The invention relates to packaging barrel hollow blow molding equipment based on plastic recovery, and belongs to the technical field of packaging barrel blow molding. Comprising a shell, a forming assembly is arranged at the front end of the shell, a collecting assembly is arranged at the bottom of the forming assembly, a feeding assembly is fixedly connected to the top of the collecting assembly and comprises a supporting frame, the bottom of the supporting frame is fixedly connected with the top of the shell, and a supporting plate is fixedly installed at the tail end of the top of the supporting frame; and a servo motor II is fixedly mounted at the front end of the supporting plate. By arranging the collecting assembly and the feeding assembly, leftover materials are collected through a funnel and a collecting bin, the leftover materials are melted into liquid through a heating rod and a heating ring and then flow into a feeding pipe, at the moment, a first servo motor drives a screw to rotate, and therefore liquid raw materials are discharged into a discharging pipe and a storage box; therefore, the utilization rate of the leftover materials of the plastic raw materials is improved, and the production loss and the cost are reduced.

The utility model relates to a kind of high-rise residential roof solar energy infrastructure, including foundation support and waterproofing membrane layer, waterproofing membrane layer is set on roof structure board by foaming agent pitch layer or concrete pitch layer, insulating layer is laid on waterproofing membrane layer, rigid concrete surface layer is set on insulating layer, foundation support prefabricated support or direct locking support on rigid concrete surface layer. Waterproofing membrane layer exceeds the periphery of foundation support ≥100mm. Foundation support and rigid concrete surface layer are provided with waterproof concrete surface layer. 10-30mm separation joint is set within 100mm outside foundation support root on waterproof concrete surface layer, and oil paste is embedded in separation joint. Its structure is simple, can give consideration to construction convenient, improve original roof waterproofing and thermal insulation performance and reduce maintenance use cost.

This utility model belongs to the field of building engineering technology, specifically relating to a protective edge-guarding groove structure for waterproof membrane. It is used to protect the reserved edge of the waterproof membrane when it is being installed at the edge. The structure includes a folded, integrally formed protective body, comprising an upper protective sheet and a lower protective sheet. A groove is formed between the upper and lower protective sheets to accommodate the reserved edge of the waterproof membrane. The two ends of the two protective bodies can be spliced ​​together to form a whole. By inserting the reserved edge of the waterproof membrane into the groove inside the protective body when it is installed at the edge, the structure effectively protects the waterproof membrane from damage, aging, and contamination during construction, significantly reducing the risk of water seepage, improving the quality of waterproofing construction, and reducing subsequent maintenance and rework costs.

The utility model relates to the technical field of industrial and mining equipment, and discloses a crystalline titanium liquid slurry uniform spreading device which comprises a belt conveyor body, a mounting beam is fixed to the discharging end of the belt conveyor body and stretches across a belt, a mounting groove is formed in the bottom of the mounting beam, and the mounting groove extends along the mounting beam. And a counterbore penetrating through the mounting groove is formed in the top of the mounting beam, a bolt is arranged in the counterbore, a clamping block matched with the mounting groove is screwed on the bolt, and the clamping block is used for clamping the upper half part of the scraper into the mounting groove. The scraper device has the advantages that the scraper is fixed to the bottom of the mounting beam through the clamping blocks, the connecting mode is more stable, the scraper is not prone to loosening and falling off, the frequency of later maintenance and adjustment is reduced, and uniform laying of slurry is guaranteed.

The application discloses a kind of super-high water pressure dewatering well drainage plugging micro-permeation self-draining structure, it includes the steel pipe well being arranged at basement dewatering well mouth, steel pipe well upper end port sealing, steel pipe well upper is equipped with grouting pipe and drainage pipe, steel pipe well is filled with the gradation sandstone being fixed by hardening cement slurry, basement ground is laid from below to above with concrete cushion layer, waterproof layer and bottom slab reinforced concrete layer, bottom slab reinforced concrete layer is equipped with bottom slab post-cast concrete pit, steel pipe well upper end port, grouting pipe and drainage pipe are located in pit, pit is poured with reinforced concrete, pit above is laid with drainage plate extending to catch basin, the top of bottom slab reinforced concrete layer and drainage plate is laid with concrete surface layer.The application further discloses a kind of construction method of the above-mentioned super-high water pressure dewatering well drainage plugging micro-permeation self-draining structure.The purpose is to provide a kind of super-high water pressure dewatering well drainage plugging micro-permeation self-draining structure and its construction method, its well sealing speed is fast, well sealing effect is good, unnecessary maintenance is reduced in later period.

The utility model relates to the technical field of monitoring devices, and discloses a roadbed settlement monitoring device which comprises two measuring rods, the two measuring rods are distributed up and down, the interiors of the two measuring rods are of hollow structures, a plurality of sliding blocks are fixedly installed on the surfaces of the two measuring rods, and a plurality of through grooves are formed in the surfaces of the two measuring rods. According to the monitoring device provided by the utility model, through the guide cooperation of the slide block and the L-shaped groove and the automatic locking structure of the clamping block and the first spring, the rapid splicing and dismounting between the upper and lower measuring rods are realized, the dismounting convenience of the device is improved, the locking can be realized only by aligning the slide block and the L-shaped groove and pressing and rotating the slide block and the L-shaped groove during splicing, the whole measuring rod does not need to be rotated, the field operation intensity is reduced, and the working efficiency is improved. The device can flexibly meet the increasing and decreasing requirements of measuring rod sections with different embedding depths, locking of the clamping block on the sliding block can be relieved only by pulling down the moving ring during disassembly, the problem of thread corrosion clamping stagnation does not need to be solved, the repeated utilization rate of the device is increased, and the field construction efficiency of roadbed settlement monitoring is remarkably improved.
