Vacuum preloading construction process
The invention provides a vacuum preloading construction process which comprises the following steps: constructing a plurality of drainage plates on a sand cushion layer of a soft soil foundation after the sand cushion layer of the soft soil foundation is constructed, and installing a plurality of groups of filter pipes on the plurality of drainage plates; a sealing wall is firstly constructed on the periphery of the soft soil foundation, and then a film pressing groove is constructed above the sealing wall; sealing film construction is conducted on the soft soil foundation, the sealing film is manually pressed into the film pressing ditch, water covering is conducted in time, and the sealing performance of the film pressing ditch is guaranteed; and the soft soil foundation is subjected to vacuumizing construction. The sealing wall, the sealing film, the film pressing groove and the covering water are used for sealing the soft soil foundation together, and the sealing wall and the film pressing groove are formed in the range of the separation embankment, so that sealing of the soft soil foundation can be effectively achieved, and vacuumizing consolidation treatment of the soft soil foundation is facilitated.
本发明提供了一种真空预压施工工艺，包括：对软土地基砂垫层施工后，在软土地基砂垫层施工若干排水板，若干排水板上安装多组滤管；在软土地基的外围先施工密封墙，然后在密封墙上方施工压膜沟；对软土地基密封膜施工，密封膜人工压入压膜沟，并及时进行覆水，保证压膜沟的密封性；对软土地基抽真空施工。本发明采用密封墙、密封膜、压膜沟和覆水共同对软土地基密封，并且密封墙和压膜沟开设在隔堤范围内，能够有效实现对软土地基的密封，便于对软土地基抽真空固结处理。
