Abstract
The utility model discloses a construction adit sealing structure which comprises a construction adit, wherein the top and the bottom of the construction adit are connected with adit baffles; the two adit baffles are connected by virtue of a steel bar support column which is arranged in a manner of penetrating through the two adit baffles; an overhaul passage is arranged between the two adit baffles; the middle of the overhaul passage is provided with an access door; the access door passes through the middle of the overhaul passage and is connected with an arch-shaped sealing body; the side surface of the arch-shaped sealing body is provided with an upstream face; the upper and lower ends of the arch-shaped sealing body are supported on the adit baffles on the two sides; one side of the arch-shaped sealing body is connected with a sealing section; the sealing section is provided with a longitudinal section with two smaller ends and a larger middle; the sealing section is internally provided with a diversion tunnel; a press tunnel is formed between the arch-shaped sealing body and the diversion tunnel. The construction adit sealing structure is applicable to permanently sealing middle-head and low-head hydraulic tunnel construction adits or temporarily sealing a hydraulic tunnel master cave; the sealing construction workload is less, the sealing effect is good, and the risk of damage caused by water pressure can be effectively reduced.
Description
Technical field
The utility model relates to a kind of plugging structure, and particularly hole plugging structure is propped up in a kind of construction.
Background technology
The hole later stage is propped up in the construction of water conservancy project pressurized tunnel all needs to carry out shutoff, conventional occluding body arrangement is the whole fill concretes of a certain length hole section in a construction hole, utilize blocking concrete and diversion tunnel around friction and the bonding force opposing upper water pressure of rock, and be aided with the measures such as joint bar, consolidation grouting and backfill grouting.This shutoff mode exists certain problem, and the one, blocking concrete and the crown of diversion tunnel barrel and the adhesive effect of abutment wall are very not good, have larger potential safety hazard; The 2nd, adopt the length of this shutoff mode blocking concrete longer, engineering quantity is large, and cost of investment is high.The occluding body construction of construction hole is generally arranged in after hydraulic tunnel integral construction completes to be carried out, and need take the engineering straight line duration, and if routinely plug carry out shutoff, can strengthen later stage projects amount and difficulty of construction.
Utility model content
The technical problems to be solved in the utility model is: overcome the problems referred to above, provide in a kind of being applicable to, low water head hydraulic tunnel construction the permanent shutoff in hole or the main hole of a hydraulic tunnel temporary blocking, and plugging construction workload is little, hole plugging structure is propped up in the construction that plugging effect is good.
To achieve these goals, the technical solution adopted in the utility model is such: hole plugging structure is propped up in construction of the present utility model, comprise a construction hole, a construction top, hole and bottom are all connected with a hole baffle plate, two hole baffle plates connect by reinforcement bar support dagger, and reinforcement bar support dagger arranges through two hole baffle plates, between two hole baffle plates, be provided with access path, access path middle part offers access door, access door is connected with arch occluding body through access path middle part, arch occluding body side is upstream face, the upper and lower two end supports of arch occluding body is on a hole baffle plate of both sides, arch occluding body one side is connected with block section, vertical section, block section is block section broad in the middle small in ends, in block section, be provided with diversion tunnel, between arch occluding body and diversion tunnel, form and press tunnel, block section arranges near reinforcement bar support dagger.
Further, as a kind of concrete form of structure, arch occluding body described in the utility model is Eccentric Circular Ring one section.
Further, as a kind of concrete form of structure, the circular arc Plane Angle of arch occluding body described in the utility model is between 100 to 120 degree.
Further, as a kind of concrete form of structure, between arch occluding body upstream face described in the utility model and access door and block section, be reserved with and fill seam.
Further, as a kind of concrete form of structure, in filling seam described in the utility model, be provided with packing material.
Compared with prior art, the utility model has the advantage of: during a utility model construction hole plugging structure is applicable to, the construction of low water head hydraulic tunnel the permanent shutoff in hole or the main hole of a hydraulic tunnel temporary blocking, and plugging construction workload is little, plugging effect is good, and can effectively reduce the risk that water pressure is destroyed.
Accompanying drawing explanation
