Inspection well construction method

Abstract

The invention relates to a construction method of an inspection well. The construction method comprises the following steps: 1), putting up formworks for a well tube of the inspection well and pouringconcrete; 2, carrying out backfilling at the periphery of the well tube; 3, putting up formworks for a well ring; 4, pouring a rough ground surface; 5, disassembling the formworks; 6, mounting a wellbase and a well cover; and 7, pouring a net ground surface. The construction method has the beneficial effects that the well ring and the rough ground surface form a whole by the construction method,so that a deformation problem caused by external force is basically solved, the use state of the inspection well is improved, the compression and shearing resisting properties of a well opening partare improved, and the whole quality level of the inspection well is greatly improved; an umbrella-shaped support structure is convenient to fold and unfold and is stable, and compared with the groundtype support structure, the structure has the advantages that the ground does not need to be leveled, the weight of the structure is reduced, and construction is more convenient and labor-saving; anda locating framework can be used for multiple purposes, and the locating support not only performs locating and support functions, but also performs suspending and lifting functions in a side wall vibrating process.

Description

technical field [0001] The invention belongs to the field of inspection well construction, and in particular relates to a construction method of an integral inspection well. Background technique [0002] The construction of traditional inspection wells requires prefabricated reinforced concrete well circles in advance, and the well circles and rough ground are divided into two processes to complete. However, this traditional construction method has obvious disadvantages. Since the well ring and the ground are poured separately, it is difficult to form a whole with the surrounding ground, and cracks are easy to occur; the elevation of the well ring is difficult to adjust during installation, which will lead to installation difficulties and large labor requirements. The quality cannot be guaranteed; the prefabricated well ring is heavy and bulky and inconvenient to transport; the installation process has many procedures, takes a long time, is difficult, and the road surface qu...

However, this traditional construction method has obvious disadvantages. Since the well ring and the ground are poured separately, it is difficult to form a whole with the surrounding ground, and cracks are prone to occur; the elevation of the well ring is difficult to adjust during installation, which will lead to installation difficulties and large labor requirements. The quality cannot be guaranteed; the prefabricated well ring is heavy and bulky and inconvenient to transport; the installation process has many procedures, takes a long time, is difficult, and the road surface quality is poor, which reduces the service life
