Abstract
The utility model relates to an all casing pipe. The all casing pipe comprises a drill bit part, a pipe body and a connector part. A front-end drill bit of the drill bit part is a sawtooth titanium alloy drill bit which comprises inner teeth, middle teeth and outer teeth. A high-pressure grouting pipe is arranged inside the sawtooth titanium alloy drill bit and penetrates through the whole all casing pipe in the axial direction. The outer diameter of the sawtooth titanium alloy drill bit and the outer diameter of the connector part are the same and are both larger than the outer diameter of the pipe body. The all casing pipe has the advantages that the cutting speed is high, work efficiency is high, and losses of equipment are small.
Description
Technical field
The utility model relates to a kind of full-sleeve.
Background technology
During the construction of full-sleeve method, the titanium alloy drill bit one direction sawtooth that tradition is common, when cutting soil or obstruction, often drill-pipe-sticking-head, and drill bit is consistent with pipe shaft external diameter, and it is larger that full-sleeve enters underground darker moment of torsion, and full-sleeve power set moment of torsion is limited, very likely there is card pipe phenomenon.
Utility model content
The purpose of this utility model is to provide a kind of full-sleeve, to overcome currently available technology above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A full-sleeve, comprises bit part, pipe shaft and interface section, and described bit part front end drill bit is sawtooth titanium alloy drill bit, and described sawtooth titanium alloy drill bit comprises internal tooth, middle tooth and external tooth; Described sawtooth titanium alloy drill bit internal is provided with a high-pressure slip-casting pipe, described high-pressure slip-casting pipe axially connects described full-sleeve, described sawtooth titanium alloy drill bit is consistent with the external diameter of described interface section, and described sawtooth titanium alloy drill bit is larger than the external diameter of pipe shaft with the external diameter of described interface section.
Further, on described pipe shaft, establish some perforates.
Further, described high-pressure slip-casting pipe external diameter peripheral hardware high-pressure slip-casting protection of pipe cover.
Further, the diameter of described high-pressure slip-casting pipe is 10mm.
Further, described sawtooth titanium alloy drill bit with the external diameter of described interface section than the large 20mm of the external diameter of pipe shaft.
The beneficial effects of the utility model are: cutting speed is fast, operating efficiency is high, and equipment loss is little.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the full-sleeve elevation described in the utility model embodiment;
Fig. 2 is the full-sleeve lateral view described in the utility model embodiment;
Fig. 3 is the sawtooth titanium alloy drill bit shaft mapping described in the utility model embodiment.
In figure:
1, sawtooth titanium alloy drill bit; 2, pipe shaft; 3, interface section; 4, high-pressure slip-casting pipe; 5, bit part; 11, internal tooth; 12, middle tooth; 13 external tooths; 6, high-pressure slip-casting protection of pipe cover; 7, perforate.
The specific embodiment
As Figure 1-3, a kind of full-sleeve described in the utility model embodiment, comprise full-sleeve bit part 5, full-sleeve pipe shaft 2 and interface section 3, described bit part 5 front end drill bits are sawtooth titanium alloy drill bit 1, a high-pressure slip-casting pipe 4 of described sawtooth titanium alloy drill bit 1 inner outfit, described high-pressure slip-casting pipe 4 axially runs through full-sleeve, described high-pressure slip-casting pipe 4 external diameters are established high-pressure slip-casting protection of pipe cover 6, described sawtooth titanium alloy drill bit 1 is consistent with the external diameter of described interface section 3, and described sawtooth titanium alloy drill bit 1 is larger than the external diameter of pipe shaft 2 with the external diameter of described interface section 3, on described pipe shaft 2, establish some perforates 7.Sawtooth titanium alloy drill bit shaft mapping described in the utility model embodiment as shown in Figure 3, described sawtooth titanium alloy drill bit 1 comprises internal tooth 11, middle tooth 12 and external tooth 13.
The diameter of described high-pressure slip-casting pipe 4 is 10mm.The external diameter of described sawtooth titanium alloy drill bit 1 and described interface section 3 is than the large 20mm of the external diameter of pipe shaft 2.The external diameter of pipe shaft 2 is less than the external diameter of sawtooth titanium alloy drill bit 1, and full-sleeve and surrounding ground contact area are reduced, thereby make full-sleeve view and emulate resistance, reduces.
Described pipe shaft 2 is established some perforates 7, one, utilizes hole seepage flow slurries, thereby reaches the inside and outside Starch Level uniformity of full-sleeve, and lubricated full-sleeve, reduces to reach the frictional resistance that full-sleeve creeps into or extracts; The 2nd, save material, alleviate deadweight, convenient lifting and transportation; The 3rd, good looking appearance, generous, has higher use value, suits large area to popularize.During concrete enforcement, the pitch of holes between described perforate 7 should make full-sleeve energy bearing certain pressure.
Three sawtooth on described sawtooth titanium alloy drill bit 1 are realized respectively different cut direction when cutting, thereby carry out respectively three kinds of functions: soil or obstruction in described internal tooth 11 cutting full-sleeves, make the obstruction in full-sleeve separated with surrounding ground, reduce full-sleeve frictional resistance; Soil or obstruction under described middle tooth 12 cutting full-sleeves, make full-sleeve sink smoothly or to decline; Soil or obstruction outside described external tooth 13 cutting full-sleeve full-sleeves, make full-sleeve separated with soil or obstruction outside full-sleeve, reduces full-sleeve frictional resistance.Through bit work, obstruction, full-sleeve are peeled off from underground soil, be convenient to reduce the moment of torsion of full-sleeve power set, thereby make full-sleeve rotary work lighter.
Simultaneously, sawtooth titanium alloy drill bit 1 disposes high-pressure slip-casting pipe 4, utilizes high-pressure slip-casting pipe 4 that slurries are delivered to sawtooth drill bit position, guarantees the terminal pressure of slurries output, thereby realize following technique effect: the one, utilize high pressure slurries cutting soil, reduce full-sleeve frictional resistance; The 2nd, utilize slurries to carry scum silica frost, avoid the closely knit full-sleeve that blocks of dregs; The 3rd, utilize slurries to carry out retaining wall, avoid full-sleeve to creep into or the process of extracting in, cause that surrounding ground caves in, thereby accelerate the operating efficiency of full-sleeve.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
