Embodiment 1
[0033] Such as Figure 1-Figure 3 As shown, this embodiment discloses a sponge city drainage system for hutongs and low-lying courtyards, including a ground drainage system arranged around buildings, and a water distribution area is set between the ground drainage system and the building. The ground seepage and drainage system includes a water-permeable layer, a first cement mortar layer, a gravel layer, an integrated seepage and drainage pipeline, an anti-seepage layer, a second cement mortar layer, and a plain soil compaction layer from top to bottom. The ground seepage and drainage system Also includes gullies and integrated stormwater lift pump wells. Among them, the permeable layer uses 60mm thick concrete permeable bricks, and coarse sand fills the joints. When it rains lightly, the rainwater can be quickly infiltrated without water accumulation on the ground; the first cement mortar layer uses 30mm thick 1:6 dry hard cement mortar; the gravel layer Use 150mm thick grad...

The invention discloses a sponge urban seepage and drainage system and method for hutongs and low-lying yards. The system comprises a ground seepage and drainage system. The ground seepage and drainage system comprises a water permeation layer, an anti-seepage layer and a seepage and drainage integrated pipeline. The seepage and drainage integrated pipeline is arranged between the anti-seepage layer and the water permeation layer, and the seepage and drainage integrated pipeline is communicated with a rainwater inspection well. According to the sponge urban seepage and drainage system and method for hutongs and low-lying tyards, the seepage and drainage integrated pipeline and the anti-seepage layer are combined, so that the drainage problem of the hutongs and low-lying yards can be solved, and the damage of rainwater permeation to the shallow foundations of old buildings can be avoided. The method has the beneficial effects of being short in construction period, low in construction noise, small in environmental influence, simple in structure, low in cost, convenient to install, high in cost performance, good in comprehensive effect and the like.
Description
technical field [0001] The invention relates to the technical field of sponge city construction, in particular to a sponge city seepage drainage system and method for alleys and low-lying courtyards. Background technique [0002] During the transformation and construction of sponge cities, it was found that there are a large number of hutongs and low-lying courtyards in the built-up areas of major cities across the country, especially in the central areas of old urban areas, and the proportion of the area is relatively large. There are many buildings, once a heavy rain occurs, the water accumulation will be serious, and even backflow will occur. Therefore, in the transformation of the sponge city, how to solve the drainage and water collection problems of hutongs and low-lying courtyards, and at the same time avoid rainwater penetration on old buildings. Damage to shallow foundations of buildings. [0003] Based on this, the prior art still needs to be improved. Contents ...
