Description
Technical field
The utility model relates to the structure of a kind of tunnel under water seepage treatment, belongs to Hydraulic and Hydro-Power Engineering technical field.
Background technology
In the industries such as water conservancy, mine, traffic; often bury in underground deep in tunnel; may also there is the building of paddling such as river or reservoir in top, some tunnels; especially karst area; longer tunnel often can be subject to infiltration impact along the line; under certain head effect, even also may cause water inrush accident, thereby cause the loss of lives and properties.Therefore, seem particularly important for the seepage treatment in tunnel under water.Conventional treatment method, is mainly to set about from inside, tunnel processing, and carries out concrete lining and grout sealing processing along the line in inside, tunnel; But when it is implemented, the production run in tunnel will be produced to larger interference, even if along the line layout the in tunnel carried out relocating temporarily or forever, all will affect largely its normal production run and efficiency, the long period stopping production that even needs having could meet the requirement of engineering processing.
Utility model content
The purpose of this utility model has been to provide a kind of seepage treatment structure of tunnel under water, when this structure is implemented, can not produce larger interference to the production run in tunnel, can overcome the deficiencies in the prior art.
The utility model is achieved by following technical solution:
The utility model has adopted the structure of such seepage treatment of tunnel under water, is mainly grouting tunnel and seepage proof curtain that above Ji tunnel, tunnel, outside certain distance, both sides (being corner with tunnel) are arranged.Grouting tunnel is parallel to tunnel axis, is arranged in the arranged on left and right sides top in tunnel, and tunnel pushes up the minimum over burden of above rock mass and should determine according to factor analyses such as landform, geological conditions, supporting types; Rock mass thickness between grouting tunnel and tunnel should meet the requirement of structure and antiseepage, through comprehensive Analysis deterrmination, should not be less than 2 times of grouting footpaths, tunnel excavation hole (or hole is wide).
In addition, grouting tunnel, when by tunnel seepage treatment section, need carry out reinforced concrete lining layer and consolidation grouting processing; Grouting tunnel, process seepage section hole section in addition by tunnel, can unite two into one, and adopts a grouting tunnel to pass to mouth hanging place.The upper and lower cross-lapping sealing of seepage proof curtain, seals tunnel surrounding completely, blocks underground water or storehouse seepage passage.
The beneficial effects of the utility model are:
Compared with prior art, the utility model arranges grouting tunnel by both sides above tunnel, to the seepage proof curtain of the upper and lower cross-lapping of tunnel peripheral disposition, tunnel seepage section is all sealed wherein, block the passage of Shui Xiang tunnel, storehouse seepage, thereby reach the object of leakage blocking and seepage-proofing.Compared with the method is carried out seepage treatment scheme with traditional inside, tunnel, avoid interference and the influence on system operation of construction period to tunnel production, construction difficulty is less simultaneously, ensure antiseepage treatment effect, and possess further treatment conditions of later stage, also be economically viable, there is significant economic benefit and social benefit.
brief description of the drawings
Fig. 1 is floor map of the present utility model;
Fig. 2 is schematic cross section of the present utility model.
Description of reference numerals: 1-tunnel, the 2-tunnel that is in the milk, 3-seepage proof curtain.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 2, the utility model is that grouting tunnel 2 is set in 1 both sides, tunnel, and constructs at the seepage proof curtain 3 that upper and lower cross-lapping is carried out in grouting in tunnel 2, and seepage proof curtain 3 is by tunnel 1 surrounding sealing.
As shown in Figure 2, two grouting tunnels 2 are arranged in 1 top, both sides, tunnel, and grouting tunnel 2 holes are pushed up the minimum over burden of above rock mass and should be determined according to factor analyses such as landform, geological conditions, supporting types; Rock mass thickness between grouting tunnel 2 and tunnel 1 should meet the requirement of structure and antiseepage, through comprehensive Analysis deterrmination, should not be less than the footpath, excavation hole (or hole is wide) of 2 times of grouting tunnels 2; Grouting tunnel 2 need carry out concrete lining and consolidation grouting processing by the hole section of tunnel 1 seepage section.
As shown in Figure 1, grouting tunnel 2 is parallel to tunnel 1 to be arranged, grouting tunnel 2, process seepage section hole section in addition by tunnel 1, can unite two into one, and adopts a grouting tunnel 2 to pass to mouth hanging place.
The section configuration of grouting tunnel 2 is gateway opening shape, and cross dimensions is to meet curtain grouting and transport need is advisable; Grouting tunnel 2 base slopes adopt along slope, are beneficial to hole internal drainage.
Curtain grouting scope should be determined according to tunnel geological conditions along the line, rationally determine grouting parameter and the grouting process such as grouting row, pitch-row, hole deviation, the degree of depth in conjunction with grouting test, and detect grouting effect by various detection means, require upper and lower seepage proof curtain 3 to seal by cross-lapping, ensure the validity of anti-seepage effect.
As shown in Figure 1 and Figure 2, enforcement of the present utility model is mainly carried out in accordance with the following steps:
The first step, according to the scope of tunnel 1 and seepage treatment section thereof, first determines mouth hanging position, layout circuit, elevation, the axis of grouting tunnel 2, then completes tunnel excavation and supporting;
Second step, carries out reinforced concrete lining layer and consolidation grouting processing in the hole section at grouting tunnel 2 by tunnel 1 seepage section;
The 3rd step is carried out the seepage proof curtain 3 of upper and lower cross-lapping and is constructed in grouting tunnel 2, and seepage section tunnel 1 is all sealed;
The 4th step, carries out all kinds of detections to seepage proof curtain 3 implementation results, according to detection case, carries out if desired the supplementary grouting of corresponding site and processes and inspect for acceptance.
Certainly, be more than concrete exemplary applications of the present utility model, the utility model also has other embodiment, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, within all dropping on the desired protection domain of the utility model.
