Description

Installation state measuring device of prefabricated pipe culvert

technical field

The utility model relates to the technical field, in particular to a pipe culvert prefabricated component installation state measuring device which improves the measurement efficiency and accuracy of the pipe culvert prefabricated component state data.

Background technique

Precast concrete pipe culvert is a prefabricated reinforced concrete structure with the characteristics of factory prefabrication and on-site assembly. Compared with the cast-in-place construction method, it has the advantages of improving efficiency, reducing workers, shortening the construction period, and being environmentally friendly.

Prefabricated pipe culvert components can be widely used in underground projects such as urban comprehensive pipe gallery, cable tunnel, water storage tank, underground passage and drainage facilities. Under normal circumstances, rubber waterstops are pre-buried at both ends of the box culvert. After the two sections of the box culvert are connected, the waterstops are squeezed tightly, and then the two sections of the box culvert are fixed in a certain way to prevent water leakage between the sections.

In order to ensure that the structures assembled by prefabricated pipe culverts meet the requirements of structural safety and functional functions, the assembly accuracy of prefabricated components must be guaranteed. That is to ensure that after the prefabricated components are assembled, their positions and postures meet the requirements of the design documents. Therefore, after each prefabricated component is assembled, it must be measured to check whether its position and attitude deviation meet the requirements.

At present, during the assembly and construction of prefabricated pipe culvert components, the measurement work mainly relies on manual operation of measuring instruments to measure the position and attitude of prefabricated components. The problems of manual measurement are as follows: First, the manual measurement process is cumbersome. The manual placement of equipment, leveling, and reading and other processes take up a long time in the construction process and reduce the construction efficiency; secondly, manual measurement can only be done after the components are assembled. During the assembling process, the measurement cannot be carried out, therefore, the position of the component can only be adjusted repeatedly by hoisting and repeated measurement, which further reduces the construction efficiency. Thirdly, manual measurement relies on manual ruler or prism measurement, and the operation error is large, which limits the assembly accuracy. Finally, manual measurement requires a separate measurement team to be responsible for measurement work, which increases personnel costs.
