Description

In the construction of sponge city, it is used for water storage and drainage system on both sides of the road

technical field

The utility model relates to the field of sponge city construction, in particular to a water storage and drainage system used on both sides of a road in the construction of a sponge city.

Background technique

Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city".

The construction idea of "sponge city" emphasizes water absorption, water storage, water seepage and water purification during rainfall, and "release" and use the stored water when needed.

With the construction of urbanization, the effective water storage area is getting less and less, especially the impermeable pavement mainly made of cement prevents precipitation from penetrating into the soil, which makes it difficult to treat water in urban flood seasons, and also in non-flood seasons. Because the effective soil contact area is small and the soil's water-holding capacity is limited, water shortages and even droughts are caused. The existing water storage is generally based on reservoirs, but the ground resources are limited and the water storage capacity is small.

Utility model content

The purpose of this utility model is to provide a water storage and drainage system for both sides of the road in the construction of sponge city, which solves the problems of limited drainage, water locking and low water storage capacity of urban ground resources.

The above-mentioned technical purpose of the utility model is achieved through the following technical solutions:

A water storage and drainage system used on both sides of the road in the construction of a sponge city, including a dry river paved with stones, a filter well for treating impurities, and an underground reservoir. The lowest part of the dry river is connected A water collection pipe is provided, and the water collection pipe is connected to a filter well, and a water storage pipe is connected between the filter well and the reservoir, and a shunt pipe connected to the urban drainage pipe is provided on the inner wall of the filter well, The bottom of the filter well is provided with a silting barrel matching with the clearance of the well wall of the filter well.

With the above structure, the dry river plays the role of the first filter, blocking most of the debris, especially the larger debris, on the surface of the dry river, while the small particles in the water enter through the gaps between the stones In the water collection pipe, the particulate matter will be in the middle and lower part of the water flow due to its own weight, and the flow velocity of the water in the pipe gradually decreases from the middle to the edge, and when the water flow passes through the filter well, the flow cross section increases, and the water flows through the filter well. The flow rate will decrease suddenly when the water flows through the filter well. Therefore, the particulate matter will sink when the water flows through the filter well, so that the particulate matter will be collected in the sedimentation bucket, so that the water flowing into the shunt pipe and the storage pipe will contain less impurities. And the particulate matter in the silting bucket can be cleaned up every once in a while.

It is further preferred that: the opening of the water storage pipe on the filter well is at the same height as the opening of the water collection pipe on the filter well.

With the above structure, it is known that the particles will sink when the water flows into the filter well, so the water storage pipe can be arranged above the diversion pipe and the water collection pipe to collect relatively clean water.

It is further preferred that: the opening of the water storage pipeline on the filter well is provided with a filter screen.

With the above structure, due to the higher position of the water storage pipe, the collected water is relatively clean, but there are still some particles and impurities. The filter screen on the water storage pipe can further purify the water, so as to facilitate post-processing into domestic water .

It is further preferred that: the silting bucket is provided with pulling ears, and the wellhead of the filter well is provided with a lifting mechanism for pulling the silting bucket to the ground.

With the above structure, the sedimentation bucket needs to be cleaned regularly to ensure the cleanliness of the sedimentation bucket, and the lifting mechanism can more conveniently lift the sedimentation bucket out of the filter well for easy cleaning.

It is further preferred that: the lifting structure includes a stand arranged on the ground, the wellhead is provided with a cross bar fixed on the stand, and the cross bar is fixed with a rope that pulls the silting bucket up, and the stand A motor is arranged on the top, and the cross bar is controlled by the motor.

With the above-mentioned structure, in order to prolong the cleaning cycle of the sedimentation bucket, the volume of the sedimentation bucket is generally set larger. Buckets and cleanup handles.

Further preferably, a worm is arranged on the shaft of the motor, and a worm gear matched with the worm is arranged on the cross bar.

With the above structure, the general motor has no self-locking ability, that is to say, when the voltage of the motor is unstable, or when the power of the motor is not enough to provide the pulling force of the silting bucket in an instant or even for a certain period of time, the bucket may be lifted. In the event of falling, the worm gear mechanism provides the motor with self-locking ability to ensure that the sedimentation bucket will not fall when the force is lost.

It is further preferred that: the storage tank includes a spliced and combined rainwater storage module and a geotextile with water seepage function wrapped on the outer layer of the rainwater storage module.

With the above structure, the rainwater storage module is an existing technology, and its water storage capacity reaches 95% of its occupied volume, and its load-bearing capacity is large enough to bear the weight of multiple trucks. A subsidence condition caused by the space occupied by underground water storage.

It is further preferred that: the wellhead of the filter well on the ground is provided with a top cover to prevent sundries from entering the filter well.

With the above-mentioned structure, the top cover can prevent sundries from entering the filter well from the well head.

In summary, the utility model has the following beneficial effects:

1. Use dry rivers and filter wells to reduce the particulate matter contained in the water, and then input it into urban drainage pipes to ensure less sediment input into urban drainage pipes, which can effectively relieve the pressure of urban drainage;

2. Multiple filtrations such as dry rivers, filter wells, and filter screens at the entrance of water storage pipes make the water entering the reservoir relatively clean, and then it can be used as domestic water again after going through the sterilization and disinfection lamp program;

3. The dry river and rainwater storage module of the gravel can well avoid the collapse caused by the space occupied by underground water storage while storing water, and make full use of the underground space to store water; and the seepage geotextile can be combined with the underground soil Water exchange is performed to increase drainage efficiency during the flood season.
