Construction Method of Fast-setting Polymer Grouting for Rapid Control of Slope Erosion and Landslide
A construction method of fast-setting polymer grouting for rapid control of slope erosion and landslide. This solution includes a landslide control method and a slope erosion control method: sorting out an operation platform; drilling and grouting of polymer high-pressure jet grouting piles on the diseased slope; drilling a row of grouting water interception holes densely on the rear edge of the diseased slope; drilling, on the operation platform, a plurality of anchor holes on the diseased slope; inserting a ground anchor into each anchor hole and performing polymer grouting to form a polymer anchorage body; laying a steel wire gauze on the surface of the diseased slope, and connecting and fixing the steel wire gauze with the tail end of each ground anchor; spraying a two-component expandable polymer grouting material onto the steel wire gauze to form a polymer anti-scour layer; drilling a plurality of planting holes on the diseased slope with a backpack drill through meshes of the steel wire gauze; and filling each planting hole with grass seed mixed nutrient soil. The present invention has the advantages of short construction period, ecological and environmental protection, convenient construction, high strength and strong scour resistance.
Semi-finished part for a foundation of a tower construction, semi-finished part foundation segment, foundation, method for producing a semi-finished part and method for producing a foundation
A semi-finished part for a foundation of a tower construction, in particular of a wind turbine tower, comprising at least two semi-finished part foundation segments, which each have an outer delimitation element and a reinforcement, which is connected to the outer delimitation element and comprises struts protruding from the outer delimitation element, wherein: the outer delimitation elements of the semi-finished part foundation segments form an outer edge, which delimits an interior to be later filled curable casting material; and the reinforcements of the semi-finished part foundation segments extend from the outer edge into the interior.
System and method for installing a membrane-lined buried wall
A system and method for installing a membrane-lined wall for levee reinforcement or leak prevention. The installation system may comprise a sled positioned above the trench having a length, and may comprise a frame and support members, and a weight suspension system mounted on the frame to lower an elongated weight into the trench. The liner installation sled may also include a liner roller rotatably mounted on the frame, the liner roller adapted to hold a roll of a liner above the surface on a first side of the trench when the liner installation sled is in an installation position relative to the trench, wherein a longitudinal axis of the roll of liner can be aligned with the length of the trench. The elongated weight is usable to force the liner into the trench.
METHOD AND DEVICE FOR PRODUCING CONCRETE PILE
A manufacturing method of a concrete pile is shown. The method includes the following, that is, pouring concrete in the pile molding space, reducing the pile molding space to compress and mold the concrete, draining water drained from the concrete by compression and molding outside of the formwork from the drainage hole, and holding the concrete a predetermined amount of time to harden the concrete. The formwork includes an outer formwork that molds an outer wall surface of the concrete pile, an inner formwork that molds an inner wall surface of a hollow space of the concrete pile, and a pair of end formwork that mold upper and lower end surfaces of the concrete pile. The drainage hole is a gap between adjacent components when the mold is tightened, and the gap is configured to be capable of being opened larger during cleaning than when the mold is tightened.
Building foundation and soil stabilization method and system
System and means soil stabilization and moisture control for building foundations including methods and systems for stabilization moisture in a site for building foundation by applying soil moisture stabilization material in various forms, a preferred stabilization material being a mixture of aluninosilicate Pozzolan mineral and granular material such as sand.
Load Transfer System
This is a new type of pile foundation for support of structures. It uses a new method of forming concrete around the steel rebar prior to installing the rebar. Concrete is molded in an undulating fashion to improve load transfer to the adjacent hole backfill. The backfill is densified in place and grouted to maintain the dense configuration. The grouting is injected into an unlined hole. If temporary casing is used during drilling, it is removed prior to grouting. The basic premises are that grouting the hole backfill to the surrounding soil provides a better load transfer at that interface. And, beyond a few inches past the steel rebar, grouted dense sand and gravel are adequate for the load at that point. Timing of the grouting is more flexible than typical ready-mix concrete delivery systems. This method also allows for real time testing of the pile capacity.
SEAWALL CONSTRUCTION USING CONCRETE FORMS
A method for constructing a seawall section includes coupling an end of a substantially-waterproof barrier member to a footing. A concrete form is mounted to the footing such that a top end of the form is higher than an exposed upper surface of the footing. The concrete form defines at least part of a fill volume. Another end of the barrier member is coupled to the concrete form such that the barrier member extends over a side of the concrete form opposite the fill volume. Concrete is then poured into the fill volume and cured to form the seawall section. Prior to the curing, a body of water at the footing may be higher than the upper surface of the footing. However, the barrier member prevents water from entering the fill volume through the concrete form.
Method and Device for Pre-Casting Conduit Holes in Building Foundations
A method of constructing multiple conduits in building foundations that eliminates the process of core drilling after the foundation has been poured and set. This method creates optional openings for possible future connections. The process uses removable conduit molds installed before the foundation is poured. Once the foundation has set, conduit molds are removed to explose conduits in the foundation as needed.
Lake restoration systems and processes
Systems and methods of restoring a lake including dredging, island creation, water treatment, real estate development, computer modeling of environmental conditions, wave height reduction, sediment removal and encapsulation, bathymetry contouring, littoral zone restoration, plant restoration, and/or fish restoration.
METHOD OF FORMING A WIND TURBINE FOUNDATION
A method of forming a foundation (26) of a wind turbine (10) including a tower (12) having a base tower section (24), comprising: mounting a levelling apparatus (56) to an anchor cage (30), the anchor cage (30) including a plurality of anchor bolts (36) extending between an upper flange (34) and a lower flange (38), the levelling apparatus (56) being arranged between the upper and the lower flanges (34, 38); arranging the anchor cage (30) in an excavation pit (94); directing a cementitious material into the excavation pit (94) so that the upper flange (34) becomes at least partially embedded within the first cementitious material; allowing the cementitious material to cure to form a rigid body (28, 90); actuating the levelling apparatus (56) to raise the upper flange (34) from the rigid body (28, 90) into a levelled position; directing a grout material (32) into a space beneath the raised upper flange (34); and allowing the grout material (32) to cure to form a support layer. The invention extends to an anchor cage arrangement and a system for forming a wind turbine foundation.
