Fast packaging and pouring device for concrete pipelines and construction method of fast packaging and pouring device for concrete pipelines

Abstract

The invention belongs to a fast packaging and pouring device for concrete pipelines and a construction method of the fast packaging and pouring device for the concrete pipelines. The device comprisesthe concrete pipelines, fixing nuts, upper ring die plates, lower ring die plates, clamping plates used for fixing end heads of the two concrete pipelines which are connected in series at equal intervals, and the concrete pipelines. The walls of an inner end opening and an outer end opening of each concrete pipeline are provided with two ring-shaped clamping grooves, and the walls of the inner endopening and the outer end opening of each concrete pipeline are rough surface walls. The method includes the steps that the clamping plates are used for fixing the end heads of the two concrete pipelines which are connected in series, then cement mortar is poured in a pouring space defined by the inner end walls of the upper ring die plates, the inner end walls of left and right movable ash distributing die channels, the inner end walls of left and right fixed ash distributing die channels, the clearance of openings of the two concrete pipelines and the upper end walls of the lower ring die plates. By means of the fast packaging and pouring device for the concrete pipelines and the construction method of the fast packaging and pouring device for the concrete pipelines, butt joint openingsof the adjacent concrete pipelines can be rapidly packaged, strengthened and connected, and the beneficial effects that the structure and method are simple and practical, time and force are saved, the construction cost is low, the speed is high, and the quality and the use effect are good are achieved.

Description

technical field [0001] The invention belongs to a concrete pipeline rapid encapsulation pouring device and a construction method thereof. Background technique [0002] Prefabricated concrete pipes are widely used in the construction of urban water supply and drainage pipelines. The diameter of concrete pipes is large, and the inner diameter is between 1.5 and 2 meters. Concrete pipes are laid at the bottom of the excavated trench. After the concrete pipeline is installed, the joints of the adjacent concrete pipelines are only jointed with cement, and then the trench is backfilled with soil. Because the diameter of the concrete pipe is too large, too heavy, the operating space of the enveloping width is narrow, the construction is inconvenient, and the load in the concrete pipe is uneven, especially the joint is too low, which is easy to cause the concrete pipe to sink, and the joint is dislocated and leaks. The water leakage accelerates the subsidence of the ground at the ...

Because the diameter of the concrete pipe is too large, too heavy, the operating space of the enveloping width is narrow, the construction is inconvenient, and the load in the concrete pipe is uneven, especially the joint is too low, which is easy to cause the concrete pipe to sink, and the joint is dislocated and leaks. Water leakage accelerates the subsidence of the ground at the lower end of the concrete pipe, leading to the rupture of the concrete pipe and causing interruption of urban water supply and drainage
