Description
Technical field
The utility model relates to a kind of drilling equipment more particularly to a kind of eccentric two-tube guide digging implanters of forward type
Tool.
Background technique
Currently, underground water pollution phenomenon in China's is prominent, and the state developed from point pollution to band-like and facial contamination has been presented
Gesture.In-situ remediation method is not needed with pumping and floor treatment, without excavating, can reduce pollutant exposure, construction infection is smaller,
It is at low cost, repair thoroughly, the advantages that processing pollutant kind is more be continuously improved in the application percentage of European and American developed countries, according to repairing
It answers a pager's call and manages difference, peripheral doses (aeration process, electric repairing technique etc.), chemical remediation, biology in situ reparation and infiltration can be divided into
Transflection answers wall technology etc..
Because of complex formation, pollution level difference is big, underground water pollution reparation difficulty is big, and repair function material was to pollution at that time
There is optimal repairing effect when reaching accurate dispensing.Therefore, whether repair function material can precisely be injected under destination
It is the whether successful premise of in-situ immobilization in water layer, precisely drilling and intelligence injection are the two big key technologies that injection is repaired.
Domestic method for implanting at present has: (1) drilling injection is such as injected using GeoProbe drilling machine, and equipment scale is small, machine
It is dynamic flexible, but pressure is low, and injection efficiency is low, and is primarily adapted for use in solution-type repair materials, granular easy blocking injected hole；
(2) well injection mode can be used normal pressure injection or pressurization injection, relatively be suitable for the layer of sand or unconsolidated formation of liquid material, by
Field conditions are larger, need to understand place geological condition thorough；(3) injection injection, Chang Peihe single pipe method and double tube method
Construct, have spray penetration limitation it is small, can multi-angle injection the characteristics of.
Horizontal directional drill can be laid with various pipelines in most of stratum, but easily collapse when encountering sandy gravel, Extra-fine sand etc.
When stratum, conventional single tube drilling technology can not normal guide digging.Being mainly characterized by for such stratum be loosely organized, degree of cementation
Difference, self-stable ability are poor, monolithic rock strength is high, therefore carry out horizontal directional drill construction in sand-pebble layer and have following problem:
First, borehole wall stability problem, after loose sand-pebble layer is drilled to be opened, the hole wall pole in the case where mud washes away the disturbance with drilling tool
Easily collapse；Second, it is oriented to problem, when being crept into soft or hard staggered sand-pebble layer with horizontal directional drilling technology, when
The direction to drill when encountering biggish erratic boulder is difficult to control；Third, detritus problem, different from being crept into rock stratum, in sandy gravel
When creeping into stratum, cobble particle can't be crushed by drill bit but can rotate together with drill bit, this causes ground to be transmitted
Energy not can be effectively used to fractured rock.
