Description

A device for collecting and utilizing water at a construction site

technical field

The utility model relates to the technical field of water use at construction sites, in particular to a device for collecting and utilizing water at construction sites.

Background technique

With the expansion of the scale of construction projects and the gradual improvement of use functions, most buildings have basement structures. During the construction of engineering structures, each floor needs fire-fighting water for construction safety; and after the structural concrete is poured, a large amount of maintenance water is required; Later masonry, decoration and installation projects all need to lead construction water to the place of use. The general method is to directly access the tap water from the first floor. When the floor reaches a certain height, the tap water pressure is not enough, and the pump needs to be increased to supplement the pressure.

This form of temporary construction water and fire-fighting water is often used, and the pipeline installation is simple, but there are also many disadvantages:

1. A large amount of tap water is used, which increases the economic cost of the project;

2. Using a booster pump when the tap water pressure is not enough will not only increase the equipment cost but also increase the maintenance cost;

3. During the construction period, especially during the construction of the main structure, a large amount of water will accumulate in the basement due to the use of water and atmospheric precipitation, which will lead to an increase in pumping costs.

detailed description

The technical scheme of the utility model will be described in detail below with the accompanying drawings, but the protection scope of the utility model is not limited to the described embodiments.

Embodiment 1: The water collection and utilization device at the construction site as shown in Figure 1, including a water storage tank 1, a living area water tank 2 and two sets of water supply systems for main buildings (Building A, Building B); the storage tank 1 is constructed in the basement During the process, a purposefully reserved natural water sump is a 5m×5m×2m elevator foundation pit. The reservoir 1 forms a connection channel 21 with the dewatering well on the construction site through a water pump to drain the overflowing water from the dewatering well and Atmospheric precipitation is collected as a water source for the entire device. During the construction of the above-ground project (2-3 floors), a water tank with a size of 2.5m x 2.5m x 2m is made of welded steel plates in the basement, and the fire-fighting water pipes of each layer on the construction site use the official fire-fighting water pipes of the project, which greatly reduces the cost. The water supply system of the main building is shown in Figure 2. After the structure of the construction site is capped, water tanks 31 and 32 are respectively arranged on the top floors of Building A and Building B. The water in pool 1 is pumped to the water tanks 31 and 32 at the top of the two towers. When the water tanks 31 and 32 on the top floor are full to 1.8m, the ball valves 303 and 304 installed in the water tanks on the top floor close the water inlets to increase the water pressure in the fire-fighting water pipes. , when it increases to a certain pressure value, the outlet pressure gauges 401 and 402 of the -3 layer water pumps respectively control the first multi-stage booster pump 42 and the second multi-stage booster pump 43 to stop running, thereby achieving automatic control; Install one-way valves 301 and 302 at a distance of ≥5m from the water tank on the top floor in Building B to ensure sufficient water pressure to open the one-way valves 301 and 302. After the water tanks 31 and 32 on the top floor are filled, the water will be used to generate pressure by the weight of the water to supply water for the construction and production of the two towers. (At this time, the fire pipe is the outlet pipe), which reduces the frequency of use of the water pump on the -3 floor and saves electricity costs; install additional bypass pipes 305, 306 below the one-way valves 301, 302 to lead to the water tanks 31, 32 on the top floor as water inlet pipes. The fire water pipe is both the water inlet pipe and the water outlet pipe, achieving the dual-purpose type of the fire water pipe, which greatly reduces the installation cost.

As shown in Figure 3, a submersible pump 41 is installed in the reservoir 1 to pump water into the living area water tank 2 through the connecting passage 22, and a water level controller 5 is installed in the living area water tank 2 to automatically control the water in the living area. The water tank 2 in the living area is equipped with a water level controller, a water flow probe 203, an upper probe 202 and a lower probe 201. The upper probe 202 is located at the top of the water tank 2 in the living area, the lower probe 201 is located at the bottom of the water tank 2 in the living area, and the water flow probe 203 is located at the bottom of the water tank 2 in the living area. At the water outlet of the submersible pump, the water level controller 5 is connected to the water flow probe 203 , the upper probe 202 , and the lower probe 201 through a four-core control line 25 and is connected to the submersible pump 41 for control.

As shown in Figure 4, the above-mentioned device is used to collect the overflowing water in the basement dewatering well and the accumulated water in the basement as a water source, and at the same time, it is used as water for firefighting in the main building, water for concrete maintenance, water for dust suppression on the road at the construction site, and water for flushing toilets in workers’ dormitories.

As stated above, although the invention has been shown and described with reference to certain preferred embodiments, this should not be construed as limiting the invention itself. Various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
