Embodiment Construction
[0012] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.
[0013] A method for making super-large-diameter common trench pipe gallery on site, which includes the following steps in sequence: (1) Welding socket steel plates and socket steel plates into socket rings and socket rings according to pre-designed dimensions, and raising the rings in a rounding machine , so that the ovality is within the acceptable range, and the completed socket ring and socket ring are transported to the on-site production site near the construction site. (2) Weld the socket ring and the socket ring with longitudinal steel bars or steel bar skeletons. (3) Put the bottom mold on the working platform of the field production site, and install the inner mold on the bottom mold. (4) Put the welded socket ring into the designa...

The invention relates to a method for manufacturing a common ditch pipe gallery with ultra-large caliber in field, which comprises the following steps: forming a bell end steel ring and a spigot steel ring, forming a pipe core, winding the pipe core and grouting the pipe core, wherein the step of winding the pipe core comprises the steps of firstly mounting the pipe core on a pipe frame, winding the external wall of the pipe core in the same diameter for a circle on the winding position of the external wall of the pipe core by steel twisted cables, then intersecting two ends of the converged steel twisted cables, fixedly mounting the steel twisted cables at two ends of a jack with a clamping apparatus respectively, stretching the intersected steel twisted cables to the preset extension length in the same diameter by using the jack, fixing the intersection point of the steel twisted cables by an anchor block for finishing winding one steel twisted cable of the pipe core, and later circulating the winding operation according to the screw pitch set at the external wall of the pipe core, and finishing winding of the steel twisted cables of the complete pipe core. The method for manufacturing the common ditch pipe gallery with ultra-large caliber in field has the advantages of saving the cost of the conventional common ditch, along with short construction period and the like.
Description
technical field [0001] The invention belongs to the technical field of large-diameter common trenches, in particular to a method for making super-large-diameter common trench pipe galleries on site. Background technique [0002] The current pipe gallery is all cast on site. The pipe gallery is a cuboid structure. The wall of the rectangular pipe gallery is embedded with a steel skeleton. Due to the large external pressure load, the wall of the pipe gallery is relatively thick. The main function of the pipe gallery is to gather gas pipes, water supply pipes, drainage pipes, reclaimed water pipes, heating pipes, and communication cables; its advantages are: excavation at one time, centralized construction, avoiding repeated excavation of the same road section. The main construction and production steps of the pipe gallery include: slotting, support, precipitation, steel bar binding, formwork, concrete pouring, maintenance, formwork removal, and backfilling. The production pro...
