Abstract
The present invention relates to tube well construction.A kind of steel pipe downcast pipe well removal method of the present invention, including：Four hangs muscles of welding are evenly arranged in pipe well outer wall when sinking and setting precipitation steel tube well, hangs muscle welds together with downcast well pipe interruption, and one suspension ring of welding are spaced in hangs muscle；Fillter section outer wall when setting steel tube well that sinks is wrapped up using nylon gauze, and remaining lengths of steel pipes outer wall is wrapped up with hangs muscle using plastic sheeting, isolates contact of the well casing with the soil body；After precipitation pipe well is using terminating, the base of frame shape is set in pipe well mouthful, four jack are symmetrical arranged on base, jack jacking position sets undercarriage, and undercarriage sets lifting rope with pipe well top suspension ring corresponding position, and lifting rope is connected with the suspension ring at the top of pipe well；Then start jack, gradually extract pipe well；After the Overstroke of jack, jack is resetted, lifting rope is connected next position suspension ring again, and so on pull out pipe well.The present invention is reduced to potential safety hazard and the pollution to environment.
Description
Technical field
The present invention relates to tube well construction, more particularly to steel pipe downcast tube well construction.
Background technology
The precipitation steel tube well being commonly used at present generally can be all being abandoned in the soil body of underground after dewatering construction terminates, because of steel
Pipe well is embedded in the soil body for a long time, and outer wall corrosion is engaged with the soil body makes steel tube well outer wall increase with the frictional force of the soil body, it is impossible to
Pull out, the depth of part reduced pressure dewatering well can even exceed 60m, these are retained in the steel pipe that underground cannot take out can be over time
Passage progressively corrosion, underground water and soil resources are polluted.
The content of the invention
It is contemplated that overcoming the defect of prior art, there is provided a kind of steel pipe downcast pipe well removal method.It is of the invention simple
It is easy to operate, reduce to potential safety hazard and the pollution to environment.
In order to solve the above-mentioned technical problem, a kind of steel pipe downcast pipe well removal method of the invention, it includes：
Step one, 4 hangs muscles of welding, the same downcast well pipe of hangs muscle are evenly arranged when sinking and setting precipitation steel tube well in pipe well outer wall
Interruption welds together, and a suspension ring are welded every 600 ~ 1000mm in hangs muscle；
Step 2, heavy fillter section outer wall when setting steel tube well wrapped up using nylon gauze play filtering and isolation outer wall of steel pipe with
Soil body contact action, remaining lengths of steel pipes outer wall is wrapped up with hangs muscle using plastic sheeting, isolates contact of the well casing with the soil body, is reduced
Frictional resistance during tube drawing；
Step 3, after precipitation pipe well is using terminating, the base of the good frame shape of pre-production is set in pipe well mouthful, right on base
Claim to set four jack, jack jacking position sets the undercarriage of pre-production, and undercarriage is corresponding with pipe well top suspension ring
Position sets lifting rope, and lifting rope is connected with the suspension ring at the top of pipe well；
Step 4, then starts jack, and pipe well will gradually be pulled out；During tube drawing after the Overstroke of jack, will
Jack resets, and again the next position suspension ring in lifting rope connection well casing hangs muscle, and so on, pipe well is smoothly pulled out.
A kind of described steel pipe downcast pipe well removal method, the step 4 kind is to prevent deeper pipe well hole during extraction
Wall is caved in, and rubble can be inserted in pipe well, and when pipe well is pulled up, the steel wire buckle in shaft bottom can be opened under the gravity of rubble,
Shaft bottom will depart from pipe well.
Present invention process principle is simple, is easy to operation, the potential safety hazard that lifting power inequality is brought when solving crane tube drawing.
Well casing local pressure cannot be pulled out with well casing and tear that to disconnect the safety for producing hidden suddenly when hangs muscle, the use of suspension ring solve tube drawing
Suffer from.Well casing after extraction can be utilized repeatedly, and long-term use can produce considerable economic benefit and social benefit.The present invention can be over the ground
Lower water and soil resources play a protective role, and response country is to engineering construction low stain, non-harmful requirement.
Brief description of the drawings
Below in conjunction with the accompanying drawings, invention is further described：
Fig. 1 is elevational schematic view of the present invention；
Fig. 2 is A-A directions view in Fig. 1.
Specific embodiment
As shown in figure 1, being evenly arranged four hangs muscles 2 of welding in the outer wall of pipe well 1 when sinking and setting precipitation steel tube well, hangs muscle can be same
Downcast well pipe interruption welds together, and a suspension ring 3 are welded every 600 ~ 1000mm in hangs muscle, heavy fillter section when setting steel tube well
Outer wall is wrapped up using nylon gauze and plays filtering and isolation outer wall of steel pipe and soil body contact action, remaining lengths of steel pipes outer wall and hangs muscle
Wrapped up using plastic sheeting, isolate contact of the well casing with the soil body, reduce frictional resistance during tube drawing.Precipitation pipe well is using terminating
Afterwards, the good base 4 of pre-production is set in pipe well mouthful, four jack 5 is symmetrical arranged on base, jack jacking position is set
The undercarriage 6 of pre-production, undercarriage sets lifting rope 7, the suspension ring 8 at the top of lifting rope and pipe well with pipe well top suspension ring corresponding position
Connection, then starts jack, and pipe well will gradually be pulled out.It is to prevent deeper pipe well hole wall collapse during extraction, can be in pipe
Rubble is inserted in well, when pipe well is pulled up, the steel wire buckle in shaft bottom can be opened under the gravity of rubble, and shaft bottom will be with pipe well
Depart from.During tube drawing after the Overstroke of jack, jack is resetted, the next position suspension ring in connection well casing hangs muscle, so
Back and forth, pipe well is smoothly pulled out.
Fig. 2 is shown one embodiment of the present of invention, and in the present embodiment, base is fabricated to square frame according to pipe well size
Shape, and undercarriage is fabricated to matrix pattern, jack is arranged on base corner, and is supported on four angles of undercarriage.
Accordingly, base and undercarriage only need size and pipe well to match, and its shape can be arbitrary shape,
Terrace conditions permit is such as run into, jack directly can be placed on pipe well surrounding ground.
