Description

Technical Field

[0001] The present invention relates to the technical field of inspection wells, and particularly to a caliper for controlling the appearance quality of plastering of inspection wells. Background Art

[0002] During the plastering process after the masonry of circular inspection wells in municipal road projects and highway projects, there is a large waste of plastering materials, the appearance quality of the plastered surface is poor after the construction is completed, and it is not easy to control the plastering quality of the inner and outer well walls of circular inspection wells. Currently, for the inner and outer wall plastering after the masonry of circular inspection wells in municipal road projects and highway projects, the plastering quality is poor. The current process on the construction site is the traditional manual plastering construction with a trowel. However, this process is not suitable for constructing an arc-shaped base surface. It is often time-consuming and laborious during the construction process, with low work efficiency, and the completed plastered surface is not smooth, resulting in a large water flow resistance in the inspection well and poor appearance quality. There is no reference line during the construction process, and the structural deviation formed during the masonry of the well wall cannot be compensated after completion. The absence of a reference line also leads to a large waste of plastering materials. Summary of the Invention

[0003] In order to overcome the above technical problems, the purpose of the present invention is to provide a caliper for controlling the appearance quality of plastering of inspection wells, which is simple to install and disassemble during use, does not require more labor and machinery, and is convenient and fast. During construction, the workers for the plastering process of the inspection well do not need to smear repeatedly, shortening the plastering time, and greatly improving the construction efficiency, saving labor costs. After the construction is completed, the plastered well wall is smooth and flat, no re-plastering is required, the density is good, the appearance quality is excellent, and it effectively prevents water from seeping outside the well, reducing the water flow resistance in the well and enabling the accumulated water in the well to be drained quickly. Compared with the traditional plastering construction process, this equipment saves labor, improves the construction quality, and the added equipment can be reused repeatedly. During the plastering process after the masonry of circular inspection wells in municipal road projects and highway projects, it can effectively improve the plastering quality of the inspection wells and enhance the durability of the inspection wells. By using this plastering caliper, the phenomenon of "unevenness" on the surface of the circular well wall of the inspection well caused by traditional manual plastering can be effectively avoided, greatly saving plastering materials and ensuring the plastering quality.

[0004] The purpose of the present invention can be achieved through the following technical solutions:

A number of rows of bolt holes are equidistantly arranged on the shaped steel scraper. The bolt holes are adapted to the bolts. Arc-shaped steel sheets are fixedly installed on both sides of the shaped steel scraper.

[0007] As a further scheme of the present invention: both sides of the arc-shaped steel sheet are set into an arc-shaped structure with a width of 50 mm and a length the same as that of the shaped steel scraper. A connecting plate connected to the shaped steel scraper is arranged in the middle of the arc-shaped steel sheet.

[0008] As a further scheme of the present invention: the thickness of the shaped steel scraper is 5 mm, and small grooves are arranged on both side edges of the shaped steel scraper in the long side direction.

[0011] As a further solution of the present invention, the processing method of the quality control caliper is as follows: after the masonry of inspection wells in municipal road engineering and highway engineering is completed, the construction of the plastering process for the inspection well wall is carried out. Before construction, the base of the well wall is treated, and the well wall is watered and moistened before applying the bottom ash. After the bottom ash has slightly solidified, a small amount of water is sprinkled on the surface of the bottom ash to moisten it, and then the surface ash is applied. Then, the assembled plastering and leveling ruler is placed at the center position of the wellbore. The horizontal adjustment plate is adjusted to an appropriate height, and then the vertical connection head is adjusted so that the shaped steel scraper is in an appropriate position, and then the surface ash is leveled along the well wall. After scraping flat, an arc-shaped steel sheet is installed on the edge of the shaped steel scraper, and finally the plastering is finished and polished. After completion, the plastering and leveling ruler is removed, and the plastering layer is kept moist and heat-insulated for 7 days in time after coagulation.

[0012] The beneficial effects of the present invention: it is simple to install and disassemble during use, without the need to invest more labor and machinery, and is convenient and fast. During construction, the workers for the plastering process of the inspection well do not need to smear repeatedly, which shortens the plastering time, greatly improves the construction efficiency, and saves labor costs. After construction, the plastering of the well wall is smooth and flat, without the need for re-plastering, with good density and excellent appearance quality, and effectively prevents water from seeping outside the well, reducing the water flow resistance in the well, so that the accumulated water in the well can be quickly discharged. Compared with the traditional plastering construction process, this equipment saves labor, improves the construction quality, and the added equipment can be repeatedly put into use. During the plastering process after the masonry of circular inspection wells in municipal road engineering and highway engineering is completed, it can effectively improve the plastering quality of the inspection wells and improve the durability of the inspection wells. By using this plastering caliper, the phenomenon of "unevenness" on the surface of the circular well wall of the inspection well caused by traditional manual plastering can be effectively avoided, greatly saving plastering materials and ensuring the plastering quality.
