A membrane-lined wall for levee reinforcement or leak prevention, prevention of water migration, and pollution control of impoundments. The membrane-lined wall generally includes a cementitious or concrete wall formed within an excavated trench. The concrete may be internally reinforced, and the wall may also comprise a double-layer of impermeable geomembrane liner that forms a barrier between the concrete and the sides and bottom of the trench. The membrane or liner reduces water migration, prevents levee leakage, and prevents the escape of contaminants in impoundments.

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.

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.

The present invention relates to a self-supporting, prefabricated, folding form structure or mechanism to be used in the construction industry. It is based on various types of geometries, providing enhanced strength and stability for the concrete and other building material casting process. The object of this invention is a foldable, prefabricated, self-supporting form and does not require a structure. It is configured in a variety of geometric shapes and is based on structural elements that have internal casting chambers or ducts interconnected between each other through perforated holes. This is done by means of internal assembly channels or cavities forming casting chambers. The casting chambers are interconnected with each other, through holes drilled in the structural elements. This way the form features an assembly between its walls through cracks or assembly cuts, creating an architecture of superior engineering that provides higher resistance and stability.

A method for forming a trench and a membrane-lined wall in the trench for levee reinforcement or leak prevention, prevention of water migration, and pollution control of impoundments. The membrane-lined wall generally includes a cementitious or concrete wall formed within an excavated trench. The concrete may be internally reinforced, and the wall may also comprise a double-layer of impermeable geomembrane liner that forms a barrier between the concrete and the sides and bottom of the trench. The membrane or liner reduces water migration, prevents levee leakage, and prevents the escape of contaminants in impoundments.

The present invention relates generally to an injectable tie back cover for waterproofing, apparatus, and a method of using same. The invention encompasses a substantially domed shaped structure having at least one surface along the domed shaped structure, and having an edge flanged surface which is placed over a tieback head, and where the injectable tieback cover is used as a waterproofing apparatus. A supplemental injectable tubing can also be provided around the outside of the substantially domed shaped structure, which injectable tubing can be injected with a secondary waterproofing material to provide additional waterproofing to the area around the injectable tie back cover facing the concrete or shotcrete. The domed shaped structure can also have at least one dome channel to accommodate at least one injectable tieback cover tubing. The invention also provides a method of using the inventive injectable tie back cover for waterproofing structures.

A track-type shotcrete integrated system includes: a proportioner working bin, a storage bin, a power bin, and load-bearing legs, wherein bottom sections of the load-bearing legs are equipped with a track chassis for moving, and the track chassis is electrically connected to a track controller; the storage bin contains a storage tank I and a storage tank II for storing different raw materials; a feed pump I is installed on a top of the storage tank I, and a feed pump II is installed on a top of the storage tank II; inlet pipes of the feed pump I and the feed pump II insert into the storage tank I and storage tank II respectively, and outlet pipes of the feed pump I and the feed pump II are connected to a feed pipe I and a feed pipe II respectively.
