Description
Technical field
The present invention relates to water conservancy and hydropower facility technology fields more particularly to a kind of flowing hole to form device and Construction of Silo side
Method.
Background technique
In hydraulic and hydroelectric engineering, frequently involving concrete structure needs substage construction and needs before second stage concrete pours full
The case where sufficient overcurrent requires.The case where being combined such as currently a popular shaft spillway with diversion tunnel, as shown in Figure 1, with perpendicular
The diversion tunnel 500 that well 100 is connected to divides vertical shaft 100 for upper semisection and lower semisection, and construction time diversion tunnel 500 is generally using permanent perpendicular
Subsequent 200 overcurrent of tunnel of well 100.For the overcurrent requirement for meeting construction time diversion tunnel, traditional method is usually in vertical shaft 100 1
After the completion of phase lining concrete layer pours, flowing hole 300 is opened on a phase lining concrete layer, coagulation is used after the completion of overcurrent
Native plug 400 blocks, due to concrete plug water penetration is strong and plug 400 and flowing hole 300 there are structure gaps, to avoid this
300 leak of flowing hole meets 100 later period of vertical shaft service requirement, and water sealing structure need to be arranged at flowing hole 300.It is more actual
Way is fixed water sealing structure in flowing hole structural joint position, then pour second stage concrete lining cutting layer before the second phase pours.I.e.
The waterstop sealing of flowing hole 300 can be achieved.
However, traditional method need to slot in fist stage concrete, fluting need to cut off the surface layer reinforcing bar of fist stage concrete, not only
Construction is inconvenient, causes construction efficiency low；And fluting can damage the overall structure of vertical shaft 100, be unfavorable for the long-term fortune of vertical shaft 100
Row.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, provide a kind of simplified Construction of Silo process,
Construction of Silo efficiency is improved, and reduces the damage to fist stage concrete, while meeting the overcurrent before second stage concrete pours and seam
The flowing hole that gap waterstop sealing requires forms device.
In order to solve the above technical problems, the invention adopts the following technical scheme:
A kind of flowing hole formation device, the flowing hole form the intersection that device is set to vertical shaft and tunnel；The flowing hole shape
It include baffle ring and multiple embedded water stop structures at device；
The space that the baffle ring inner wall surrounds forms flowing hole, and the outer wall of the baffle ring is for one phase of vertical shaft with flowing hole periphery
Liner structure connection；
The embedded water stop structure includes housing and sealing piece；The housing is set on the outer wall of baffle ring, the sealing piece

The sealing element in gap between head.
Flowing hole, and embedded water stop piece, one phase of vertical shaft lining are formed before vertical shaft one phase lining cutting pours by the device as a result,
After block pours, diversion tunnel overcurrent can be completed without fluting and check and accept, it is not only small to the damage of fist stage concrete, but also Construction of Silo
Process is simplified, Construction of Silo efficiency is improved.
Sealing piece is bent in housing, it is ensured that is not destroyed when overcurrent；After overcurrent before pouring plug, straight sealing is broken
Piece forms water sealing structure, prevent seam leak.Water sealing structure setting is integrated in a procedure with flowing hole formation, and
It is easy for construction, construction is further simplified, construction efficiency is improved.As a further improvement of the above technical scheme:
The embedded water stop structure be equipped with it is multiple, multiple embedded water stop structures along the baffle ring circumferentially, multiple sealing sections
The sealing element for sealing gap between flowing hole and plug is enclosed after recovery original shape.
To dismantle convenient for baffle ring, the two sides of the housing are arranged with connecting plate, and the outer wall of the connecting plate and baffle ring is solid
It is fixed.Connecting plate is preferably connect with baffle ring spot welding.
To guarantee that the present apparatus is connected firmly with phase lining cutting, high-velocity flow is avoided when overcurrent to destroy by rush of water the present apparatus, the connection
The more dowels connecting with the bar construction of vertical shaft one phase lining cutting are fixed on plate.
There is negative pressure to avoid overcurrent or pouring in the too fast housing cavity of flow velocity, causes baffle ring deformation even to destroy, institute
It states and is equipped with filler, the preferred coarse sand of the filler in housing.On the one hand can be to avoid the above problem, it on the other hand can also be right
Steel plate forms support, improves the reliability of the present apparatus.
It is preferred that the baffle ring is enclosed by muti-piece baffle.
The inventive concept total as one forms device progress vertical shaft using above-mentioned flowing hole the present invention also provides a kind of
The method of construction, comprising the following steps:
S1: the outer wall of the baffle ring is connect with the bar construction of the vertical shaft one phase lining cutting of flowing hole periphery, in a phase, lining cutting is poured
Casting concrete in space is built, a phase lining concrete layer is formed；
S2: it completes diversion tunnel overcurrent and checks and accepts；
S3: baffle ring is removed, and the lower part of sealing piece is restored to the original state, pours the plug for blocking the flowing hole, is made described
Plug and sealing element are connected.
As a further improvement of the above technical scheme:
Its spy is, further comprising the steps of:
S4: pouring the second stage of lining concrete layer, completes Construction of Silo.
Compared with the prior art, the advantages of the present invention are as follows:
1, the invention avoids slotting on fist stage concrete, easy for construction, water-stagnating effect is reliable, not only reduces mixed to a phase
The damage of soil is coagulated, while meeting the requirement of the overcurrent before second stage concrete pours.
2, the present invention, which is suitable for concrete structure, needs substage construction, and by stages during have the case where overcurrent requirement, have wide
General engineering application value.
