The protective structure comprises two opposite cement mixing pile walls. The cement mixing pile walls are formed by connecting a plurality of cement mixing piles in the radial direction. An underground pipe gallery containing cavity is formed between the two cement mixing pile walls. The protective structure can be used for protection of the underground pipe gallery, and displacement of the underground pipe gallery in the horizontal direction or settling of the underground pipe gallery in the vertical direction is avoided.
Description
Technical field
The invention belongs to technical field of buildings, relate to a kind of underground pipe gallery safeguard structure, be applicable to protect underground pipe gallery.
Background technology
Underground pipe gallery is also known as common trench, and it implements unified planning, design, construction and maintenance, is built in Urban Underground for laying the public utility of municipal public use pipeline.Refer at Urban Underground for concentrating the public tunnel laying the municipal pipelines such as electric power, communication, radio and television, feedwater, draining, heating power, combustion gas.
As far back as the '20s in last century, the pipelines such as electric power, phone, water supply and coal gas, just under the arterial road that nine sections, center, city is regional, are concentrated and are laid, define Tokyo Article 1 underground pipe gallery by Tokyo, Japanese capital municipalities.After this, " about building the special measure method of common trench " of within 1963, formulating, defining Japanese relevant departments from legal perspective need and the main trunk road infrastructure " common trench " that future may block up large at the traffic volume.The Tokyo national highway office of Transport Ministry subordinate is responsible for the Construction and management of area, Tokyo trunk line underground pipe gallery, and the underground pipe gallery of secondary main line is then responsible for by Tokyo construction bureau.
The pipe gallery of more than 1000 meter was just laid as far back as 1958 in Beijing under the Tian'anmen Square.Within 2006, build up the modern pipe gallery of China mainland area Article 2 in West, Zhong Guan-cun.This pipe gallery main line is long 2 kilometers, a line length 1 kilometer, comprises the municipal pipelines such as water, electricity, hot and cold, combustion gas, communication.1994, Shanghai City government planning built pipe gallery---the Pudong New District Zhang Yanglu pipe gallery that continent Article 1 is largest, distance is the longest.This pipe gallery total length 11.125 kilometers, has accommodated four kinds of urban pipelines such as feedwater, electric power, information and coal gas.The Jiading District Anting New Town pipe gallery system that the exemplary underground pipe gallery engineering (first phase) of Songjiang new city and " ring adds a line " are always about 6 kilometers has also been built up in Shanghai.The Suzhou Industrial Park infrastructure construction that China and Singapore develop jointly, through the exploitation of 10 years, also began to take shape in underground utilities corridor.
State Council pays much attention to advance the construction of Urban Underground pipe gallery, successively print and distribute since 2013 " State Council is about the suggestion strengthening urban infrastructure construction ", " General Office of the State Council is about the instruction strengthening City Buried Pipeline implementation management ", disposed and carry out Urban Underground pipe gallery construction pilot work.
Chinese patent literature discloses a kind of integrated form underground pipe gallery [application number: 201410559745.1] with compensation arrangement, comprise some tube coupling weather strips and some end to end tube coupling unit, described tube coupling weather strip is located between adjacent described tube coupling unit, described tube coupling unit comprises tube coupling and some pipelines be arranged in parallel, described pipeline is located on the bottom surface of described tube coupling inside by holder, described tube coupling two ends are respectively equipped with the tube coupling retractable connecting tube suitable with described tube coupling shape, described pipe ends is respectively equipped with pipeline extension tube connector, described tube coupling retractable connecting tube is provided with flange one away from one end of described tube coupling, described pipeline extension tube connector is provided with flange two away from one end of described pipeline.Such scheme effectively reduces the difficulty of construction and installation, improves the installation effectiveness of piping lane and pipeline, saves a large amount of engineering time and expense, and prefabricated profiled tube coupling supporting capacity is large simultaneously, and resistance to compression is effective.But, to have ignored around piping lane soil property to the protective action of piping lane.
