The invention discloses a connecting mechanism used for concrete box culvert splicing. The connecting mechanism comprises an annular main body which can be arranged at the joint of two concrete box culverts in a sleeving mode; a plurality of grouting grooves are formed in the circumference of the annular main body at intervals, and the grouting grooves are communicated with an inner cavity of the annular main body through flowing holes so as to enable the concrete slurry in the grouting grooves to enter the joints of the inner wall of the annular main body and the concrete box culverts; a plurality of fixing holes are formed in the side wall of the annular main body, a fixing piece is installed in each fixing hole, and the bottoms of the fixing pieces can abut against the concrete box culverts. The connecting mechanism used for the concrete box culvert splicing can stably and quickly make the concrete box culverts connected.
Description
technical field [0001] The invention relates to concrete box culvert accessories, in particular to a connection mechanism for splicing concrete box culverts. Background technique [0002] Concrete box culvert refers to a culvert built with reinforced concrete box-shaped pipe joints. The concrete box culvert consists of one or more square or rectangular sections. At present, the processing of concrete box culverts can be made by pouring on site, but it can also be made into prefabricated box culverts in sections, and then reproduced as splicing through connecting mechanisms. The concrete box culvert made by pouring on site has excellent structural stability, but it has the disadvantages of cumbersome operation and inconvenient construction; the concrete box culvert made by splicing is easy to operate, but the structure of the splicing is generally unstable, which leads to mechanical properties. Poor defect. Contents of the invention [0003] The object of the present inve...
