Curve line type control device

Abstract

The invention relates to a curve line type control device which comprises a base, a first clamping component, a radius control component and a second clamping component, wherein the first clamping component is provided with a first clamping part; the radius control component is provided with a main clamping part; the second clamping component is provided with a second clamping part; the first clamping component, the radius control component and the second clamping component are all mounted on the base; and the radius control component is located between the first clamping component and the second clamping component. A curve section of a road has the advantages of high boundary stone paving quality, smooth transition, high construction efficiency and construction cost reduction.

Description

technical field [0001] The invention relates to the field of road construction equipment, in particular to a curve control device. Background technique [0002] Many curves are often designed in municipal landscape engineering, such as winding garden roads, slow walkways and so on. The construction quality of these projects is the most difficult to grasp, and various radius curves cannot be set out through precise coordinates. [0003] In the current construction, the curve of the road construction is basically controlled by the hanging wire method, and the road construction is carried out according to the arrangement direction of the hanging wire. Specifically, the hanging line method is to carry out line stakeout by hanging a straight line between two points. At the same time, the purpose of curve stakeout is achieved by densifying the control piles in the curve section. [0004] The designer found in the research that the traditional use of the hanging line method to ac...

AI Technical Summary

Problems solved by technology

[0005] 1. Use a straight line to control the curve, the line type cannot transition naturally, and the arc is not smooth;

[0006] 2. When the line type is determined, it takes a lot of manpower and material resources to make repeated adjustments

[0007] 3. During the construction process, the simplicity of the hanging wire method cannot meet the final curve appearance requirements, so after the construction is completed, it still needs to be adjusted many times, which reduces the construction efficiency;

[0008] 4. There are still problems affecting the construction of the curve control piles in actual operation. If the setting is too dense, it will cause mutual interference when placing boundary stones
