The invention discloses an accurate positioning device for the end of a deep pipeline and a construction method thereof. The positioning device includes a positioning piece and a detachably connected casing in the positioning piece. The positioning piece is a positioning bracket in a frame structure and is detachably connected in the positioning bracket. The positioning plate; the positioning bracket includes a column arranged in a rectangle, a cross bar connected to the long direction of the column, and a connecting rod connected to the short direction of the column, and the upright column, the cross bar and the connecting rod can be detachably connected; The setting is conducive to the installation of pipelines of different professions and sizes in units, and the casing is also divided into vertical sections, horizontal sections and arc sections according to the direction of the pipelines, which can meet the installation requirements of different pipelines as much as possible; through the position of the pipeline to be installed The advance deepening and the pre-numbering of the casing can clarify the installation position of the pipeline; through the setting of the positioning bracket, it is convenient to classify and fix the pipeline, and it is convenient to adjust according to the actual situation on site.
Description
technical field [0001] The invention belongs to the field of building construction, and in particular relates to an accurate positioning device for the end of a deep pipeline and a construction method thereof. Background technique [0002] With the rapid development of the construction industry, the requirements for aesthetics, safety, functionality, economic benefits, energy conservation and environmental protection of buildings are getting higher and higher; underground buried pipelines are an important link in the electrical installation process. [0003] In the past, the construction of electrical pipelines was carried out directly according to the drawings of the design institute. The pipelines crossed disorderly, and there were serious collisions among various disciplines, which led to repeated coordination and demolition on site, which was not only time-consuming and laborious, but also affected the aesthetics. Amusement parks, movie theaters and other cultural and to...
