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： A grouting pipe with a vibration function includes: a grouting pipe body provided with a hydraulic control structure, a vibration structure and a grouting hole control structure; wherein the vibration structure is rotatably arranged inside the grouting pipe body, and the hydraulic control structure is provided outside the grouting pipe body; the grouting hole control structure is provided on an internal wall of the grouting pipe body, and the hydraulic control structure is connected to the grouting hole control structure through a first hydraulic pipe. The grouting pipe solves the technical problems that conventional grouting pipes may be blocked by sandy soil during a press-in process, and it is difficult for the slurry to diffuse.

摘要： An assembly and method of simultaneously spin drilling and pressure grouting a helical anchor into the ground vertically, horizontally or at an inclined angle create a continuous grouting configuration inside and outside the helical anchor for its entire depth in the ground. The helical anchor is configured to be partially or completely removed as desired and can be provided at its upper end with a tensioning element to post tension a cementitious foundation structure. A unique spin drilling and grouting assembly continuously provides grout under pressure to the interior of the helical anchor during its spin drilling into the ground. In one embodiment, the pressure grouted helical anchor is used with an upwardly extending tensioning element to reinforce cementitious foundation caps or other concrete support foundations.

摘要： The present invention relates to a foundation structure vertically installed on the ground, and comprising: an upper support layer 10 formed on the ground in the vertical direction; and a lower support layer 20 formed so as to extend downward from the upper support layer 10 and such that the width thereof is less than that of the upper support layer 10. The disclosed upper support layer 10 and the lower support layer 20 are structures formed from soil solidified by means of feeding and mixing an earth and soil-solidifying agent therein, and therefore are efficient and prevent overload due to boring equipment.

摘要： An apparatus for constructing a subsurface containment barrier under a waste site disposed in soil is provided. The apparatus uses a reciprocating cutting and barrier forming device which forms a continuous elongate panel through the soil having a defined width. The reciprocating cutting and barrier forming device has multiple jets which eject a high pressure slurry mixture through an arcuate path or transversely across the panel being formed. A horizontal barrier can be formed by overlapping a plurality of such panels. The cutting device and barrier forming device is pulled through the soil by two substantially parallel pulling pipes which are directionally drilled under the waste site. A tractor or other pulling device is attached to the pulling pipes at one end and the cutting and barrier forming device is attached at the other. The tractor pulls the cutting and barrier forming device through the soil under the waste site without intersecting the waste site. A trailing pipe, attached to the cutting and barrier forming device, travels behind one of the pulling pipes. In the formation of an adjacent panel the trailing pipe becomes one of the next pulling pipes. This assures the formation of a continuous barrier.
