Construction period；Thus, research and development one kind is simple in construction, uses rational underground leting speeper borehole casing sector hole wall grouting and reinforcing device
The problem of having turned into relevant industries urgent need to resolve.
Tossa superficial white, it is glossy, there is the characteristics of moisture pick-up properties is good, and aproll is fast.
Utility model content
The purpose of this utility model be to provide it is a kind of it is simple in construction, save the slurry wasted in sleeve pipe, avoid hole
Occur situations such as space is not filled by wall, and save drilling and continue to drill through during construction in sleeve pipe needed for the cement mortar of solidification
The underground leting speeper borehole casing sector hole wall grouting and reinforcing device of time.
To achieve the above object, the technical solution adopted in the utility model is as follows：A kind of underground leting speeper borehole casing section
Hole wall grouting and reinforcing device, is included in the drilling of underground leting speeper and inserts sleeve pipe, and the sleeve pipe one end connects with the top plate to drill
Touching, the other end is stretched out outside well, one slip casting tubule of gap location insertion between described sleeve pipe and the borehole wall, the slip casting tubule external connection grouting pump,
Sealing layer is filled with the drilling orifice, described sleeve pipe annular setting at least three on one end of the top plate of drilling is equidistant
The anti-slurry hole of distribution.
As with improvement, located at distance sleeve top at least at 10mm, each two is counter to starch the anti-slurry orifice ring shape
Relative to the angle of casing axis in 120 ° between hole.
As further with improvement, the anti-slurry hole aperture is not more than 10mm.

Beneficial effect：A kind of underground leting speeper borehole casing sector hole wall grouting and reinforcing device disclosed in the utility model, warp
Cross repetition test use and show compared with prior art, there is advantages below：
(1) slurry wasted in sleeve pipe can be saved by using the present apparatus, is avoided in hole wall and space is occurred and be not filled by
Situations such as, and save drilling and continue to drill through the time in sleeve pipe needed for the cement mortar of solidification during construction, it can effectively shorten
Construction period.
(2) it can ensure that cement mortar is full of whole sleeve pipe when aperture back is starched away from cannula tip 10mm instead on slurry hole, ensure note
Starch intensity.
(3) anti-slurry bore dia is not more than 10mm, can effectively ensure that cement mortar normally can drop down, while can prevent because of aperture mistake
Casing strength is caused to reduce greatly.
(4) sleeve is placed in drilling middle part, can prevent in sleeve pipe installation process, and rock dust counter will starch hole plug on the wall of a borehole,
Slurries can not drop down.
