摘要: An engineering method for reinforcing and lifting a sunken foundation of a residential building includes stratigraphic structure, conducting a curtain reinforcement, reinforcing and strengthening a shallow layer, reinforcing a deep layer, steadily lifting an intermediate layer, and reinforcement supports of the composite foundation, the shallow layer reinforcement and strengthening adopts a progressive layered reinforcement process, the foundation slab of the building is reinforced with grouting to form the reinforcement body of an integral raft composite foundation. A support of the composite foundation similar to the pile foundation is constructed under four corners of the building and under the main load-bearing walls of the room. A structure supporting the upper load is formed through repeated retreating and progressive grouting.

摘要: A method for reinforcing soft ground by post-grouting combined with pressurized vacuum preloading is proposed, by pre-burying prefabricated vertical drains and air-boosted pipes in granular material piles, and the air-boosted pipes are used as grouting pipes to reduce the number of times of piling, which not only improves the construction efficiency, but also reduces the structural disturbance of the soil and the influence of smear effect, thus reducing the impact on the radial permeability and the radial consolidation coefficients. The method does not use geotextile bags for granular materials, which can avoid the problem of forming a localized clogging area around the geotextile bags, and the method not only improves the efficiency of vacuum transfer in a pre-consolidation stage, but also improves the grouting effect in the later stage, effectively enhances the strength of soft soil and makes granular material piles and the surrounding soil form composite ground.

摘要: The present application relates to a precise lifting method and a lifting and reinforcing structure for a plant equipment foundation. The method includes the construction steps of: forming a curtain wall: drilling downwards at two sides of the plant equipment to form curtain holes and grouting the curtain holes, in which the grouting areas overlap each other to form two parallel curtain walls; forming a reinforcing body: drilling grouting holes inclining downwards, grouting the grouting holes to form the reinforcing body attached to a lower surface of a baseplate of the plant equipment foundation among a bottom of the baseplate and two curtain walls; and lifting: drilling lifting holes obliquely downwards to below the bottom of the reinforcing body and between two curtain walls; and conducting pressure grouting to the bottom of the lifting holes and then backward grouting upwards layer by layer.

摘要: A method for foundation consolidation combining vacuum preloading and geomembrane bag assembly loading, which comprises: digging a slurry pit, filling mud into the slurry pit and conducting vacuum preloading pumpdrainage for multiple times, laying the geomembrane bag assemblies above the soft slurry seam processed through vacuum preloading pumpdrainage inside the slurry pit to form a plurality of loading layers, and laying the geomembrane bag assemblies by piling geomembrane bags. In view of the engineering complexity and uneven settlement resulting from conventional vacuum preloading using slag loading, geomembrane bag for loading to overcome the adverse effects of slag loading. In the present invention, the drainage system and the geomembrane bag assemblies are laid out to fully leverage their perspective properties, so as to improve the transmission of vacuity in the whole soil mass, speed up the drainage rate, and increase the degree of consolidation.
