Description
Technical field
The present invention relates to the high retaining wall technical fields of hydraulic and hydroelectric engineering more particularly to one kind can effectively reduce cross dimensions
High retaining wall and construction method.
Background technique
The design of bank aileron is a great and complicated scientific and technical problem in large-scale water conservancy and hydropower multi-purpose project design,
The cost of bank aileron accounts for larger specific gravity in entire engineering project.Common traditional bank aileron design is often empty using big cross section
Case structure or bored concrete pile combine empty case structure.Since wall is higher, water pressure and soil pressure are all quite big after wall, if by normal
The design of empty van formula bank aileron is advised, wall need to have very big weight to resist horizontal force, and in order to avoid wall is to the pressure of foundation soil
Power is not more than the permitted bearing capacity of foundation soil, and empty van structure size certainly will design very big.The section and engineering of the latter's bank aileron
Though amount reduces but bored concrete pile need to expire hall arrangement, pile foundation engineering amount is again larger.Although the hydraulic structure on soil matrix has a large amount of uses
The case history of soil cement, but the overwhelming majority contributes to foundation stabilization or as laying material, to increase the carrying of foundation soil
Power, and the engineering as backfilling material for after bank aileron wall does not have.
The information disclosed in the background technology section is intended only to increase the understanding to general background of the invention, without answering
When being considered as recognizing or imply that the information constitutes the prior art already known to those of ordinary skill in the art in any form.

Step 4 finally backfills soil cement between bank aileron and slopes.
Preferably, in the step 3, the gap 3-5cm is reserved between the bottom of bank aileron and the stake top of bored concrete pile.
3. beneficial effect
Compared with the prior art, the present invention has the advantages that
(1) present invention optimizes the box bank aileron in traditional high-altitude, proposes the novel bank aileron that soil cement is backfilled after a kind of wall,
Soil pressure after wall is greatly reduced, to reduce wall section structure size, preferably resolves setting for soil matrix disembarkation aileron
Problem is counted, bank aileron cost is significantly reduced, economic benefit is obvious；
(2) bored concrete pile that the present invention is arranged under bank aileron hallux, while effectively reducing backfill soil cement and the side of lock chamber is carried
It influences, and side lock chamber and bank aileron can construct simultaneously, save duration and cost, to obtain higher economic results in society.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for the high retaining wall that one kind proposed by the present invention can effectively reduce cross dimensions.
In figure: 1- soil cement, 2- bank aileron, the ground 3-, 4- bored concrete pile, 5- slopes.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
In the description of the present invention, it should be noted that term " center ", "upper", "lower", "left", "right", "vertical",
The orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" be based on the orientation or positional relationship shown in the drawings, merely to
Convenient for description the present invention and simplify description, rather than the device or element of indication or suggestion meaning must have a particular orientation,
It is constructed and operated in a specific orientation, therefore is not considered as limiting the invention.
Referring to Fig.1, a kind of high retaining wall effectively reducing cross dimensions, including ground 3, the side on ground 3 are equipped with
Slopes 5, and 3 inside of ground is equipped with bored concrete pile 4 far from the side of slopes 5, the side of close bored concrete pile 4 is equipped with the bank wing on ground 3
Wall 2, bank aileron 2 are equipped with soil cement 1 close to the side of slopes 5.
In the present invention, for bank aileron 2 using compared with light section, bank aileron 2 presses the measuring pressure coefficient of soil cement 1 using cross dimensions
It determines, bored concrete pile 4 is located under the hallux of bank aileron 2, and the stake diameter of bored concrete pile 4 is not less than 0.6m, and spacing is not less than 5.0m, water after wall
The backfill range of soil 1 is to backfill from the wall bottom of bank aileron 2 to wall top by practical excavation slope 1:1, cement mixing content in soil cement 1
No less than 8%, the height of bank aileron 2 is not less than 20m.
The invention also provides one kind can effectively reduce the construction method of the high retaining wall of cross dimensions, including following step
It is rapid:
Step 1 first excavates the slopes 5 for forming slope of standard according to construction drawing on ground 3；
Step 2 pours several bored concrete piles 4 according still further to side designated position of the construction drawing on ground 3 close to slopes 5；
Step 3 builds bank aileron 2 close to the position of bored concrete pile 4 on ground 3；
Step 4 finally backfills soil cement 1 between bank aileron 2 and slopes 5.
In step 3, the gap 3-5cm is reserved between the bottom of bank aileron 2 and the stake top of bored concrete pile 4, to control bank aileron
Differential settlement amount.
In the present invention, one kind can effectively reduce bank aileron section, and meeting bank aileron and abutment pier can construct simultaneously, reduce engineering
The novel bank aileron of cost, its working principle is that: the cement mixed ratio that soil cement 1 is backfilled after wall is no less than 8%, according to soil cement 1
Laboratory test achievement, the soil cement 1 backfilled after wall is only 0.05~0.1 or so to the coefficient of earth pressure of front wall, is substantially reduced
1 pressure of soil cement after wall, thus reduce 2 section structure size of bank aileron, in the backfill construction of soil cement 1, strict control
Cement mixing content is not less than 8%, selects fresh, agglomeration of not making moist cement, strict control earth material water content, 1 uniform mixing of soil cement
Rear can be used for backfilling, and backfill uses layered rolling method from bottom to top, and every layer is not less than with a thickness of 0.3m or so, compactness
0.94, the soil cement after backfill need to be through detecting, and unconfined compressive strength is not less than 0.9MPa, and internal friction angle is not less than 30 °, cohesion
When power is not less than 80kPa, carry out one layer of backfill, the soil cement 1 itself of backfill can generate certain sedimentation, and soil cement 1 with
There is the presence of frictional force between bank aileron 2, wall certainly will be will drive and settled downwardly together, therefore will lead at 2 hallux of bank aileron
Settling amount it is bigger than front toe place, to solve this uneven subsidence, at bank aileron hallux provided with row's spacing 5m
Bored concrete pile 4, there is no the insertion ground 3 as common filling pile for the bored concrete pile 4, but according to settlement calculation, the stake of bored concrete pile 4
The gap that 3~5cm height is reserved between top and bank aileron bottom plate, controls the differential settlement amount of bank aileron 2, due to bank aileron 2
Using this scheme, it is effectively controlled the hypsokinesis of wall, the bored concrete pile 4 being arranged under 2 hallux of bank aileron effectively reduces simultaneously
Backfill soil cement 1, which carries the side of lock chamber, to be influenced, and side lock chamber and bank aileron 2 can construct simultaneously.
