Device used for forming holes in surface of side slope model

Abstract

The invention provides a device used for forming holes in the surface of a side slope model. The device comprises an upper horizontal rail, a lower horizontal rail and a connecting rod connecting theupper horizontal rail to the lower horizontal rail, wherein Z-direction brackets capable of moving in a length direction of the upper horizontal rail and the lower horizontal rail are arranged on theupper horizontal rail and the lower horizontal rail; a balance rail capable of being regulated to the horizontal direction is arranged between the Z-direction brackets; and an soil taking drill whichmoves in the length direction and is vertically downward is arranged on the balance rail. Through the upper horizontal rail with scales, the lower horizontal rail with scales and the Z-direction brackets, the device can regulate the position of the soil taking drill and soil drilling depth according to practical needs; the connecting rod is formed by hinging a plurality of telescopic joints, and length of the telescopic joints can be regulated to adapt to side slope models of various gradients; the soil taking drill is arranged on the balance rail which can be arranged in the horizontal direction, so that the drilling direction can be ensured to be vertical, and drilling position and drilling depth can be guaranteed to be precise. The device is simple in structure, is convenient in operation, saves time, and improves working efficiency.

Description

technical field [0001] The invention belongs to the technical field of geotechnical test auxiliary equipment, in particular to a device for forming holes on the surface of a slope model. Background technique [0002] In the geotechnical centrifugal model test, the wharf model as a whole is generally located on the slope of the bank slope, and the wharf model piles are vertically inserted into the slope. The traditional method is that before the test starts, it is necessary to convert according to the pile spacing and slope slope of the pile foundation plan of the wharf, draw the points of each pile on the slope, and use iron rods to insert vertically into the soil to form holes. Then the piles of the entire wharf model are aligned with the holes and inserted into the bank slope model, but the above method cannot guarantee that the spacing of the holes is accurate, and at the same time it cannot guarantee that the holes formed are vertical, resulting in the initial stress of ...

The traditional method is that before the test starts, it is necessary to convert according to the pile spacing and slope slope of the pile foundation plan of the wharf, draw the points of each pile on the slope, and use iron rods to insert vertically into the soil to form holes. Then the piles of the entire wharf model are aligned with the holes and inserted into the bank slope model, but the above method cannot guarantee that the spacing of the holes is accurate, and at the same time it cannot be guaranteed that the holes formed are vertical, resulting in the initial stress of the model piles too large to be realistic
