Device and method for measuring gradient of edge slope by fishing rod type gradient ruler from opening line position of edge slope

Abstract

The invention provides a device and method for measuring the gradient of an edge slope by a fishing rod type gradient ruler from an opening line position of the edge slope. The device comprises the fishing rod type gradient ruler and the like. The method comprises the following steps: (1) selecting a measurement position: selecting the measurement position from the upper side where the gradient of the edge slope needs to be measured; (2) retracting the fishing rod type gradient ruler: according to the size of the edge slope needing to be measured, retracting a fishing rod of the fishing rod type gradient ruler to enable a perpendicular line of the end part to reach a position needing to be measured, and hanging a plumb bob at the bottom of the perpendicular line; (3) leveling: adjusting a retractable rod of the fishing rod type gradient ruler to be leveled through horizontal air bubbles on the retractable rod of the fishing rod type gradient ruler; (4) reading: reading a length L for which the fishing rod type gradient ruler stretches out of an opening line of the edge slope and a height H from the perpendicular line of the end part of the fishing rod to the bottom edge of the edge slope; and (5) calculating: according to a gradient calculation formula i=H / L*100%, calculating the edge slope gradient i of the measured position of the fishing rod type gradient ruler. The device and the method are simple in process and convenient to operate; and the fishing rod only needs to be stretched out and leveled, and reading and calculation are carried out to finish the measurement of the gradient of the edge slope.

Description

Technical field: [0001] The invention belongs to the technical field of slope gradient measurement, and in particular relates to a device and a method for measuring the slope gradient from the position of the opening line of the slope with a fishing rod type gradient ruler. Background technique: [0002] In slope excavation or slope backfill construction, the slope slope is generally calculated by measuring the distance and height of the upper and lower points of the slope with a total station. This method needs to place prisms at the upper and lower points of the slope, which is time-consuming and laborious. Importantly, this method can only measure the overall slope of the entire slope, not a specific location on the slope, because the prism may not be placed somewhere in the middle of the slope. Invention content: [0003] The purpose of the present invention is to solve the problem of slope detection at any point on the slope of high excavation or high filling engineer...
