Abstract
The utility model discloses a water conservancy water and electricity structure, especially a concrete shore protection scour protection structure who is applicable to the high -velocity flow flood discharge and erodees the district. The utility model provides a construction convenience is and effective reliable shore protection scour protection structure, including the concrete revetment, still include the toe key -wall, the toe key -wall sets up the toe department at the concrete revetment, the bottom of toe key -wall is provided with one row at least dowel and restraints the stake to restraint the stake hole to the dowel and carry out consolidation grouting. Toe key -wall and above concrete all are located on waterly, and construction convenience can fully guarantee the construction quality of concrete to can bear flood discharge the erodeing the shore protection of surging. It restraints the stake to set up the dowel that is not less than flood discharge scouring depth below the key -wall to utilize a dowel bundle stake hole to carry out consolidation grouting, strengthen dashing the rock mass strength and the rock mass wholeness of cheating the within range, improve it and resist towards the ability, formed one firm resisting towards the line of defence under water.
Description
Technical field
This utility model relates to a kind of water conservancy and hydropower structure, especially a kind of concrete revetment anti-washing structure suitable in high-velocity flow spillway section district.
Background technology
During high-velocity flow flood discharge, owing to its flood discharge energy is huge, downstream river course spillway section region shore slope is very easily destroyed by scour, it is therefore necessary to bank slope carries out reliable shore protection design for erosion protection.The anti-scouring wall under water adopted effectively reliable more at present, but difficulty of construction is bigger；Though anti-key-wall easy construction of washing in a pan waterborne, but not fully reach the anti-purpose washed in a pan, it is possible to damaged or destroyed by flood after flood and often repair.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of easy construction and effectively reliable shore protection anti-washing structure.
This utility model solves the shore protection anti-washing structure that its technical problem adopts, including concrete revetment, also including toe key-wall, described toe key-wall is arranged on the toe place of concrete revetment, the bottom of described toe key-wall is provided with at least one row's dowel bundle stake, and dowel bundle stake holes is carried out consolidation grouting.
Further, described toe key-wall is inverted trapezoidal shape.
Further, the degree of depth of described toe key-wall is 2.0～4.0m, minimum bottom width 1.0～3.0m.
Further, described toe key-wall is chamfer trapezoidal shape, its hypotenuse concrete revetment dorsad.
Further, the degree of depth 9.0～36.0m, the spacing 1.0～3.0m of described dowel bundle stake, gos deep into toe key-wall 0.8～3.0m.
Further, described dowel bundle stake is provided with 1～2 row.
The beneficial effects of the utility model are: toe key-wall and above concrete are respectively positioned on waterborne, and easy construction can fully ensure that concrete construction quality, surge washing away shore protection it is thus possible to bear flood discharge.The key-wall dowel bundle stake being not less than the spillway section degree of depth arranged below, and utilize dowel bundle stake holes to carry out consolidation grouting, strengthens rock mass strength and the rock mass globality of rushing within the scope of hole, improves its impact resistance, defines together firmly anti-impact defence line under water.Comprehensive above underwater protection measure waterborne, it is ensured that shore protection erosion control is effectively reliable.Suitable in the erosion control shore protection on high-velocity flow spillway section district batholith.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Parts, position and numbering in figure: concrete revetment 1, toe key-wall 2, dowel bundle stake 3, dowel bundle stake holes 4.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As it is shown in figure 1, this utility model is by concrete revetment 1, toe key-wall 2, dowel bundle stake 3 forms.
Concrete revetment 1 thickness 0.5～3.0m, it is ensured that enough erosion control rigidity.Toe arranges toe key-wall 2, and it is inverted trapezoidal, the degree of depth 2.0～4.0m, minimum bottom width 1.0～3.0m, conveniently excavates molding, and ensure that construction space and erosion control rigidity.Toe key-wall 2 and above concrete are respectively positioned on waterborne, and easy construction can fully ensure that concrete construction quality, surge washing away concrete revetment 1 it is thus possible to bear flood discharge.The toe key-wall 2 dowel bundle stake 3 being not less than the spillway section degree of depth arranged below, dowel bundle stake 3 degree of depth 9.0～36.0m, dowel bundle can be become by 2～3 tendons, its length can be formed by many bar connecting, spacing 1.0～3.0m, go deep into toe key-wall 2 concrete 0.8～3.0m, dowel bundle stake 3 can be made effectively basement rock and concrete revetment 1 to be linked to be entirety.When building toe key-wall 2 ground floor concrete, reserved dowel bundle stake holes 4, and utilize this hole as consolidation grouting hole, after toe key-wall 2 ground floor concreting completes, implementing to cover heavily segmentation consolidation grouting, consolidation grouting is put into the closely knit sealing of hole of dowel bundle slip casting and is continued Superstructure Construction after having inspected.Dowel bundle stake and consolidation grouting strengthen rock mass strength and the rock mass globality of rushing within the scope of hole, improve its impact resistance, define together firmly anti-impact defence line under water.
This utility model simple in construction, easy construction, investment cost is economized, and shore protection erosion control is effectively reliable.Suitable in the erosion control shore protection on high-velocity flow spillway section district batholith.
Embodiment
Some hydropower station water levels of upstream and downstream drop is big, and maximum drop reaches 240m；Flood discharge flow is big, design/check operating mode flow 3229/3320m3/s；Flood discharge power is big, and flood discharge power reaches 7750MW, and energy is concentrated, but downstream river course is narrow, enters pool water surface width only 60～100m, adopts this practicality shore protection anti-washing structure after deliberation.
Through test, this shore protection anti-washing structure is excellent after flood discharge.
