Description

Gutter inlet structure for concave green land or rainwater garden

Technical Field

The utility model belongs to the field of urban drainage engineering, and particularly relates to a gutter inlet structure for a sunken green land or a rainwater garden.

Background

The gutter inlet is a structure for collecting rainwater on a rainwater pipe duct or a confluence pipe duct. Rainwater on the street road surface firstly flows into the drainage pipe channel through the connecting pipe through the rainwater inlet. The form, number and arrangement of the rain openings are determined according to the quantity of the produced catchment areas, the drainage capacity of the rain openings and the road form.

At present, outdoor rainwater openings are all arranged on a hardened pavement, are flush with the ground or are slightly lower than the ground, and collect rainwater on the hardened pavement; however, when the rainwater infiltrated into the green land and the rainwater garden without the rainwater inlet is saturated, the rainwater stays in the green land, the water accumulation in the green land is too much, the growth of green plants is not facilitated, and the soil is further sunk and collapsed.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a gutter inlet structure for a sunken green or rainwater garden. When the overflow rainwater openings are arranged in the lower concave green land and the rainwater garden, after the green land absorbs enough rainwater to be saturated and reaches the designed water storage height, the rainwater exceeding the standard can flow into a rainwater pipeline through the overflow rainwater openings, so that the green plants can be protected from growing better, and the soil in the green land can be prevented from sinking and collapsing.

The technical scheme is as follows: a gully configuration for a recessed green or rain garden, the gully configuration being disposed in the recessed green or rain garden, the recessed green or rain garden being h millimetres below ground, wherein: h is more than or equal to 100 and less than or equal to 200;

the inlet for stom water structure includes the well room, the bottom of well room is equipped with well seat basis, the lower part is equipped with the rainwater connecting pipe that is linked together with the rainwater pipe network in the well room, the top adaptability of well room is equipped with the walling crib on perpendicular to installation ground, inlay the overflow well lid that is equipped with perpendicular to installation ground in the walling crib, wherein:

the top of the well chamber is higher than the recessed greenery or rain garden by H millimeters, wherein: h is more than or equal to 50 and less than or equal to 100.

Furthermore, cobble buffer zones are arranged around the top of the well chamber.

Further, the well chamber and the well seat foundation are built on the original soil layer of a sunken green land or a rainwater garden.

Further, the rainwater connecting pipe is made of HDPE.

Furthermore, the overflow well lid is a rainwater grate made of stainless steel or cast iron.

Further, the well chamber is a cylindrical well chamber or a cuboid well chamber.

Has the advantages that: according to the rainwater drainage system, the rainwater openings arranged in the lower concave greenbelts and the rainwater gardens can drain rainwater exceeding the standard in the greenbelts to the rainwater storage tank or the municipal rainwater pipe network through the pipelines, so that the service life of green plants can be prolonged, and the soil in the greenbelts can be prevented from sinking and collapsing.

The specific implementation mode is as follows:

the following describes in detail specific embodiments of the present invention.

As shown in fig. 1 and 2, a gully configuration for a sunken green or rain garden, the gully configuration being disposed in the sunken green or rain garden, the sunken green or rain garden being lower than the ground by h mm, wherein: 100 ≦ h ≦ 200, in this embodiment h ≦ 100, in another embodiment h ≦ 200, in yet another embodiment h ≦ 140;

the inlet for stom water structure includes well room 3, the bottom of well room 3 is equipped with well seat basis 4, the lower part is equipped with rainwater connecting pipe 5 that is linked together with the rainwater pipe network in the well room 3, the top adaptability of well room 3 is equipped with walling crib 2 perpendicular to installation ground, inlay in the walling crib 2 and be equipped with the overflow well lid 1 perpendicular to installation ground, wherein:

the top of the well 3 is higher than the sunken greenery or rain garden H mm, where: h ≦ 50 ≦ 100, H ≦ 50 in this embodiment, 100 in another embodiment, and 80 in yet another embodiment.

Furthermore, a cobble buffer zone is arranged around the top of the well chamber 3. Cobblestones are laid around the rainwater port, so that the rainwater port structure can be protected from being damaged on one hand; on the other hand, the rainwater on the periphery can be prevented from entering the rainwater port structure in a centralized manner, and the buffering effect is achieved.

Further, the well chamber 3 and the well seat foundation 4 are built on the original soil layer of a sunken green land or a rainwater garden.

Further, the rainwater connection pipe 5 is made of HDPE (high density polyethylene).

Further, the well base 4 is made of plain concrete.

Further, the well chamber 3 is made of brickwork which is plastered by cement mortar.

Further, the well ring 2 is made of concrete.

Further, the overflow well cover 1 is a rainwater grate made of stainless steel. In another embodiment, the overflow well cover 1 is a rain grate made of cast iron.

Further, the well 3 is a cylindrical well. In another embodiment the well 3 is a cuboid well.

When raining, the building roof, the residential area road surface and the square runoff rainwater are organically gathered into the low-influence development facility, namely, the roof rainwater passes through the rainwater vertical pipe and the drainage ditch, the outdoor road rainwater passes through the curb opening and can enter the concave greenbelt or the rainwater garden to be detained, seeped, purified and stored, the rainwater exceeding the standard flows into the well chamber 3 through the overflow well cover 1 arranged at the overflow rainwater port of the concave greenbelt or the rainwater garden, and is directly drained into the residential area rainwater pipe network through the rainwater connecting pipe 5. The rainwater collecting system not only ensures that initial rainwater does not directly enter a residential area rainwater pipe network, replenish underground water and irrigate greenbelts, but also avoids the harm of overproof rainwater to greenbelts and gardens. The sunken greenbelt or the rainwater garden is 100-200 mm lower than the peripheral field, enters the rainwater inlet of the sunken greenbelt, and is provided with rainwater runoff buffering measures such as pebble ditches and the like.

Installation description: the overflow gutter inlet is arranged in a concave green land or a rainwater garden, and the height H of the top of the well chamber 3, which is higher than the ground of the concave green land, is 50-100 mm to meet the design requirement of the water storage capacity of the concave green land; cobblestones are laid around the rainwater port to prevent the cobblestones from being damaged; peripheral rainwater is easy to disperse into the concave green land; if the peripheral rainwater enters concentratedly, a buffering measure such as a cobblestone buffering belt is arranged at the inlet.

The embodiments of the present invention have been described in detail. However, the present invention is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present invention.
