Description

Technical Field

[0001] This invention relates to the field of waterproofing devices, specifically a curtain-type waterproofing device for foundation pit slopes during the rainy season. Background Technology

[0002] Slope protection of foundation pits is a very important process in the construction of houses. Foundation pits are earthen pits excavated at the foundation design location according to the foundation elevation and foundation plane dimensions. After the foundation pit is excavated, the slope is prone to collapse due to the effect of earth pressure. It is necessary to support and slope the foundation pit slope. Traditional foundation pit slope treatment will prevent soil loss by laying waterproof membranes, nylon bags, plastic sheets, etc., and use anchor cables to reinforce the soil.

[0003] However, the current method of waterproofing by manually laying plastic sheeting presents several safety risks, especially when working in the rain, as the edges of the pit are slippery and prone to falls. Manual laying of plastic sheeting typically involves using weights to prevent it from being blown away, often requiring workers to move nearby stones or construction materials for weight, which takes a long time. Furthermore, improper manual weighting can lead to insufficient weight, causing the plastic sheeting to be blown away by strong winds and compromising its waterproofing effectiveness. Summary of the Invention

[0004] To address the problems in the existing technology, the present invention provides a curtain-type waterproofing device for foundation pit slopes during the rainy season.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a curtain-type waterproofing device for foundation pit slope during the rainy season, including a base plate, a fixing mechanism installed on the base plate, an adjusting mechanism installed on the fixing mechanism, a protective mechanism installed on the fixing mechanism, a counterweight mechanism installed on the protective mechanism, and a storage mechanism installed on the protective mechanism;

[0006] The fixing mechanism includes two support tubes, and the two ends of the base plate are fixedly connected to the support tubes. The two support tubes are fixedly connected to the fixing hooks. The adjusting mechanism includes a connecting block, the end of the fixing hook is fixedly connected to the connecting block, and the end of the connecting block is fixedly connected to the mounting plate. The mounting plate is provided with a pull rope.

[0007] Specifically, the adjustment mechanism further includes a first screw, which is fixedly connected to the mounting plate. A lower pressure plate located inside the mounting plate is slidably connected to the first screw. A first nut is threaded to the top of the first screw, and a pull rope is held between the lower pressure plate and the mounting plate.

[0008] Specifically, the protective mechanism includes a hook, a hook slidably connected to the pull rope, and a waterproof cloth fixedly connected to the end of the hook.

[0009] Specifically, the pull hook is provided in multiple parts, and the cross-section of the pull hook is in the shape of an "S" shape.

[0010] Specifically, the counterweight mechanism includes a counterweight rod, and the bottom end of the waterproof cloth is slidably connected to the counterweight rod.

[0011] The counterweight mechanism also includes a limiting plate, one end of the counterweight rod is fixedly connected to the limiting plate, and the other end of the counterweight rod is threadedly connected to a second nut.

[0012] Specifically, the storage mechanism includes a first storage plate, which is fixedly connected to the side wall of the waterproof fabric. A rotating rod is rotatably connected to the first storage plate, and a second storage plate is rotatably connected to the rotating rod. The height of the second storage plate is greater than the thickness of the waterproof fabric.

[0013] Specifically, the storage mechanism further includes a first fixing plate, the side wall of the second storage plate is fixedly connected to the first fixing plate, the first fixing plate has a slot, the side wall of the first storage plate is fixedly connected to a second fixing plate that cooperates with the first fixing plate, the second fixing plate is threadedly connected to a second screw, the top end of the second screw is fixedly connected to a card plate that cooperates with the slot, and the cross-section of the second screw and the card plate is a "T" shaped structure.

[0014] The beneficial effects of this invention are:

[0015] (1) The present invention provides a curtain-type waterproofing device for foundation pit slopes during the rainy season. A fixing mechanism is installed on the base plate. The waterproofing material can be installed through the fixing mechanism. Workers do not need to work at the edge of the foundation pit for a long time, which also ensures the safety of the working environment and has certain economic benefits. That is, when the foundation pit needs to be waterproofed, multiple scaffolding pipes are installed 1m away from the edge of the foundation pit. The spacing between the multiple scaffolding pipes is 1.2m and they are inserted into the ground through the base plate. A 30cm*30cm drainage ditch is set at the edge of the bottom of the pit. The ditch is filled with large-particle gravel. The drainage ditch is used to divert rainwater to the collection pit for pumping. Since there are fixed hooks fixedly connected to the scaffolding pipes, and a water retaining wall is built on the scaffolding pipes, the side of the water retaining wall is 30cm*30cm. The end of the fixed hook is equipped with a pull rope through the installation plate. Therefore, the waterproofing material can be installed by pulling the rope. Workers do not need to work at the edge of the foundation pit for a long time, which also ensures the safety of the working environment and has certain economic benefits.

[0016] (2) The curtain-type waterproofing device for foundation pit slope in the rainy season described in this invention has an adjustment mechanism installed on the fixing mechanism and a protective mechanism installed on the adjustment mechanism. The protective mechanism can be installed and adjusted more quickly through the adjustment mechanism, and no manual weight is required, which greatly shortens the traditional manual laying operation time and avoids the foundation pit slope from being affected by rainwater. That is, the waterproof cloth can be fixedly connected to the end of the sliding hook on the pull rope, and the foundation pit can be protected by the waterproof cloth, and no manual weight is required, which greatly shortens the traditional manual laying operation time and avoids the foundation pit slope from being affected by rainwater. There are multiple hooks, which can enhance the extensibility of the waterproof cloth. When the pull rope is used for a long time, the pull rope will bend, so the stability of the waterproof cloth cannot be guaranteed. At this time, one end of the pull rope can be pulled on the installation plate to straighten the pull rope, and then the first nut can be rotated to make the lower pressure plate squeeze the pull rope. The pull rope can be installed and adjusted more quickly by rotating the first nut.

[0017] (3) The curtain-type waterproofing device for foundation pit slopes during the rainy season described in this invention has a counterweight mechanism installed on the protective mechanism. The counterweight mechanism can weigh down the protective mechanism, making it less susceptible to being blown away by the wind and preventing the foundation pit from being affected by rainwater, thus achieving a better waterproofing effect. Specifically, a counterweight rod is slidably connected to the bottom end of the waterproof cloth. The counterweight rod weighs down the waterproof cloth, making it less susceptible to being blown away by the wind and preventing the foundation pit from being affected by rainwater, thus achieving a better waterproofing effect. Since one end of the counterweight rod is fixedly connected to a limiting plate and the other end of the counterweight rod is threadedly connected to a second nut, the waterproof cloth can be limited under the cooperation of the limiting plate and the second nut, ensuring the stability of the waterproof cloth. When the waterproof cloth is not in use and is being stored, the counterweight rod can be removed from the waterproof cloth by rotating the second nut, thus allowing the waterproof cloth to be stored and preventing it from being exposed to direct sunlight, which would reduce its durability.

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1-10 As shown, the present invention provides a curtain-type waterproofing device for foundation pit slopes during the rainy season, comprising a base plate 1, a fixing mechanism 2 installed on the base plate 1, an adjusting mechanism 3 installed on the fixing mechanism 2, a protective mechanism 4 installed on the fixing mechanism 2, a counterweight mechanism 5 installed on the protective mechanism 4, and a storage mechanism 6 installed on the protective mechanism 4.

[0032] The fixing mechanism 2 includes two support tubes 201, with the support tubes 201 fixedly connected to both ends of the base plate 1. Fixing hooks 202 are fixedly connected to the two support tubes 201. The adjusting mechanism 3 includes a connecting block 303, with the end of the fixing hook 202 fixedly connected to the connecting block 303. An installation plate 301 is fixedly connected to the end of the connecting block 303. A pull rope 302 is provided on the installation plate 301. When waterproofing the foundation pit is required, multiple support tubes 201 are installed 1m from the edge of the foundation pit, with a spacing of 1.2m between the multiple support tubes 201, and inserted into the ground through the base plate 1. A 30cm*30cm drainage ditch is set at the bottom edge of the pit, filled with large-particle gravel. The drainage ditch is used to divert rainwater to a collection pit for pumping. Since a fixing hook 202 is fixedly connected to the scaffolding pipe 201, and a water retaining wall is built on the scaffolding pipe 201, the side of the water retaining wall is 30cm*30cm. The end of the fixing hook 202 is connected to a pull rope 302 through the mounting plate 301. Therefore, the waterproof material can be installed by pulling the rope 302. Workers do not need to work at the edge of the pit for a long time, which ensures the safety of the working environment and also has certain economic benefits.

[0033] Specifically, the adjusting mechanism 3 further includes a first screw 305, which is fixedly connected to the mounting plate 301. A lower pressure plate 304 located inside the mounting plate 301 is slidably connected to the first screw 305. A first nut 306 is threadedly connected to the top of the first screw 305. A pull rope 302 is held between the lower pressure plate 304 and the mounting plate 301. The protective mechanism 4 includes a hook 401, which is slidably connected to the pull rope 302. A waterproof cloth 402 is fixedly connected to the end of the hook 401. Multiple hooks 401 are provided, and the cross-section of the hook 401 is "S" shaped. By sliding the hook 401 on the pull rope 302, the hook 401... The end of 01 is fixedly connected to a waterproof cloth 402, which can protect the foundation pit without the need for manual weight-bearing, greatly shortening the traditional manual laying operation time and preventing the foundation pit slope from being affected by rainwater. Multiple hooks 401 are provided to enhance the extensibility of the waterproof cloth 402. When the pull rope 302 has been used for a long time, the pull rope 302 will bend, so the stability of the waterproof cloth 402 cannot be guaranteed. At this time, one end of the pull rope 302 can be pulled on the mounting plate 301 to straighten the pull rope 302. Then, the first nut 306 is rotated to make the lower pressure plate 304 squeeze the pull rope 302. By rotating the first nut 306, the pull rope 302 can be installed and adjusted more quickly.

[0034] Specifically, the counterweight mechanism 5 includes a counterweight rod 501. The bottom end of the waterproof fabric 402 is slidably connected to the counterweight rod 501. One end of the counterweight rod 501 is fixedly connected to a limit plate 503, and the other end of the counterweight rod 501 is threadedly connected to a second nut 502. The counterweight rod 501 presses down on the waterproof fabric 402, making it less susceptible to being blown away by the wind and preventing localized rainwater damage to the foundation pit, thus providing better waterproofing. One end of the counterweight rod 501 is fixedly connected to a limiting plate 503, and the other end of the counterweight rod 501 is threadedly connected to a second nut 502. With the cooperation of the limiting plate 503 and the second nut 502, the waterproof cloth 402 can be limited to ensure its stability. When the waterproof cloth 402 is not in use and is to be stored, the counterweight rod 501 can be removed from the waterproof cloth 402 by turning the second nut 502. Therefore, the waterproof cloth 402 can be stored to prevent it from being exposed to direct sunlight and reducing its durability.

[0035] Specifically, the storage mechanism 6 includes a first storage plate 601, which is fixedly connected to the side wall of the waterproof fabric 402. A rotating rod 602 is rotatably connected to the first storage plate 601, and a second storage plate 603 is rotatably connected to the rotating rod 602. The height of the second storage plate 603 is greater than the thickness of the waterproof fabric 402. A first fixing plate 604 is fixedly connected to the side wall of the second storage plate 603. A slot 605 is provided on the first fixing plate 604. A second fixing plate 606, which cooperates with the first fixing plate 604, is fixedly connected to the side wall of the first storage plate 601. A second screw 607 is threadedly connected to the second fixing plate 606. A locking plate 608, which cooperates with the slot 605, is fixedly connected to the top of the second screw 607. The cross-sections of the second screw 607 and the locking plate 608 are at an angle of [insert cross-section here]. The "T"-shaped structure allows the waterproof fabric 402 to be folded and slid onto the first storage plate 601 by rotating the second storage plate 603. The second storage plate 603 is then rotated, placing it on top of the waterproof fabric 402. The first and second storage plates 601 and 603 together compress and store the waterproof fabric 402. The second screw 607 can then be rotated to remove it from the second fixing plate 606 and inserted into the slot 605. Rotating the second screw 607 creates a threaded connection between it and the second fixing plate 606, simultaneously creating a cross structure between the locking plate 608 and the slot 605. Therefore, the second screw 607 securely stores the waterproof fabric 402 between the first and second storage plates 601 and 603, making the operation simple and convenient.

[0036] When this invention is in use, if waterproofing of the foundation pit is required, multiple support pipes 201 are installed 1m from the edge of the foundation pit, with a spacing of 1m between the multiple support pipes 201.The scaffold pipe is 2m deep and inserted into the ground through the base plate 1. A 30cm*30cm drainage ditch is set at the edge of the pit bottom, filled with large-particle gravel. The drainage ditch is used to divert rainwater to a collection pit for pumping. A fixing hook 202 is fixedly connected to the scaffold pipe 201, and a water-retaining wall is built on the scaffold pipe 201. The side of the water-retaining wall is 30cm*30cm. A pull rope 302 is installed at the end of the fixing hook 202 through the mounting plate 301. Therefore, the waterproof material can be installed through the pull rope 302. Workers do not need to work at the edge of the pit for a long time, ensuring the safety of the working environment and also having certain economic benefits. A sliding hook 401 is attached to the pull rope 302, and a waterproof cloth 402 is fixedly connected to the end of the hook 401, which can be used to install waterproof material. The waterproof fabric 402 protects the foundation pit without requiring manual weighting, greatly shortening the traditional manual laying time and preventing the foundation pit slope from being affected by rainwater. Multiple hooks 401 enhance the extensibility of the waterproof fabric 402. When the pull rope 302 has been used for a long time, it may bend, compromising the stability of the waterproof fabric 402. To straighten it, one end of the pull rope 302 can be pulled on the mounting plate 301, and then the first nut 306 can be rotated to compress the pull rope 302 with the lower pressure plate 304. Rotating the first nut 306 allows for faster installation and adjustment of the pull rope 302. A counterweight rod 501 is slidably connected to the bottom of the waterproof fabric 402, providing support for the waterproof fabric 402. The counterweight 501 prevents the waterproof fabric 402 from being blown away by the wind, thus avoiding localized rainwater damage to the foundation pit and providing better waterproofing. One end of the counterweight 501 is fixedly connected to a limiting plate 503, and the other end is threaded with a second nut 502. The combination of the limiting plate 503 and the second nut 502 effectively limits the position of the waterproof fabric 402, ensuring its stability. When the waterproof fabric 402 is not in use and needs to be stored, the counterweight 501 can be removed by rotating the second nut 502, allowing for proper storage and preventing direct sunlight exposure that could reduce its durability. The waterproof fabric 402 can also be folded by rotating the second storage plate 603. The first storage plate 601 is slidably stacked on top of the second storage plate 603. The second storage plate 603 is then rotated, placing it on top of the waterproof fabric 402. The first and second storage plates 601 and 603 together compress and store the waterproof fabric 402. The second screw 607 can then be rotated to remove it from the second fixing plate 606. The second screw 607 is then inserted into the slot 605 and rotated to thread it onto the second fixing plate 606. Simultaneously, the slot 608 and the clamping plate 608 form a cross structure, thus securing the waterproof fabric 402 between the first and second storage plates 601 and 603 using the second screw 607. The operation is simple and convenient.
