Problems solved by technology
[0002] At present, the following problems will occur in the process of casing construction in the densely populated area of pipelines passing through the floor: the primary structure of the main body is constructed quickly, and the requirements for the pre-embedded construction of the casing are high; the vertical position deviation of the casing passing through the floor is large; The space is small, the space is limited, and the installation of the casing through the floor is difficult; the construction method of leaving holes in the early stage and adding casing hanging holes in the later stage has a large hidden danger of water leakage; there are potential safety hazards in the welding and fixing process of ordinary direct-buried steel casings

Embodiment Construction
[0023] The content of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0024] Taking the installation project of Xi'an Children's Hospital Economic Development Zone as an example, its water supply and drainage, fire protection and medical pipelines are dense and intricate, with a tight construction period and a large amount of reserved pre-embedded volume.
[0025] The present invention provides a combined casing in a pipeline-intensive area, which includes a casing 1, the outer wall of the casing 1 is provided with a chute 101, and a plurality of chute 101 is provided along the circumference of the casing 1. Two adjacent chutes 101 have a circumferential interval of 90 degrees or 180 degrees; a connecting rod 102 is arranged in the chute 101, and the connecting rod 102 and the chute 101 can be fixed together by a locking nut 103; the casing 1 is provided with multiple, And according to the circumferential positio...

The invention mainly relates to the field of combined type sleeves, in particular to a combined type sleeve for a pipeline dense area and a construction method of the combined type sleeve. The device structurally comprises a sleeve, a sliding groove is formed in the outer side wall of the sleeve, a connecting rod is arranged in the sliding groove, the connecting rod and the sliding groove can be fixed together through a locking nut, a mechanical connection method is adopted, and the construction efficiency is improved on the premise that the position accuracy is guaranteed; according to the construction method, rapid insertion can be achieved before the steel bars are bound on the structure at a time, the construction period of reserving and pre-burying is shortened, and compared with the previous construction technology of reserving holes in the earlier stage and adding casing pipe hanging holes in the later stage, the hidden danger of leakage between the casing pipe and the structure in the pipeline dense area is eliminated through the construction method; and the installation and combination mode of threaded connection avoids the fire hazard in the field welding and fixing process of the directly-buried steel sleeve in the past, and the construction safety risk is reduced.
Description
technical field [0001] The invention mainly relates to the field of combined bushings, in particular to a combined bushing in a pipeline-intensive area and a construction method thereof. Background technique [0002] At present, the following problems will occur in the process of casing construction in the densely populated area of pipelines passing through the floor: the primary structure of the main body is constructed quickly, and the requirements for the pre-embedded construction of the casing are high; the vertical position deviation of the casing passing through the floor is large; Due to the small spacing and limited space, it is difficult to install the casing through the floor; the construction method of leaving holes in the early stage and adding casing hanging holes in the later stage has a large hidden danger of water leakage; there are potential safety hazards in the process of welding and fixing ordinary direct-buried steel casings on site.
