Permeable base course seepage diversion and drainage guiding structure applied to outdoor stone pavement

Abstract

The invention provides a permeable base course seepage diversion and drainage guiding structure applied to outdoor stone pavement. The permeable base course seepage diversion and drainage guiding structure applied to the outdoor stone pavement comprises a ground base layer, a lower permeable concrete layer and an upper permeable concrete layer; the lower permeable concrete layer is fixedly laid onthe ground base layer; the upper permeable concrete layer is fixedly laid on the lower permeable concrete layer; multiple water guide pipes arranged in parallel are buried in the lower permeable concrete layer; multiple water inlets arranged in the axial directions of the water guide pipes are formed in the tops of the water guide pipes; geotechnical cloths covering the water inlets are laid at the tops of the water guide pipes; and each two adjacent water guide pipes are connected with each other through a pressure discharging pipeline component. Compared with the prior art, the permeable base course seepage diversion and drainage guiding structure applied to outdoor stone pavement has the advantage that the problem that a concrete layer is easy to damage and so on because the operationof traditional water guide pipes are not uniform by mainly using a mode of additionally mounting the pressure discharging pipeline components between the two water guide pipes is solved.

Description

technical field

[0001] The invention relates to a seepage and drainage structure for a permeable base, in particular to a seepage and drainage structure for a permeable base used in outdoor stone pavement. Background technique

[0002] In recent years, problems such as the "heat island effect" of domestic cities, waterlogging caused by heavy rains, and the depletion of groundwater resources have seriously affected urban ecological construction and sustainable development. Carrying out the construction of "sponge city" is an important strategic measure to solve the above problems. An important technical means in the implementation process is the use of permeable pavement. As early as 1852, the British developed concrete without fine aggregate. In 1950, Britain applied porous asphalt pavement to airport runways. The United States began to study and design permeable concrete since the 1960s. The Netherlands began to study drainage asphalt mixtures in 1972. In addition, the ...
