The utility model relates to a stepped parapet wall with a buffering green plant planting structure, and relates to the field of parapet walls. The roof comprises a roof plate and a parapet wall arranged on the upper end face of the roof plate, a waterproof layer is laid on the upper end face of the roof plate, a step buffering table is arranged between the waterproof layer and the parapet wall, a triangular net rack is installed on the outer side face of the step buffering table, and the bottom face of the triangular net rack is attached to the waterproof layer. And the vertical edge of the triangular net rack is attached and fixed to the step buffer table. According to the roof structure, the step buffer table is arranged between the traditional roof plate and the parapet wall, the impact of rainwater is reduced through the step buffer table, through the synergistic effect of all the components, the good buffer performance is achieved, the waterproof layer can be effectively protected, and damage of rainwater to the roof structure is reduced. And meanwhile, a water source on the roof can be better discharged and utilized through the stepped buffer table.

This utility model relates to a riverbank structure that integrates pollution mitigation and ecological greening, belonging to the field of riverbank structure technology. It includes a polluted soil layer along the riverbank and a riverbed. A barrier mechanism is provided on the right side of the polluted soil layer. The barrier mechanism includes a first clay impermeable layer, a first ecological gabion retaining wall, a soil layer, a second clay impermeable layer, two second ecological gabion retaining walls, and ecological greenery. This riverbank structure, integrating pollution mitigation and ecological greening, isolates the polluted soil layer from the riverbed by setting the first clay impermeable layer and the first ecological gabion retaining wall on the right side of the polluted soil layer, preventing liquid pollutants from flowing into the riverbed. When the first clay impermeable layer is damaged, the second clay impermeable layer can provide further protection. The two second ecological gabion retaining walls enhance the stability of the riverbank structure and reduce the risk of breaches.

This utility model discloses a refrigeration device based on modular design, including an internal evaporator and an external integrated outdoor unit. The integrated outdoor unit comprises a frame body, which includes a bottom frame, side panels, a top panel, and side-mounted air-cooling equipment. The side panels have air intake grilles. The condenser and air-cooling equipment are located at opposite ends of the bottom frame, with multiple compressors positioned between them. A transverse main pipeline is located on the upper surface of the bottom frame, with its connection point connected to the compressor's air intake. The sides of the integrated outdoor unit have refrigerant outlet pipes, refrigerant inlet pipes, hot water pipes, and cold water pipes, which are connected to the condenser, main pipeline, etc., respectively. This utility model, through modular design, integrates multiple components, solving the problems of complex piping and inconvenient maintenance in existing workshop refrigeration devices. It improves the environment, facilitates maintenance, and achieves efficient energy utilization.

The utility model relates to the technical field of slope retaining, and discloses an assembly type recoverable retaining wall device which comprises a positioning assembly, a retaining assembly, a greening assembly and a closing assembly, and the positioning assembly is made of reinforced concrete; the positioning assembly is placed on a concrete cushion layer; the positioning assembly comprises a wall toe and a clamping groove, and the clamping groove is rectangular; according to the retaining wall, the positioning assemblies, the wall toes, the clamping grooves, the soil retaining assemblies and the clamping pipes are arranged, the anti-sliding capacity of the foundation is remarkably enhanced through the design of the wall toes of the positioning assemblies, the clamping grooves and the clamping pipes of the soil retaining assemblies are fixedly connected in an embedded mode to form an overall stress system, the anti-overturning performance of the retaining wall is greatly improved, and through the stacked inserting design of the multiple layers of soil retaining assemblies, loads are transmitted through self weight; the structure stress distribution is optimized, the number of layers (such as 3-8 layers) of the soil retaining assemblies can be dynamically adjusted according to the height of the slope, the landform requirements of different engineering scenes are flexibly met, and the modularization adaptability is effectively improved.

The utility model belongs to municipal engineering technical field, specifically is a kind of sponge city infiltration and drainage device, the middle part of the infiltration and drainage pipe is fixedly connected with drainage net pipe;The end of drainage net pipe is fixedly connected with water storage pool;The end of drainage net pipe close to water storage pool is fixedly connected with fixed frame;The middle part of fixed frame is fixedly connected with elastic rope;The middle part of elastic rope is slidably connected with two elastic balls symmetrically arranged;The middle part of elastic rope close to elastic ball is slidably connected with cleaning brush;The side wall of water storage pool away from drainage net pipe is fixedly connected with recovery pipe;Mud, leaf, etc. Sediment adhered to the inner wall of drainage net pipe can be effectively removed, to avoid causing the diameter of drainage net pipe to be reduced, resulting in the problem of reduced drainage capacity and local waterlogging due to blockage, to reduce the risk of urban waterlogging.
