to conduct drilling until the probing drill bit arrives at the target and is exposed out of the ground surface; 4, the probing drill bit is dismantled, and a screen pipe is connected to the drill rod; 5, the guiding drilling machine is used for pulling the screen pipe back until the screen pipe is exposed out of an original position where the screen pipe enters the ground; 6, the screen pipe is sheared off on the ground, cylindrical plugs are inserted into the screen pipe, and certain cement is pumped to openings of the screen pipe to seal the openings. The horizontal radiation hole guiding drilling process is used for construction of radiation holes of an agricultural well, and two radiation holes can be formed at a time; the radiation holes are formed through one-time pull-back of the flexible plastic pipe, time and labor are saved, workers do not need to go down to the well, and safety is high.
Description
Technical field
The present invention relates to a kind of drilling method, particularly relate to a kind of horizontal radiation hole guide digging technique of water well drilling.
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, again filter pipe is put into sleeve pipe, then extract 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.
The present invention proposes a kind of technical method of radiating aperture of constructing from ground to guide digging vertical shaft, 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, research and develop a kind of without well construction under workman, the ground guiding radiating aperture construction technology that improves working conditions, increase work efficiency, be 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 a kind of when existing major diameter Well Spring Modification, sand-pebble layer well radiating aperture construction, without the need to the guide digging technique 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 horizontal radiation hole 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, until detection drill bit enters vertical shaft;
S3, detection drill bit continues to creep into through vertical shaft, bassets until detection drill bit reaches target;
S4, unloads detection drill bit, and connect screen casing on drilling rod;
S5, utilizes directional drill to return and drags screen casing, until screen casing exposes former place of burying;
S6, cuts off screen casing on the ground
S7, lower cylindrical plug, then pumps into the sealing of certain cement.
Preferably, before directional drill creeps into, in completed vertical shaft, put into detection instrument.
Preferably, described detection drill bit is by creeping under the guide of detection instrument.
Preferably, in step s 2, detection is after drill bit enters into vertical shaft, got by detection instrument and is placed on and detects drill bit and bury and locate the vertical shaft another side position of symmetry.
Preferably, in step s 4 which, the screen casing be connected on drilling rod is the plastics screen casing that band is porose or stitch.
Preferably, return in step S5 and be pulled through in journey, dismantle the drilling rod being back to ground successively.
Compared with prior art, the embodiment of the present invention at least has the following advantages:
In the embodiment of the present invention, horizontal radiation hole guide digging technique is used for the construction of the radiating aperture of agricultural well, and once forms 2 radiating apertures; The completing of radiating aperture adopts flexible plastic pipe once to return to drag shaping, time saving and energy saving, and artificial without the need to going into the well, and safety is high.
Accompanying drawing explanation
Fig. 1 be horizontal radiation hole of the present invention guide digging technique creep into schematic diagram;
Fig. 2 is the structural representation of the screen casing of horizontal radiation hole of the present invention guide digging technique;
Fig. 3 is the partial enlarged drawing of Fig. 1.
Detailed description of the invention
Below in conjunction with Fig. 1-Fig. 3 and embodiment, the invention will be further described, and following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
Horizontal radiation hole guide digging processing step: (1) puts into detection instrument 5 in completed vertical shaft 3; (2) on directional drill 1, access drilling rod 2 and detection drill bit 6; (3) under the guide of detection instrument 5, utilize directional drill 1 to pressurize and creep into, until in detection drill bit 6 vertical shaft 3; (4) detection instrument 5 is got be placed on ground drill target and break ground place's B point; (5) continue to creep into until detect drill bit 6 and reach target and basset; (6) unload detection drill bit 6, and connect the screen casing 7 that band is porose or stitch; (7) utilize directional drill to drag screen casing 71 time, until screen casing exposes a former A place of burying, return and be pulled through continuous dismounting drilling rod 2 in journey; (8) cut off screen casing 7 on the ground, then the both ends open of screen casing 7 is filled in cylindrical plug post-grouting or cement seal.Then a pair radiating aperture 4 is constructed complete, continues lower a pair radiating aperture construction.
