When frame 4, steel wire rope positioning device 43 can prevent steel wire rope 31 from moving up and down and leading to 42 deflection of foreboard.Require in addition that each elevator
3 rope closing reel 33 of machine in same level, ensures that each layer soil sample 8 being capable of horizontal displacement with each steel wire rope positioning device 43.
It is a kind of that the horizontal pulling method in reservoir dam side slope scene is included the following steps,
The first step, the lateral seam 81 that 82 both sides of longitudinal seam 82 and longitudinal seam are dug out on dykes and dams, and to vegetation on dykes and dams
It is cleared up, reserves a regular section soil sample in a rectangular trapezoid 8, apron plate 5 is installed on laterally 81 wall surfaces of seam；Example
Such as：8 bottom surface of soil sample grow 4 meters, it is 2 meters wide, top surface grow 2 meters, it is 2 meters wide, it is 4 meters high.
Second step, lateral stitches installs section filming apparatus 7 wherein on 81 wall surfaces, and camera 76 is utilized to record soil sample 8
Not by the cross sectional images before horizontal drawing；The image transmission that camera 76 is recorded is to computer, and computer is by it entirely at 8 side of complete soil sample
Face picture；
Third step determines 4 height of soil sample peripheral frame according to the silhouette of soil sample 8, is installed to by each group soil sample peripheral frame 4
In soil sample 8, then the steel wire rope 31 on each hoist engine 3 is nested into outside soil sample peripheral frame 4, and ensures that steel wire rope 31 is located at locating piece
In 431 triangular ducts 432,3 rope closing of subsequent each hoist engine pre-tightens steel wire rope 31；
Displacement measurement device 6 is installed to another laterally 81 wall surface of seam by the 4th step, by 62 gauge outfit pressure of each dial gauge
In each piece of push plate 44, the displacement of push plate 44 is just 4 displacement of soil sample peripheral frame；
5th step, by hoist engine 3 pull it is synchronous pull each 4 displacement of soil sample peripheral frame, and record each layer soil sample displacement and
Horizontal pull-up values；The horizontal pull-up values of soil sample 8 in each soil sample peripheral frame 4 are calculated by displacement and horizontal pull-up values, horizontal pull-up values are removed equal to horizontal pull-up values
With displacement, then the horizontal pull-up values of each layer are compared with the horizontal pull-up values of standard, if horizontal pull-up values are then not necessarily to more than the horizontal pull-up values of standard
Dykes and dams are reinforced；
6th step removes soil sample peripheral frame 4, and 8 silhouette of soil sample is recorded by camera 76.
By the horizontal drawing that synchronizes of each layer soil sample 8, horizontal drawing and the horizontal pull-up values of each layer soil sample 8 when synchronous horizontal drawing step by step are recorded, according to
Each horizontal pull-up values of layer are to judge that can each layer of dykes and dams withstand flow and tidal impulse in flood season.
In addition after the completion of horizontal drawing soil sample 8,8 silhouette of soil sample is recorded by camera 76, and is not carried out before horizontal drawing pair
Than the sliding situation of 8 layers of each soil sample being observed, to determine whether to have carried out effective horizontal drawing to each layer soil sample 8.
Front and back picture archive can also be pulled on, and is compared and analyzed with previous cross sectional images, obtains 8 section of soil sample
Situation of change and variation tendency.
Before carrying out third step, soil sample 8 can be prepared into semi-saturation soil sample 8, operating method is to consolidate earth-retaining net 9
It is fixed to soil sample 8 towards the wall surface of apron plate 5 on, water fender 10 and inserted link 101 be then installed, two blocks of side plates 41 are by 8 both sides of soil sample
It is closed, is finally poured water into permeable cavity 83, permeated from water into soil sample 8 through earth-retaining net 9, soil sample 8 is prepared into
Semi-saturation soil sample 8.
When dykes and dams are impregnated by water for a long time, dykes and dams become semi-saturation soil sample 8, and the horizontal pull-up values of dykes and dams change therewith, it is therefore desirable to
The horizontal pull-up values of each layer soil sample 8 of the dykes and dams in semi-saturation are found out, if certain layer of 8 horizontal pull-up values of soil sample are less than the horizontal pull-up values of standard, are then answered
It is protected when to dykes and dams add.
It before carrying out the 6th step, needs to break soil sample 8 by hoist engine 3, tensiometer 32 records wink when breaking soil sample 8
When horizontal pull-up values.Since soil sample 8 is trapezoidal, soil sample 8 is gradually weak from down to up, therefore is breaking each layer soil using hoist engine 3
When sample 8, soil sample 8 is to be pulled off successively from top to bottom；Tensiometer 32 and dial gauge 62 can be connected with computer, be painted by computer
Relation curve between each layer pulling force and displacement is made, instantaneous horizontal pull-up values of each layer of dykes and dams when bursting are obtained by curve, it is instantaneous horizontal
Pull-up values are value when each 8 pulling force of layer soil sample is declined suddenly by peak, and instantaneous horizontal pull-up values are compared with standard value, judge dike
Whether dam needs reinforcement.
