Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.At this it should be noted that saying for these embodiments
Bright being adapted to assist in understands this utility model, but is not intended that restriction of the present utility model.
As it is shown in figure 1, this utility model includes being close to the elevation water inlet 1 arranged continuously outside low elevation water inlet 2, institute
The column foot 100 stating elevation water inlet 1 includes being positioned at the local excavation space 101 of elevation water inlet column foot side slope 110, mixes
Solidifying earthen backfill body 102 and the shallow-layer vertical pore-creating consolidation grouting portion 103 being positioned at column foot 100 upper strata, described concrete backfill body 102
It is cast in described local excavation space 101, also includes the deep horizontal pore-creating consolidation grouting portion 104 being positioned at column foot 100 lower floor,
Described local excavation space 101 extends to the column foot end face of low elevation water inlet 2 from column foot 100 end face of elevation water inlet 1,
The concrete that described deep horizontal pore-creating consolidation grouting portion 104 uses the pre-buried skirt 105 being more than pore-creating aperture to lead to side slope returns
Fill out body 102 leading edge.When excavating local excavation space 101, by elevation water inlet column foot side slope 110 surface by being pre-designed
Gradient excavation and fall clearly surface and loosen sillar clearly at excavation line 4.Elevation water inlet 1 is close to outside low elevation water inlet 2
Arrange continuously, discrepancy in elevation excavation space arranging tower bases can be made full use of, be relatively separately provided water inlet and save earthwork, and also can
The self-resistance making full use of low elevation water inlet tower body concrete increases the lateral stability degree of safety of column foot side slope.Traditional tower
Base consolidation grouting method is along the vertically arranged grout hole of column foot, carries out consolidation grouting from vertical grout hole, but this grouting method
Upper column body concrete just can be poured after needing to wait whole being in the milk.And this utility model is provided with deep water in column foot lower floor
Flat pore-creating consolidation grouting portion 104, at the horizontally disposed grout hole in this position, and connects at the aperture in plasm pouring in plane hole
The pre-buried skirt 105 that diameter is more slightly larger than aperture, plasm pouring in plane hole, pre-buried skirt 105 extends to the concrete backfill body 102 of side slope
Leading edge, so, just can cause in plasm pouring in plane hole by pre-buried skirt 105 by serosity when being in the milk water inlet tower body,
Thus reach the purpose that tower body and deep horizontal pore-creating consolidation grouting portion 104 are in the milk simultaneously.Deep layer scope uses horizontal pore-creating solid
Knot grouting, it is to avoid being difficult to of column foot deep layer vertical pore-creating consolidation grouting, greatly reduces difficulty of construction, and uses pre-buried skirt
Leading to the grouting of side slope fill concrete leading edge skirt, the concreting of two tower bodies also can carry out simultaneously, not interfere with two tower bodies
The progress of concreting, is substantially shorter its construction period.Bank tower intake combined layout in many holes disclosed in this utility model
Column foot foundation processes structure and not only fully ensures that the stable safety of column foot, and reduces difficulty of construction, shortens the construction period, reduces
Construction investment.
Specifically, in order to improve edge slope structure and the stability of column foot, elevation water inlet between elevation column foot and low elevation column foot
1 and low elevation water inlet 2 tower body between set structural joint 3, described structural joint 3 extends to the unfavorable structural plane of column foot side slope from tower top
Locate on 111 exposure elevations.The unfavorable structural plane of column foot side slope 111, tower is there is unavoidably in elevation water inlet column foot side slope 110
Base side slope may be slided along column foot side slope unfavorable structural plane 111 and be cut, if at elevation water inlet 1 and low elevation water inlet 2
The structural joint 3 running through whole tower body is set between tower body, the side slope between elevation water inlet 1 and low elevation water inlet 2 will be reduced
Structural stability.This utility model use structural joint 3 from tower top extend to column foot side slope unfavorable structural plane 111 exposure elevation it
The seam end altitude traverse 31 at upper place, i.e. structural joint 31 is higher than the exposure elevation of the unfavorable structural plane of column foot side slope 111, at tower between two towers
Not parting below base side slope unfavorable structural plane 111 exposure elevation, the self-resistance that can make full use of low elevation tower body concrete increases
Add the lateral stability degree of safety of column foot side slope, stitch 3 in column foot side slope unfavorable structural plane 111 exposure elevation arrangement above, seam
Between set elastic insert, to adapt to elevation bank tower intake 1, low elevation bank tower intake 2 sedimentation and deformation or temperature deformation
Deng.
Specifically, for the geological problems such as the air slaking existed after solving column foot slope excavating, off-load, compressive zone structural plane, this practicality
The novel column foot side slope combined bolting and shotcrete 106 that also includes, described column foot side slope combined bolting and shotcrete 106 includes many anchor poles 1061, described anchor
A part for bar 1061 gos deep into elevation water inlet column foot side slope 110, and another part gos deep in concrete backfill body 102.Column foot
Side slope combined bolting and shotcrete 106 can ensure that the stability of side slope self.Preferably, described anchor pole 1061 gos deep into concrete backfill body
30～40 times of a length of anchor pole 1061 diameter in 102, it is ensured that bonding firm between batholith with concrete backfill body 102
Property.
Embodiment
As it is shown in figure 1, first excavation slope, form local excavation space 101；Then due to exist after column foot slope excavating air slaking,
The geological problems such as off-load, compressive zone structural plane, need to use combined bolting and shotcrete in advance, ensure side slope self including anchor cable 1061 measure such as grade
Stablize, side slope anchor pole 1061 gos deep into a length of 35 times of bolt diameters of concrete backfill body 102, it is ensured that batholith and concrete
The strong bond of backfill body 102；Then the column foot base of fill concrete paramount elevation water inlet 1 in local excavation space 101
Face；Then in the vertical pore-creating of column foot shallow-layer, consolidation grouting is carried out, to improve shallow-layer air slaking, the integrity on off-load batholith basis；
In view of being difficult to of construction period and column foot deep layer vertical pore-creating consolidation grouting, column foot deep layer uses horizontal pore-creating consolidation grouting, and
Use concrete backfill body 102 leading edge leading to side slope slightly larger than the pre-buried skirt 105 in pore-creating aperture, treat that flood discharging tunnel side slope mixes
After solidifying earthen backfill, use two sequence grouting, the grouting of horizontal skirt and elevation water inlet 1, low elevation water inlet 2 in the range of deep layer
Concreting can carry out simultaneously, do not interfere with each other, be greatly shortened its construction period.There is the unfavorable knots such as compressive zone due to column foot
Structure face, column foot side slope may be slided along column foot side slope unfavorable structural plane 111 and be cut, therefore, at cast elevation water inlet 1
During the tower body of tower body and low elevation water inlet 2, not parting below the column foot side slope unfavorable structural plane 111 exposure elevation between two towers,
This structure can make full use of the lateral stability degree of safety of the self-resistance increase column foot side slope of low elevation tower body concrete, at tower
Base side slope unfavorable structural plane 111 exposure elevation arrangement above seam 3, sets elastic insert between seam, tower to adapt to elevation bank
Water inlet 1, low elevation bank tower intake 2 sedimentation and deformation or temperature deformation etc..
