Description

TECHNICAL FIELD

[0001] The present application relates to the field of building waterproofing, in particular to a multi-level waterproof structure for basement entrance and a construction method thereof. BACKGROUND

[0002] The building basement is prone to water accumulation due to its low terrain. During the flood season or heavy rain, rainwater will flow into the building basement through the building basement entrance, affecting people's normal travel. In related technologies, sandbags are usually stacked at the entrance of the garage when the flood season or heavy rain arrives to prevent the ground water from flowing into the building basement through the basement entrance.

[0003] According to the above related technologies, the inventors believe that the following defects exist: During the rainy season, sand needs to be manually filled into the sandbags, which is cumbersome, and when the sandbags are placed, the basement has already been filled with a lot of rainwater, which is lagging, and therefore needs to be improved. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a multi-level waterproof structure for basement entrance and a construction method thereof, aiming to solve the above problems.

[0005] A multi-level waterproof structure for basement entrance comprises a mounting seat buried in the ground of the basement entrance, a water blocking piece and a driving assembly installed on the mounting seat for blocking rainwater and surface water, and a waterproof layer provided outside the mounting seat. An installation slot for the water blocking piece to slide up and down and a connecting slot for the driving assembly to be installed are formed in the mounting seat. The driving assembly comprises a driving box, a driving block, and a tightening spring for tensioning the driving block. The driving box is filled with water-absorbing material and has an open upper end surface. The driving block is in sliding connection with the inner bottom wall of the mounting seat. One end of the tightening spring is connected to the inner side wall of the connecting slot, and the other end is connected to the driving block. The driving hole for the driving block to pass through is in common communication between the installation slot and the connecting slot. The lower end surface of the water blocking piece and the lower end surface of the driving box are in abutment with the driving block.

[0006] By adopting the above technical solution, when it rains, rainwater enters the driving box and is absorbed by the water-absorbing material. The driving box becomes heavier and exerts a downward pressure on the driving block. The driving block moves after being pressed, thereby lifting the water blocking piece. This achieves multi-level blocking of rainwater and surface water. The driving assembly can automatically respond to changes in water level, causing the water blocking piece to be lifted simultaneously when the water level rises, forming a dynamic sealing barrier and significantly improving the waterproof reliability.

[0007] Optionally, a filter plate for covering the connecting slot is installed on the upper end surface of the mounting seat, and a plurality of filter holes are uniformly formed in the filter plate.

[0008] By adopting the technical scheme, the filter plate can filter rainwater, thereby reducing impurities in the rainwater from entering the connecting groove.

[0009] Optionally, a water storage plate is connected in the connecting groove, and at least one positioning strip is connected to the water storage plate.

[0010] By adopting the technical scheme, the water storage plate can divide the connecting groove into two separated spaces, when the rainwater is less and the water level cannot be higher than the upper end surface of the positioning strip, the rainwater cannot fall into the driving box, thereby the water blocking member cannot be lifted when the rainwater is less, and people can pass through conveniently.

[0011] Optionally, a chamfer is arranged at the edge of the upper end surface of the water blocking member.

[0012] By adopting the technical scheme, the chamfer can form an inclined surface on the upper end surface of the water blocking member, thereby facilitating the smooth passing of pedestrians and non-motor vehicles.

[0013] Optionally, a plurality of water passing holes are formed through the inner side wall of the mounting groove and are in communication with the connecting groove, and the horizontal height of the water passing holes is higher than the upper end surface of the positioning strip.

[0014] By adopting the technical scheme, the rainwater flowing into the mounting groove can enter the connecting groove through the water passing holes, thereby further increasing the rainwater flowing into the connecting groove, and increasing the starting efficiency of the water blocking member.

[0015] Optionally, a drainage box is connected to the lower end surface of the mounting seat, a water filtering hole is formed through the bottom wall of the mounting seat and is in communication with the drainage box, and a drainage pipe is connected to the bottom wall of the drainage box.

[0016] By adopting the technical scheme, the excess rainwater in the mounting seat can enter the drainage box through the water filtering hole, and is drained into an external water collecting well through the drainage pipe at the bottom of the drainage box.

[0017] Optionally, an extrusion plate is arranged at the lower end surface of the water storage plate, a plurality of through holes are uniformly formed through the extrusion plate, support rods are connected to the two sides of the upper end surface of the extrusion plate, two mounting holes are formed through the water storage plate and are used for the support rods to pass through, a limiting hole is formed through the filter plate and is used for the support rods to pass out, an extension rod is hinged to one end of the support rod, a gap slot is formed through the filter plate and is used for the extension rod to be clamped into, and a plurality of water outlet holes are formed through the lower end surface of the driving box.

[0018] By adopting the technical scheme, when the flood season ends, the extrusion plate is driven to move downward by the extension rod, the extrusion plate extrudes the water absorbing material in the driving box, thereby the water is rapidly drained from the water absorbing material.

[0019] Optionally, the opposite inner side walls of the yielding slot are connected with elastic pads for abutting against the extension rod.

[0020] By adopting the above technical scheme, the elastic pad can stably abut against the extension rod, effectively prevents loosening of the extension rod caused by vibration or external force, enhances the stability of the mechanical structure, ensures the reliability of the system in long-term use, and reduces the maintenance requirement.

[0021] Optionally, the waterproof layer comprises a self-repairing layer, the self-repairing layer is internally filled with a repairing agent, and the opposite sides of the self-repairing layer are connected with elastic reinforcing layers.

[0022] By adopting the above technical scheme, by internally filling the repairing agent and the elastic reinforcing layers, the self-repairing function of the waterproof layer is realized, when the waterproof layer is slightly damaged, the repairing agent can automatically fill the cracks, the elastic reinforcing layers themselves have good elasticity, and the risk of cracks caused by structural deformation or construction errors is compensated, the service life of the waterproof system is prolonged, the maintenance cost is reduced, and the durability of the overall waterproof performance is improved.

[0023] The application also provides a construction method of the multi-stage waterproof structure of the basement entrance. Step S1: clean the surrounding area of the basement entrance to ensure that the construction surface is flat; Step S2: excavate a slot in the ground of the basement entrance, and bury the mounting seat in the ground to ensure that the mounting seat is horizontal and firmly fixed; Step S3: install the waterproof layer outside the mounting seat, and ensure that the waterproof layer is completely covered; Step S4: perform a functional test, inject water into the mounting seat area, check whether the water-blocking part can automatically rise to form a waterproof barrier, and check whether the drainage system is working normally; Step S5: adjust according to the test result, and perform final acceptance after ensuring that the system is working normally.

[0024] In summary, the application has at least one of the following beneficial technical effects: 1. When it rains, rainwater enters the drive box and is absorbed by the water-absorbing material, the drive box becomes heavier and exerts a downward force on the drive block, the drive block moves after being pressed, thereby lifting the water-blocking part, achieving multi-level blocking of rainwater and surface water, the drive assembly can automatically respond to changes in water level, so that the water-blocking part is lifted synchronously when the water level rises, forming a dynamic sealing barrier, and the waterproof reliability is significantly improved.

[0025] 2. The water storage plate can separate the connecting groove into two separate spaces, when there is little rain, the water level cannot be higher than the upper end surface of the positioning strip, and rainwater cannot fall into the drive box, so that the water-blocking part does not rise when there is little rain, facilitating people to pass through.

[0026] 3、When the flood season ends, the extrusion plate is driven to move down by the extension rod, and the extrusion plate extrudes the water-absorbing material in the drive box, so that the water is quickly discharged from the water-absorbing material.

[0027] 4、The elastic pad can stably abut against the extension rod, effectively prevents loosening of the extension rod caused by vibration or external force, enhances the stability of the mechanical structure, ensures the reliability of the system in long-term use, and reduces the maintenance requirement.

[0028] 5、By filling the repair agent and the elastic reinforcing layer, the self-repairing function of the waterproof layer is realized, when the waterproof layer has a small damage, the repair agent can automatically fill the crack, the elastic reinforcing layer itself has good elasticity, which makes up for the crack risk caused by structural deformation or construction error, prolongs the service life of the waterproof system, reduces the maintenance cost, and improves the durability of the overall waterproof performance.

[0039] Referring to Figure 2 and Figure 3 , the installation groove 11 for slidingly accommodating the water blocking piece 2 up and down and the connecting groove 12 for accommodating the driving assembly 3 are formed in the installation seat 1. The driving assembly 3 includes the driving box 31, the driving block 32, and the fastening spring 33 for tensioning the driving block 32. The driving box 31 is filled with water-absorbing material and has an open upper end surface, and the water-absorbing material can be a sponge.

When it rains, rainwater enters the driving box 31 and is absorbed by the water-absorbing material, the driving box 31 becomes heavy and exerts a downward pressure on the driving block 32, the driving block 32 moves after being pressed, thereby lifting the water blocking piece 2, achieving multi-level blocking of rainwater and surface water, and the driving assembly 3 can automatically respond to changes in water level, so that the water blocking piece 2 is lifted synchronously when the water level rises, forming a dynamic sealing barrier and significantly improving the waterproof reliability.

[0040] Referring to Figure 2 and Figure 3The upper end surface of the mounting base 1 is provided with a filter plate 5 for covering the connecting groove 12, and a plurality of filter holes are uniformly arranged on the filter plate 5. The filter plate 5 can filter rainwater, thereby reducing impurities in the rainwater from entering the connecting groove 12.

[0041] With reference to Figure 2 and Figure 3 , the connecting groove 12 is fixedly connected with a water storage plate 6, and the water storage plate 6 is fixedly connected with three positioning strips 61. The upper end surface of each positioning strip 61 is spaced apart along the length direction of the positioning strip 61 and is provided with five water permeable holes 611. The water storage plate 6 can divide the connecting groove 12 into two separate spaces. When the amount of rainwater is small, the water level cannot be higher than the upper end surface of the positioning strip 61, and the rainwater cannot fall into the driving box 31, so that the water blocking member 2 does not rise when the amount of rainwater is small, thereby facilitating the passage of people and non-motor vehicles.

[0042] With reference to Figure 2 and Figure 3 , the upper end surface of the water blocking member 2 is provided with a chamfer.

The excess rainwater in the mounting base 1 enters the drainage box 7 through the water filtering hole 13 and is discharged into an external water collecting well through the drainage pipe 71 at the bottom of the drainage box 7.

[0044] With reference to Figure 2 , Figure 3 and Figure 4The lower end surface of the water storage plate 6 is provided with a pressing plate 8, and a plurality of through holes are uniformly arranged on the pressing plate 8.

When the flood season ends, the extension rod 82 drives the pressing plate 8 to move downward, and the pressing plate 8 extrudes the water-absorbing material in the driving box 31, so that the water is quickly discharged from the water-absorbing material. The elastic pad 521 can stably abut against the extension rod 82, effectively preventing the extension rod 82 from loosening due to vibration or external force, enhancing the stability of the mechanical structure, ensuring the reliability of the system in long-term use, and reducing the maintenance requirement.

[0045] With reference to Figure 1 and Figure 5 , the outer side of the mounting seat 1 is provided with a waterproof layer 4, and the mounting seat 1 is connected with the external concrete through the waterproof layer 4.

By filling the repairing agent and the elastic reinforcing layer 42 inside, the self-repairing function of the waterproof layer 4 is realized. When the waterproof layer 4 is slightly damaged, the repairing agent can automatically fill the cracks, and the elastic reinforcing layer 42 itself has good elasticity, which can compensate for the crack risk caused by structural deformation or construction error, prolong the service life of the waterproof system, reduce the maintenance cost, and improve the durability of the overall waterproof performance.
