Embodiment 1

[0041] The construction method of green construction recycling and reuse of stagnant water in the shallow source upper layer provided by this embodiment includes the following steps:

[0042] (1) Geological survey: According to the geological survey report, find out the geological and hydrological conditions of the project area; at the same time, find out the obstacles such as underground pipelines and cables in the construction area near the water and the impact of drilling on adjacent buildings. According to the stratum conditions, Select the appropriate construction machinery and supporting facilities, and conduct technical training for various types of work. Site leveling shall be carried out according to the design elevation, and various obstacles affecting the construction of the precipitation well shall be excavated.

[0043] (2) Construction of dewatering wells

[0044] 1. Technical process of dewatering well: install water pump in the well pipe, install pumping contr...

[0068] Embodiment 2 application example

[0069] (1) Jiahejiayuan 4#, 5#, 7# buildings, F area network and underground garage project

[0070] Construction

[0071] Jiahejiayuan 4#, 5#, 7#, F area outlets and underground garage project will recycle and reuse the groundwater of the foundation pit dewatering project of the construction project, further reduce the construction cost of the construction project, increase the rational use of water resources, and consist of municipal water supply and underground On-site temporary water systems for reclaimed water commons.

[0072] apply effects

[0073] This project uses groundwater to replace part of the construction water, which greatly saves water resources, reduces the waste of water resources, solves the technical problem of groundwater reuse, responds to the government's call for establishing a conservation-oriented society, and is well received by the competent unit and the construction unit. support.

Abstract

The invention discloses a construction method of environment-friendly construction and recycling and reusing for shallow source upper layer stagnant water. The construction method comprises the following steps of (1) geological surveying; (2) construction of a dewatering well; (3) mounting construction of water tanks and water pots; and (4) mounting of all water terminal facilities. According to the construction method, groundwater exploited in dewatering engineering is recycled and reused, and the construction cost of a project is reduced; the groundwater is not directly drained into a municipal drainage network, and thus the pressure of municipal pipelines is reduced; and the construction method is suitable for engineering, wherein construction of the engineering needs to reduce the water level of a foundation pit, has high groundwater content and has relatively low requirement on other water quality except for high requirements on construction water quality.

Description

technical field [0001] The invention relates to a construction method for green construction recycling and reuse of stagnant water in the shallow source upper layer, and belongs to the technical field of building construction. Background technique [0002] In areas with a high groundwater level, during the excavation of deep foundation pits for construction projects, because the aquifer is cut off, under the action of pressure difference, groundwater will inevitably infiltrate into the foundation pit continuously. If the foundation pit dewatering and drainage work is not carried out, the foundation pit will be flooded, the construction conditions on site will be deteriorated, the bearing capacity of the foundation will be reduced, and quicksand, piping and slope instability may also be caused under the action of hydrodynamic pressure. Therefore, in order to ensure the safety of foundation pit construction, effective dewatering and drainage measures must be taken to extract g...
