During frame 4, positioner 43 can prevent steel wire rope 31 from moving up and down and causing 42 deflection of foreboard.Require in addition that each hoist engine 3 is received
Rope reel 33 in same level, ensures that each layer soil sample 8 being capable of horizontal displacement with each positioner 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 horizontal seam 81 for digging out on dykes and dams 82 both sides of longitudinal seam 82 and longitudinal seam, and vegetation on dykes and dams is carried out
Cleaning, reserves a regular section soil sample in a rectangular trapezoid 8, is laterally installing apron plate 5 on 81 walls of seam；Such as：Soil
8 bottom surface of 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, install section filming apparatus 7 on 81 walls of horizontal seam wherein, utilizes camera 76 to record soil sample 8
Not by the cross sectional images before horizontal drawing；By the image transmission that camera 76 records to computer, computer is by it entirely into complete 8 side of soil sample
Face picture；
3rd step, according to the silhouette of soil sample 8 determine the height of soil sample peripheral frame 4, and each group soil sample peripheral frame 4 is being installed to soil sample
On 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 431 3
In angular passage 432, subsequent each 3 rope closing of hoist engine, by 31 pretension of steel wire rope；
4th step, by displacement measurement device 6 be installed to another laterally seam 81 walls, each 62 gauge outfit of dial gauge is pressed in respectively
In block push plate 44, the displacement of push plate 44 is just 4 displacement of soil sample peripheral frame；
5th step, pulled each 4 displacement of soil sample peripheral frame of synchronization pulling by hoist engine 3, and records the displacement of each layer soil sample and horizontal drawing
Value；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 divided by position
Shifting amount, then by the horizontal pull-up values of each layer compared with the horizontal pull-up values of standard, if horizontal pull-up values are more than the horizontal pull-up values of standard then without to dike
Dam is reinforced；
6th step, remove soil sample peripheral frame 4, and 8 silhouette of soil sample is recorded by camera 76.
By the horizontal drawing of synchronization of each layer soil sample 8, the horizontal pull-up values of each layer soil sample 8 when recording horizontal drawing step by step and synchronous horizontal drawing, according to
Each horizontal pull-up values of layer are to judge that can each layer of dykes and dams withstand current 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, with not carried out before horizontal drawing pair
Than the sliding situation of each 8 layers of soil sample being observed, to determine whether to have carried out effective horizontal drawing to each layer soil sample 8.
Front and rear picture archive can also be pulled on, and is compared and analyzed with conventional cross sectional images, draws 8 section of soil sample
Situation of change and variation tendency.
Before the 3rd step is carried out, soil sample 8 can be prepared into semi-saturation soil sample 8, its operating method is to consolidate earth-retaining net 9
It is fixed to soil sample 8 towards the wall 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
Closed, pour water in most backward 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 soaked 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 obtained, if certain layer of 8 horizontal pull-up values of soil sample are less than the horizontal pull-up values of standard, then should
Protected when to dykes and dams add.
, it is necessary to be broken soil sample 8 by hoist engine 3 before the 6th step is carried out, 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
During 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 drawn by curve, it is instantaneous horizontal
Value when pull-up values are declined suddenly for each 8 pulling force of layer soil sample by peak, by instantaneous horizontal pull-up values compared with standard value, judges dike
Whether dam needs reinforcement.
