Abstract
The utility model provides a kind of tunnel draining blind pipe, at water outlet design and installation telescopic pipe of blind pipe, for piling up the sandstone mud in blind pipe in massif flowing water.By pulling off sleeves pipe, it is cleared up, can prevent sandstone mud pile up cannot clear up and cause draining blind pipe blocking.
Description
Technical field
The utility model relates to the realm of building construction, particularly a kind of measurement mechanism measuring water level in sedimentation basin.
Background technology
In the building-up work in tunnel, need to arrange many tunnel draining blind pipes, for massif flowing water is drained into sewer along an arch ancient piece of jade, round, flat and with a hole in its centre in tunnel body of wall.Existing tunnel construction drainage plant be one group containing the soft draining blind pipe being uniformly distributed permeable aperture, the two ends outlet of water pipe is respectively at two side bottoms of tunnel camber arch, enter in water pipe to facilitate massif flowing water by permeable aperture, sewer is flowed out in pipe, and often containing sandstone mud in massif flowing water.The subject matter of prior art is, owing to containing a certain amount of sandstone mud in massif flowing water, thus the phenomenon that often easily results in blockage in the position of blind pipe delivery port, and be often difficult to operation cleaning difficulty by the mode of disclosing stamp and easily damage water pipe.
Summary of the invention
For above-mentioned defect, the purpose of this utility model be to provide one can easy cleaning draining blind pipe delivery port sandstone mud, the tunnel draining blind pipe of infringement body when preventing mouth of pipe clogging and prevent from removing the mouth of pipe.
To achieve these goals, the utility model provides a kind of tunnel draining blind pipe, comprises blind pipe and telescopic pipe, and telescopic pipe is nested to be installed in blind pipe outlet, and telescopic pipe has exposed parts relative to blind pipe mouth end face.From such scheme, when the sandstone mud in massif flowing water arrives blind pipe exit, can accumulate in telescopic pipe, dismounting is cleared up, and can reach the effect preventing from blocking.
More concrete scheme is, telescopic pipe exposed junction arranges the shaft shoulder.From such scheme, utilize the shaft shoulder can more convenient dismounting and cleaning, the large 10-20mm of shaft shoulder external diameter comparable blind pipe diameter dimension.
Preferably, the nested mounting means be installed in blind pipe of telescopic pipe adopts interference fits.From above scheme, telescopic pipe can be made so not easily to come off due to the thrust of sandstone mud, also can not be difficult to dismounting because of cooperation tension simultaneously.
Preferably, telescopic pipe body one end is greater than 45 degree of chamfered.From above scheme, when sandstone mud arrives blind pipe outlet with flowing water, sandstone mud can guide in telescopic pipe by interior chamfering more easily.
Preferably, telescopic pipe wall thickness gets 2-5mm.Sleeve adopts the thickness of thinner tube wall to be guided in telescopic pipe by sandstone mud more easily.
Preferably, telescopic pipe inwall whole installation tapering 5-30 degree.From above scheme, telescopic pipe inwall whole installation tapering is convenient to sandstone mud and is entered in telescopic pipe.
Preferably, bobbin inwall arranges arc from interior to end face.From above scheme, the inwall of arc line shaped sandstone mud of being more convenient for enters in telescopic pipe.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
First embodiment:
As depicted in figs. 1 and 2, draining blind pipe in tunnel is made up of blind pipe 1 and telescopic pipe 2, and the revealed section of telescopic pipe has the shaft shoulder 21 of external diameter 10-20mm larger than blind pipe 1 diameter dimension.Telescopic pipe 2 is installed in blind pipe 1 ordinatedly with embedded mode hole axle, and fit system takes interference fits.The sandstone mud of massif flowing water moves downward from blind pipe body 11, is finally deposited in the telescopic pipe 2 of blind pipe mouth 12, and the shaft shoulder 21 of telescopic pipe 2 makes it dismantle extraction more easily, and telescopic pipe 2 is taken apart from blind pipe 1, then clears up telescopic pipe 2.
Second embodiment:
The structure of the present embodiment and the similar of the first embodiment, difference is telescopic pipe inwall is provided with chamfering.
As shown in Figure 3, the shaft shoulder 21 of the external diameter 10-20mm larger than blind pipe 1 diameter dimension that the revealed section of telescopic pipe 2 has, telescopic pipe 2 embedded hole axle coordinates and is installed in blind pipe 1, and fit system takes interference fits.Sleeve body 22 inwall one end arranges 75 ° of chamferings.The sandstone mud of massif flowing water down moves from blind pipe 1, finally be deposited in the telescopic pipe 2 of blind pipe mouth 12, the shaft shoulder 21 of telescopic pipe 2 makes it dismantle extraction more easily, telescopic pipe 2 is taken apart from blind pipe 1, again telescopic pipe 2 is cleared up, and sandstone mud can guide in telescopic pipe 2 by the interior chamfering of sleeve body 22, accumulation effect is better.
3rd embodiment:
The structure of the present embodiment and the similar of the first embodiment, difference is that the inwall of telescopic pipe is thinner.
As shown in Figure 4, the revealed section of telescopic pipe 2 has the shaft shoulder 21 of external diameter 10-20mm larger than blind pipe 1 diameter dimension.The axle cooperation of telescopic pipe 2 embedded hole is installed in blind pipe 1, and fit system takes interference fits.Sleeve body 22 thickness is set to 2-5mm, such as, can be 3mm.The sandstone mud of massif flowing water down moves from blind pipe, is finally deposited in the telescopic pipe 2 of blind pipe mouth 12, and the shaft shoulder 21 of telescopic pipe 2 makes it dismantle extraction more easily, and telescopic pipe 2 is taken apart from blind pipe 1, then clears up telescopic pipe 2; And sleeve body 22 thickness is only 3mm, thinner thickness can play and help sandstone mud to enter in telescopic pipe 2, and don't can cause the defect of body strength deficiency because of too thin.
4th embodiment:
The structure of the present embodiment and the similar of the first embodiment, difference is that telescopic pipe inwall is taper surface.
As shown in Figure 5, the revealed section of telescopic pipe has the shaft shoulder 21 of external diameter 10-20mm larger than blind pipe 1 diameter dimension.The axle cooperation of telescopic pipe 2 embedded hole is installed in blind pipe 1, and fit system takes interference fits.Sleeve body 22 inwall arranges overall tapering 15 degree of-30 degree.The sandstone mud of massif flowing water down moves from blind pipe, is finally deposited in the telescopic pipe 2 of blind pipe mouth 12, and the shaft shoulder 21 of telescopic pipe 2 makes it dismantle extraction more easily, and telescopic pipe 2 is taken apart from blind pipe 1, then clears up telescopic pipe 2; And sleeve body 22 inwall arranges tapering, can make interior to face area reduce, the barrier effect of end face to the motion of sandstone mud can be greatly reduced, sandstone mud is guided in telescopic pipe 2, pile up effect better.
5th embodiment:
The structure of the present embodiment and the similar of the first embodiment, difference is that telescopic pipe inwall is set to arcwall face.
As shown in Figure 6, the revealed section of telescopic pipe 2 has the shaft shoulder 21 of external diameter 10-20mm larger than blind pipe 1 diameter dimension.The axle cooperation of telescopic pipe 2 embedded hole is installed in blind pipe 1, and fit system takes interference fits.Sleeve body 22 inwall is set to arcwall face.The sandstone mud of massif flowing water down moves from blind pipe, is finally deposited in the telescopic pipe 2 of blind pipe mouth 12, and the shaft shoulder 21 of telescopic pipe 2 makes it dismantle extraction more easily, and telescopic pipe 2 is taken apart from blind pipe 1, then clears up telescopic pipe 2; And sleeve body 22 inwall is set to arcwall face, round and smooth cambered surface can reduce the obstruction to sandstone mud movement, guides in telescopic pipe 2 better by sandstone mud, and accumulation effect is better.
