[0002] Construction engineering refers to the engineering entity formed by the construction of various buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. During the research and development process, the applicant discovered a Chinese patent that discloses a "Construction Engineering Cost On-site Mapping Device" (Announcement No.: CN222255805U). This patent uses a fixing knob to secure the support rod, enabling it to provide stable support for the vertical pipe. By fixing the first fixing clip at different positions, the outward expansion angle of the vertical pipe can be adjusted, allowing the tripod supporting the mapping device to provide stable support, thus improving the stability of the mapping device's support.

[0003] However, this device requires the use of not only a surveying instrument but also other equipment such as a level, making it difficult to use in conjunction with other equipment. Furthermore, it is not convenient to adjust and control the angle, resulting in inconvenience in use. Utility Model Content

[0004] The purpose of this utility model is to provide a field surveying device for construction engineering cost, which solves the problem that the use of surveying instruments requires the use of other equipment such as level instruments, which makes it impossible to achieve coordinated use.

[0006] According to the aforementioned on-site cost surveying device for construction projects, a worm gear is fixedly connected to the lower middle part of the rotating rod, a worm is meshed on one side of the worm gear, and a knob is fixedly connected to the end of the worm.

[0007] According to the aforementioned on-site cost surveying device for construction projects, a bidirectional screw is rotatably connected to the center of the support platform, and threaded blocks are threadedly connected to both sides of the center of the bidirectional screw.

[0008] According to the on-site cost surveying device for construction projects, the support platform has grooves on both sides of the middle section, the two ends of the threaded block are slidably engaged with the grooves, and the tops of the two ends of the threaded block are fixedly connected to the clamping plate.

[0009] According to the above-mentioned on-site surveying device for construction engineering cost, a V-shaped block is fixedly connected to the inner side of the clamping plate, and a level is clamped between the V-shaped blocks.

[0010] According to the on-site cost surveying device for construction projects, a sliding rod is fixedly connected to the bottom center of the support block, and a sliding sleeve is slidably fitted in the middle of the sliding rod. The sliding sleeve and the support are rotatably fitted by a rotating rod.

[0011] According to the above-mentioned on-site surveying device for construction engineering cost, a surveying instrument is provided on the upper surface of the turntable, and an adjusting screw is threadedly connected to the middle of the fixed side plate, with one end of the adjusting screw engaging with the surveying instrument.

[0012] According to the on-site cost surveying device for construction projects, a pointed cone block is movably connected to the extension end of the support, and a horizontal bubble meter is fixedly connected to the middle of the front side of the support platform.

[0013] The above-mentioned solution has the following beneficial effects: This utility model comprises an adjusting screw, a bidirectional screw, a level, and a support platform. The adjusting screw rotates and comes into contact with the surveying instrument, achieving a secure connection. When the level needs to be fixed in place, it can be placed on the upper surface of the support platform. The bidirectional screw rotates, engaging with a threaded block to allow movement. The inner V-shaped block of the clamping plate then clamps and holds the level. This structure allows for the installation of both the surveying instrument and the level, enabling simultaneous operation and improving portability.

[0014] This utility model is equipped with a turntable, a worm gear, a worm wheel, and a rotating rod. When it is necessary to rotate the entire structure above the turntable, the knob at one end of the worm gear can be turned.
