摘要: A pipe joint in which a seal body and a spacer are mounted from the insides of pipes, wherein: a spigot of one pipe is inserted into a socket of the other pipe; and an annular accommodation space is formed between the inner circumference of the socket and the outer circumference of the spigot. Inside the accommodation space are accommodated: a seal body for sealing the gap between the socket and the spigot; a push ring that presses the seal body to keep the seal body in a compressed state; and a spacer that maintains the interval between the push ring and the deep end of the socket in the pipe axial direction.

摘要: A construction management document creation device includes: a first input processing unit configured to repeat a process of assigning a unique pipe number and a unique joint number in association with pipe attribute information, and thereby generate pipe connection information from which connection relationship between laying pipes is identifiable based on the pipe number and the joint number, and pipe laying information from which a type and a laying position of each laying pipe are identifiable based on the pipe attribute information; a second input processing unit configured to generate assembled condition management information based on assembling procedure confirmation information and assembled condition evaluation information input for each pipe assembling section identified by the joint number; and a document generation processing unit configured to generate a construction management document including a daily construction report based on the pipe connection information, the pipe laying information, and the assembled condition management information.

摘要: Provided is a bending angle calculation method capable of saving a worker time and effort. The bending angle calculation method includes: an image capturing step (S1) of capturing an image of a pipe in which a first pipe and a second pipe are joined together by a joint; a derivation step (S3) of deriving, from the image, a laying direction straight line corresponding to a laying direction of the pipe; and a calculation step (S4) of calculating, as a bending angle at the joint, a crossing angle between a laying direction straight line of the first pipe and a laying direction straight line of the second pipe.
