Problems solved by technology

[0002] Engineering survey refers to the general term for all surveying and mapping work in engineering construction, including various surveying work carried out in the stages of engineering construction survey, design, construction and management; engineering surveying is divided into engineering control surveying in the survey and design stage according to its work sequence and nature And topographic survey, construction survey and equipment installation survey in the construction stage, completion survey in the completion and management stage, etc., the survey requires many instruments, and one of the more important measuring instruments is the spirit level, which is an instrument used in all engineering foundations; now When some level instruments are used for actual measurement, because the ground is not flat enough, it is easy to cause the position of the level instrument to be offset, which reduces the measurement accuracy and is not conducive to subsequent construction; therefore, it is necessary to improve the existing technology

Embodiment 1

[0020] see Figure 1-4 , a level used for construction engineering measurement, comprising a base 1, the upper end surface of the base 1 is fixedly connected with a mounting frame 5, a reinforcing rib is fixedly connected between the mounting frame 5 and the base 1, and the mounting frame 5 is movable The base plate 7 is installed, and the upper part of the side of the base plate 7 facing away from the mounting frame 5 is fixedly connected with the mounting base 11, and the lower end of the mounting base 11 is fixedly connected with the base plate 7. , the cross-section of the frame 13 is concave, and the frame 13 is rotated through the assembly shaft 23 to be equipped with a base plate 16, and a level 17 is installed on the base plate 16; one side of the base plate 16 is fixedly connected with an assembly rod 18, and the assembly rod 18 is connected via The wire rope 21 is connected with a positioning block 19; one side of the frame 13 and the base plate 16 is provided with a...

Embodiment 2

[0029] In order to improve the working effect of the shock absorbing spring 20 and avoid the jamming of the assembly seat 4 and the base 1, this embodiment is improved on the basis of the embodiment 1, and the improvements are: the two sides of the assembly seat 4 The rollers fitted are attached to the inner wall of the base 1 so that the sliding of the assembly seat 4 is smoother and the damping effect of the damping spring 20 is improved.

Abstract

The invention discloses a gradienter for constructional engineering measurement. The gradienter comprises a base, wherein a mounting frame is fixedly connected to the upper end face of the base, a base plate is mounted on the mounting frame, a mounting base is fixedly connected to the upper portion of the side, deviating from the mounting frame, of the base plate, a rack is assembled at the upperend of the base plate through a rotating shaft, and a gradienter body is mounted on the bottom plate. According to the gradienter for constructional engineering measurement, a positioning block is arranged to be matched with scale marks, so that a user can conveniently check whether the placement position of the gradienter deviates or not in time; moreover, the gradienter can deflect by rotating the worm until the gradienter and the center line of the scale line are positioned on the same vertical line, so that the measurement precision is ensured; the base plate can be driven to lift by rotating a hand wheel, so that the placement position of the gradienter is changed; in addition, a damping spring is arranged between an assembling base and the base, so that the gradienter is more stablewhen moving on an uneven road surface.
