This utility model relates to the field of construction engineering technology and discloses a lifting device for construction engineering, including a base. The top of the base has a clearance groove, and a lifting bucket is mounted on the top of the clearance groove. A support frame is fixedly connected to the bottom of the lifting bucket, and a cylinder is fixedly connected inside the support frame. A push rod is fixedly connected to the output end of the cylinder. This utility model has the following advantages and effects: When the lifting bucket rises, the first and second lifting plates increase stability. Anti-slip holes slide on the outer surface of the guide rod. The first lifting plate supports the top of the lifting bucket, and the second lifting plate supports the bottom of the lifting bucket, making lifting more stable. When it rises to a certain height, the cylinder is activated to drive the push rod upward, and the push rod pushes the placement frame out of the lifting bucket, facilitating the discharge of the placement frame and thus enabling the rapid removal of building materials from the lifting bucket, improving lifting efficiency.

The invention relates to the technical field of slope engineering construction, in particular to a construction method for preventing collapse in a slope construction process, which comprises the following steps of: dividing at least two unit slope sections in a preset slope excavation area along the direction from the slope top to the slope bottom; when the first unit slope section is constructed, the first slope surface is exposed; a supporting structure is arranged at the bottom of the first slope surface; based on the supporting structure, a protection structure is arranged along the outer surface of the first slope surface; and other unit slope sections are constructed according to the protection mode of the first unit slope section. The construction of the slope is split from the slope top to the slope bottom according to the unit slope section, so that protection is carried out while excavation construction is carried out on the unit slope section, the anti-collapse capacity of the unit slope section is improved, and therefore the construction method can be applied to slope construction in rainy seasons or areas where rainy days are frequent; the construction reliability of the side slope under severe conditions is improved; and the construction risk is reduced.

The invention discloses a modular assembly type concrete channel system suitable for abrupt slope mountainous regions, and relates to the technical field of hydraulic engineering and slope treatment, in particular to a modular assembly type concrete channel system suitable for abrupt slope mountainous regions, which comprises an anti-slide pile foundation and a channel main body module arranged on the anti-slide pile foundation. The channel body module is of a U-shaped structure, a male opening is formed in the front end of the channel body module, a female opening is formed in the rear end of the channel body module, and a rubber waterstop is embedded in the inner side of the female opening to achieve sealing connection. The multiple channel main body modules are in butt joint through male and female openings, and prestressed steel cables penetrate through the channel main body modules to enhance integrity. The upper end of the module is lapped with a cover plate, and the inner side wall is provided with drainage holes. The system adopts a modular assembly design, is simple and convenient to construct, can effectively adapt to abrupt slope terrains, and improves the anti-sliding stability and the anti-seepage performance.

This utility model relates to the field of ecological slope protection technology, and discloses an ecological slope protection structure for waterway dredging. It includes a slope surface, a slope protection structure on the top surface of the slope surface for stabilizing the slope, a plant support frame mechanism on the top surface of the slope protection structure for supporting longer plants, and a plant box assembly on the top surface of the slope protection structure for providing plant growth space. The slope protection structure includes a concrete layer on the top surface of the slope surface, with multiple drainage channels inside the concrete layer, and anchor bolt assemblies on the top surface of the drainage channels. In this utility model, by laying a concrete layer on the surface of the slope, the retaining wall enhances the slope stability, while the slope protection bag and plant box assembly provide a stable growth space for plants, fix the soil, and prevent soil erosion.

The utility model relates to the technical field of wind lamp, specifically disclose an easily detachable ceramic wind lamp, including base and lamp shade, the base and lamp shade are detachably connected through the clamping mechanism, the clamping mechanism includes the boss fixedly connected in the base inside, the boss and the inner wall of base form the annular groove matched with lamp shade, the inside of base and boss is provided with the cavity, the inside rotation is connected with the shaft of cavity, the outer wall fixedly connected with the turntable of shaft, the outer wall rotation is connected with two connecting rods of turntable through connecting axle, the inside of cavity front and back two end surfaces are fixedly connected with two limit rods, through the clamping mechanism cooperation L shape groove design, user only needs single time to push the push rod to realize the unlocking or locking of lamp shade. Spring automatic reset function simplifies the installation step, makes lamp shade dismounting and installation process not to need the tool, has improved the efficiency of replacing candle and cleaning lamp shade significantly, especially suitable for frequently used scene.
