Description
Technical Field
The utility model relates to a two ingredient polyurethane mixture technical field of the concrete that permeates water, concretely relates to two ingredient polyurethane mixture of concrete that permeate water generate device.
Background
The pervious concrete in urban roads is mainly used for sidewalks, non-motor vehicle lanes or garden roads and the like, is greatly influenced by the passing of peripheral pedestrians during construction, and has low initial strength after forming due to a special pervious structure, so that the pedestrians and animals can pass through the roads and easily leave marks on a surface layer, if the surface cannot be timely recovered, the cement can be normally broken in a whole version for pouring again after initial setting. Even if the pervious concrete is cured, after the strength reaches the design requirement, the diseases such as pits, cracks and the like are very easy to occur due to the reasons that vehicles run in violation of rules and the like, when the cement-based material is repaired, obvious lap joints inevitably occur, the apparent quality is difficult to guarantee, the two-component polyurethane adhesive mixture can be used for simply and quickly filling and repairing the diseases, the lap joints are not easy to perceive by naked eyes, and the maintained apparent quality is effectively improved.
The existing production mode of the pervious concrete two-component polyurethane mixture is as follows: at present, the crushed stone and the two-component polyurethane A glue are mixed in a mixing tank, then the mixture is sieved and leached out of the crushed stone, then the mixture is sent into another mixing tank to be added with the reinforcing agent and the two-component polyurethane B glue for mixing, and finally the well-mixed mixture is used for filling the well-cleaned disease treatment pit slot. The process is complicated, the required equipment is more, and the time and the labor are wasted.
SUMMERY OF THE UTILITY MODEL
To the not enough of above-mentioned prior art, the utility model provides a two ingredient polyurethane mixture of concrete that permeate water generate device can permeate water two ingredient polyurethane mixture of concrete of quick continuous production.
In order to achieve the above object, the utility model provides a following technical scheme: a pervious concrete two-component polyurethane mixture generating device comprises a first horizontal spiral feeding device and a second horizontal spiral feeding device; the first spiral feeding device comprises a cylinder wall and a spiral rod arranged in the cylinder wall, a feeding hole and a discharging hole are respectively formed in two ends of the cylinder wall, a through hole is formed in the position, close to the discharging hole, of the bottom of the cylinder wall, and a filter screen is arranged in the through hole; and the discharge hole of the first spiral feeding device is positioned above the feed hole of the second spiral feeding device.
The utility model has the advantages that: the two-component polyurethane A glue and the macadam are added into the first spiral feeding device, the macadam which is not mixed after the mixture passes through the filter screen at the bottom of the first spiral feeding device is leached out, then the mixture falls into the second spiral feeding device, the reinforcing agent and the two-component polyurethane B glue are added into the second spiral feeding device, and the mixture is conveyed to a pit groove at a disease position after being mixed. The utility model discloses simple structure, production simple process is swift.
Drawings
FIG. 1 is a schematic structural view of the present invention;
reference numbers in the figures: 1. a first screw feeder; 2. and the second spiral feeding device.
Detailed Description
In order to describe the present invention more specifically, the present invention is described in detail below by way of examples, but the scope of the present invention is not limited thereto.
As shown in fig. 1, the present invention comprises a horizontal first screw feeder 1 and a second screw feeder 2; the first spiral feeding device 1 comprises a cylinder wall and a spiral rod arranged in the cylinder wall, wherein a feeding hole and a discharging hole are respectively formed in two ends of the cylinder wall, a through hole is formed in the position, close to the discharging hole, of the bottom of the cylinder wall, and a filter screen is arranged in the through hole; the discharge hole of the first spiral feeding device 1 is positioned above the feed hole of the second spiral feeding device 2.
The discharge port of the second spiral feeding device 2 is arranged at a pit groove at a disease position, the two-component polyurethane A glue and the broken stone are added into the first spiral feeding device, the broken stone which is not mixed after the mixture passes through the filter screen at the bottom of the first spiral feeding device is leached out, then the mixture falls into the second spiral feeding device, the reinforcing agent and the two-component polyurethane B glue are added into the second spiral feeding device, and the mixture is mixed and then conveyed to the pit groove at the disease position. The medicament can be added from the feed inlet of the spiral feeding device, and a medicament inlet can also be formed in the wall of the spiral feeding device.
Adopt the utility model discloses carry out the mixture preparation, need sieve in advance to the detritus material, dry to moisture content below 0.5%, spiral feeder utensil all need keep dry, at first add excessive two ingredient polyurethane A in the detritus material and glue the stirring, make the rubble face evenly paint A glue back and sieve the drop detritus material, it is accurate to use the rubble surface not have natural glue that drips, and it is even to add the abundant mix of plastics base rubber reinforcement filler in the mix bucket after, add two ingredient polyurethane B glue at last and fully mix.
The double-component polyurethane glue mixture is the primary color of stone, and can be independently added with toner or sprayed with color according to the design requirement.
The two-component polyurethane AB glue and the permeable concrete surface layer crushed stones with different grades are doped with the plastic-based rubber reinforcing filler, and the results of the comparative compression test of the mixtures with different mixing ratios show that when the limestone crushed stones with the grades of 0.5-1mm are used, the mixture strength can reach 26MP at the highest when the mixing ratio of the mass ratio (0.09 of the two-component polyurethane A glue to 0.03 of the two-component polyurethane B glue to 0.85 of the limestone crushed stones with the grades of 0.5-1mm to 0.02 of the plastic-based rubber reinforcing filler) is used.
When the two-component polyurethane adhesive mixture is filled on site, layered filling is needed, the filling thickness is not more than 5cm each time, a flat shovel knife is used for tamping after filling, and the closing surface is forcefully compacted during closing surface, so that the mixture is ensured to be in close contact with broken stones, and no obvious gap fault exists.
The above-mentioned embodiments further describe the objects, technical solutions and advantages of the present invention in detail, it should be understood that the above description is only the embodiments of the present invention, and is not intended to limit the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
