Description
Technical Field
The utility model relates to a prefabricated corridor, especially a prefabricated corridor of roller compacted concrete dam.
Background
The roller compacted concrete dam is the most commonly adopted dam type in China, and has the advantages that thin layers are quickly constructed and rolled through the warehouse, too many gallery formwork erection processes exist, warehouse face storage time can be occupied, interlayer interval time is too long, interlayer combination is affected, particularly in severe cold areas, the roller compacted concrete dam is unfavorable, the advantage of quick construction of the roller compacted concrete dam is difficult to play, the planned construction period is often delayed, loss is caused to construction units, adverse effects are brought to the whole construction organization plan, and difficulty is brought to the performance of benefits of a junction in advance.
Therefore, how to simplify the construction procedure and the gallery design and shorten the warehouse preparation time in the gallery construction process, the advantage of the rapid construction of the roller compacted concrete dam is brought into play, and the problem to be solved is needed urgently.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a prefabricated corridor for roller compacted concrete dam is provided, need not to erect the template, need not the maintenance, and the installation of on-the-spot handling saves storehouse face space, and the later stage need not to dismantle, saves construction cost, can full play roller compacted concrete dam advantage of being under construction fast.
In order to solve the above problem, the utility model discloses the technical scheme who adopts is: the utility model provides a prefabricated corridor for roller compacted concrete dam, a serial communication port, including the prefabricated corridor of first half side that has the bellmouth and the prefabricated corridor of second half side that has the socket, the bellmouth of the prefabricated corridor of first half side and the socket equipment of the prefabricated corridor of second half side form one section complete corridor, the bellmouth of the prefabricated corridor of first half side is located corridor arc top, the bellmouth is provided with the slot, be equipped with the stagnant water sticky tape on the slot groove face, the socket of the prefabricated corridor of second half side is located corridor arc top, be provided with the plug on the socket, front and back end and the bottom contact surface of the prefabricated corridor of first half side and second half side all are equipped with sealed glue.
The structure of the first half side prefabricated gallery and the second half side prefabricated gallery is an arc gallery side wall connected to the middle of the base plate, and the whole prefabricated reinforced concrete structure of the self-stabilizing structure is formed.
The thickness of the first half-side prefabricated gallery is equal to that of the second half-side prefabricated gallery.
The sealant is polysulfide sealant, polyurethane sealant or silicone sealant.
The thickness of the first half side prefabricated gallery and the second half side prefabricated gallery is 30-40 cm, and the length of the first half side prefabricated gallery and the second half side prefabricated gallery is 2.5-3 m.
The utility model has the advantages that: need not to erect the template, need not the maintenance, the installation of on-the-spot handling saves storehouse face space, and the later stage need not to dismantle, saves construction cost, can full play roller compacted concrete dam advantage of being under construction fast.

Fig. 2 is a schematic illustration of the field installation of fig. 1.
Detailed Description
The invention will be described in further detail with reference to the following drawings and embodiments:
as shown in fig. 1, 2, the utility model discloses a prefabricated corridor for roller compacted concrete dam, including the prefabricated corridor of the first half side 2 of having the bellmouth and the prefabricated corridor of the second half side 3 that has the socket, the bellmouth of the prefabricated corridor of the first half side 2 and the socket equipment of the prefabricated corridor of the second half side 3 form one section complete corridor, the bellmouth of the prefabricated corridor of the first half side 2 is located corridor arc top, the bellmouth is provided with slot 4, be equipped with stagnant water sticky tape 5 on slot 4 trough surface, the socket of the prefabricated corridor of the second half side 3 is located corridor arc top, be provided with plug 6 on the socket, end and bottom contact surface all are equipped with sealed glue 7 around the prefabricated corridor of the first half side 2 and the prefabricated corridor of the second half side 3.
Specifically speaking, the structure of the prefabricated corridor of first half side 2 and the prefabricated corridor of second half side 3 is the arc corridor lateral wall and connects at the middle part of bottom plate base 1, wholly prefabricated reinforced concrete structure who forms the self-stabilizing structure. The thickness of the first half-side prefabricated gallery 2 and the second half-side prefabricated gallery 3 is equal. The sealant 7 is a polysulfide sealant, a polyurethane sealant or a silicone sealant.
The thickness of the first half side prefabricated gallery 2 and the second half side prefabricated gallery 3 is 30-40 cm, and the length is 2.5-3 m.
And (3) carrying out lifting and installation on the site, aligning the plug 6 at the arc top of the second half side prefabricated gallery 3 to the slot 4 at the arc top of the first half side prefabricated gallery 2, lowering and clamping, and extruding the water-stopping adhesive tape 5 on the slot 4 to play a water-stopping role. When the gallery connecting section is installed, the sealant 7 at the end of the gallery can play a role in sealing, water-resisting and grout-isolating.
