Embodiment
Scheme in the present invention to clearly illustrate, is given below preferred embodiment and is described with reference to the accompanying drawings.
As shown in Figures 1 to 3, the present invention is that one kind utilizes concrete pair using the construction method of anti-well rig maintenance drop shaft
Former pass 1 is backfilled, and is then recycled anti-4 drilling well of well drilling machine to form new pass 9 and carry out set to new drop shaft and is built
The drop shaft comprehensive processing method of the borehole wall, it is comprised the following steps that：
(1) due to after former drop shaft fall damage its structural form can vary widely, thus before being administered to it
The space structure shape of former drop shaft need to be understood, i.e., former 1 space structure of pass is detected, concretely comprised the following steps：
(a) lift 3 is installed on the top of former drop shaft, hanging ultrasonic meter 2 using lift 3 is allowed to slip along original
Well shaft 1 carries out profile scanning one by one to former pass 1 from top to bottom, to obtain the space structure in relation to former pass 1
The data of shape, as shown in Figure 1；
(b) data obtained in step (a) are analyzed, calculates former drop shaft spatial volume, and draw out former drop shaft
The space structure shape of pit shaft 1.
(2) cave in and produce cavity since large area has occurred in the former drop shaft borehole wall, it is whole in order to be carried out to the former drop shaft borehole wall
Body reparation, backfills former pass 1 using concrete in of the invention, to obtain the relatively stable drop shaft borehole wall,
Therefore former pass 1 is filled according to the result of detection of gained in step (1), it is concretely comprised the following steps；
(a1) in view of the present invention is crept into using anti-well drilling machine 4, in order to easy for construction, backfilled to former pass 1
Before, first anti-well drilling machine 4 is installed in place, as shown in Fig. 2, installing drilling machine girder steel 5, Ran Hou in the upper end well head of former drop shaft
Anti- well drilling machine 4 is installed on drilling machine girder steel 5, and anti-well borer drill rod 6 is transferred to the lower end well head of former drop shaft, but due to concrete
In additive may produce corrosion to anti-well borer drill rod 6, and anti-well borer drill rod 6 can be influenced after concrete setting
Rotate, therefore wrapped up anti-well borer drill rod 6 with casing 7, and filled slightly between anti-6 outer wall of well borer drill rod and 7 inner wall of casing
Sand material material, its middle sleeve 7 are plastic tube, select PVC plastic pipe to be used as casing 7 in the present embodiment, using set in this step
Pipe 7 protects anti-well borer drill rod 6, its first purpose is to prevent the additive in concrete to anti-well borer drill rod 6
Corrosion and the rotation easy to the anti-well borer drill rod 6 of raising boring process in subsequent step, another object is that being carried for raising boring
For guide hole, consequently facilitating that entirely constructs is smoothed out；
(b1) after installing anti-well drilling machine 4 and properly protecting to anti-well borer drill rod 6, you can to former pass 1 into
Row filling, as shown in figure 3, its specific steps includes：
(i) concrete to avoid being filled in former pass 1 leaks to influences subsequent construction elsewhere, it will usually
The lower end port of the annular space between 7 outer wall of casing and the former drop shaft borehole wall is blocked using plug members, and in order to anti-
Only concrete bonds together with plug members and is not easy to the dismounting of plug members, and former pass 1 is being carried out with concrete
Before backfill, it will usually be filled with fine sand into former pass 1, the height that is filled with of its medium-fine sand can be according to close to former drop shaft lower end
The destruction situation of the former pass 1 of well head determines, when the former pass 1 close to former drop shaft lower end well head is without destroyed
When, fine sand is filled to the position for the well section lower end well head 1m that is damaged apart from former drop shaft, and fine sand filling length is greater than or equal to 5m；
(ii) grey tremie pipe being slipped using winch handling in brattice way, the wherein internal diameter of tremie pipe is greater than or equal to 150mm,
Then according to the former drop shaft spatial volume precast concrete calculated in step (b), then former pass 1 is carried out paragraph by paragraph
Concrete filling, until the position of 11 upper surface distance borehole drilling rig girder steel of concrete filling body, 5 lower part 0.5m, then refills anti-well
Drilling machine basis concrete, and anti-well drilling machine basis is closely connected with concrete filling body with drilling machine girder steel 5, reach and undertake expansion
The ability of hole load.The concrete foundation that anti-well drilling machine basis concrete filling body is formed forms anti-well with drilling machine girder steel 5 and bores
Machine basis, wherein, drilling machine girder steel 5 is seated in concrete foundation.Concrete foundation is higher than filling concrete strength.This example
In, to concrete used in former pass 1 progress concrete filling marked as C10-20。
(3) raising boring is carried out to the former pass 1 after step (2) filling using anti-well drilling machine 4 and forms new drop shaft
Pit shaft 9：In order to make the concrete of backfill to the former drop shaft borehole wall formed support, using anti-well drilling machine 4 creep into new pass 9 it
It is preceding need and etc. the concrete setting that is filled in former pass 1 in (ii) and intensity reach design requirement, then remove again
Plug members, release the fine sand of filling in former pass 1, then install reaming bit in the lower end of anti-4 drilling rod 6 of well drilling machine
8, reaming from bottom to top, until former drop shaft upper end well head, the new drilling of pass 9 is completed, as shown in Figure 4.Due to each drop shaft
Well depth, the concrete condition such as hole diameter it is different, therefore the set strength for being filled in different pass inner concretes will be according to each
Pass concrete condition determines, usually selects the concrete of low grade to fill pass.
(4) supporting is carried out to the new drop shaft borehole wall drilled in step (3), as shown in figure 5, it is comprised the following steps that：
(I) the anti-well drilling machine 4 in dismantling step (3), installs lift 3 and hanging scaffold 10 on new 9 top of pass, applies
Worker person is using the safe condition that new pass 9 is checked in lift 3 and the new pass 9 of 10 tripping in of hanging scaffold, to part
Unstable formation and concrete are handled and supporting；
(II) progressively pour new drop shaft inner wall from bottom to top by the way of hydraulic pressure synovial membrane, form new ore pass choking-up.
After new ore pass choking-up is formed, you can remove relevant construction equipment, recover charging and ore drawing needed for drop shaft
Equipment, drop shaft is come into operation.
Occur using the present invention to the borehole wall large area cave in and occur cavity former drop shaft carry out maintenance during, to original
Enter pit shaft without personnel when pass 1 carries out the detection of space structure shape, and working as needs construction personnel to enter pass
When, the concrete of backfill has formd the former drop shaft borehole wall reinforcing and filling, is not in caving in for large area, so as to ensure that
The personal safety of construction personnel's quilt, and solve in existing drop shaft restorative procedure in the area that caves in, highly larger place
The problem of construction personnel's operating difficulties.
Above-described embodiment is only intended to clearly illustrate the invention example, and not has to the invention
The restriction of body embodiment.For those of ordinary skill in the field, can also make on the basis of the above description
Other various forms of changes or variation.There is no necessity and possibility to exhaust all the enbodiments.It is all the present invention
Guarantor of any obvious changes or variations extended out within spirit and principle still in the invention claim
Protect among scope.
