DETAILED DESCRIPTION

[0022] The utility model will be further explained in connection with the drawings and examples.

[0023] Among the existing found implementable technologies, the following is described.

[0024] The open drain well in building construction is a common drainage facility, mainly used for draining underground water and surface water during building construction to ensure the dryness of the construction site and the smooth progress of foundation construction. The open drain well structure is usually composed of a well head, a well wall, a filter layer, and a well bottom. The well head is higher than the ground and is provided with a protective fence and a well cover for safety protection and convenience of equipment installation and personnel access. The well wall is built with brickwork, concrete, or other materials to support the surrounding soil and prevent collapse. The filter layer is located inside the well wall and is composed of gravel, sand, and other granular materials, which can filter underground water and prevent silt from entering the well, while increasing the permeability of the well. The well bottom is generally in the shape of a pot bottom or a flat bottom and is provided with a sediment pit for collecting silt and debris.

[0025] The principle of the open drain well is to use gravity to make underground water or surface water seep into the well through the well wall and the filter layer. Due to the presence of the filter layer, the water is filtered during the seepage process, ensuring that the water entering the well is relatively clear and reducing the impact of impurities on subsequent drainage equipment. The sediment pit allows a small amount of silt and other impurities carried by the water to settle down, avoiding excessive accumulation in the well that affects the water storage and drainage capacity of the well.

[0026] The open drain well is arranged at the corners and midpoints of the four sides of the rectangular foundation pit, and can be uniformly arranged along the circumference for circular foundation pits. The spacing of the wells is generally 20-30m, and the specific spacing should be determined according to the seepage amount of the foundation pit and the pumping capacity of the water pump, considering the geological conditions: in areas with strong permeability of the soil layer or abundant underground water, the number and depth of the open drain wells should be appropriately increased; in areas with weak permeability of the soil layer, the spacing of the wells can be appropriately increased, in combination with the drainage direction: the arrangement of the open drain well should be combined with the laying of the drainage pipeline to ensure that the pumped water can be smoothly drained to the designated location, such as the drainage system of the construction site or the urban drainage network.

[0027] Open well hole forming: mechanical hole forming or manual hole forming can be used, mechanical hole forming is fast, but has higher requirements for the site; manual hole forming is suitable for areas with complex geological conditions or where machinery cannot reach. During the hole forming process, the verticality and diameter of the hole should be ensured to meet the design requirements, and the hole wall should be prevented from collapsing. Filter filling: fill filter material such as gravel and coarse sand between the well pipe and the hole wall, the particle size of the filter material should be determined according to the size of the soil particles, generally 2-5mm. When filling the filter material, it should be ensured to be uniform and dense to improve the permeability of the well. Wellhead treatment: the wellhead should be higher than the ground by a certain height to prevent ground water from flowing into the well. Protective fences and warning signs should be installed around the wellhead to ensure construction safety.

[0028] Selection of water pump type for open well drainage device: common water pumps include submersible pumps, centrifugal pumps and deep well pumps, etc. Submersible pumps are suitable for shallow well drainage and have the advantages of easy installation and small size. Centrifugal pumps are suitable for large flow and low lift conditions. Deep well pumps are suitable for deep well drainage. Water pump parameters: select appropriate water pumps according to the water yield and lift requirements of the open well. The water yield should be calculated based on the seepage quantity of the foundation pit and the construction water quantity. The lift should meet the requirements of water drainage to the designated location.

[0029] Safety protection: during the construction and use of the open well, safety protection measures such as setting up protective fences and warning signs should be strengthened to prevent personnel from falling and objects from falling into the well.

[0030] Water quality monitoring: regularly monitor the water quality of the pumped water to prevent groundwater pollution. If abnormal water quality is found, the cause should be found out and appropriate measures should be taken.

[0031] Coordination with the surrounding environment: during the drainage construction process, attention should be paid to protecting the surrounding environment to avoid the impact of drainage on surrounding buildings, roads and farmland, etc. If necessary, appropriate protective measures should be taken.

[0032] Regular inspection: regularly inspect the open well, including whether the well wall has cracks, leakage, etc., whether the filter layer is blocked, whether the water pump is running normally, etc.

[0033] Cleaning the sediment pit: regularly clean the sediment pit at the bottom of the well to prevent excessive accumulation of mud and debris, which may affect the normal operation of the well.

[0034] Replace damaged parts: if the well wall, filter layer, water pump and other parts are found to be damaged, they should be replaced in time to ensure the normal operation of the open well.

[0035] Prevent pollution: during the use of the open well, attention should be paid to prevent sewage, garbage and other pollutants from entering the well to ensure the water quality of the well water.
