Description

Sponge City Design Garage Roof Waterproof Structure

technical field

The invention relates to a waterproof structure for the roof of an underground garage, in particular to a waterproof structure for the roof of the garage designed in a sponge city.

Background technique

At present, the country is actively promoting the construction of sponge cities. How to implement the concept of sponge cities is a new problem faced by design workers. Today, with the rapid development of the real estate industry, residential quarters are gradually scaled and standardized. If each community can implement the design concept of sponge city, its cluster effect will have a profound impact on the construction of sponge urbanization. At present, low-rise residential quarters are gradually decreasing, replaced by high-rise and super high-rise communities.

At present, the design of sponge city is widely used in municipal roads, municipal parks, residential quarters and other areas. High-rise residential quarters, especially those with underground garages, if the sponge design is implemented, the following problems will arise: 1) Due to the structure of the garage below the road surface itself It does not have the function of water storage. If the roof is in a flooded environment for a long time, the concrete is easily corroded, resulting in structural safety hazards; 2) If the roof is stored for a long time, rainwater will seep into the basement through deformation joints, expansion joints, etc., resulting in water leakage, which will affect the parking environment. , It also poses a security threat to some auxiliary public equipment such as equipment and electricity rooms, integrated pipelines, etc. inside the garage; 3) The installation of a high-efficiency waterproof layer outside the roof of the garage will not only increase the cost of construction, but also cumbersome maintenance projects in the later period.

Contents of the invention

The object of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a garage roof waterproof structure with reasonable structure, fast drainage speed, and greatly reducing corrosion damage to the concrete structure of the garage roof.

The purpose of the present invention is achieved like this:

A garage roof waterproof structure designed for a sponge city, comprising a garage roof, characterized in that the garage roof is provided with a waterproof and protective layer, a confluence channel, a water-permeable and drainage facility layer, and a water-permeable pavement structure layer, covered by a waterproof and protective layer On the top surface of the roof of the garage, the confluence channel is arranged on the waterproof and protective layer, and the permeable and drainage facility layer and the permeable pavement structure layer are arranged on the waterproof and protective layer in turn, and are located on the side of the confluence channel, and the side of the confluence channel has water seepage gaps. The surface of the waterproof and protective layer, the permeable and drainage facility layer and the permeable pavement structure layer is inclined towards the direction of the confluence channel.

The purpose of the present invention can also adopt the following technical measures to solve:

As a more specific solution, the waterproof and protective layer includes a cement mortar layer, a waterproof coating, a polymer waterproof roll and a reinforced concrete protective layer arranged from bottom to top. The cement mortar layer has a certain density, which is beneficial to a certain waterproof effect. In addition, the surface of the cement mortar has a high smoothness to prevent water accumulation, and then combined with the waterproof coating and polymer waterproof roll, the waterproof effect is greatly improved. On top of the waterproof functional layer, there is a protective functional layer. The protective functional layer is a reinforced concrete protective layer, which has high load-carrying and anti-collision capabilities, so as to improve the structural protection of the garage roof. At the same time, it can also prevent the waterproof coating And the polymer waterproof roll is damaged.

As a further solution, the confluence channel is a drainage channel or an ecological retention pond, and the drainage channel or the ecological retention pond has a certain function of collecting rainwater.

As a further solution, the side wall of the drainage channel is made of porous bricks, and vertical water seepage gaps are left between the porous bricks (and the outer wall surface and the inner wall of the side wall of the drainage channel are not plastered, so that the vertical water seepage gaps are exposed , the accumulated water in the permeable and drainage facility layer and the permeable pavement structure layer will flow into the drainage channel through the seepage gap).

As a further solution, the top surface of the drain is covered with water grates. The surface of the water grate has a plurality of permeable holes running through its upper and lower sides. Pebbles can be placed above the permeable hole for decoration.

As a further solution, the ecological retention pond includes a gravel bedding layer and a coarse sand bedding layer. The ecological detention pond has the functions of water filtration and slowing down of water flow, and can accumulate a certain amount of rainwater.

As a further solution, a decoration layer or a planting layer is provided on the confluence channel. The decoration layer can be a pebble bedding layer, the planting layer can be a soil layer, and can be planted on the soil layer. The decorative layer not only ensures that the rainwater that is too late to infiltrate the road surface can be discharged smoothly, but also beautifies the environment.

As a further solution, the permeable and drainage facility layer includes a geotextile and a water-permeable and hydrophobic board, the geotextile is arranged on the water-permeable and hydrophobic board, and the permeable pavement structure layer is arranged on the geotextile. The geotextile has a number of micropores and has a certain filtering capacity. After the filtered water enters the permeable and hydrophobic board, it can be quickly dredged to avoid long-term immersion of the garage roof caused by accumulated water.

As a further solution, the permeable pavement structure layer includes a lightweight backfill material layer, a thick sandy pebble or graded gravel layer and a permeable concrete layer arranged from bottom to top. This permeable pavement structure layer has good water permeability and avoids water accumulation; moreover, it has good supporting capacity and can be used as a driving road or a pedestrian road to avoid becoming soft after being sprayed with water.

As a further solution, it also includes a drainage pipe and a storage tank. The pipe wall of the drainage pipe is provided with a number of through holes. The drainage pipe is embedded in the permeable pavement structure layer and communicates with the confluence channel and the storage tank. After the permeable pavement structure layer is sprayed with water, part of the water can enter the drain pipe through the through hole, and the other part of the water can enter the confluence channel, and the water in the confluence channel can also enter the drain pipe, and the water flows into the storage tank through the drain pipe Storage, the water stored in the storage tank can be used for plant irrigation.

The beneficial effects of the present invention are as follows:

(1) The waterproof and protective layer of the waterproof structure of the garage roof designed by this sponge city can improve the waterproof ability of the garage roof, and when rainwater falls on the permeable pavement structure layer and passes through the permeable and drainage facility layer, it can be quickly discharged to the confluence channel, There will be no water on the road, which is convenient for pedestrians to walk, and can improve the safety of vehicles. At the same time, it can avoid the corrosion and damage of rainwater to the concrete structure of the garage;

(2) The waterproof and protective layer, the water-permeable and drainage facility layer and the water-permeable pavement structure layer of the waterproof structure of the garage roof in this sponge city design are inclined towards the direction of the confluence channel to further improve the drainage capacity;

(3) The confluence channel of the garage roof of this sponge city design can collect water to the water storage area. After the water is purified and filtered, it can be used for greening and irrigation of plants in the residential area, which is more environmentally friendly.
