Description
Technical field
The present invention relates to tunnel construction field more particularly to a kind of railway tunnel basement rock working face processing methods.
Background technique
With the continuous reinforcement of national basis Facilities Construction dynamics, various tunnel construction engineering quantities also gradually increase, phase
It answers, the quantity, scale and type about tunnel structure disease are also in rising trend.Wherein, railway tunnel structure is main
Disease includes: that lining cutting percolating water, Lining cracks and bottom structure damage, ratio account for about the 97% of all diseases, wherein tunnel
Bottom structure Damage Types again can there are many, such as shop fixtures is destroyed, is risen soil, lateral sulcus breakage, in order to reduce such disease
The probability of generation should first ensure that the quality that performs of concrete structure meets design requirement.
And during the tunneling of region of FuShui, tunnel bedrock surface is easy to appear some EXIT POINTs, even if taking
Rational approach still suffers from some residual water and exists, and the operation process of construction personnel mixes residual water with void quarrel, makes bedrock surface
Miriness can't bear, and in loess geologic province, this phenomenon is especially serious, not only make troubles to construction operation, and cleaning work is also very
It is difficult, it does not do cleaning such as before concrete work or cleaning is not in place, bigger harm will be generated, for example, water on bedrock surface
Presence change the ratio of mud of concrete, the increase of the ratio of mud makes to be easy to produce minute crack in course of hardening, micro-
Small crack easily extension perforation under train load long duration of action, causes concrete self-waterproof ability defect occur, at tunnel bottom
Occur infiltration phenomenon under pressure water action, further results in concrete and carbonization and steel bar corrosion occurs, destroy the entirety of structure
Property and durability, generate a large amount of tunnel bottom structure diseases；Construction site working environment is severe, causes to the physical and mental health of construction personnel
Damage；Tunnel such as is built in region of FuShui, then country rock EXIT POINT is more, and construction personnel's operation and tunnel haulage transport are to continue
Process causes cleaning work large labor intensity and is not easy to carry out.
Therefore, it is necessary to provide a kind of new railway tunnel basement rock working face processing method, it can stablize and effectively protect
It is dry to hold tunnel surrounding basal plane, solves the problems, such as that existing tunnel country rock basal plane has residual water and miriness is unbearably brought.
Summary of the invention
The present invention is directed to above-mentioned the technical problems existing in the prior art, provides at a kind of railway tunnel basement rock working face
Reason method can keep tunnel surrounding basal plane dry, solve tunnel bottom bedrock surface in construction personnel's operating process due to miriness
Unbearably generated series of technical.
Used technical solution is as follows to solve above-mentioned technical problem by the present invention:
A kind of railway tunnel basement rock working face processing method is provided, is included the following steps:
S1, Railway Tunnel Surrounding Rock basal plane EXIT POINT is blocked；
S2, the ponding of the Railway Tunnel Surrounding Rock basal plane and empty quarrel are cleaned out；
S3, water-absorbent material is paved on the Railway Tunnel Surrounding Rock basal plane to adsorb residual ponding and keep drying；
S4, pave the dry working face for gathering materials, forming drying and hardening on the water-absorbent material.
Preferably, further include S5, it is described it is dry gather materials on successively perform preliminary bracing and secondary liner structure.
Preferably, in step S3, the water-absorbent material is quick lime.
Preferably, the quick lime with a thickness of 10-30cm.
Preferably, described dry to gather materials according to parts by weight in step S4, comprising: 20-45 parts of cement, 10-25 parts of rubbles with
And 20-30 parts of sand.
Preferably, it is described it is dry gather materials with a thickness of 10-20cm.
Technical effect acquired by technical solution of the present invention is as follows:
(1) technical solution of the present invention is different from the measure passively cleared up in present scheme, and water can be made to become basal plane
The advantage of hardening can guarantee the drying of tunnel bottom structure construction work surface, not only provide hardening for construction personnel
Working face, it is ensured that the drying of operation side has completely cut off the straight of construction personnel, instrument and haulage vehicle and tunnel bedrock surface
Contact thereby ensures that going on smoothly for concreting work；
(2) generation for having prevented operation side miriness phenomenon hence improves the working environment of construction personnel；
(3) cleaning work for reducing bedrock surface reduces the working strength of construction personnel.
(4) use material be easy obtain and it is low in cost；And construction method process is simple and easy to do, to the skill of operator
Art Capability Requirement is low.
Detailed description of the invention
To describe the technical solutions in the embodiments of the present invention more clearly, make required in being described below to embodiment
Attached drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for
For those of ordinary skill in the art, without creative efforts, it can also be obtained according to these attached drawings other
Attached drawing.
Fig. 1 is the flow chart of railway tunnel basement rock working face processing method in the embodiment of the present invention one；
Fig. 2 is the structural schematic diagram of railway tunnel basement rock working face in the embodiment of the present invention one.
Specific embodiment
The present invention is easy to appear ponding for tunnel bedrock surface existing in the prior art, leads to the operation of construction personnel
Journey mixes residual water with void quarrel, and bedrock surface miriness is caused to can't bear, and further results in construction operation difficulty, influences concrete structure
The problem of quality, provides a kind of railway tunnel basement rock working face processing method, and core concept is: in Railway Tunnel Surrounding Rock
Pave water-absorbent material on basal plane, such as quick lime ponding and keeps drying to adsorb residual；Further on the water-absorbent material
Pave the dry working face for gathering materials, forming drying and hardening, and thus solves tunnel bottom bedrock surface in construction personnel's operating process
