Pressure steel pipe embedded structure

Abstract

The invention discloses a pressure steel pipe embedded structure. The pressure steel pipe embedded structure comprises pressure steel pipes, wherein two pressure steel pipes are provided; a buffer plate is arranged between the two pressure steel pipes, and is fixed between the two pressure steel pipes; a backfill grouting pipe is additionally arranged between the two pressure steel pipes, is vertically arranged between the two pressure steel pipes, and penetrates through the buffer plate; the top and the bottom of the backfill grouting pipe both extend into the pressure steel pipes; a drain plate is mounted on the lower surface of one pressure steel pipe, and is provided with a drain tank corresponding to the backfill grouting pipe; and the drain pipe is connected with the pressure steel pipes through fixed clamps. The pressure steel pipe embedded structure can preferably perform the block grouting, has no need to block a grouting hole after the grouting construction is finished, has excellent drain performance and buffer performance, and can preferably bear the pressure; and in addition, the pressure steel pipe embedded structure can preferably solve the empty problem between backfill concrete and the steel pipes, so that the steel pipe operation safety is improved, and the embedded performance is further enhanced.

Description

technical field [0001] The invention relates to a pre-embedded structure, in particular to a pre-embedded structure of a penstock steel pipe. Background technique [0002] During the construction of buildings, various construction equipment will be used for construction, and the threaded steel rear anchor embedded part is one of them. Because many pipes and steel plates are needed during construction, if the construction is not protected and the construction is carried out reasonably, it is easy to crack the weld seam of the pipe due to excessive vibration frequency or excessive vibration amplitude, causing the slurry in the pipe to flow out or even threaten The problem of staff safety, at the same time, if the steel plate cannot be well embedded in protection. The general steel pipe pre-embedded structure is prone to clogging, which will affect the grouting effect in the later stage, and lead to long construction period, complicated process, large blindness, high engineeri...
