Description

一种竹复合综合管廊Bamboo composite integrated pipe gallery 【技术领域】[Technical Field]
本发明属于市政设施技术领域，更具体地，涉及一种竹复合综合管廊，该竹复合综合管廊是种无应力管廊。The invention belongs to the technical field of municipal facilities, and more particularly to a bamboo composite integrated pipe gallery, which is a kind of stress-free pipe gallery.
【背景技术】【Background technique】
管廊是建于城市地下用于敷设市政管线的市政设施。其集电力、通信、广电、燃气、给排水、热力等多种市政管线于一体，有效地利用了道路下的空间，节约地下空间资源，也杜绝了各专业管线分别不定期开挖，对道路通行和周边环境造成的影响，彻底解决了“马路拉链”、“空中蜘蛛网”等问题。The pipe gallery is a municipal facility built on the underground of the city for the laying of municipal pipelines. It integrates various municipal pipelines such as electric power, communication, radio and television, gas, water supply and drainage, and heat, effectively utilizing the space under the road, conserving underground space resources, and eliminating irregular excavation of various professional pipelines. The impact of the passage and the surrounding environment completely solved the problems of “road zipper” and “air spider web”.
目前，管廊不管是现浇式还是预制式，大多采用钢筋混凝土结构，但是这种结构耗费材料多，建设工程量大，施工周期长，造价高，越来越难以适应现代化城市建设的需求。At present, most of the pipe corridors are cast-in-place or prefabricated, and most of them use reinforced concrete structures. However, this structure consumes a lot of materials, has a large amount of construction work, has a long construction period, and is expensive, making it more and more difficult to adapt to the needs of modern urban construction.
竹材料是可再生的绿色环保材料，近年来随着竹缠绕复合相关技术的日益成熟(例如，中国专利文献CN105546230A、CN101571213A、CN202327397U、CN 104033724A等)，竹缠绕相关制品由于其制备成本低、制品性能良好、制备方法绿色环保的特点，受到了越来越多生产企业和消费者的重视，市场占有率也不断提高。竹缠绕复合制品，如竹缠绕复合管道、电线杆、管廊、料仓、高铁车厢外壳等，可广泛的应用于各行各业。Bamboo materials are renewable green materials. In recent years, with the increasing maturity of bamboo-wound composite technology (for example, Chinese patent documents CN105546230A, CN101571213A, CN202327397U, CN 104033724A, etc.), bamboo-wound related products are low in production cost and products. The characteristics of good performance and green preparation of environmental protection have been paid more and more attention by manufacturers and consumers, and the market share has been continuously improved. Bamboo-wound composite products, such as bamboo-wound composite pipes, utility poles, pipe porches, silos, and high-speed rail casings, can be widely used in various industries.
竹复合管廊(竹复合综合管廊)作为一种新型管廊(如中国专利申请CN105042213A、CN105064399A等)，由于其采用生物基材料，尤其是竹材料这种可再生的绿色环保材料，造价低，并具有绿色环保、环境友好的特点。尽管竹复合管廊具有绿色环保的优点，但由于管廊的大口径、且埋于地下的特点，应用时内部应力、以及外部压力大，如何提高竹复合管廊的 强度与稳定性、延长使用寿命仍是竹复合管廊应用中不可忽视的问题。Bamboo composite pipe gallery (bamboo composite integrated pipe gallery) as a new type of pipe gallery (such as Chinese patent application CN105042213A, CN105064399A, etc.), due to its use of bio-based materials, especially bamboo materials, such renewable green materials, low cost It is green and environmentally friendly. Although the bamboo composite pipe gallery has the advantages of green environmental protection, due to the large diameter of the pipe gallery and the characteristics buried in the ground, the internal stress and external pressure are large when applied, how to improve the bamboo composite pipe gallery Strength and stability, and prolonged service life are still issues that cannot be ignored in the application of bamboo composite pipe gallery.
【发明内容】[Summary of the Invention]
