Description

A construction device for collecting rainwater and automatic drainage. Technical Field

[0001] This utility model belongs to the field of drainage construction technology, specifically relating to a construction device for collecting rainwater and automatic drainage. Background Technology

[0002] During the construction of traditional underground parking garage roof slabs, rainwater drainage typically relies on temporary drainage ditches combined with water pumps. For example, Chinese Patent Application No. 202420037109.1 discloses a device for collecting and reusing rainwater. This device includes a rainwater pipe installed at the lowest point of the post-cast strip of the parking garage roof slab. The end of the rainwater pipe furthest from the post-cast strip is connected to a sedimentation tank, which contains a filter assembly for filtering rainwater. This application effectively drains rainwater promptly, improving construction safety.

[0003] The above-mentioned solution can drain and store rainwater, and then effectively utilize it after treatment. However, because the rainwater pipe is a single, rigid pipe, and construction debris, branches, and leaves inevitably accumulate on the structural roof of the underground parking garage, and because the rainwater pipe is a multi-sectioned bend with vertical ends and an inclined middle section, the resulting central bend is a rigid channel. If large objects or sticks are difficult to maneuver, they can easily get stuck at this point, and over time, they can further trap other solid impurities. This can easily lead to blockages in the rainwater pipe, rendering the system unusable. Furthermore, the system has low drainage efficiency and requires dedicated personnel to monitor and control the water pump.

[0004] Therefore, it is necessary to research and develop a construction device for rainwater collection and automatic drainage during the construction of underground garage roof slabs. Summary of the Invention

At least two elastic fasteners 5 are installed on the outside of the inclined pipe 62. A tie rod 7 is installed on the top of the elastic fastener 5, and a spring 8 is provided between the tie rod 7 and the bottom of the top plate 1 of the structure.

[0031] The water pump 11 is used to drain rainwater from the collection well 13. Its input end extends to the bottom of the collection well 13, and its output end extends to the outside of the collection well 13. Rainwater collected through the floor drain 3 is discharged into the collection well 13 through the conveying pipe 6 to collect rainwater; when the water level is too high, the water pump 11 is started to drain the rainwater from the collection well 13.

[0032] Furthermore, in the above technical solution, a conversion joint is provided at the junction of the floor drain 3 and the first vertical pipe 61. A water-swellable rubber sealing ring is sleeved on the outside of the conversion joint. The first vertical pipe 61 and the second vertical pipe 63 are vertically distributed, and the first vertical pipe 61 and the second vertical pipe 63 are respectively fixed to the top plate 1 of the structure and the water collection well 13 by a support frame.

[0033] Furthermore, in the above technical solution, the inner diameter of the first vertical tube 61 and the second vertical tube 63 is smaller than the inner diameter of the inclined tube 62, and the inner diameters at both ends of the corrugated hose 4 are matched with the inner diameters of the first vertical tube 61 and the inclined tube 62, respectively, and the inner diameter of the corrugated hose 4 gradually increases or decreases.

[0034] Furthermore, in the above technical solution, the lengths of the multiple tie rods 7 increase sequentially along the water flow direction inside the inclined pipe 62, making the angle between the first vertical pipe 61 and the inclined pipe 62 an obtuse angle, and the angle between the second vertical pipe 63 and the inclined pipe 62 also an obtuse angle. That is, after the inclined pipe 62 is installed, it forms a drainage slope of 2%-5%.

[0035] Furthermore, in the above technical solution, the elastic fastener 5 includes a first arm plate 51 and a second arm plate 52 arranged opposite to each other, and the first arm plate 51 and the second arm plate 52 are combined into an adjustable clamp by screws 53. The inner ring of the adjustable clamp is provided with a rubber buffer layer, and the distance between two adjacent adjustable clamps does not exceed 1.5m, allowing the structural top plate 1 to deform and displace ±30mm during construction.

[0036] Furthermore, in the above technical solution, the pull rod 7 is rotatably connected to the first arm plate 51, the top end of the pull rod 7 is engaged with the spring 8, and the top end of the spring 8 is fixedly connected to the top plate 1 of the structure.

[0037] Furthermore, in the above technical solution, the drain 3 is equipped with an easily removable filter screen 2, and the collection well 13 is equipped with a treatment system for purifying rainwater, which includes a primary baffle plate, a secondary sand and gravel filter layer, and a final secondary medium-coarse sand filter layer. The primary baffle plate is located at the output end of the second vertical pipe 63, the secondary sand and gravel filter layer is located at the bottom of the primary baffle plate, and the primary baffle plate and the secondary sand and gravel filter layer are embedded inside the final secondary medium-coarse sand filter layer. The primary baffle plate is made of stainless steel perforated plate with a pore size of 8-10mm; the secondary sand and gravel filter layer has a particle size of 10-20mm and a thickness of 300-400mm; the final secondary medium-coarse sand filter layer has a particle size of 0.5-1.2mm and a thickness of 200-300mm. Rainwater is filtered and impurities are adsorbed through the baffle plate, the secondary sand and gravel filter layer, and the final secondary medium-coarse sand filter layer, thus achieving water purification to a certain extent.

[0038] Furthermore, in the above technical solution, the water collection well 13 is provided with a support 10 made of stainless steel to support the water pump 11, and the bottom of the support 10 is provided with a rubber shock-absorbing pad.

[0039] Furthermore, in the above technical solution, a liquid level sensor 12 is installed inside the water collection well 13 to sense the liquid level height inside the water collection well 13 and feed back the information to the microcontroller 9. An alarm 131 is installed at the connection end of the microcontroller 9.

[0040] Furthermore, in the above technical solution, the input and output terminals of the microcontroller 9 are electrically connected to an A / D converter and a D / A converter, respectively.

When the liquid level reaches the first water level (e.g., 1 / 3 of the well depth), the alarm 131 is controlled to work and start the warning; when the liquid level reaches the second water level (e.g., 2 / 3 of the well depth), the water pump 11 is controlled to work and automatically start drainage.

[0050] Step 2.3, End Connection: The end of the second vertical pipe 63 is connected to the permanent water collection well 13.

[0051] Step 3: Installation of the internal purification system of water collection well 13:

[0052] Step 3.1, Construction of the three-stage filter layer:

[0062] (2) The easily detachable filter screen 2 intercepts debris ≥5mm;

[0063] (3) Rainwater is discharged into the collection well 13 through the conveying pipe 6 at a flow rate of ≥0.3m / s. The inclined pipe 62 can move through the corrugated hose 4 and the spring 8. The middle part of the conveying pipe 6 is made into a soft connection, which makes the two corners more passable and reduces the possibility of blockage.

[0070] (2) When the level sensor 12 detects that the water level has risen to 2 / 3 of the well depth, the water pump 11 is automatically started;

[0071] (3) During the drainage process, the rubber shock-absorbing pads control the vibration transmission rate to ≤15%.
