A. C.G.S construction method capable of seismic retrofit and quality control is provided. The method includes steps of inserted an injection pipe in the ground, the injection pipe provided for injecting a grout into the ground; injecting the grout into the ground through the inserted injection pipe, the grout being injected in predetermined quantities per unit time under an injection pressure that is a predetermined static pressure; measuring a discharge pressure of the injected grout; adjusting, according to the change in measurement value of the measured discharge pressure, at least one or more among the injection pressure of the grout in the injecting stage, and the unit time per which predetermined quantities of the grout are injected; and changing the depth at which the injection pipe is inserted in the ground after the injection of the grout is completed.

An axial reinforcement system is disclosed that provides a shell (i.e., a form or jacket) that protects a weight-bearing member (e.g., a cement column) from a corrosive environment and which also substantially increases the structural capacity of the weight-bearing member. The shell is integrated with “positioners” and reinforcing elements, the combination of which offers several advantages over conventional shells. The positioner is attached directly to the shell and the positioner is, in turn, secured to a reinforcing element, which can be a reinforced steel, such as rebar, or a carbon fiber reinforced polymer material. The axial reinforcement system has been found to substantially increase the structural rigidity of the weight-bearing member, while at the same time protecting the weight-bearing member from corrosion and is also simple to install.

A foundation system for the implementation of thermosolar and photovoltaic plants that comprises a component (1) made from reinforced or prestressed prefabricated concrete constituted by a lower slab (2), a longitudinal central rib (3) in the top part and comprising a pillar (4) that emerges from the top part of the central rib. A method for implementing said foundation that comprises the phases: prefabrication (13) of a panel (1) of reinforced or prestressed concrete, the laying-out (14) of a bed of sand (12) over a surface, placing (15) the component (1) on said bed of sand (12), filling (16) with granular material (11) over the lower slab (2) of the panel (1) up to the upper reference mark on the pillar (4), placing (17) a supporting structure (9) inside the pillar (4), wedging (18) of the supporting structure, and filling (19) of the existing hollow using mortar.

A cutting tool adapter for creating an underpinning structure and method of creating the underpinning structure are provided. In some examples, the cutting tool adapter may connect a cutting tool to a working machine arm to enable the cutting tool to cut and dislodge soil below an existing foundation or structure. As the soil is cut and dislodged, it is mechanically mixed with an additive, such as a cementitious material, via the cutting tool. The mixed soil and additive may then harden in the area below the existing structure or foundation to create an underpinning structure to provide additional support for the existing structure or foundation.

A mortar collar positionable to contain and protect a flowable sealant during curing thereof.

The present disclosure discloses a combined offshore wind power foundation with duct piles and a bucket, which comprises duct piles and a bucket foundation; the bucket foundation includes a steel bucket skirt, a bucket top cover, main beams, ring beam and a transition section. A top of the steel bucket skirt and the bucket top cover are integrally formed into a semi-closed structure. The bucket top cover is provided thereon with main beams uniformly arranged in a circumferential direction. The ring beam are arranged at an edge of the bucket top cover. Each duct pile includes a duct, a steel pile, duct supports and high-strength mortar, each main beam is provided at its outer side end with one of corresponding. The duct support is connected with the main beam and the ring beam, and integrated with the bucket top cover, the main beams and the ring beam.
