Problems solved by technology

[0004] This measurement method has high requirements on the flatness of the slope surface. Once the slope surface is uneven, it will cause a large error in the measurement results. However, it is difficult to achieve the ideal flatness of the slope in actual construction. Therefore, the above-mentioned measurement methods have great limitations

Embodiment Construction

[0034] refer to Figure 1 to Figure 5 Further explanations are given on the road gradient scale used in engineering supervision.

[0035] A kind of engineering supervision is used road slope gauge, asfigure 1 As shown, it includes a main ruler 1, a slope indicator 2 arranged on the main ruler 1, an extension ruler 3 that is slidably arranged at both ends of the main ruler 1, and a leg 4 fixedly arranged at one end of the two extension rulers 3, respectively. The flattening component 5 , the pressing component 6 and the flatness measuring component 7 are all slid sequentially on the main scale 1 .

[0036] Among them, such as figure 1 and image 3 As shown, the gradient indicator 2 includes a dial 21 fixedly arranged on the main ruler 1 and a pointer 22 which is rotatably arranged on the axis of the dial 21 at one end; , make the level bubble 23 in a horizontal state, at this time, the reading of the pointer 22 on the dial 21 is used to calculate the slope of the side slope....

Abstract

The invention discloses a road grade scale for construction supervision. The road grade scale comprises a grade indicator arranged on a main scale, support leg arranged on two ends of the main scale,a mounting frame slidably arranged on the main scale, a flattening assembly and a pressing roller arrange on the mounting frame, a sliding frame slidably arranged on the main scale, a detection rod slidably arranged on and passing through one end wall of the sliding frame, a baffle plate fixedly arranged on one end of the detection rod, a fixed frame fixedly arranged on the other end of the detection rod, a compression spring sleeving the detection rod and having two ends respectively connected with the sliding frame and a fixed member, and a roller rotatably arranged on the sliding frame, wherein the baffle plate contacts and is connected with the end surface of the sliding frame under the action of the returning force of the compression spring; the mounting frame is provided with an inductive component used for inducing the position of the baffle plate; the pressing roller is rotatably arranged on and connected with the mounting frame; the mounting frame and the sliding frame are connected by a connecting rod; and the pressing roller is arranged between the flattening assembly and the sliding frame. The road grade scale realizes the measurement of the grade of a roadbed slope andimproves the measurement accuracy of the grade of the roadbed slope.

Description

technical field [0001] The invention relates to a detection device for engineering supervision, more specifically, it relates to a road gradient gauge for engineering supervision. Background technique [0002] The side slope slope of the highway subgrade depends on the geological and hydrological conditions and the height of the excavation and filling of the subgrade. Once the design slope of the side slope is determined, if it exceeds the specified value during construction, it will cause an increase in the occupied area and the economic cost of the cross section. ; If it does not reach the specified value, it will directly affect the stability of the subgrade and bury hidden dangers in quality. Therefore, accurate measurement of the slope slope of the subgrade during construction can not only make the slope quickly form, save construction time, but also make the subgrade The stability is effectively guaranteed. [0003] When measuring the slope of the subgrade slope at pr...
