摘要： A system for assisting in preventing the leakage of liquid from an outdoor work-site and allowing vehicle ingress onto and egress off of the work-site includes a plurality of berm members configured to be positioned at least partially around the perimeter of a support surface and extend upwardly relative thereto. At least one berm member includes a ramp portion having upwardly angled faces disposed at least partially along the front and rear edges of the berm member to allow vehicles to move up, over and down the ramp portion when entering and leaving the support surface.

摘要： An undershot gate system controls flow of liquid through an open channel or pipe. The system includes a gate leaf adapted to be raised and lowered by a control means to allow flow of liquid along the open channel or pipe. The gate leaf has a flow diverter at an end of the gate leaf to guide liquid under the gate leaf and through an opening when the gate leaf is in an open position.

摘要： The invention discloses an overshot control gate for use with trapezoidal irrigation channels. A gate has a rigid rectangular section adapted to, in use, be pivotally mounted to a base of a trapezoidal irrigation channel. A pair of triangular sections are pivotally mounted on opposite sides of the rigid rectangular section. Each of the triangular sections are divided into first and second triangular sections with a common apex at the base of the trapezoidal irrigation channel. Each of the first triangular sections are rigid and adapted to, in use, be pivotally mounted to opposite side walls of the trapezoidal irrigation channel. Each of the second triangular sections including the pivotal mounting on opposite sides of the rigid rectangular section are formed of a flexible material. Also disclosed is a pipe flow meter and a duckbill valve.

摘要： A discharge control system for a reservoir having a pressure-communicating valve in a valve chamber with the inlet of the pressure-communicating valve connected the reservoir outlet aperture and the outlet of the pressure-communicating valve connected to a discharge aperture in the containment structure for the valve chamber. An auxiliary reservoir outlet aperture enables water to flow from the reservoir into the valve chamber, submerging the pressure-communicating valve. Water flows from the valve chamber through a valve chamber outlet aperture that is substantially the same as the auxiliary reservoir outlet aperture and is located at substantially the same height as the center of the reservoir outlet aperture. One or more supplemental auxiliary reservoir outlet apertures are located at incrementally greater heights in the containment wall for said reservoir to assure that water will enter and leave the valve chamber at the same rate under all conditions.

摘要： A hydraulically actuated locking element with two locking bolts axially displaceable on an axis. A carrying structure is provided with two, slidingly guided hydraulic cylinders, two cylinder bottoms, which act as locking bolts and are designed as force-transmitting cylinder bottom. A centrally fastened, common piston rod of the hydraulic cylinders is provided with a stationary piston at each piston rod end. A centrally rigidly connected piston rod fastening is arranged in the carrying structure and between the two, sliding hydraulic cylinders. The piston rod fastening and the piston rod are provided with holes for guiding hydraulic oil.

摘要： A water-level control device is provided for controlling water levels between a high-tide level and a low-tide level. The water-level control device comprises a tiltable pipe connected to a drain pipe by a flexible joint. Tilting of the pipe allows flow of water from a high-tide point to a low-tide point. Water is pumped into a pond continuously, and the variable-height weir cyclically varies the outflow to simulate a tidal cycle.

摘要： In a situation where animals, such as beavers, attempt to flood lands by blocking culverts or constructing dams across waterways, a device is used to maintain a constant flow of water through the dam or culvert. An elongated pipe or culvert with a downwardly directed opening distant from the culvert or dam is used. On the end of the pipe closest to the culvert is a gate which prevents animals and debris from passing through but allows for the smaller elongated pipe to communicate with the culvert. The beaver instinctively attempts to dam the gate area rather than dam the underwater opening of the elongated pipe, and thus is unsuccessful in stopping the flow of water.
摘要翻译： 在诸如海狸等动物试图通过拦截涵洞或在水道上建造水坝来试图淹没土地的情况下，使用一种装置来保持恒定的水流通过大坝或涵洞。 使用具有远离涵洞或坝的向下指向的开口的细长管或涵洞。 在最靠近涵洞的管道的末端是防止动物和碎片通过但允许较小的细长管道与涵洞连通的门。 海狸本能地试图阻挡闸门区而不是阻挡细长管的水下开口，因此不能阻止水的流动。

摘要： A filter assembly for allowing groundwater to flow through a hole in a seawall from a landward side of the seawall to a seaward side of the seawall includes a housing with a flange and a perforated shell. The filter assembly also includes a filter cartridge configured to be removably positioned inside the shell and a face plate positioned over the opening and removably connected to the seaward side of the flange thereby securing the filter cartridge inside the shell. The filter assembly also includes a valve member that is operable in an open state and in a closed state. The filter assembly also includes a deflection device connected to a seaward side of the face plate over the valve member. The deflection device is configured to prevent interference of the valve member.
