Description
Technical field
The invention belongs to a kind of borehole wall construction methods, and in particular to a kind of freezing pipe of outer case sleeve wears slopes wall construction
Method.
Background technique
Occur water burst sand leakage phenomenon in mine inclines, when administering using freezing process, need to beat freezing pipe into the borehole wall,
Due to water burst sand leakage in pit shaft, water content is more, and when the later period applies construction freezing method, the intensity that water congeals into ice, which is less than, to be contained
Water sand soil forms the intensity of frozen soil after freezing, be unsatisfactory for the demand for security of construction, therefore needs the cementing into pit shaft by casing
Slurries reduce the content of water in pit shaft, it is ensured that freeze rear intensity and meet the requirements, therefore the freezing pipe of outer case sleeve is used to wear inclined shaft well
Wall construction method carries out freezing to repair.
Summary of the invention
The purpose of the present invention is to provide a kind of freezing pipes of outer case sleeve to wear slopes wall construction method, can utilize casing
Freezing pipe is protected, it is ensured that freeze the normal steady progress of work.
The technical scheme adopted by the invention is that:
A kind of freezing pipe of outer case sleeve wears slopes wall construction method, comprising the following steps:
(1) with the drill bit of outer case sleeve from ground tunneled downwards to slopes wall top wall surface, by casing to casing with
Casing and borehole wall upper surface are secured together by cementing slurries A in the borehole wall contact position when cement grout A solidification.
(2) more bit change continues to tunnel, and penetrates borehole wall upper wall, by casing into pit shaft cementing slurries B.
(3) continue driving to borehole wall wall surfaces, after penetrating the lower borehole wall, casing is fixed to borehole wall lower wall bottom end.
(4) after the completion of the conduit crossing borehole wall, freezing pipe is placed in casing, and cement is injected between casing and freezing pipe
Slurries C.
The features of the present invention also characterized in that
Cement grout A is used with setting time is short, bond strength is high, waterproof performance is good, leakproofness in the step (1)
Strong slurries.
Using having the cement grout for not changing freezing point, forming in conjunction with water similar aqueous sand body in the step (2)
B。
Freeze pipe diameter in the step (4) less than casing diameter.
Annular gap space is formed between the freezing pipe and casing, and cement grout C is injected in the space of annular gap.
The cement grout C has the characteristics that be unable to thermal insulation.
The beneficial effects of the present invention are:
The present invention uses the freezing pipe more professional, more advanced frozen construction technique beats outer case sleeve into the mine borehole wall,
Has the effect of higher construction level and excellent.
Detailed description of the invention
Fig. 1 is the connection figure of casing of the present invention Yu the upper borehole wall；
Fig. 2 is that casing of the present invention penetrates borehole wall slip casting figure into pit shaft；
Fig. 3 is that casing of the present invention penetrates lower borehole wall figure；
Fig. 4 is casing of the present invention and freezes pipe diameter comparison diagram.
Specific embodiment
With reference to the accompanying drawing and specific embodiment the present invention is described in detail.
The present invention provides a kind of freezing pipes of outer case sleeve to wear slopes wall construction method, the specific steps of which are as follows:
(1) with the drill bit of outer case sleeve from ground tunneled downwards to slopes wall top wall surface, by casing to casing with
Casing and borehole wall upper surface are secured together (such as 1 institute of attached drawing by cementing slurries A in the borehole wall contact position when cement grout A solidification
Show).
Cement grout A needs to have a characteristic that setting time is short, bond strength is high, waterproof performance is good, leakproofness is strong.
(2) more bit change continues to tunnel, and penetrates borehole wall upper wall, by casing into pit shaft cementing slurries B (such as attached drawing 2
It is shown).
At this moment cement grout B needs used, which have a characteristic that, not to be changed freezing point, is formed with water in conjunction with and similar to contain water sand
The soil body.
Because of water burst sand leakage in pit shaft, water content is more, and when the later period applies construction freezing method, what water congeals into ice is strong
Degree is less than the intensity that frozen soil is formed after aqueous sand freezes, and is unsatisfactory for the demand for security of construction, therefore needs through casing to pit shaft
Interior cementing slurries reduce the content of water in pit shaft, it is ensured that freeze rear intensity and meet the requirements.
(3) continue driving to borehole wall wall surfaces, after penetrating the lower borehole wall, it is (such as attached that casing is fixed to borehole wall lower wall bottom end
Shown in Fig. 3).
(4) after the completion of the conduit crossing borehole wall, freezing pipe is placed in casing, and cement is injected between casing and freezing pipe
Slurries C (as shown in Fig. 4).
It due to freezing pipe diameter less than casing diameter, therefore will form annular gap space between freezing pipe and casing, need
This annular gap is filled up to fixed freezing pipe, therefore, it is necessary to the cementing slurries C in this annular gap.
Cement grout C in the step, which has a characteristic that, is unable to thermal insulation.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
