Temporary supporting system in limited space and construction method
The invention discloses a temporary supporting system in a limited space and a construction method, which are characterized in that the temporary supporting system is arranged in a limited space state, the temporary supporting system is subjected to safety avoidance design in the horizontal and vertical depth directions at the same time, and then according to a priority order principle of lowest cost and convenience, the temporary supporting system is subjected to safety avoidance design in the horizontal and vertical depth directions; a supporting beam is selected, the rigidity parameter of the supporting beam is obtained, the maximum deformation amount of the supporting beam in different single-pile safety distances and different supporting beam rigidity states is calculated, and when the maximum deformation amount is smaller than the maximum allowable deformation amount, the steel pipe piles meeting the conditions and the pile inserting distance are determined; the medium-frequency vibratory hammer and the high-frequency vibratory hammer are adopted for construction during pile inserting and pile pulling construction, and the influence on peripheral pipelines and existing buildings can be completely reduced to the maximum extent.
本发明公开了一种有限空间下临时支承体系及施工方法，针对有限空间状态下，进行临时支承体系布置，所述临时支承体系在进行水平和竖直深度方向上同时做安全规避设计，然后根据成本最低和便利的优先级顺序原则，选择支承梁并获得其刚度参数，并计算其在不同单桩安全间距和不同支承梁刚度状态下的最大变形量，当满足低于最大允许变形量的条件下确定符合条件的钢管桩及插桩间距；本发明在插桩和拔桩施工时分别采用中等频率和高频振动锤施工，能完全最大化降低对周边管线和既有建/构筑物的影响。
