Description

Technical Field

[0001] The present application relates to the technical field of construction engineering, and in particular to a basement through-the-wall pipe waterproof structure and a construction method. Background Art

[0002] With the continuous development of my country's construction industry, more and more new materials and new technologies have been widely used in the field of construction engineering. While bringing better results, they also have higher requirements for construction. For example, the waterproof structure of the basement wall pipe has put forward new requirements for the waterproof performance and service life of the waterproof structure.

[0003] In the related art, the traditional basement wall-penetrating pipe waterproofing structure usually uses a steel pipe sleeve to seal and waterproof the wall-penetrating water pipe. A wing ring is fixedly connected to the outer circumference of the steel pipe sleeve, and the wing ring is fixedly connected to the wall by bolts. A retaining ring is integrally formed on the inner circumference of the steel pipe sleeve. A certain sealing effect is achieved by arranging a sealing rubber ring, a flexible sealing material and a sealing paste on the retaining ring.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the soil layer outside the basement is moist all year round. When the bolts are in the moist soil layer for a long time, the bolts are prone to rust and loosen. After the bolts are loosened, there is a certain possibility of water seepage in the steel pipe sleeve. Summary of the invention

[0005] In order to improve the waterproof performance of the waterproof structure, the present application provides a basement wall-penetrating pipe waterproof structure and a construction method.

[0006] The present application provides a basement wall-penetrating pipe waterproof structure adopts the following technical solution:

[0007] A basement wall-penetrating pipe waterproof structure comprises an outer wall body and a wall-penetrating pipe penetrated through the outer wall body, a mounting plate is embedded in the outer wall body, a circular hole is formed on the outer wall body, a through hole is formed on the side surface of the mounting plate located in the circular hole, a water-expandable sealing ring is fixedly connected to the inner side wall of the through hole, a fixing sleeve is fixedly sleeved on the wall-penetrating pipe, the fixing sleeve passes through the water-expandable sealing ring and slidably cooperates with the water-expandable sealing ring, and a locking component for locking the fixing sleeve is provided on the inner side wall of the through hole.

[0008] By adopting the above technical scheme, the operator buries the installation plate into the outer wall body simultaneously when constructing the outer wall body. When the operator installs the through-wall pipe, the operator places the fixed sleeve in the through-hole. At this time, the inner surface of the water-expandable sealing ring fits with the outer surface of the fixed sleeve. Then, the operator uses the locking assembly to lock the position of the fixed sleeve, thereby fixing the position of the fixed sleeve and the through-wall pipe. On the one hand, the setting of the locking assembly can improve the stability of the installation of the fixed sleeve and the through-wall pipe. On the other hand, the locking assembly is set on the inner wall of the through-hole, which is conducive to avoiding the influence of the external soil layer on the locking assembly, thereby ensuring the service life of the locking assembly, and then improving the waterproof performance and durability of the basement through-wall pipe waterproof structure.

[0009] Preferably, the locking assembly is provided with two groups, and the two groups of locking assemblies are symmetrically arranged about the axis of the through hole, and the locking assembly includes a positioning rod slidably penetrated on the inner side wall of the through hole, a moving rod slidably penetrated on the positioning rod, and an arc-shaped plate fixedly connected to the moving rod away from the end of the positioning rod, a positioning groove for slidingly cooperating with the positioning rod is provided in the mounting plate, a connecting hole for passing the moving rod is provided on the inner end surface of the positioning groove, the arc plate abuts against the outer peripheral surface of the fixed sleeve, and a first spring is sleeved on the moving rod, one end of the first spring is fixedly connected to the positioning rod, and the other end of the first spring is fixedly connected to the arc-shaped plate.

[0010] By adopting the above technical solution, the operator first presses the arc plate, and the operator makes the moving rod on the arc plate enter the positioning rod. At this time, the first spring is in a compressed state, and then the operator installs the fixed sleeve and the wall-penetrating pipe. When the fixed sleeve is located in the water-expandable sealing ring, the arc plate is pressed against the fixed sleeve under the action of the first spring, thereby locking the position of the fixed sleeve and the wall-penetrating pipe.

[0011] Preferably, a sealing strip is installed on the arc plate, an arc groove is provided on the side of the arc plate close to the fixed sleeve, an annular groove is provided on the outer peripheral surface of the fixed sleeve, one side of the sealing strip is fixedly connected to the inner wall of the arc groove, and the other side of the sealing strip abuts against the inner wall of the annular groove.

[0012] By adopting the above technical scheme, the setting of the arc groove is conducive to the installation of the sealing strip. The cooperation between the sealing strip and the annular groove is conducive to positioning the position of the fixed sleeve on the one hand, and on the other hand, the cooperation between the sealing strip and the annular groove is conducive to preventing groundwater from penetrating into the room through the gap between the fixed sleeve and the water-swellable sealing ring, thereby further enhancing the waterproof performance between the fixed sleeve and the mounting plate.

[0014] By adopting the above technical solution, when the end of the sealing strip away from the arc plate is pressed into the annular groove, the sealing teeth at both ends of the sealing strip are inserted into the sealing groove of the connecting block. The cooperation between the sealing teeth and the sealing groove is beneficial to improving the stability of the connection between the sealing strip and the connecting block, and also increases the waterproof performance between the sealing strip and the connecting block.

[0016] By adopting the above technical solution, when the sealing strip is pressed into the annular groove, the operator pushes the driving rod toward the positioning rod, and the driving rod pushes the positioning rod to move through the inclined surface. The driving rod causes the positioning rod to move toward the arc plate. The positioning rod shortens the length of the first spring, thereby increasing the pressure of the first spring on the arc plate, thereby enhancing the sealing between the sealing strip and the fixed sleeve, and also improving the stability of the fixed sleeve. The setting of the reset assembly is conducive to resetting the driving rod, thereby facilitating the driving rod to extend out of the mounting plate.

[0017] Preferably, the reset assembly includes a fixing plate fixedly connected to the driving rod and a second spring fixedly connected to the fixing plate, a reset groove for slidingly cooperating with the fixing plate is provided on the inner side wall of the guide groove, the end of the second spring away from the fixing plate is fixedly connected to the inner end surface of the reset groove, and a slot for plugging and cooperating with the inclined surface of the positioning rod is provided on the driving rod.

[0018] By adopting the above technical solution, the operator can first use the inclined surface of the positioning rod to insert it into the slot of the driving rod, thereby locking the position of the driving rod. At this time, the driving rod is completely inserted into the mounting plate, and the second spring is in a compressed state, which makes it convenient for the operator to transport the mounting plate. When the operator needs to install the fixed sleeve, the operator pulls down the arc plate, and the first spring drives the positioning rod to disengage from the slot. At this time, the fixing block drives the driving rod to reset under the elastic force of the second spring.

[0019] Preferably, the mounting plate is provided with sealing rings on both sides of the circular hole, the sealing ring is sleeved on the wall-penetrating pipe and slidingly cooperates with the wall-penetrating pipe, a threaded ring is fixedly connected to the sealing ring, threaded grooves for threaded cooperation with the threaded ring are provided on both sides of the mounting plate, and the sealing ring abuts against the driving rod.

[0020] By adopting the above technical solution, the operator first sets the sealing ring on the wall-penetrating pipe, and then aligns the threaded ring on the sealing ring with the threaded groove. The operator rotates the sealing ring, and the sealing ring moves toward the fixed sleeve. The setting of the sealing ring can, on the one hand, limit the position of the fixed sleeve and strengthen the connection strength between the fixed sleeve and the mounting plate; on the other hand, the sealing ring can push the driving rod to move, thereby further improving the waterproof performance of the waterproof structure.

[0021] Preferably, a rubber ring is fixedly connected to the outer circumference of the sealing ring, a limiting ring is fixedly connected to the rubber ring, a limiting groove for accommodating the limiting ring is opened on the outer circumference of the sealing ring, and a waterproof ring is fixedly connected to the side of the sealing ring close to the fixed sleeve.

[0022] By adopting the above technical solution, the cooperation between the limiting ring and the limiting groove makes it convenient for operators to install the rubber ring.
