In triangular duct 432.Each locating piece 431 is fixed in the middle part of 42 end face of foreboard, pulls soil sample peripheral frame 4 in wirerope 31
When, positioning device 43 can prevent wirerope 31 from moving up and down and leading to 42 deflection of foreboard.Require in addition that each 3 rope closing of hoist engine volume
Cylinder 33 in same level, guarantees that each layer soil sample 8 being capable of horizontal displacement with each positioning device 43.
A kind of pair of horizontal pulling method in reservoir dam side slope scene, includes the following steps,
The first step, the lateral seam 81 that 82 two 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 is 4 meters long, 2 meters wide, and top surface is 2 meters long, 2 meters wide, 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 complete 8 side of 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 wirerope 31 on each hoist engine 3 is nested into outside soil sample peripheral frame 4, and ensures that wirerope 31 is located at locating piece
In 431 triangular ducts 432, subsequent each 3 rope closing of hoist engine pre-tightens wirerope 31；
Displacement measurement device 6 is installed to another laterally 81 wall surface of seam by the 4th step, by each 62 gauge outfit pressure of 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 soil sample peripheral frame 4 to be displaced, 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 equal to horizontal pull-up values and remove
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 greater than the horizontal pull-up values of standard and are then not necessarily to
Dykes and dams are reinforced；
6th step removes soil sample peripheral frame 4, records 8 silhouette of soil sample by camera 76.
By the horizontal drawing that synchronizes of each layer soil sample 8, horizontal drawing step by step and the horizontal pull-up values of layer soil sample 8 each when synchronous horizontal drawing are recorded, according to
Each horizontal pull-up values of layer are to judge that can each layer of dykes and dams withstand water 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 two sides of soil sample
It is closed, is finally poured water into permeable cavity 83, permeated from water through earth-retaining net 9 into soil sample 8, 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 horizontal pull-up values of soil sample 8 are less than the horizontal pull-up values of standard, are then answered
It is protected when add to dykes and dams.
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.Due to soil sample 8 be it is trapezoidal, soil sample 8 is gradually weak from bottom to top, therefore is breaking each layer soil using hoist engine 3
When sample 8, soil sample 8 is successively to be pulled off from top to bottom；Tensiometer 32 and dial gauge 62 can be connected with computer, be drawn 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.

Enter to soil sample peripheral frame (4) outside, and ensures that wirerope (31) is located in locating piece (431) triangular duct (432), subsequent each elevator
Machine (3) rope closing pre-tightens wirerope (31)；
Displacement measurement device (6) is installed to another laterally seam (81) wall surface by the 4th step, by each dial gauge (62) gauge outfit
It is pressed on each piece of push plate (44), the displacement of push plate (44) is just soil sample peripheral frame (4) displacement；
5th step pulls each soil sample peripheral frame (4) to be displaced, and records displacement and horizontal pull-up values by hoist engine (3)；
6th step removes soil sample peripheral frame (4), records soil sample (8) silhouette by camera (76).
2. a kind of horizontal drawing test method in reservoir dam side slope scene according to claim 1, it is characterised in that: carrying out the
Before three steps, soil sample (8) can be prepared into semi-saturation soil sample (8), operating method is that earth-retaining net (9) are fixed to soil sample (8)
Towards keeping away on face for apron plate (5), water fender (10) and inserted link (101) be then installed, two pieces of side plates (41) are by soil sample (8) two sides
It is closed, is finally poured water into permeable cavity (83), from water infiltration into soil sample (8) through earth-retaining net (9), by soil sample
(8) semi-saturation soil sample (8) are prepared into.
3. a kind of horizontal drawing test method in reservoir dam side slope scene according to claim 2, it is characterised in that: carrying out the
It before six steps, needs to break soil sample (8) by hoist engine (3), tensiometer (32) record breaks instantaneous horizontal drawing when soil sample (8)
Value.
