Abstract
The utility model provides a deep basal pit pressure -bearing water precipitation gas well gas bag plugging device, belongs to mine safety construction technical field, including a plurality of concrete pumping pipes, and characterized in that, concrete pumping pipe between be provided with gasbag plugging device, gasbag plugging device including the first fixed plate and second fixed plate, the first fixed plate with the second fixed plate between with the concrete pumping pipe is provided with a plurality of gasbag for the even circumference in center, the gasbag on be provided with miniature relief valve, miniature relief valve be in the first fixed plate top. Compared with the prior art, the beneficial effects of the utility model are that: this device has a plurality of gasbag, passes through mutual extrusion this device of reinforcing and the frictional force between the wall of a well between gasbag and the wall of a well soil at shutoff relief well's in -process for relief well can not extruded by the water under high pressure to the slip casting thing, makes this device can the safe quick closed relief well who floods appear.
Description
Technical field
The utility model belongs to mine safety technical field of construction, especially deep foundation ditch artesian water dewatering well shutoff utensil.
Background technology
In infrastructure and production (as subway work, underground mining etc.) process, a large amount of relief wells can be built and carry out draining to prevent generator tube from gushing or other geological disasters.Because the surface water and underground water pour in relief well by various passage, make the water yield in relief well very abundant, water yield of well can reach 60m
3/ h, have a power failure or fault of water pump if occur, artesian water is general on fountain shape, causes a large amount of ponding of foundation ditch, when relief well water burst exceedes proper drainage ability, because well head diameter is large, the degree of depth is large, catchment area is large, can directly cause water level to go up rapidly.Usually with the mode placement in layers medium sand of shutoff drainage well with topple over high-strength quick-solidifying concrete in well when running into this situation, but due to head pressure large, in well, water overflows in a large number, and relief well can cause relief well floods by outside part medium sand and concrete top to well.
Utility model content
The utility model is for deficiency of the prior art, provide a kind of deep foundation ditch artesian water dewatering well air bag plugging device, this device has several air bags, extrude by mutual between air bag and the borehole wall soil frictional force strengthened between this device and the borehole wall in the process of shutoff relief well, make slip casting thing can not be extruded relief well by water under high pressure, make this device can the closed relief well occurring floods safely and fast.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of deep foundation ditch artesian water dewatering well air bag plugging device, comprise some concrete pumping pipes, it is characterized by, air bag plugging device is provided with between described concrete pumping pipe, described air bag plugging device comprises first fixed head and second fixed head, between described first fixed head and described second fixed head, centered by described concrete pumping pipe, uniform circular is provided with several air bags, described air bag is provided with miniature relief valve, described miniature relief valve is in above described first fixed head.
In technique scheme, preferably, the described concrete pumping pipe being in lowermost end is provided with positioning anchor.
In technique scheme, preferably, described air bag is provided with several protruding.
In technique scheme, preferably, described concrete pumping pipe is provided with leakproof sleeve pipe.
All generally by living relief well injecting quick-drying concrete enclosing in concrete pumping pipe feeding relief well after relief well generation floods, but part concrete can be depressurized Jing Neigaoyashui and again ejects when injection, make insufficient infusion, extend the time of relief well sealing greatly, more likely cause relief well to seal unsuccessfully.This device arranges air bag plugging device between two concrete pumping pipes, the air bag extend on relief well relief air bag plugging device at concrete pumping pipe fully contacts with relief well inwall, now between air bag and relief well inwall, there is great frictional force, whole device stablizing in relief well can be ensured.During slip casting, partial high pressure current can between air bag or flow away between air bag and inwall, and discharge partial pressure in relief well, the concrete squeezed out then can be blocked by air bag, stays in relief well.Again because frictional force huge between air bag and inwall can prevent water under high pressure from whole device is gone out relief well, concrete is squeezed outpour after can stay in relief well and carry out fast condensing thus sealing up relief well.If relief well water flow pressure is huge, strong impact is caused to air bag, air bag is crushed in order to prevent High-Pressure Water, also on air bag, be provided with miniature relief valve, just automatically open when the pressure in air bag acquires a certain degree, partial pressure in release air bag, prevents balloon rupture from occurring space thus allows concrete be discharged relief well by High-Pressure Water from space.
Compared with prior art, the beneficial effects of the utility model are: this device has several air bags, extrude by mutual between air bag and the borehole wall soil frictional force strengthened between this device and the borehole wall in the process of shutoff relief well, make slip casting thing can not be extruded relief well by water under high pressure, make this device can the closed relief well occurring floods safely and fast.
Accompanying drawing explanation
Fig. 1 is the utility model perspective diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
As shown in Figure 1, a kind of deep foundation ditch artesian water dewatering well air bag plugging device, comprises some concrete pumping pipes 1, described concrete pumping pipe 1 is provided with leakproof sleeve pipe 3.The described concrete pumping pipe 1 being in lowermost end is provided with positioning anchor 4.Air bag plugging device 2 is provided with between described concrete pumping pipe 1, described air bag plugging device 2 comprises first fixed head 21 and second fixed head 22, between described first fixed head 21 and described second fixed head 22, centered by described concrete pumping pipe 1, uniform circular is provided with several air bags 23, described air bag 23 is provided with several projections.Described air bag 23 is provided with miniature relief valve 24, and described miniature relief valve 24 is in above described first fixed head 21.
During use, whole device is inserted in relief well, tentatively fixed by positioning anchor 4, generally speaking can extend into after in relief well at device and again air bag 23 be inflated, make air bag 23 fully touch relief well inwall and fix further under frictional force between air bag 23 and relief well inwall.Then allow concrete be injected in relief well by nozzle 22, because air bag 23 must stop, concrete can not allow water under high pressure take out of outside relief well, but stays in relief well, relief well can have been sealed up after certain hour concrete setting.If when squeezing concrete, decompression borehole pressure is excessive when will cause damage to air bag 23, miniature relief valve 24 releasing pressure automatically on air bag 23 ensures that air bag 23 does not break, and prevents concrete to run off.
