The invention relates to a foundation engineering machine and a method for producing a trench in the ground with a foundation engineering machine having a substantially vertical mast, a diaphragm wall apparatus which is displaceably supported in the longitudinal direction of the mast for producing a trench in the ground, and a bar-shaped holding means, at the lower end of which the diaphragm wall apparatus is mounted and with which the diaphragm wall apparatus is linearly displaceable along the mast. According to the invention provision is made in that on the mast an upper first clamping sledge with a first clamping means for releasably clamping the bar-shaped holding means and a lower second clamping sledge with a second clamping means for releasably clamping the bar-shaped holding means are movably supported and the first clamping sledge and the second clamping sledge are movable relative to each other and in that the lower second clamping sledge is provided with a connecting means for mounting an additional lifting device which is arranged on the ground and with which a force can be applied in the longitudinal direction onto the second sledge.

To provide a CLT structure in which an anchor member does not interfere with a reinforcement member. A CLT structure includes a strip footing having a reinforcing bar extending in a longitudinal direction, a wall panel which is a panel material obtained by laminating and bonding sawn boards and in which a slit extending along the longitudinal direction is formed in a lower end surface, joint plates each partly embedded in the strip footing and having a joint board section of a flat plate shape at least partly projecting upward from an upper surface of the strip footing, and drift pins connecting the joint board sections and the wall panel in an inserted state where the joint board sections projecting from the upper surface of the strip footing are inserted into the slit of the wall panel. The joint plate has the joint board section, a flange section embedded in the strip footing and extending in a direction crossing the perpendicular direction from the joint board section, and an anchor bolt embedded in the strip footing and extending downward from the flange section.

The bridge construction system and method according to the present invention provides a lightweight, efficient, economical, long-lasting, and easily implemented composite steel structure that can be filled with concrete in place for the construction of pedestrian and smaller road bridges, specifically those found in rural areas. The bridge construction system of the present invention is unique in that it is a steel-frame reinforced composite bridge with decking and rebar caging that provides a permanent, non-removable form for poured-in-place concrete. The composite nature of the bridge allows for installation of the bridge to take place in one day, while the entire process from site preparation such as grading and excavation to cleanup takes a week or less. The quick installation of the bridge is designed to have a minimally invasive impact on the surrounding environment.

Improved equipment bases and methods for making and using same are disclosed herein. The equipment base can include a first coated substrate including a first part having a first thickness sized to provide the load-bearing support for the equipment, a first elastomer coating the first part, a second coated substrate positioned adjacent to the first coated substrate, the second coated substrate including a second part having a second thickness sized to provide the load-bearing support for the equipment, and a second elastomer coating the second part. A first seam can be formed between the first and second coated substrates to allow for moisture to pass between the first and second coated substrates so that moisture is allowed to seep away from the bottom of the equipment.

A support stand for supporting a volumetric modular unit above the ground is disclosed. The support stand includes a top portion with a top surface for contacting and supporting an underside of the modular unit above the ground. A bottom portion with a bottom surface supports the top portion at an elevation above the ground against the underside of the modular unit. An elevating portion has a top side connected to the top portion, a bottom side connected to the bottom portion, and an elevating span between the top side and the bottom side. A pad is connected to the bottom portion. The pad has a bottom surface for contacting and supporting the bottom portion against the ground, an inner pad perimeter and an outer pad perimeter. The top surface is parallel with the bottom surface. The underside and weight of the modular unit is supported on the top surface.

A threshold system with an insulated thermal break device configured to provide a thermal break for insulating a door opening and related methods is provided.

A height-adjusting apparatus for a mobile foundation includes a rod with a threaded portion and a threaded plate, which is retained in an adjustable manner on the threaded portion and has a supporting surface. The height-adjusting apparatus also includes a tube, which has a cavity. The tube comprises at least one wall aperture on an outer side, as a result of which the rod projects into the cavity. Additionally, the height-adjusting apparatus is configured such that the rod can be rotated relative to the tube at least in part about an axis parallel to the longitudinal axis of the tube.
