Supporting and protecting device for municipal pipe network trench excavation

Abstract

The invention discloses a supporting and protecting device for municipal pipe network trench excavation. The supporting and protecting device comprises a plurality of lower positioning seats, wherein grooves are formed in the upper side ends of the lower positioning seats and are used for containing embedded pipes, upper positioning seats are arranged above the embedded pipes, grooves which are matched with the embedded pipes are formed in the lower end faces of the upper positioning seats, the embedded pipes are clamped between the upper positioning seats and the lower positioning seats, side protection plates are arranged on the side walls of the grooves which are used for installing the embedded pipes, the two sides of the upper positioning seats are connected to the side protection plates through at least one upper supporting and protecting device, and the two sides of the lower positioning seats are connected to the side protection plate through at least one lower supporting and protecting device. The supporting and protecting device has the advantages of convenience in installation during construction, fast construction progress and high structural stability, during construction backfilling, only the remaining lower positioning seats and pipelines are backfilled in trenches, other parts can be reused after being removed, and cost losses are reduced.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a support and protection device for excavating municipal pipe network trenches. Background technique [0002] With the development of society, more and more attention is paid to the layout of pipe networks in cities. In order to meet the needs of urban water supply, drainage, gas, heating, power supply, communication and other urban pipeline systems to play a corresponding role smoothly, it is necessary to The composition, layout, main structures, pipes, etc. of the pipeline system are planned to be buried and surveyed, and the urban engineering pipelines are comprehensively marked and recorded. [0003] At present, after the excavation of deep trenches at the bottom of the existing municipal pipe network, wooden baffles are generally used to overlap the diagonal braces with steel pipe components, or direct cast-in-place concrete baffles. The installation efficiency...
