Abstract
The invention discloses a kind of construction methods of water conservancy diversion discharge structure comprising step：1）, in the entrance of water conservancy diversion discharge structure and/or outlet port build Temporary Cofferdam, the water retaining structure which constructs as water conservancy diversion discharge structure；2）, Temporary Cofferdam protection in riverbank construct to be formed water conservancy diversion discharge structure import open channel and/or outlet open channel；3）, import open channel and/or outlet open channel in construction form rubber dam；4）, remove Temporary Cofferdam so that using rubber dam become water conservancy diversion discharge structure construction temporary water retaining cofferdam；5）, wait for water conservancy diversion discharge structure all after the completion of construction, release the air or water in rubber dam.The Temporary Cofferdam that the present invention is effectively shortened water conservancy diversion discharge structure removes the time, the air or water in rubber dam can rapidly be released, so that river in water from water conservancy diversion discharge structure overcurrent, can be effectively increased river closure cofferdam dry season construction duration.
Description
Technical field
The present invention relates to hydraulic and hydroelectric engineering technical fields, and in particular to a kind of construction method of water conservancy diversion discharge structure.
Background technology
Shutting off for river usually requires first to build water conservancy diversion discharge structure, and water conservancy diversion discharge structure is one provisional or forever
The engineering construction of long property, it is often very urgent that one of its feature, which is the duration, if cannot complete on schedule, be will result in entire
Effective construction duration in the postponement shut off and the dry season for shortening cofferdam, water conservancy diversion discharge structure are by former streamflow from cofferdam
Upstream is oriented to the flow-guiding channels such as diversion tunnel, the diversion canal in cofferdam downstream.
Under normal conditions, the import open channel of water conservancy diversion discharge structure and outlet open channel in generally require build Temporary Cofferdam work
For the water retaining structure of water conservancy diversion discharge structure construction, wait for that water conservancy diversion discharge structure builds completion, dry season, interim riverbed was cut
The Temporary Cofferdam is removed before stream, and the water in river is introduced into water conservancy diversion discharge structure to the changed course for realizing rivers current, in order to
Carry out river shut off and coffering.However, the prior art, for the engineering in Large River, coffering is larger,
Shut off and cofferdam needs to complete construction within a dry season, the construction period is nervous, and water conservancy diversion discharge structure imports and exports open channel
Interior Temporary Cofferdam structural shape is generally concrete or rock structure type, and projects amount is big, long in time limit, directly affects river
Road shuts off the time started, accounts for the pressure riverway cofferdam construction time in dry season.
Invention content
In order to solve water conservancy diversion discharge structure inlet and outlet open channel inner concrete or rock structure Temporary Cofferdam in the prior art
Projects amount is big, long in time limit, accounts for the problem of pressing the river closure cofferdam construction time in dry season, the present invention provides a kind of water conservancy diversion
The construction method of discharge structure.Specific technical solution and steps are as follows.
1）, in the entrance of water conservancy diversion discharge structure and/or outlet port build Temporary Cofferdam, the Temporary Cofferdam is as water conservancy diversion
The water retaining structure of discharge structure construction；
2）, Temporary Cofferdam protection in riverbank construct to be formed water conservancy diversion discharge structure import open channel and/or outlet open channel；
3）, the import open channel and/or outlet open channel in construction form rubber dam；
4）, remove Temporary Cofferdam so that using rubber dam become water conservancy diversion discharge structure construction temporary water retaining cofferdam；
5）, wait for water conservancy diversion discharge structure all after the completion of construction, release the air or water in rubber dam, and remove rubber dam
Dam bag, water conservancy diversion discharge structure start overcurrent.
In the above-mentioned technical solutions, the height of the rubber dam according to the import of the diversion structure before river closure and/
Or the water blocking water level of outlet determines.
In the above-mentioned technical solutions, the water conservancy diversion discharge structure is diversion tunnel or diversion canal.
Construction method of the present invention relative to existing water conservancy diversion discharge structure, is effectively shortened water conservancy diversion discharge structure
Temporary Cofferdam remove the time, can dry season arrive after, rapidly release rubber dam in air or water so that in river
Water from water conservancy diversion discharge structure overcurrent, can be effectively increased river closure cofferdam dry season construction duration.
Description of the drawings
Fig. 1 is the floor map of the present invention；
Fig. 2 is the sectional view along water conservancy diversion discharge structure axis in Fig. 1.
In figure：The rivers 1-, the riverbanks 2-, 3- water conservancy diversion discharge structure, 4- imports open channel, 5- rubber dams, 6- Temporary Cofferdams.
Specific implementation mode
Present invention is further described in detail below in conjunction with the accompanying drawings.
Referring to Fig. 1-2, the construction method of water conservancy diversion discharge structure mainly includes the following steps that：
1）, water conservancy diversion discharge structure 3 entry position build Temporary Cofferdam 6, the Temporary Cofferdam 6 be used as water conservancy diversion discharge structure
The water retaining structure of construction；
2), the riverbank 2 in the protection of Temporary Cofferdam 6, which is constructed, forms the import open channel 4 of water conservancy diversion discharge structure 3；
3）, in the import open channel 4 construction form rubber dam 5, the height of rubber dam 5 is built according to the water conservancy diversion before river closure
The water blocking water level of import and/or the outlet of object determines；
4）, flood end, remove Temporary Cofferdam 6 so that using rubber dam 5 become water conservancy diversion discharge structure 3 import open channel 4 it is interim
The remainder of water-retaining cofferdam, water conservancy diversion discharge structure 3 is mainly that import open channel and the part exported between open channel continue to construct；
5）, dry season arrive after, water conservancy diversion discharge structure 3 all construction complete, release rubber dam 5 in air or water, and
The dam bag of rubber dam 5 is removed, water conservancy diversion discharge structure 3 starts overcurrent, and river 1 has river closure construction condition and starts to shut off.
Wherein, it is consistent with import to export arrangement and method for construction for water conservancy diversion discharge structure 3；Water conservancy diversion discharge structure 3 can be water conservancy diversion
The flow-guiding channels such as hole or diversion canal.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, it will be understood by those of ordinary skill in the art that：It still may be used
With technical scheme described in the above embodiments is modified or equivalent replacement of some of the technical features；
And these modifications or replacements, various embodiments of the present invention technical solution that it does not separate the essence of the corresponding technical solution spirit and
Range.
