Description
Technical field
It the utility model is related to a kind of borehole sealing device, more particularly to a kind of portable underwater drilling quick plugging device.
Background technology
Under water during tunneling, it is often necessary to carry out prospecting by boring in advance.Although, it is necessary to block in time after prospecting by boring
Drilling, but often due to closure difficulty, causes many drillings not block substantially.When submerged tunnel is built, tunnel upper is existing
Geotechnical boring is permeable, inevitably results in tunnel water bursting factor, influences construction safety and from now on tunnel operation security, influences tunnel
Road engineering Function.
A series of problems be present when blocking underwater drilling in the past：(1) plugging material is cement mortar, and cement mortar can not
Orifice position is directly reached, even if having arrived orifice position, cement mortar is quickly spread in water, and aperture can not be blocked；
(2) as added set accelerating additive in cement mortar, then cement mortar is not arrived to orifice position also and just solidified, and does not reach closure
Effect；(3) once the closure failure of existing geotechnical boring, the existing geotechnical boring of tunnel upper is permeable, inevitably results in tunnel
Water bursting factor, construction safety and from now on tunnel operation security are influenceed, influence Tunnel Engineering Function.It must block again, into
This is very high.
Generally speaking, portable, quick blocking is the basic method of underwater existing geotechnical boring closure.Once had both at home and abroad underwater
The report of existing geotechnical boring cement mortar closure.The method of this underwater existing geotechnical boring cement mortar closure, on the one hand
Do not solve root problem, cement mortar quickly spreads in water, can not realize quick blocking；On the other hand, such as cement mortar
Middle addition set accelerating additive, then cement mortar do not arrive to orifice position also and just solidified, do not reach plugging effect.
Utility model content
The purpose of this utility model is to provide a kind of portable underwater drilling quick blocking simple in construction, operational security
Device, the problem of to overcome existing underwater existing borehole sealing difficulty.
In order to solve the above technical problems, portable underwater drilling quick plugging device provided by the utility model, including under
Sinker, internal air bag and gas tube filled with consolidation powder, the lower sinker bottom are provided with burst-chamber, and upper end is provided with suspension rope
Rope, the lower sinker upper end are communicated with the perforation of the burst-chamber, described gas tube one end passed from the perforation and with
The air bag connection, so as to which the air bag is suspended in the burst-chamber, the other end is connected with gas cylinder.
Further, the first fixation plug and second is installed with the gas tube and fixes plug, described first fixes plug
On the upper surface of the perforation, described second fixes plug on the lower end of the perforation, fixes and fills in by described first
Plug is fixed with second the gas tube is clamped on the lower sinker.
Further, a pair of connecting hooks are symmetrically installed with the lower sinker upper surface, are installed respectively in the connecting hook
There is the suspension rope.
Further, the diameter of the burst-chamber is more than or equal to the diameter of underwater drilling.
Further, the gas tube is provided with control valve.
Further, the suspension rope needs length adjustable according to actual condition.
In use, portable underwater drilling quick plugging device, then under gravity, portable underwater are installed first
Drilling quick plugging device sinks to the bore position detected in advance by rope, gas tube and gas cylinder is connected, to high pressure gas
Cylinder is inflated, and is expanded after airbag aeration, and when air pressure is more than 0.2Mpa in air bag, air bag explodes, consolidation powder and aquatic products in air bag
Biochemical reaction, 1-2 quickly solidify after minute, realize that hell envelope is quick stifled, rope is lifted into recovery together with gas tube, changed
After air bag, it can reuse.
The utility model has the characteristics of simple in construction, easy to operate, can quickly and easily block underwater drilling.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As Figure 1-3, portable underwater provided by the utility model drilling quick plugging device, including it is lower sinker 1, interior
Air bag 2 and gas tube 3 of the portion filled with consolidation powder, the consolidation powder is powdery hydraulicity inorganic coagulation material, the lower sinker 1
It is made up of prefabricated reinforced concrete block and built-in iron wire skeleton, its bottom is provided with burst-chamber 4, and one is symmetrically installed with upper surface
To connecting hook 5, suspension rope 6 is separately installed with the connecting hook, the suspension rope 6 needs length according to actual condition
Adjustable, the lower upper end of sinker 1 is communicated with the perforation 7 of the burst-chamber 4, and described one end of gas tube 3 is worn from the perforation 7
Go out and be connected with the air bag 2, so as to which the air bag 2 is suspended in the burst-chamber 4, the other end is connected with gas cylinder 8,
Specifically, the first fixation plug 9 and second is installed with the gas tube 3 fixes plug 10, described first, which fixes plug 9, is located at institute
On the upper surface for stating perforation 7, described second fixes plug 10 on the lower end of the perforation 7, is fixed by described first and fills in 9 Hes
