Vacuum surcharge combined preloading construction method
The invention relates to the field of soft foundation reinforcement treatment, in particular to a vacuum surcharge combined preloading construction method which comprises the following steps that a vertical drainage body and a horizontal drainage body which are connected with each other are arranged in a soft foundation area; a plurality of sealing films are laid on the upper side of the soft foundation area in the mode that the peripheries are mutually lapped and fixed; spraying a quick-setting rubber asphalt waterproof coating at the joint of the adjacent sealing films to enable the sealing films to be connected with a sealing sheet, and fixing the periphery of the sealing sheet to the periphery of the soft foundation area; the soft foundation area under the sealing film is vacuumized through the horizontal drainage body; and carrying out preloading construction after the vacuum degree under the sealing film meets the requirement. The sealing structure has the advantages that the probability of breakage of the sealing film can be reduced, so that the sealing performance of the sealing film is guaranteed, and the construction stability is improved.
本申请涉及软基加固处理的领域，尤其是涉及一种真空堆载联合预压施工方法，包括以下步骤：在软基区域设置相互连接的竖直排水体与水平排水体；将多个密封膜采用周边相互搭接固定的方式铺设于软基区域上侧；在相邻密封膜连接处喷涂速凝橡胶沥青防水涂料，使密封膜连接形密封片材，并将密封片材的四周固定于软基区域周边；通过水平排水体对密封膜下软基区域内抽真空；待密封膜下真空度达到要求后进行堆载预压施工。本申请具有能够减少密封膜破裂的几率，从而保证密封膜的密封性以提高施工稳定性的效果。
