Description
Technical field
The present invention relates to technical field of wind power generator, particularly relate to a kind of Face Rockfill Dam reversed construction method.
Background technique
Rock is using rockfill as supporting structure, and casting concrete panel in surface is as leakage preventing structure at its upstream
Rock-fill dams, rock is mainly made of rockfill and seepage control system, it may be assumed that panel, toe board, bed course, transition zone, main enrockment
Area, secondary rockfill area composition.In the prior art, the sequence of construction constructed rock usually according to such as Fig. 1, it may be assumed that first
First carry out leading river closure construction and abutment excavation, then carry out dam foundation treatment, then again the excavation of toe board with pour, finally again successively
Fill dam body.It is carried out after general dam embankment should be checked and accepted in the dam foundation, two sides bank processing and corresponding toe board is constructed.Existing panel
Rock-fill dam construction technique, which has the following deficiencies:, is carrying out dam embankment after the completion of dam filling construction this first will wait toe boards to pour,
Filling for toe board cannot many times carry out simultaneously with filling for dam body, and the duration is longer.Secondly excavated in diversion tunnel, toe board slot etc.
Process, many can materials dug out before filling and cannot but go up dam, need rickyard to store and transhipment, increase construction investment.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of Face Rockfill Dam reversed construction methods.
The present invention is achieved by the following technical programs.
The present invention provides a kind of Face Rockfill Dam reversed construction methods, comprising the following steps:
Step 1: construction dam abutment；
Step 2: construction diversion hole and cofferdam are shut off；
Step 3: the construction dam foundation；
Step 4: while secondary rockfill area filling construction, toe board excavation and pouring construction are carried out；
Step 5: main rockfill area filling construction；
Step 6: after panel pouring construction finishes, construction terminates.
Step 1 can construct simultaneously with step 2.
The construction dam foundation described in step 3 includes main rockfill area dam foundation construction and time rockfill area dam foundation construction.
Time rockfill area filling construction described in step 4 refers to by the way of layered rolling filling construction.
The secondary rockfill area up stream slope plane inclination is 1:2.
Main rockfill area filling construction described in step 5 refers to by the way of layered rolling filling construction.
The main rockfill area downstream slope surface gradient is 1:2.
The Face Rockfill Dam reversed construction method is further comprising the steps of:
Step 1: described in step 4 while secondary rockfill area filling construction, reserving Shang Ba highway；
Step 2: described in step 5 while main rockfill area filling construction, using in upper dam highway transportation work progress
Required material.
The beneficial effects of the present invention are: technical solution of the present invention is used, the same of time rockfill area filling construction is being carried out
When, the excavation of toe board slot and the pouring construction of toe board are carried out, construction work can be greatly shortened in two working procedure parallel operations
Phase, during filling construction, the materials such as building stones needed for the construction excavated for diversion tunnel, toe board slot, can with take with
With not needing to build corresponding rickyard, for material temporarily to be stored or transported, save the construction investment of rickyard
Fund, the material that reserved Shang Ba highway is used to use needed for transporting while carrying out secondary rockfill area filling construction, after facilitating
The instant transport of material in continuous working procedure, lays a good foundation to improve filling construction quality.Compared to technology of enjoying, the present invention is big
Amplitude shortens the construction period, improves construction efficiency.
