Description
Technical Field
The invention relates to a construction method for protecting translation of a large block partition underpinning of an engineering site, belonging to the technical field of integral translation of buildings.
Background
With the continuous acceleration of city construction in China, a large number of existing buildings need to be dismantled and rebuilt due to old city reconstruction, road planning, track construction and the like. However, due to the cultural relic protection requirement, many ancient sites cannot be dismantled and rebuilt according to the traditional mode, and only can be reserved in situ, which brings little obstruction to the development and utilization of urban space. In order to solve the contradiction between old city reconstruction, new city construction and historical ancient site protection, the concept of relocation protection adopted for ancient sites should be born.
Nowadays, china has many related engineering cases for site relocation protection, such as public bidding: shanghai Mazuo temple relocation protection engineering, shanghai Guanglin culture site relocation protection engineering, xuzhou Mingdian health site integral relocation engineering, and the like. The construction method adopted by the vestige protection projects is as follows: cutting the blocks, wrapping, hoisting and transporting the blocks by using glass fiber reinforced plastic and flexible materials, and finally assembling and restoring at a new site. The method has high cost and low efficiency, has high possibility of damaging historical information and cultural relic values, can not meet the requirements of the existing removal protection of numerous historical sites, and is particularly not suitable for the removal protection of large-sized rammed earth structures. Therefore, the ancient site is preferably moved and protected by adopting the related technical means of integral translation of the building.
The integral translation construction method of the building refers to a construction method for integrally shifting the building from an original site to a proper position for protection and utilization under the condition of not influencing the use function of the building so as to meet the requirements of urban construction planning and the like. The whole translation construction method of the building is mature, the maximum translation building area exceeds 2 ten thousand square meters, the weight reaches 3 ten thousand tons (Xixi bus station rotation translation project behind the mansion door), and the maximum translation construction method exceeds 15 floors (Tugong office building translation in the Laiwu development area of Shandong). However, the existing construction method is not suitable for the relocation protection of rammed earth historic sites which exist in China in large quantity. The construction method is difficult to set underpinning and translation tracks in the foundation, the underpinning structure for translation of a building is mainly underpinning of an upper structure or underpinning of a foundation, the tracks are mostly in the form of strip foundations or sleeper steel rails, the construction methods all need large-area excavation of the building foundation and are difficult to implement in the soil body.
In the protection of some cultural relic buildings, part of projects also adopt a jacking pipe underpinning construction method in a foundation, but only used for jacking projects (such as the jacking protection projects of wonder mountain palace buildings). The lower rail is not needed to be arranged in the jacking engineering, only the jacking counter-force platform with enough bearing capacity is needed to be arranged, and the method is easily realized by applying a pile foundation or an independent column foundation. But the construction of the low-cost underpinning and track double structure in the soil body has great technical difficulty. Meanwhile, a counter-force platform in the jacking engineering does not need to be moved, and when the site area is large and translation is needed for a long distance, a large amount of cost can be generated by arranging the full-length track.
In conclusion, in the research of the existing integral translation construction method of the building, a large research space and potential application value are provided for the relevant construction method of ancient site translation protection. In order to solve the conflict between social development planning and effective protection of the building site, a underpinning translation protection construction method suitable for rammed earth ancient sites is developed based on a whole building translation construction method, so that the historical landscape, cultural relic value and ancient engineering technical information of the rammed earth ancient sites are more completely protected, and the method has important historical culture inheritance significance undoubtedly.
