Embodiment Construction
[0028] The present invention is further described below with reference to the accompanying drawings and specific embodiments:
[0029] like Figure 1 to 3 As shown, a padding block for improved road water permeability is filled, the filling block being filled in a hole opened on the road, which includes a water prefabricated block 3 and a plurality of catheter 8, the water prefabricated block 3 by a proportion The concrete is made after mixing with the short steel fiber 5, which is formed in a mold that matches the hole, and the sidewall of the water prefabricated block 3 is applied to the sip of the structural adhesive 2, and the top surface is pasted with a structural adhesive with a wire mesh 1, The lower portion of the sidewall of the water prefabricated block 3 is attached to the extruded plate 4, and the bottom surface is bonded to the retrofolding geotextile 6, and a steel tray 7 is attached to the bottom surface of the anti-filter 7, the steel tray 7. There is a plurality o...

The invention relates to a filling block for improving the water permeability of a road and a construction method, wherein the filling block is filled in a hole formed in the road and comprises a water-permeable precast block and a plurality of guide pipes; the water-permeable precast block is manufactured by mixing concrete and short steel fibers according to a certain proportion and then pouring the mixture into a mold matched with the hole; structural adhesive is smeared on the upper portion of the side wall of the water-permeable precast block, a steel wire mesh is pasted on the top face of the water-permeable precast block through the structural adhesive, an extruded sheet is pasted on the lower portion of the side wall of the water-permeable precast block, anti-filtering geotechnical cloth is pasted on the bottom face of the water-permeable precast block, a steel tray is installed on the bottom face of the anti-filtering geotechnical cloth, and a plurality of drainage holes are formed in the steel tray; a part of the drainage holes are internally provided with guide pipes, and the lower ends of the guide pipes extend into the base layer soil. The product can be used for improvement of water permeability performance of old roads or applied to new road projects after prefabrication, and the application range is wide; during use, soil slurry can be prevented from overflowing, and the good water permeability of the filling block is kept.
Description
Technical field [0001] The present invention relates to the field of road construction techniques, and more particularly to filling blocks and construction methods for the improvement of road water permeability transformation. Background technique [0002] Under the rapid development of sponge cities, the roads at all levels of the city are not only on the function of the traffic organization, and they have also drained drainage, alleviating the function of urban floods. Therefore, the improvement of road transmission and drainage performance is a key factor in the improvement of the road itself. Although the traditional water-water concrete has good permeable performance, its own structural strength is not high, it cannot withstand a large traffic load, and the water-based concrete is a dry material concrete, which can only rely on artificial paving, and the construction process is complicated. Inventive content [0003] In order to solve the above problems, the present inventi...
