More Information
Summary:The invention discloses an inner-support-free frost-heaving-resistant water-rich depth foundation pit support structure which comprises a water-rich area roadbed, a foundation pit support mechanism, a pouring reinforcing mechanism and a frost-heaving-resistant mechanism. The top of the water-rich area roadbed is drilled to form a foundation pit, and the foundation pit enclosure mechanism is installed in the foundation pit of the water-rich area roadbed and used for forming enclosure reinforcement on the foundation pit; the pouring reinforcing mechanism is mounted in the foundation pit support mechanism; during use, the reinforcement cage and the enclosure cylinder are arranged in the enclosure pile foundation, concrete grout is poured into the square pipe opening in the inner wall of the enclosure cylinder, the concrete grout passes through the extension pipe and the pouring channel and then is discharged into the enclosure pile foundation from the concrete injection pipe, and the reinforcement cage is filled
