The present disclosure provides a device for preventing frost heaving and thawing settlement. The device includes a positioning cylinder, an upper cover, an anti-thawing settlement rod configured to prevent the thawing settlement, and an anti-frost heaving rod configured to prevent the frost heaving. The upper cover is sealingly assembled on a top of the positioning cylinder. A bottom of the positioning cylinder is provided with the anti-frost heaving rod. An upper portion of the positioning cylinder is provided with the anti-thawing settlement rod. The anti-frost heaving rod is provided upwards, and a bottom of the anti-frost heaving rod is rotatably provided on a mounting base of the anti-frost heaving rod through a first connecting screw rod. The anti-thawing settlement rod is provided downwards, and a top of the anti-thawing settlement rod is rotatably provided on a mounting base of the anti-thawing settlement rod through a second connecting screw rod.

An earth retention levee system is disclosed which is constructed from spaced apart facing parallel walls of interlocking sheet piles (1, 2) said sheet piles having outside faces (5) and inside faces (4) formed with gridspines (10) along a longitudinal extent thereof, said gridspines (10) being connected to adjacent edges of geogrids (20) which link said parallel walls and stabilise fill (21) disposed therebetween.

A cementitious composite for in-situ hydration includes a structure layer having a first side and an opposing second side, a cementitious material disposed within the structure layer, a sealing layer disposed along and coupled to the first side of the structure layer, and a containment layer disposed along the opposing second side of the structure layer. The structure layer has an intersection at the sealing layer and the containment layer that is at least partially fiberless. The cementitious material includes a plurality of cementitious particles. The containment layer is configured to prevent the plurality of cementitious particles from migrating out of the structure layer.

Provided are a strip-type reinforcing material and a reinforcing material assembly having the same. The strip-type reinforcing material includes: strip bases extending in one direction and made of a flexible material; and resistance means protruding from respective upper and lower parts of the strip bases. Multiple resistance means are provided along the strip bases. The resistance means includes: a first resistance part protruding from the upper parts of the strip bases and having an opening being open in a direction parallel to a longitudinal direction of the strip bases; and a second resistance part protruding from the lower parts of the strip bases and having an opening being open in an opposite direction to the opening of the first resistance part.

A caisson block construction method, including: manufacturing a plurality of bottom caisson blocks having a plurality of first unit compartments disposed consecutively in a horizontal direction; manufacturing a plurality of upper caisson blocks having a plurality of second unit compartments; forming a bottom caisson block structure by installing the plurality of bottom caisson blocks side by side in the horizontal direction; installing the plurality of upper caisson blocks above the W installed bottom caisson blocks; filling with rubble the second unit compartment of the upper caisson block positioned above the first unit compartment for rubble and exposed upward; inserting a vertical reinforcing bar module after the upper caisson blocks are installed; and forming a vertical concrete column for joining by casting concrete into the upper part of the second unit compartment in which the vertical reinforcing bar module is inserted.

A modular foundation design for supporting a wind turbine or telecommunication tower, comprised of pre-cast concrete modules offering advantages of off-site manufacture and ease of transportation, but which deign is simple to construct. A base slab is provided comprised of sub-modules/base members arranged together in juxtaposed position which together provide a horizontal surface on which pre-cast pipe members may be stacked in end-to-end position to form a pedestal. Anchor rods extend through the pipe members into screw retainers in the base members, which rods serve to not only post-tension the pipe members and secure them together, but further advantageously serve to retain the base members together thereby assisting in distributing forces and loads applied to one sub-module/base member over the entire base slab. Coupling means to further couple the base members together may be added to better retain the base members together and still further improve distribution of forces.

Disclosed is an inverted fastening mortise structure of building for resisting an earthquake, strong wind or tsunami and technical procedure thereof. The adopted inverted fastening mortise makes mortises ring lie in dividing space between ground ring beam of building and foundation ground and makes building press and composite suspended in patand. The inverted fastening mortise structure like a sleeping dragon eliminates earthquake, wind and tide, including longitudinal and transverse waves in the aspect of direction of earthquake waves, sectional wave, swing wave and crawling wave in the aspect of shape, the promotion of wind moment of combined wind and horizontally pushing of tsunami wave. The inverted fastening mortise structure eliminates the destroy to building in the process of displacement of building and foundation by control the disaster energy of the three disasters.

Systems and methods to provide pressed aggregate-filled cavities for improving ground stiffness and uniformity are disclosed. According to an aspect, a method includes using a mechanism to press into a ground surface in a substantially downward direction to create a concavity. The method also includes substantially or completely filling the concavity with unstabilized or chemically stabilized aggregate, soil, or sand. Further, the method includes using the mechanism to press the aggregate within the concavity to achieve a desired ground stiffness.
