Domain.
Background technique
Current city track traffic engineering development scale is increasingly rapider, grows, for construction enterprises, competitive pressure
Also increasing, civilized construction requires also higher and higher.The particularity of present city track traffic engineering itself, engineering one
As in the city, edge, even in sensitive areas such as urban center, residential blocks, it is brought the result is that bored tunnel
Shared engineering ratio is gradually improving, and is the essential a part of city track traffic engineering.Everybody is it is well known that tunneling tunnel
Road is risk highest in underground engineering, the engineering that difficulty of construction is maximum, underground water is most.The presence of underground water, not only increases
The security risk during tunnel excavation is added, and but also ponding is more at excavation face, civilized construction is very poor.Traditional
Draining way is that plash is dug in side of keeping to the side near face on the spot, and water is pooled in hole, with the artificial pump drainage one by one of water pump
To outside hole.This way there are the shortcomings that it is as follows: (1) plash capacity is limited, pump drainage not in time in the case where be easy cross flow extremely
Hole is outer, and dewatering effect is poor；(2) cutting depth is shallower (hole bottom is higher than inverted arch bottom) under normal conditions for plash, can only collect ground
Face diameter flowing water, cannot reduce the following water level in inverted arch face, and civilized construction effect is poor；(3) hole internal water accumulation uses artificial pump drainage, is drawing water
Internal water accumulation cannot be cheated under the conditions of number is limited in time, influences civilized construction in hole.
Utility model content
In order to solve the problems, such as background technique, the utility model is by the control of buoy, and water pump opens automatically in well
Move and draw water, realize the lifting of Tunnel inner product water cascade, pump drainage step by step, outside final pump drainage to hole so that hole internal water accumulation pump drainage and
When, dewatering effect is obvious, drying is kept in hole, safety, civilized construction meet construction demand in hole.
In order to solve the problems, such as background technique, to solve the above problems, the utility model passes through following technical side
Case is realized:

Offer the filtration hole of 20@200*200mm of Ф.
Preferably, the rubble loaded filter with a thickness of 10cm is equipped on the outside of the dewatering well.
Preferably, the draw water pipeline uses diameter to manage for the PE of Ф 100mm.
Preferably, the buoy mounting height should be no less than 1m away from precipitation bottom.
Preferably, the dewatering well elevation of bottom backfills face absolute altitude 50cm lower than inverted arch.
The utility model has the following beneficial effects:
1. dewatering well elevation of bottom is lower than tunnel inverted arch absolute altitude, earth's surface ponding below, dewatering effect can be preferably collected
Obviously.Especially in V, VI grade country rock section of rich groundwater, the not only ponding at pump drainage inverted arch, and reduce near face
Water level, excavate it is safer.
2. in inverted arch side by being equally spaced in dewatering well, and it is mounted with buoy, it can be achieved that step, automation draw water,
Keep safety construction demand in hole.
3. installing buoy in well, automation of drawing water, tunnel excavation construction period, pump drainage water running cost of labor is lower, warp
Benefit of helping and social benefit are obvious.
4. installing dewatering well in inverted arch side, not only realizes and takes out drainage effect in hole, can also be achieved the dewatering effect in hole,
And dewatering well does not influence traffic passage demand in hole in inverted arch avris.
5. automation water plug not only plays pump drainage water, dewatering effect during tunnel excavation, but also applies in two linings
Between duration, dewatering effect can be still played, is played a key effect to two lining construction qualities.
