Description

technical field

Background technique

In the civil construction of power substation projects, when encountering earthwork such as slope protection and excavation, due to the limitation of measuring tools, disputes often arise between Party A (supervisor) and the construction team due to the amount of slope release. For example, on both sides of the substation access road, the construction drawings require 1:1 slope protection (that is, 45° slope protection). Due to the limitation of measurement tools, construction personnel rely on visual judgment during construction, and there is a large compilation error. During the construction, the slope protection and other excavations were not enough. During the acceptance inspection, Party A found that large machinery entered the site for the second time to repair the slope, which would cause a lot of lost time and cost, and was time-consuming and laborious. If the excavation is too large, the amount of earthwork will exceed the engineering quantity of the construction drawings, and the land acquisition area may increase, and the construction cost will exceed the budget.

(2) Later, the slope protection was measured with an isosceles triangle ruler nailed on the spot. The wooden triangular ruler has poor strength and stability and is inconvenient to carry. It can only measure the working surface at an angle of 45°, and the measurement accuracy is poor.
