Description
Technical field
The utility model relates to construction of tunnel guarded drainage construction technology, is specifically related to the drainage system of ditch, side, anti-tunnel bottom leaky.
Background technology
The bottom surface in the ditch, side in existing tunnel generally higher than or flush in the end face of inverted arch packed layer, because constructed and the own shrinkage of concrete etc. affects, between the bottom surface in ditch, side and the end face of inverted arch packed layer, easily define longitudinal constuction joint.After tunnel builds up, very easily there is percolating water phenomenon in the root in ditch, side, later regulation difficulty control greatly, for a long time without cease, security risk is high, economic and social benefits weight losses.
Therefore, be necessary to improve existing tunnel drainage system.
Summary of the invention
The purpose of this utility model is to provide the drainage system of ditch, side, a kind of anti-tunnel bottom leaky, can effectively avoid occurring longitudinal constuction joint between the bottom of trench in ditch, side and inverted arch packed layer end face, to eliminate lateral sulcus bottom leaky hidden danger.
In order to achieve the above object, the utility model provides the drainage system of ditch, side, a kind of anti-tunnel bottom leaky, comprise set gradually from tunnel base scar to road surface or orbital plane direction inverted arch preliminary bracing, inverted arch secondary lining, inverted arch packed layer and supercrust, the Central drain extended along tunnel longitudinal direction is provided with in inverted arch packed layer, the ditch, side extended along tunnel longitudinal direction is respectively equipped with in both sides, ditch, both sides is communicated with Central drain respectively by railway roadbed gutter, and its key is: the bottom surface in ditch, both sides is all lower than the end face of inverted arch packed layer.
Be interval with discharge pressure pipe in the below of Central drain along tunnel longitudinal direction, the upper end of described discharge pressure pipe is communicated with Central drain, and the lower end of discharge pressure pipe is successively through inverted arch packed layer, inverted arch secondary lining, inverted arch preliminary bracing being communicated with tunnel base scar.Tunnel Central drain is communicated with tunnel base scar by discharge pressure pipe, forms drainage channel.When lining concrete ponding behind to collect at the bottom of tunnel and produces hydraulic pressure, overstocked moisture district can be disposed in tunnel Central drain, thus efficiently solve inverted arch constuction joint seepage problem.
The upper end of described discharge pressure pipe is communicated with Central drain and stretches in Central drain, and the lower end of discharge pressure pipe passes perpendicularly through inverted arch packed layer, inverted arch secondary lining, inverted arch preliminary bracing being communicated with tunnel base scar successively.
The beneficial effects of the utility model are:
(1) the bottom surface absolute altitude in ditch, both sides in tunnel is reduced to below the end face of inverted arch packed layer, can effectively avoids occurring longitudinal constuction joint between the bottom of trench in ditch, side and inverted arch packed layer end face, to eliminate lateral sulcus bottom leaky hidden danger.
(2) in the below of Central drain, discharge pressure pipe is set along longitudinal direction interval, tunnel, tunnel Central drain is communicated with tunnel base scar, form drainage channel.When lining concrete ponding behind to collect at the bottom of tunnel and produces hydraulic pressure, overstocked moisture district can be disposed in tunnel Central drain, thus efficiently solve inverted arch constuction joint seepage problem.
(3) the utility model has the advantages such as little, easy and simple to handle, the required plant equipment of construction interference is simple and easy, cost input is low, effectively can solve the leakage problems of ditch, both sides, tunnel root.Control high economic cost, prestige cost and the high-level security risk of oozing leak stopping after decreasing tunnel operation, remarkable in economical benefits, social benefit is given prominence to, practical, has good popularization, using value, good development prospect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The drainage system of ditch, side, anti-tunnel bottom leaky as shown in Figure 1, comprise the inverted arch preliminary bracing 2 set gradually to road surface or orbital plane 10 direction from tunnel base scar 1, inverted arch secondary lining 3, inverted arch packed layer 4 and supercrust 5, the Central drain 8 extended along tunnel longitudinal direction is provided with in inverted arch packed layer 4, the ditch, side 6 extended along tunnel longitudinal direction is respectively equipped with in the both sides of supercrust 5, ditch, both sides 6 is communicated with Central drain 8 respectively by railway roadbed gutter 7, railway roadbed gutter 7 is laterally located in inverted arch packed layer 4, one end of railway roadbed gutter 7 is communicated with the sidewall of Central drain 8, the other end of railway roadbed gutter 7 is upwards communicated with the sidewall in ditch, side 6 by elbow.The bottom surface 6a in ditch, both sides 6 is all lower than the end face 4a of inverted arch packed layer 4.
In inverted arch packed layer 4 work progress, behind unwrapping wire location, mounting edge mould concreting, the bottom surface 6a in ditch, both sides 6 is down to below the end face 4a of inverted arch packed layer 4, reduce and highly can refer to the rich water yield size in tunnel, but unsuitable too high, avoid between the bottom surface 6a and the end face 4a of inverted arch packed layer 4 in ditch, both sides 6, forming longitudinal constuction joint, to eliminate lateral sulcus root hidden leakage defect.
As shown in Figure 1, in the below of Central drain 8, discharge pressure pipe 9 is set along longitudinal direction interval, tunnel, the upper end of discharge pressure pipe 9 is communicated with Central drain 8 and stretches in Central drain 8, the lower end of discharge pressure pipe 9 passes perpendicularly through inverted arch packed layer 4, inverted arch secondary lining 3, inverted arch preliminary bracing 2 being communicated with tunnel base scar 1 successively, when lining concrete ponding behind to collect at the bottom of tunnel and produces hydraulic pressure, overstocked moisture district can be disposed in tunnel Central drain 8 by discharge pressure pipe 9, then is drained into outside tunnel by Central drain 8.
In inverted arch preliminary bracing 2, inverted arch secondary lining 3, inverted arch packed layer 4 work progress, the center line in tunnel to keep at a certain distance away a pre-buried discharge pressure pipe 9 along tunnel longitudinal direction, makes to form drainage channel between Central drain 8 and tunnel base scar 1.After discharge pressure pipe 9 is provided with, the mouth of pipe should to stretch in Central drain 8 and higher than the flowing water face in Central drain 8.Discharge pressure pipe 9 gradation connects the modular connection adopting corresponding model, and setting space is determined according to the rich water yield size in tunnel.
The utility model is applicable to general tunnel, is specially adapted to rich water tunnel.Be more than better embodiment of the present utility model, all do within spirit of the present utility model and principle any amendment, equivalent replace and improve all should be included within protection domain of the present utility model.
