Detailed Description
The embodiments of the present invention will be described in detail below, and the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1-5, the hole sealing and fixing tube for the limestone directional long drilling water stop sleeve comprises a sleeve body 1, wherein a retainer ring 2 is fixedly connected to the sleeve body 1, and a plurality of through holes 21 are formed in the retainer ring 2.
In the work progress, in the casing body 1 installed the drilling, at this moment, retaining ring 2 strutted on the pore wall of drilling, had avoided casing body 1 direct contact drilling's pore wall.
The through holes 21 are internally and uniformly assembled with mud pipes, and during construction, mud is poured into the mud pipes and is discharged from the mud pipes to enter the drill holes.
In order to avoid pouring into mud in-process, jack-up sleeve pipe body 1, the assembly connection has a plurality of to prevent jack-up part 3 on the above-mentioned sleeve pipe body 1, prevent jack-up part 3 and all include the installation hoop 31 of assembly connection on sleeve pipe body 1, a plurality of reinforcing steel piece 32 of fixedly connected with on the installation hoop 31. The reinforced steel sheets 32 are fixedly connected in a welding mode, and the reinforced steel sheets 32 are arc-shaped.
Specifically, when the casing body 1 is installed in a borehole, the reinforcing steel sheets 32 (the reinforcing steel sheets 32 are arc-shaped) can prevent the casing body 1 from jacking up the casing body 1 (the reinforcing steel sheets 32 are welded on the outer side wall of the installation hoop 31) during grouting of the borehole.
In particular, because the reinforcing steel sheet 32 is supported on the hole wall, the reinforcing steel sheet 32 is solidified in the slurry filling process, and the stability of the casing body 1 is further improved.
The mounting band 31 is assembled and connected to the sidewall of the casing body 1 by a plurality of assembling bolts 321.
