The invention relates to agricultural water conservancy equipment, in particular to agricultural hydrodynamic driven water spray equipment for a water conservancy project, and aims at achieving the technical purpose of providing the agricultural hydrodynamic driven water spray equipment for the water conservancy project adopting clean energy without needing frequent fuel supplying to improve the working efficiency. In order to achieving the above technical purpose, the invention provides the agricultural hydrodynamic driven water spray equipment for the water conservancy project, the equipmentcomprises an installation plate, supporting frames, a placement plate, a water tank, a first piston cylinder, a first piston block, a first push rod, a first sliding rail, a first sliding block, a first one-way valve and the like; the supporting frames are connected with the lower left and right sides of the installation plate, the placement plate is connected between the inner middles of the supporting frames, the water tank is placed on the placement plate, and the first piston cylinder is connected with the upper left side of the installation plate. By means of the equipment, the effect that the clean energy is adopted without needing frequent fuel supplying to improve the working efficiency is achieved.

The invention discloses a portable depth measuring device for hydraulic engineering. The depth measuring device comprises a main rod, wherein one end of the main rod is fixedly connected with a grip;the grip is sleeved with an anti-slip rubber pad; an outer rod is fixedly connected below the other end, opposite to the grip, of the main rod; an inner rod is arranged in a groove of the outer rod; and one side of the inner rod is fixedly connected with a plurality of first gears. The depth measuring device has the beneficial effects that: the depth measuring device is convenient to carry and usethrough arranging the grip, a detection block is arranged, the main rod is moved to a position above the water surface by means of the grip when in use, the inner rod moves downwards by rotating a rotary handle, a servo motor is turned on to drive a winding disc to rotate when the inner rod touches the bottom, a steel wire is put down until the detection block makes contact with the water surface, the servo motor is turned off, the inner rod leaves the water bottom by means of the grip, the water depth can be detected by detecting the distance between the detection block and the bottom part of the inner rod through using a scaleplate, and the depth measuring device is more convenient to use and carry by adopting the design.

The invention relates to the field of water conservancy projects and discloses a treatment method for a base of a high plasticity index soft soil foundation. The treatment method comprises the following steps: S1, cleaning and leveling the foundation: cleaning and leveling an operating site and preparing a drainage system; S2, carrying out pile driving construction on the ground to form a plurality of sand piles on the ground; S3, detecting qualities of the sand piles; S4, constructing stirring piles on the sand piles, wherein one stirring pile is formed in each sand pile; and S5, detecting qualities of the stirring piles. The method of adopting the sand piles and the stirring piles on the high plasticity index soft soil foundation can solve the problem of coordination of bearing capacityof the foundation of a hydraulic structure and settlement deformation effectively, so that a hidden danger that a centralized water leakage channel under a bottom plate is formed as a basic bottom plate of the hydraulic structure is avoided.

The invention discloses a water surface piling device for a municipal water conservancy project, which comprises a bottom plate, a clamping mechanism is arranged in the bottom plate, a support is fixedly connected to the top of the bottom plate, and supporting rods are fixedly connected to the front end and the rear end of an inner cavity of the support correspondingly; guide blocks are movably connected to the top and the bottom of the surface of the supporting rod, the right sides of the guide blocks extend out of the support and are fixedly connected with a box body, a hydraulic cylinder is fixedly connected to the top of an inner cavity of the box body, a piling block is fixedly connected to the bottom of the hydraulic cylinder, and a supporting plate is movably connected to the bottom of the piling block; a fixing mechanism is arranged in the supporting plate, the bottom of the supporting plate is movably connected with a pile driving column body, and the bottom end of the pile driving column body extends to the outside of the box body. The water surface piling device can be fixed according to the size of a pile driving column, and deviation is avoided during pile driving, so that the working efficiency is improved, and use by people is facilitated.

The invention relates to the technical field of cleaning devices, and discloses an automatic cleaning machine and method for hydraulic engineering. A rotating motor drives a pulley to rotate through amovable pipe, and the pulley rotates to drive the device to move; through the arrangement of a motor, a cleaning block can clean a flashboard in the up-down movement process; and through the arrangement of a first spring, the cleaning block can swing in the up-down movement process, so that the cleaning efficiency of the cleaning block is improved. According to the automatic cleaning machine andmethod for hydraulic engineering, after the motor is started, a rotary disc rotates, then a rotary rod drags a connecting rope, the connecting rope moves a tensile connecting column upwards, a secondspring is extruded by a balance block at the same time, the connecting rope does not drag the connecting column any more after the output end of the motor is controlled to rotate reversely, and the second spring is sprung downwards, so that the connecting column drives the cleaning block to clean the flashboard in the up-down movement process; and meanwhile, the balance of the connecting column inthe movement process is guaranteed through the balance block, so that the flashboard can be cleaned stably by the device.
