A device and method for mud solidification based on electro-osmosis well points cooperating with well-points dewatering. The method includes the following steps: 1) preparation; 2) construction of well point pipe positioning frame beams; 3) assembly of a mobile trestle platform; 4) well point pipe arrangement; 5) well point/electro-osmosis dewatering; 6) filtrate treatment; 7) well point pipe dismantling; and 8) excavation and transportation of solidified drilling slag for utilization. According to the disclosure, well point pipes are adopted and used as an anode and a cathode of an electro-osmosis well, and on-site quick solidification of pile foundation mud is implemented through the electro-osmosis combined with light well-points dewatering; by the adoption of the well point pipe positioning frame beams, the problems that drilling slag in a sedimentation tank has a large water content and it is difficult to arrange and fix the well point pipes are well solved.

The Passive Tailings Compactor is a system of components for facilitating the continuous passive drainage and consolidation of fine-grained sediments in active and continuous deposition environments. The invention consists of a flotation device, an anchor mass, and a drainage conduit which acts as a tether between the flotation device and the anchor. The flotation device also serves to orient the drainage conduit horizontally. As water or sediment levels rise, the flotation device rotates, releasing drainage conduit wrapped around its axis. This allows the flotation device to move upwards, extending the drainage conduit passively. The flotation device uses asymmetrical fixed weights to resist lesser rotational forces. The drainage conduit serves to create a path of relatively high hydraulic conductivity, protected by a filter barrier, for the dissipation of pore pressures and consolidation of buried sediments. The anchor mass fixes the system in place.

Embodiments describe a method for moisturizing soil at an open construction site. The method includes determining a target soil moisture level for the soil at the open construction site; measuring a current soil moisture level of a location within the open construction site with a moisture sensor while the moisture control system is moving along a predetermined path across the site; storing the current soil moisture level of the location in memory; determining a target volume of water for achieving the target soil moisture level at the location based on the current soil moisture level at the location; calculating a target application rate to achieve the target soil moisture level at the location based on the target volume of water; and applying the target volume of water at the target application rate to the location when the system is positioned to dispense water at the location of the site.

The invention relates to a machine for putting a drain into place in ground, the machine comprising a drive tube presenting a longitudinal axis and having a bottom end; a movement device for moving the drive tube in a direction parallel to the longitudinal axis; a drain extending inside the drive tube and having a bottom end extending outside the drive tube; at least one anchor; a fastener device (70) for fastening the anchor to the drain; and a cutter member for cutting the drain (18) and arranged under the fastener device. The machine of the invention further comprises a cutter device (60) for cutting the anchor from a strip (54).

Bio-derived glycerides formed from a reaction between waste glycerol and biodegradable or bio-derived fatty acid esters such as crude biodiesel or soybean oil triglycerides are useful as dust suppressants, binders, and stabilizing agents.

The present invention discloses a system and method for constructing retaining wall structure and well point in granular soils under groundwater level. The system is configured to drain the excavated zone and stabilizes the soil slope wall especially in urban lands with granular soils and high groundwater level during construction process. The system is configured to enable installation of vertical beams and polyethylene grooved drainage pipes wrapped by geotextile for drainage in the boundaries of the desired land by using a hammering casing pipe system. The hammering casing pipe system comprises a casing to receive the vertical beam and the drainage pipe, a mandrel for inserting the casing to the target location without removal of soil in the casing, a hammer element for hammering the mandrel into the target location, and a steel shaft or an impact transmission shaft configured to transfer impact from the hammer element to the mandrel.
