Embodiment Construction
[0022] The present invention will be further described below in conjunction with specific examples. It should be understood that the cited examples are only used to illustrate the present invention, and are not intended to limit the scope of the present invention.
[0023] Such as figure 1 and figure 2 As shown, a telescopic retaining ring for municipal engineering. The telescopic retaining ring 1 includes a telescopic upper ring 11 and a telescopic lower ring 13. The telescopic upper ring 11 and the telescopic lower ring 13 are sequentially passed through from top to bottom, and the diameters are successively reduced. The lower inner edge of the telescopic upper ring 11 is provided with an inner boss 41, the upper outer edge of the telescopic lower ring 13 is provided with an outer boss 42, and the lower outer edge of the telescopic lower ring 13 is provided with a limit stop ring 43, and the limit stop ring 43 is tapered Limit retaining ring, the inner boss 41 and the oute...

The invention relates to a retractable retainer ring for municipal engineering, an inspection well comprising the retractable retainer ring and a method for applying the retractable retainer ring. The retractable retainer ring comprises an upper retractable ring and a lower retractable ring. The upper retractable ring and the lower retractable ring are sequentially and penetratingly arranged from top to bottom, an inner boss is arranged at the lower inner edge of the upper retractable ring, an outer boss is arranged at the upper outer edge of the lower retractable ring, a limiting retainer ring is arranged at the lower outer edge of the lower retractable ring, the inner boss and the outer boss are fastened with each other, and the diameter of a cover plate is larger than the outer diameter of the upper retractable ring. The retractable retainer ring for municipal engineering, the inspection well and the method have the advantages that backfill cannot leak into the well by the aid of the retractable retainer ring, the retractable retainer ring can be downwardly contracted along with a soil layer when the soil layer is compacted by a road roller, only needs to be upwardly lifted when soil is required to be filled again, and accordingly can be reused for construction, and the service life of the inspection well is prolonged; the plain soil can be compacted by the retainer ring, so that the bearing capacity of the retractable retainer ring and the bearing capacity of the inspection well can be improved, and the construction times can be effectively reduced.
Description
technical field [0001] The invention relates to the technical field of inspection wells, in particular to a telescopic retaining ring for municipal engineering, an inspection well and a usage method thereof. Background technique [0002] At present, science and technology are constantly advancing, society is developing rapidly, and new products are constantly being developed. The construction of the original municipal pipeline system cannot meet the needs of development, especially the pipeline inspection wells, whether it is traditional brick wells or today's cement concrete module wells, or plastic inspection wells are not well protected during construction. Check that the well collapsed or deformed seriously. Due to the energy saving, environmental protection and corrosion resistance of plastic inspection wells, it has been gradually accepted by the society. However, the short service life and low reusability of plastic inspection wells have always troubled people, seri...
