Abstract
The invention discloses a construction adit blocking structure which comprises a construction adit, wherein two adit baffle plates are connected to the top and the bottom of the construction adit and connected through reinforcement bar support pillars which penetrate through the two adit baffle plates, a maintenance passageway is arranged between the two adit baffle plates, a maintenance door is arranged in the middle of the maintenance passage, penetrates through the middle of the maintenance passage and is connected with an arch blocking body, an upstream face is arranged on the side surface of the arch blocking body, upper and lower ends of the arch blocking body are supported on the adit baffle plates on two sides, one side of the arch blocking body is connected with a blockage section, the longitudinal section of the blockage section is small in two ends and large in the middle, a diversion tunnel is arranged in the blockage section, and a pressure tunnel is formed between the arch blocking body and the diversion tunnel. The construction adit blocking structure is suitable for permanent blockage of middle and low water head hydraulic tunnel construction adits or temporary blockage of a main tunnel of a hydraulic tunnel, the workload of blockage construction is small, the blocking effect is good, and the hydraulic pressure damage risk can be reduced effectively.
Description
Technical field
The present invention relates to a kind of plugging structure, 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.
Summary of the invention
The technical problem to be solved in the present invention 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 used in the present invention is such: hole plugging structure is propped up in construction of the present invention, 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 of the present invention is Eccentric Circular Ring one section.
Further, as a kind of concrete form of structure, the circular arc Plane Angle of arch occluding body of the present invention is between 100 to 120 degree.
Further, as a kind of concrete form of structure, between arch occluding body upstream face of the present invention and access door and block section, be reserved with and fill seam.
Further, as a kind of concrete form of structure, in filling seam of the present invention, be provided with packing material.
Compared with prior art, the invention has the advantages that: during a present invention 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.
