An environment-friendly prefabricated double-box deep-hole drainage well and its construction method

Abstract

The invention discloses an environment-friendly prefabricated double-box deep-hole drainage well and a construction method thereof. The drainage well has two interconnected box chambers, one of which is used as a sediment box and the other is used as a drainage box. There are drainage holes at the bottom of the drainage box that go deep into the groundwater layer, and the rainwater treated with sediment can be directly discharged into the groundwater layer without additional purification. In addition, a detailed construction method is disclosed aiming at the characteristics of the drainage well. The invention has the advantages of simple structure, convenient construction and easy maintenance, is applicable to various road municipal situations, can effectively treat rainwater, meets environmental protection requirements, and effectively saves and protects water resources.

Description

technical field

[0001] The invention relates to the field of road municipal drainage, in particular to an environment-friendly prefabricated double-box deep-hole drainage well and a construction method thereof. It is suitable for the drainage needs of various highway municipal, suburban and mountainous road projects. Background technique

[0002] With the progress and development of domestic highway construction concepts, the impact on the surrounding environment during and after road construction has gradually been included in the consideration of owners and designers, and people are increasingly paying attention to environmental protection requirements.

[0003] In suburban or mountainous roads, the current common drainage method is to use roadside drainage ditches to collect rainwater and road surface water and discharge them to water flow areas such as rivers and lakes. Although this reduces the cost and cost, it also brings certain hidden dangers to environmental prote...

Examples

Embodiment 1

[0110] An environmentally friendly prefabricated double-box deep-hole drainage well, including a sediment tank for receiving rainwater or road surface water and sedimentation, and a drainage tank for receiving water treated with sediment in the sediment tank and discharging it into the ground. The room is connected through a connecting pipe. The roof of the sediment tank is provided with a grid-style well cover, the roof of the drainage tank is provided with a closed manhole cover, and the bottom of the drainage tank is provided with a drainage hole directly reaching the groundwater layer, and a drainage pipe is provided in the drainage hole. A mortar retaining wall is arranged between the drain hole and the drain pipe. The upper end of the drain hole is higher than the bottom of the drain tank. The connecting pipe is arranged horizontally, and the horizontal position of the connecting pipe is higher than that of the sediment tank and the bottom of the drainage tank. Both the...

Embodiment 2

[0123] The manhole cover on the top of the sediment tank is a 760*760mm square grid manhole cover, the manhole cover on the top of the drainage tank is a circular manhole cover with a diameter of 600mm, and the drainage well is located in the detention tank.

[0124] The remaining parameters are the same as in Example 1. Since the drainage well is located in the detention pond, the top of the drainage well should be higher than the bottom of the pond, so as to prevent a large amount of residue from entering the drainage well with the water flow, causing serious deposition and increasing the burden of dredging. So design d1=230mm.

[0125] In addition, this example does not need to be provided with a conveying drainage pipe, so there is no need to perforate the drainage well wall.
