Specific embodiment

To make the structure feature to the utility model and the effect of being reached has a better understanding and awareness, to compared with Good examples and drawings cooperate detailed description, are described as follows:

Embodiment 1

Anti- well drilling installation steel pipe sleeve construction technique, using pneumatic cucurbit as promoting power, by sleeve from it is vertical now Mouth promotes the mode that side assembles to top, is promoted suitable for reading to vertical eye by all steel bushings and is fixed, finally with concrete pair Hole wall carries out filling reinforcing.Specifically includes the following steps:

(1) sleeve is processed

1, sleeve 1 is processed with 5mm steel plate, diameter 1000mm, and head saves high 1000mm, remaining sleeve 1 is 1500mm high, every section weight 183kg, drilling 10 section sleeves 1 (14.5m) of set, always weighs about 1830kg.

2, the 11# I-steel for suturing two right-angled intersections in first section sleeve 1 with M20 screw, forms cross girder steel 11, is used for Wirerope is fastened when lifting, as shown in figure 3,

3, every section sleeve 1 away from it is upper it is lower along the position 150mm pass through sleeve 1 uniformly weldering 4 M20 bolts 12, stitched in between sleeve 1 Connection is closed, as shown in Figure 1 and Figure 2.

(2) construction method

1, boom hoist cable connects: pneumatic cucurbit 40T anchor chain is hung in the U-shaped capplce of chamber support, by a diameter 18.5mm wirerope upper end card becket bridle hangs over pneumatic cucurbit, and the other end is transferred to vertical mouth now, and wirerope is consolidated using 3 secondary rope cards It is scheduled on the 11# steel I-beam 11 that first section 1 inner cross of sleeve is intersected, restrict card spacing 200mm.

2, steel bushing 1 connects:

(1) start pneumatic cucurbit above to be mentioned first segment sleeve 1, stop when above mentioning to sleeve 1 away from bottom plate heights 1600mm, By standing the operator of mouth now, the second section sleeve 1 is moved on to and has been promoted immediately below sleeve 1, and confirmed and welded on two section sleeves 1 4 12 consistencies from top to bottom of M20 bolt, with 10mm thick steel plate process 13 top nut of connecting plate suture.

(2) because of vertical eye chamber height limit suitable for reading and cucurbit travel limit, every promotion suture one section sleeve, 1 ommatidium top operation Personnel will block rope again, and sleeve 1 lands when card rope again, and repetitive operation later is successively sutured by processing number, until end Save sleeve 1.

3, steel bushing 1 is fixed:

(1) etc. after 10 section sleeves 1 promote suture, it is suitable for reading on head section sleeve 1 along the downward position 200mm bolt Two 2000mm long 10# channel steels on 12, channel steel are carried on a shoulder pole on bottom plate.

(2) after sleeve 1 is fixed, consolidation by grouting is carried out to the gap between sleeve 1 and the vertical eye borehole wall, eye is suitable for reading to be applied by standing Worker person is manually in the milk with slurry.

(3) safety notice

1, when pneumatic cucurbit is fixed on U-shaped canopy with anchor chain, it is necessary to non-skid feature that is solid and reliable, and wanting.

2, eye personnel suitable for reading are stood, when entering progress operation within the scope of 5 meters away from vertical eye mouth, it is necessary to wear safety rope.

3, it stands after eye sleeve 1 installs, it is necessary to covered tightly with plank by jacket wall is suitable for reading, prevent sundries from falling into intraocularly.It stands now Operating personnel, forbidding to stand carries out operation in the lower section of just opposition eye.

4, sleeve 1 is in sewing process, when moving alignment to 12 operation of bolt, is operated with specific purpose tools such as pointed cones, sternly Taboo directly prevents hand from crushing injury with hand.

Embodiment 2

As shown in Figure 1 and Figure 2, anti-well drilling steel pipe sleeve, applied to steel pipe sleeve construction work described in above-described embodiment 1 Skill, steel pipe sleeve 1 include multi-section sleeve 1, and multi-section sleeve 1 is connected by connection structure head and the tail.The connection structure includes sleeve 1 Away from above and below along the welding of certain distance position 4 bolts 12, connecting plate 13；4 bolts 12 are evenly distributed on 1 surrounding of sleeve, and spiral shell Bolt 12 is horizontal through 1 barrel of sleeve；Screw hole there are two being opened up on the connecting plate 13；Spacing and upper and lower two between two screw holes The adjacent two screw rod spacing of a connection sleeve 1 are equal；Connecting plate 13 is by two screw holes also cross upper and lower two sections sleeve 1 Bolt 12, and fixed by nut.

Edge is further fixed on 4 pieces of guide plates 14 on the sleeve 1；The horn-like guide channel that 4 pieces of guide plates 14 surround.Up and down Two sleeves 1 are in alignment, by 4 pieces of guiding of guide plate 14, it can be achieved that quick alignment.

Basic principles, main features, and advantages of the present invention has been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only the principles of the present invention, the utility model also has respectively on the premise of not departing from the spirit and scope of the utility model Kind changes and improvements, these changes and improvements are both fallen in the range of claimed invention.The requires of the utility model Protection scope defined by appended claims and its equivalent.
