Construction technology for installing directly-buried-section reinforced concrete drainage pipelines

Abstract

The invention relates to a construction technology for installing directly-buried-section reinforced concrete drainage pipelines. During pipe laying operation, a lifting arm on single pipelines is adopted for hoisting the single pipelines in a storage box into a pipe pit at a time, and therefore, the construction technology shortens the time for erecting a crane compared with the mode of using thecrane, and is labor-saving and high in efficiency compared with the mode of manual pipe laying operation. In addition, the situation that when drainage pipelines are arranged at the two sides of thepipe pit in the length direction of the ditch pipe pit in advance, the drainage pipes may be insufficient or excessive is also avoided, and the construction efficiency is furthermore improved. An earth fill mechanism follows pipeline installing equipment to move and pushes mounds at the two sides of the pipe pit into the pipe pit to position the single pipelines, thus stability of the single pipelines is maintained, and deviation of the directly-buried section is avoided. After all the single pipelines are laid, pipe pit backfilling can be carried out after the airtightness of the single pipelines is judged by means of a closed water test, and then installation of the directly-buried-section reinforced concrete drainage pipelines is completed.

Description

technical field [0001] The technical field to which the present invention relates, in particular, relates to a construction technique for installing a reinforced concrete drainage pipeline in a directly buried section. Background technique [0002] At present, the urban drainage pipe network is an indispensable and important infrastructure for modern cities, a basic industry with overall and leading influence on urban economic development, the backbone of urban water pollution prevention and control, urban drainage and flood control, and a measure of the level of modern cities. important sign. [0003] The construction method of the existing drainage pipeline is generally to excavate the pipe pit with an excavator before laying the road, then manually cooperate with the excavation, then put the pipe into the dug pipe pit for splicing, and finally backfill with soil. [0004] The above-mentioned existing technical solutions have the following defects: in the operation of low...

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: in the operation of lowering the pipe, the drainage pipes are generally arranged on both sides of the pipe pit along the length direction of the pipe pit, and then mechanically closed by a crane or through ropes, crowbars, etc. The overall construction efficiency is low due to the manual lowering of the pipe with the cooperation of tools, so there is room for improvement
