before installing and supporting hydraulic equipment, the depth of an earthen site excavation area and the height of an excavation port are sequentially measured, corresponding adjustment operation is carried out according to the height of the excavation port, a first threaded connecting cylinder 502 is arranged in a twisting longitudinal expansion degree adjusting assembly 5 to rotate, under the combined action of torsion force and threaded engagement force, a first threaded connecting shaft 503 can do linear motion in the first threaded connecting cylinder 502, a longitudinal movable seat 403 is pulled or pushed to do corresponding expansion motion in a longitudinal expansion port 402 through the linear motion of the first threaded connecting shaft 503, corresponding adjustment operation is carried out according to the depth of the excavation port, a first threaded connecting cylinder 502 is arranged in a twisting transverse expansion degree adjusting assembly 2 to rotate, further, a transverse movable seat 103 can be pulled or pushed to do corresponding expansion motion in a transverse expansion port 102, an arch angle at the top of the excavation area is corresponded, a second threaded connecting cylinder 702 is twisted to rotate, under the combined effect of the torque force and the thread engagement force, the second threaded connecting shaft 703 can make linear motion in the second threaded connecting cylinder 702, a pulling force or a pushing force is applied to the first inclined supporting sleeve plate 603 through the linear motion of the second threaded connecting shaft 703, and when the first inclined supporting sleeve plate 603 is subjected to the pulling force or the pushing force, on one hand, the end, far away from each other, of the first inclined supporting beam 602 and the second inclined supporting beam 604 can respectively rotate by taking the transverse adapter 601 and the longitudinal adapter 605 as rotating centers, the end, close to the first inclined supporting beam 602 and the second inclined supporting beam 604, can make corresponding telescopic motion on the inner side of the first inclined supporting sleeve plate 603, and the hydraulic equipment can be subjected to multi-directional adjustment of the transverse, longitudinal and arch degrees according to the internal environment of the earthen site excavation area, so that the fitting degree of the hydraulic equipment and the earthen site excavation area is higher, thereby being beneficial to improving the supporting effect of the supporting hydraulic equipment on the excavation and erosion area of the earthen site;
after basic operation and support of supporting hydraulic equipment on an earthen site excavation and erosion area are completed, whether a concave surface area exists at the top of the earthen site excavation and erosion area is checked, if yes, hydraulic oil is filled into a corresponding first hydraulic device 903, a second hydraulic device 907 or a third hydraulic device 909, the oil pressure in a hydraulic cylinder is gradually increased along with filling of the hydraulic oil, a piston rod does stretching motion in the piston cylinder under the pushing of the hydraulic oil pressure, and then corresponding areas of a second inclined supporting sleeve plate 901, a third inclined supporting beam 905 or a third inclined supporting beam 905 are pushed to deform until the second inclined supporting sleeve plate 901, the third inclined supporting beam 905 or the third inclined supporting beam is attached to the top of the concave surface area, so that the attachment degree of the supporting hydraulic equipment and the earthen site excavation and erosion area is further improved;
in the process of supporting the earthen site excavation and erosion area by the supporting hydraulic equipment, if a collapse accident occurs, the pressure applied to the second inclined supporting sleeve plate 901, the third inclined supporting beam 905 or the third inclined supporting beam 905 is increased, the corresponding area of the second inclined supporting sleeve plate 901, the third inclined supporting beam 905 or the third inclined supporting beam 905 is deformed under the action of extrusion force, the pressure in the corresponding first hydraulic device 903 or the third hydraulic device 909 is increased when the second inclined supporting sleeve plate 901, the third inclined supporting beam 905 or the third inclined supporting beam 905 is deformed, the hydraulic oil in the first hydraulic device 903 or the third hydraulic device 909 is increased after the pressure in the hydraulic device is increased enters the corresponding compensation port through the hydraulic oil outlet pipe, and the compensation plate 902 is pushed by the hydraulic oil pressure of the hydraulic oil to extend outwards so as to increase the supporting area of the earthen site excavation and erosion area, thereby preventing the collapse of the earthen site excavation and erosion area from further spreading to a certain extent;
when the large area of earthen site excavation area collapses, the pressure that supports hydraulic equipment and receive can promote by a wide margin, under the effect of holding down pressure, slide seat 1001 and slide in the surface of support sleeve 1002 downwards, support the bottom of sliding seat 1001 at earthen site excavation area, again assist with anti-skidding gyro wheel 1005, because whole support hydraulic equipment is similar triangle-shaped structure, support hydraulic equipment and can receive side thrust, under the effect of side thrust under the support hydraulic equipment the inside of earthen site excavation area is followed the degree of collapsing and is removed to the completion, thereby can slow down the speed of collapsing in earthen site excavation area to a certain extent, make support hydraulic equipment have the automatic movement function, can avoid the earthen site excavation area to collapse and take place the breakage under the top that supports hydraulic equipment when the large area.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
