Detailed description of the invention
For making this utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
As shown in Figure 1, 2, the combination casing that the present embodiment provides includes top 1, middle part 2,3 three, bottom
Unit saves.Each unit joint barrel 4 is rolled by steel plate and forms, and unit joint is connected by attachment means, and each unit saves
It is equipped with outward grouting pipe 8.Described attachment means includes for being fixed on relatively at upper unit joint barrel 4
Upper connector 6 with for be fixed on relative under unit save the lower connector 5 on barrel 4, upper connector
6 are connected fixing with lower connector 5 by bolt 17.It is provided with rubber between upper connector 6 and lower connector 5
Pad 16.Bolt 17 be respectively arranged at two ends with a spring shim 18.
As it is shown on figure 3, the steel plate thickness of the barrel 4 on top 1 is relevant to stack shell diameter.Upper connector 6 is arranged
Lower connector 5 on the position of 15mm on the upper side bottom top 1, with middle part 2 or bottom 3 passes through bolt
17 connect.The chucking lug 7 of U-shaped structure equidistantly distributes around barrel 4, with the distance at both ends is
15mm；Osculum 9 is evenly distributed on the surrounding on top 1, distance top 1 upper end 100mm, osculum 9
Also serving as the hanger of combination casing, osculum 9 is provided around reinforcing plate 10, and crane gear utilizes osculum 9 to incite somebody to action
Combination casing lifting, transfers after carrying out centering and perpendicularity adjustment.The grouting pipe 8 on top 1 is with holes thin
Wall steel pipe, its outsourcing filter screen 11, the chucking lug 7 through stack shell two ends is fixed, grouting pipe 8 upper end
Connect ball valve 12, when casing pulls out difficulty, implement to inject the operation of bentonite slurry, to lubricate barrel week
Enclose the soil body and then minimizing casing pulls out resistance.
As shown in Figure 4, barrel 4 material at middle part 2 and the position of upper connector 6 are identical with top 1, lower company
Fitting 5 exceeds barrel 4 upper end 15mm, is bolted with adjacent cells joint.The length at middle part 2 is respectively
Being processed into 3m, 2m, 1m and 0.5m, the middle part 2 of different size can be combined into different length, it is achieved protects
The flexible of tube length degree.Often joint barrel is equipped with thin-walled grouting pipe 8 with holes, wraps up in filter screen outside grouting pipe 8
11, it is fixed in the chucking lug 7 at barrel two ends.
As it is shown in figure 5, the long 0.5m in bottom 3, including barrel 4, chucking lug 7, grouting pipe 8, upper connection
