Problems solved by technology

[0003] At present, the purpose of waterproofing is achieved by firmly bonding the wall bushing to the wall during construction, but in this way, in the later construction and maintenance, the wall bushing will be difficult to disassemble, and some parts of the wall bushing will be damaged. , and it is also difficult to replace. Condensation or deformation of the exterior wall concrete during long-term use will cause gaps in the bonding between the wall sleeve and the wall, and water leakage is still prone to occur

Embodiment 1

[0047] see Figure 1-Figure 4 , a waterproof wall-piercing casing for the exterior wall of a basement, comprising an exterior wall 1 and a flexible waterproof casing 2 pre-embedded inside the exterior wall 1, the middle of the outer wall of the flexible waterproof casing 2 is provided with a water-stop ring 3, flexible and waterproof A flange 11 is fixedly installed on the end of the casing 2 facing the backwater surface, and a mounting cylinder 12 is fixedly installed on the edge of the outer wall of the flange 11 facing the backwater side, and the outer wall of the flange 11 facing the waterfront side is uniformly fixed and installed There are threaded sleeves 13;

[0048] The interior of the flexible waterproof casing 2 is plugged with a wall-piercing pipe 8, and the outer wall of the end of the wall-piercing pipe 8 located at the backwater surface is fixedly equipped with a fixing ring 14, and a locking mechanism connected between the threaded sleeve 13 and the fixing ring...

Embodiment 2

[0054] see figure 1 , figure 2 , image 3 , Figure 4 and Figure 6 , on the basis of Embodiment 1, a left retaining ring 4 and a right retaining ring 5 are respectively fixedly installed on both sides of the inner wall of the flexible waterproof casing 2, and an elastic damping ring is fixedly installed between the left retaining ring 4 and the right retaining ring 5 7 and the elastic sound-insulating ring 6, the elastic vibration-damping ring 7 and the elastic sound-insulating ring 6 are provided with three altogether, wherein the elastic sound-insulating ring 6 is arranged in the middle, and the elastic vibration-damping ring 7 is arranged on both sides of the elastic sound-insulating ring 6, and the elastic vibration-damping ring 7 is used for shock absorption, and the elastic sound insulation ring 6 is used for sound insulation. The left retaining ring 4 is fixedly installed with several left gaskets 9 on the side facing the backwater surface, and the right retaining ...

Embodiment 3

[0060] see Figure 1-Figure 7 , on the basis of Embodiment 1 and Embodiment 2, a method for installing a waterproof wall-penetrating sleeve for the basement exterior wall is proposed, including the following steps:

[0061] Step 1: Select a flexible waterproof casing 2 of appropriate size, and weld the flexible waterproof casing 2 to the fixed steel bar of the outer wall 1;

[0062] Step 2: Place a nail-shaped water bag 29 inside the flexible waterproof casing 2 to temporarily support the flexible waterproof casing 2; fix and install templates 30 at both ends of the flexible waterproof casing 2, and temporarily close the flexible waterproof casing 2;

[0063] Step 3: Pour the wall concrete according to the standard construction requirements and wait for it to solidify;

[0064] Step 4: After the wall concrete is solidified, remove the formwork 30 at both ends of the flexible waterproof casing 2 and take out the nail-shaped water bag 29;

[0065] Step 5: Insert the wall-pierc...

Abstract

The invention relates to the technical field of basement exterior wall waterproofing, and discloses a waterproof wall bushing for a basement exterior wall, which comprises an exterior wall and a flexible waterproof bushing pre-embedded in the exterior wall, a flange is fixedly mounted at one end, facing the downstream surface, of the flexible waterproof bushing, a mounting cylinder is fixedly mounted on the edge of the outer wall of the side, facing the downstream face, of the flange, and threaded sleeves are evenly and fixedly mounted on the outer wall of the side, facing the upstream face, of the flange. A through-wall pipe is inserted into the flexible waterproof bushing in the direction from the downstream face to the upstream face, and bolts in nuts are tightened in the threaded sleeves, so that the through-wall pipe can be fixed in the flexible waterproof bushing, and the through-wall pipe is very convenient to mount and dismount; and the waterproof wall bushing is novel in design, is simple in structure, and has the advantages of being easy to dismount and replace and good in waterproof effect.

Description

technical field [0001] The invention relates to the technical field of waterproofing of basement exterior walls, in particular to a waterproof wall-penetrating sleeve used for basement exterior walls and an installation method thereof. Background technique [0002] During the construction of the basement external wall, the wall-through casing is generally pre-buried in the wall structure, which is suitable for the construction of public and civil building water supply and drainage pipelines, especially for the anti-seepage external wall of the basement, living pools, fire pools, etc. There are special requirements for water stop. [0003] At present, the purpose of waterproofing is achieved by firmly bonding the wall bushing to the wall during construction, but in this way, in the later construction and maintenance, the wall bushing will be difficult to disassemble, and some parts of the wall bushing will be damaged. , It is also difficult to replace. Condensation or deform...
