Steel pipe piece for tunnel convenient to be spliced

Abstract

The invention discloses a steel pipe piece for a tunnel convenient to be spliced, which comprises a first steel pipe piece.Inserting block clamping grooves are formed in the top end and the bottom end of the interior of the first steel pipe piece correspondingly,the outer wall of one end of the first steel pipe piece is fixedly connected with an insertingclamping block, the inserting clamping blockis located on the other side of the first steel pipe piece,a plurality of bolt connecting grooves are formed in the other side of the first steel pipe piece, spring grooves are formed in the interiors of the top end and the bottom end of the inserting clamping block, and spring connecting blocks are inserted into the two spring grooves correspondingly. The steel pipe piecehas the achieved beneficial effects that the provided two connecting inserting blocks are connected with the inserting block clamping grooves in a matching and inserting mode, the inserting clamping block is inserted into a clamping block limit block and limited by a plurality of bolts, the two arranged spring connecting blocks can also limit, connection between the first steel pipe piece and a second steel pipe piece is achieved by repeatedly limiting, so that connection between the first steel pipe piece and the second steel pipe piece is more compact, and the problem of loose caused by rust on the welding position is avoided.

Description

technical field [0001] The invention relates to a steel pipe sheet, in particular to a steel pipe sheet for tunnels which is convenient for splicing, and belongs to the technical field of tunnel parts. Background technique [0002] Tunnels need to use a lot of steel pipes, and the connection between steel pipes is not a small problem, and in the existing technology, the connection between steel pipes is mostly welded connection, due to time Over time, the welding may appear rusty, and it is easy to loosen and fall off. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a steel pipe sheet for tunnels that is convenient for splicing, which solves the problem that tunnels need to use many steel pipe Small problem, and in the existing technology, the connection between the steel pipe sheet and the steel pipe sheet is mostly a welded connection. Due to the passage of time, the w...
