5results about How to "Improve anti-settling effect" patented technology

This utility model discloses an anti-settlement inspection well structure, including an asphalt pavement, a well cylinder fixed in the middle of the asphalt pavement, and a placement groove integrally set at the top of the well cylinder. Firstly, through a guide function design, the well cover can be easily combined with the well cylinder. Secondly, through a plug-in support design, the bracket supports the top rod, which in turn drives the support rod to support the central area of ​​the well cover. Therefore, by using the device in this application, the strength of the well cover under stress is improved, thereby enhancing the anti-settlement effect of the inspection well. Through a mechanical linkage design, a limiting rod can be inserted into a limiting hole, ensuring not only the stability of the connection between the well cover and the well cylinder but also increasing the strength of the support rod supporting the well cover. Furthermore, through a locking function design, the angle of the rotating support rod can be locked, ensuring the stability of the limiting rod inserted into the limiting hole.

This utility model discloses a settlement-preventing permeable paving structure for gardens, including a drainage roadbed and permeable bricks. Multiple parallel supporting base plates are distributed on the drainage roadbed, and stress-dispersing bases are mounted on the supporting base plates. The stress-dispersing bases are arranged in an orderly manner along the length of the supporting base plates. Each stress-dispersing base has a stress-dispersing inclined surface at its bottom on both sides and a stress-dispersing vertical surface at its top on both sides. This settlement-preventing permeable paving structure for gardens, by setting vertical and inclined mounting surfaces on the surface of conventional permeable bricks, and in conjunction with the stress-dispersing bases, allows a single permeable brick subjected to vertical pressure to have some of the pressure dispersed horizontally through the contact between the inclined mounting surfaces and the stress-dispersing inclined surfaces. This pressure can then be simultaneously diffused onto other types of permeable bricks, thus reducing the pressure on individual permeable bricks in a localized area.

The technical scheme belongs to the technical field of sprayers and particularly relates to a sprayer which comprises a box body, a liquid storage cavity is arranged in the box body, a rocker is hingedly connected to the box body, a water suction device is arranged in the box body, the water suction device comprises a mounting sleeve mounted on the liquid storage cavity, a piston core that moves in the mounting sleeve and a driving rod arranged on the piston core, a valve core mechanism is arranged between the mounting sleeve and the piston core, the piston core is driven to move in the mounting sleeve to realize the suction and delivery of the solution in the liquid storage cavity through the valve core mechanism, a stirrer is fixed on the piston core, a side wall of the mounting sleeve is provided with a clearance slot for the stirrer to pass through, the length direction of the clearance slot corresponds to the piston movement direction of the piston core, the rocker is in abutting contact with the driving rod, the driving rod drives the piston core to move, and the piston core drives the stirrer to move in the liquid storage cavity, the piston core is automatically reset through the valve core mechanism, continuous reciprocating stirring is formed, the settlement of the liquid medicine is reduced, and the working efficiency is improved.

This invention provides a bio-based epoxy resin, its preparation method, and a highly sealing, environmentally friendly anti-corrosion coating. The bio-based epoxy resin has the following general structural formula: R1 is selected from one or a combination of hydrogen atoms, alkyl groups, and alkyl carbonyl esters; R2 and R3 are each independently selected from one or a combination of hydrogen atoms and alkyl groups; a, b, and c are each independently selected from any integer from 1 to 20; and h, f, and g are each independently selected from any integer from 1 to 3. The highly sealing, environmentally friendly anti-corrosion coating of this invention exhibits good sealing properties, anti-sagging, anti-settling, and long-lasting anti-corrosion performance.

The utility model discloses an expressway reconstruction and expansion soft foundation road section anti-settlement structure which comprises a longitudinal connecting batten, a transverse supporting batten, a longitudinal connecting batten, a transverse supporting batten, a longitudinal connecting batten and a transverse supporting batten, wherein the transverse supporting batten is welded below the longitudinal connecting batten; a splicing mechanism for connecting firmness is arranged above the longitudinal connecting battens; and an anti-sedimentation improving mechanism for enhancing the supporting strength is arranged above the transverse supporting plate strip. According to the anti-sedimentation structure for the reconstruction and expansion soft foundation road section of the expressway, the longitudinal connecting battens can be effectively spliced and lengthened by arranging the splicing mechanism, so that the connecting area of the longitudinal connecting battens and the hard subbase side can be enlarged, the connecting firmness can be greatly enhanced, meanwhile, the anti-sedimentation mechanism is arranged, and the anti-sedimentation effect is improved. By arranging the supporting bracket, the firmness of concrete pouring in the supporting bracket can be greatly enhanced, so that the supporting area and strength of a soft soil foundation can be increased, in addition, a stabilizing mechanism is arranged, the connecting stability of the longitudinal connecting battens and the hard subbase side can be enhanced, and the connecting firmness of the longitudinal connecting battens and the hard subbase side can be further enhanced.
