It is aqueous, there is dry, density CONSENSUS etc.) higher outer, it is also higher to construction requirement, usually it is required for task equipment (abutment wall
Extruder) it constructs, and in order to meet into the smooth deviation requirement of wall, the walking error to machinery is needed strictly to be limited
System.Although existing technology has greatly improved construction effect and construction quality, even if being to be added to accelerator, bedding material
Roller compaction construction still will wait for that side wall concrete intensity reaches requirement and can carry out by a few hours.
Although extrusion side wall in the prior art, which consolidates slope technology, can significantly improve bedding material compaction quality, and easy, timely
Upstream slope protection is provided, the advantages that being conducive to the construction time and pass the flood period, but there is also following disadvantages：One, to concrete mix
Design requirement is higher, and site operation is influenced by environment and personnel, machinery etc., and wall quality is not easy to ensure.Two, extrusion side wall needs
It wants proprietary mechanical (Revetment squeezing press) to construct, and in order to meet into the smooth deviation requirement of wall, needs the walking error to machinery
It is strictly limited, operator quality is required high.Even three, being added to accelerator, the roller compaction construction of bedding material is still
To wait for that side wall concrete intensity reaches requirement and can carry out by a few hours, it reduce construction effects.
Utility model content
The utility model, which provides one kind side wall concrete material property can be effectively ensured, meets design requirement, and material
Consistency of performance is high, construction is simple, is not necessarily to special-purpose machinery, can significantly reduce engineering cost, improves wall quality, is conducive to panel
With the prefabricated abutment wall structure of rock of the compatible deformation of back support structure.
The utility model in order to solve the above problem used by rock prefabricated abutment wall structure, including on the inside of dam body
Bedding material and the wall being affixed with bedding material, the wall are described prefabricated to assemble the splicing construction formed by prefabricated abutment wall
Abutment wall and bedding material are layered setting from low to high.
Further, being additionally provided with location structure between the adjacent prefabricated abutment wall of upper layer and lower layer.
Further, the location structure is the hole slot being arranged on the prefabricated abutment wall of upper layer and lower layer and insertion upper layer and lower layer
Bolt in prefabricated abutment wall hole slot.
Further, the face that the prefabricated abutment wall and bedding material are affixed is inclined-plane.
Further, the end face that adjacent two layers bedding material is affixed with prefabricated abutment wall mutually staggers.
The utility model has the beneficial effects that：Using the prefabricated abutment wall structure of the rock of the application precast plant can profit
With mold pouring construction, it is not necessarily to special-purpose machinery, construction is simple can reduce investment, compared to cast-in-place under complicated construction environment
Rock concrete wall, the application also make rock wall quality be easier to ensure.Using prefabricated construction in field,
Concrete curing condition can be improved, without rapid hardening requirement, not by seasonal effect, late strength of concrete can be utilized at wall, have
Conducive to saving construction investment.And since ambient environmental conditions are stablized, the consistency of performance of prefabricated abutment wall is high.Before panel construction,
The extrusion side wall of the prior art is the constraint for reducing extrusion side wall to panel, need to be cut to abutment wall, and prefabricated abutment wall itself
It is seamed, without cutting, it is more advantageous to the compatible deformation of panel and back support structure.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
In figure label for：Bedding material 1, prefabricated abutment wall 2, hole slot 3, bolt 4, end face 5.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
