Description
技术领域technical field
本发明涉及岩土工程领域，尤其涉及一种综合管廊预制台车及管廊预制方法。The invention relates to the field of geotechnical engineering, in particular to a comprehensive pipe gallery prefabrication trolley and a pipe gallery prefabrication method.
背景技术Background technique
城市地下管线是指城市范围内供水、排水、燃气、热力、电力、通信、广播电视、工业等管线及其附属设施，是保障城市运行的重要基础设施和“生命线”。近年来，随着城市快速发展，地下管线建设规模不足、管理水平不高等问题凸现，一些城市相继发生大雨内涝、管线泄漏爆炸、路面塌陷等事件，严重影响了人民群众生命财产安全和城市运行秩序。Urban underground pipelines refer to pipelines and ancillary facilities for water supply, drainage, gas, heat, electricity, communications, radio and television, industry, etc. within the city, and are important infrastructure and "lifelines" to ensure urban operation. In recent years, with the rapid development of cities, problems such as insufficient scale of underground pipeline construction and low management level have emerged. In some cities, incidents such as heavy rain and waterlogging, pipeline leakage and explosion, and road subsidence have occurred one after another, which have seriously affected the safety of people's lives and property and the order of urban operation. .
传统的城市地下管线各自为政地敷设在道路的浅层空间内，因管线增容扩容不但造成了“拉链路”现象，而且导致管线事故频发，极大地影响了城市的安全运行。目前，我国城镇化进程十分迅速。为提升管线建设水平，保障市政管线的安全运行，有必要采用新的管线敷设方式-综合管廊。综合管廊工程是指在城市道路下面建造一个市政共用隧道，将电力、通信、供水、燃气等多种市政管线集中在一体，实行“统一规划、统一建设、统一管理”，以做到地下空间的综合利用和资源的共享。Traditional urban underground pipelines are laid separately in the shallow space of the road. The expansion of pipelines not only causes the phenomenon of "pull links", but also leads to frequent pipeline accidents, which greatly affects the safe operation of the city. At present, my country's urbanization process is very rapid. In order to improve the level of pipeline construction and ensure the safe operation of municipal pipelines, it is necessary to adopt a new pipeline laying method - comprehensive pipeline gallery. The comprehensive pipe corridor project refers to the construction of a municipal shared tunnel under the urban road, which integrates various municipal pipelines such as electricity, communication, water supply, and gas, and implements "unified planning, unified construction, and unified management" to achieve underground space. Comprehensive utilization and resource sharing.
城市地下综合管廊的施工方法主要分为明挖施工和暗挖施工，但普遍存在现浇施工速度慢、工艺复杂、质量不易保证等缺点，不利于进行规模化大批量生产。The construction methods of urban underground comprehensive pipe corridors are mainly divided into open-cut construction and underground excavation construction, but there are generally disadvantages such as slow construction speed, complicated process, and difficult quality assurance of cast-in-place construction, which is not conducive to large-scale mass production.
