Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically relating to a method for waterproofing basement exterior walls. Background Technology

[0002] With urban development, the development and utilization of urban underground space has become a global trend. Because basements are underground, they are easily affected by the geographical environment, readily absorbing surrounding moisture and humidity, leading to dampness and mold, thus affecting their usability.

[0003] The common practice is to attach waterproof membrane to the exterior walls of the basement, with several membranes spliced ​​and glued together. In this existing technology, to save costs, adjacent membranes are spliced ​​together sequentially. Over time, this can cause the gaps at the joints to widen, and the membranes may peel up or detach at the seams, reducing their waterproofing effectiveness. Summary of the Invention

[0004] The purpose of this invention is to solve the aforementioned technical problems existing in the prior art and to provide a method for waterproofing basement exterior walls. After the basement exterior walls are constructed, a foundation pit is excavated on the outside of the basement exterior walls, and a permanent protective wall is built on the outside of the basement exterior walls. The permanent protective wall serves to reinforce the basement exterior walls and also provides waterproofing and moisture protection for the bottom of the basement exterior walls. After leveling and cleaning the basement exterior wall surface, a primer is applied. The application of the primer increases the adhesion between the waterproof membrane and the basement exterior wall surface, improving the bonding strength of the waterproof membrane and simultaneously protecting the basement exterior walls. The exterior wall surface is leveled and cleaned to prevent unevenness during the application of the waterproof membrane, which could lead to hollow areas, air bubbles, and reduced adhesion strength. The waterproof membrane is then laid using a membrane laying device, improving the accuracy of the application. Simultaneously, the head of the rear waterproof membrane is pressed tightly against the tail of the front waterproof membrane, ensuring close contact between adjacent membranes and preventing enlarged seams that could reduce waterproofing effectiveness. After the waterproof membrane is applied, a lightweight aggregate waterproof protective wall panel is fixed to its outer side. Finally, soil is backfilled between the foundation pit and the basement exterior wall to complete the construction.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] The construction method for waterproofing basement exterior walls includes the following steps:

[0007] a. Pre-construction preparation

[0008] First, a foundation pit is set up outside the basement. A permanent protective wall is built on the outside of the basement. The height of the permanent protective wall is 100mm. After the wall is poured, it is cured.

[0009] b. Application of primer

[0010] Level and clean the exterior walls of the basement, and apply a primer after cleaning.

[0011] c. Laying of the roll waterproofing layer

[0012] After the primer is applied, the waterproof membrane is laid using a membrane laying device. For the basement exterior wall that needs to be constructed, the slide rail is first fixed to the bottom of the pit along the corresponding permanent protective wall. The bottom of the membrane laying device is then inserted into the slide rail, and the membrane is laid piece by piece on the basement exterior wall using the membrane laying device, so that the head of the waterproof membrane on the back side is pressed tightly against the tail of the waterproof membrane on the front side.

[0013] d. Installation of lightweight aggregate waterproof protective wall panels

[0014] Select appropriate lightweight aggregate waterproof protective wall panels according to the dimensions of the basement exterior walls, and fix the lightweight aggregate waterproof protective wall panels to the outside of the roll waterproof layer.

[0015] e. Complete construction

[0016] After the lightweight aggregate waterproof protective wall panels are installed, backfill soil between the basement exterior wall and the foundation pit to complete the construction.

[0017] Furthermore, in step c, during the installation of the roll waterproofing layer, a folded edge is reserved on the top surface of the permanent protective wall. After the roll waterproofing layer on the basement exterior wall is installed, the folded edge is folded upwards and adhered to the bottom of the roll waterproofing layer. By reserving a section of the roll waterproofing layer as a folded edge on the top surface of the permanent protective wall during installation, and then folding the folded edge upwards and adhering it to the bottom of the roll waterproofing layer after it is adhered to the basement exterior wall, the waterproofing effect of the roll waterproofing layer is enhanced.

[0018] Furthermore, a clamping strip is fixed at the point where the flange meets the waterproof membrane. The clamping strip not only secures the flange and increases the connection strength between the flange and the waterproof membrane, but also improves the sealing effect between the flange and the waterproof membrane.

[0019] Furthermore, in step c, the slide rail is detachably connected to the bottom of the pit via a connector. The top surface of the slide rail has a groove, and threaded connection holes are evenly spaced at the end of the top surface near the connector. The connector is screwed into the threaded connection holes with fastening screws, thereby installing the slide rail on the bottom of the pit. The threaded connection holes on the slide rail, the connector, and the fastening screws that fix the slide rail in the pit simultaneously achieve detachability. When laying the slide rail on the exterior walls of each basement, it can be disassembled and installed at the corresponding basement exterior wall pit, enabling reuse and reducing construction costs.

[0020] Furthermore, the connector includes Z-shaped brackets and fixing strips. Several Z-shaped brackets are arranged corresponding to the connecting holes. One end of the top of the Z-shaped bracket has a stepped hole that communicates with the connecting hole. The fastening screw is screwed into the connecting hole through the stepped hole, so that the top of the Z-shaped bracket is pressed against the top surface of the slide rail. The fixing strip is pressed against the other end of the bottom of the Z-shaped bracket and is fixed to the bottom surface of the pit by fastening screws. Several Z-shaped brackets are simultaneously fixed to the base by a fixing strip, and the stepped hole is provided so that the fastening screw is located in the stepped hole, preventing the fastening screw from protruding.

[0021] Furthermore, the roll material laying device includes an adjusting frame, an adjusting seat, a laying component, and a clamping component. The bottom of the adjusting frame has a slider that is slidably connected within a groove. The adjusting seat is slidably connected to the adjusting frame. The laying component is movably connected to the adjusting seat. The clamping component is fixedly connected to the bottom of the adjusting seat. The adjusting seat controls the laying component to lay the roll waterproofing layer, and the clamping component and laying component press the roll waterproofing layer together. The adjusting frame controls the raising and lowering of the adjusting seat, which in turn drives the clamping component and laying component to rise and fall synchronously. The laying component automatically delivers the roll waterproofing layer and adheres it to the basement exterior wall. The clamping component presses the roll waterproofing layer adhered to the basement exterior wall, increasing the adhesion strength of the roll waterproofing layer.

[0022] Furthermore, each inner wall of one side of the adjusting frame is provided with a groove, within which a lead screw is rotatably connected. An adjusting block is provided on one side of the adjusting seat, positioned within the groove, with the lead screw passing through it. A lead screw motor is located at the top of the adjusting frame, controlling the rotation of the lead screw, thereby raising and lowering the adjusting block. The inner wall of the other side of the adjusting frame is provided with a sliding groove, and a sliding block is provided on the other side of the adjusting seat, slidably connected within the sliding groove. The lead screw motor controls the rotation of the lead screw, thereby causing the adjusting seat to slide and adjust along the groove via the adjusting block. The slider and sliding groove serve as a guide for the adjusting seat's sliding adjustment along the groove via the sliding block.

[0023] Furthermore, the laying assembly includes an adjusting track, a laying frame, a conveying roller, and a pressing roller. The adjusting track is fixedly connected to an adjusting seat and has an adjusting groove. A second lead screw is rotatably connected inside the adjusting groove. The bottom of the laying frame near the adjusting seat has an adjusting part located inside the adjusting groove. The second lead screw passes through the adjusting part. The adjusting seat is connected to a second lead screw motor, which controls the rotation of the second lead screw to drive the adjusting part to slide along the adjusting groove. Support columns are fixedly connected to both ends of the top surface of the laying frame. A conveying roller is rotatably connected between the two support columns. The waterproof membrane is fitted over the outside of the conveying roller. A drive motor is located on one side of the support column. The drive motor controls the rotation of the conveying roller, thereby controlling the automatic delivery of the waterproof membrane. A pressing roller is rotatably connected to the other end of the bottom of the laying frame. The pressing roller presses the waterproof membrane onto the exterior wall of the basement. The drive motor controls the conveyor roller to automatically feed the waterproof membrane to the pressing roller. The lead screw motor controls the lead screw to rotate, and the lead screw controls the adjustment part to move along the adjustment groove, so that the pressing roller presses the waterproof membrane onto the basement exterior wall, realizing the automatic and orderly adhesion of the waterproof membrane.

[0024] Furthermore, the clamping component includes a clamping frame, a push cylinder, a clamping part, a lifting part, and a clamping strip. The clamping frame is fixedly connected to the bottom of the adjusting seat. The push cylinder is fixedly connected to the clamping frame and has a push guide rod. A connecting plate is fixedly connected to the end of the push guide rod. One end of the clamping part is fixedly connected to the connecting plate, and the other end of the clamping part presses the rolled waterproof layer onto the exterior wall of the basement. The connecting plate has a lifting groove. A lifting connecting rod is fixedly connected to one end of the lifting part and passes through the lifting groove. A lifting cylinder is fixedly connected to the side of the connecting plate away from the lifting part. The lifting cylinder has a lifting guide rod, and the end of the lifting guide rod is fixedly connected to the lifting connecting rod. Both ends of the clamping strip have slots corresponding to the lifting part. The two ends of the lifting part are inserted into the slots, so that the clamping strip is fixedly connected to both ends of the lifting part. The clamping frame is fixed to the bottom of the adjusting seat, allowing it to rise and fall with the adjusting seat. The clamping part is controlled by a push cylinder, pressing the roll waterproofing layer firmly onto the basement exterior wall, thus increasing the adhesion strength of the roll waterproofing layer. At the same time, slots are provided at both ends of the clamping strip, through which the clamping strip is fixed to both ends of the lifting part. The lifting cylinder controls the lifting part to drive the clamping strip to rise and fall, so that the clamping strip presses one end of the roll waterproofing layer firmly onto the permanent protective wall, thereby pre-reserving the flange on the top surface of the permanent protective wall, which facilitates subsequent construction.

[0025] Furthermore, in step d, matching tenon and mortise joints are provided at both ends of the lightweight aggregate waterproof protective wall panel, so that the connecting ends of two adjacent basement exterior walls are tenon-mortised. The tenon-mortise and mortise connection between two adjacent lightweight aggregate waterproof protective wall panels facilitates their installation and fixation.

[0026] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0027] The present invention welds a first arc plate between the front panel and the side panel, and a second arc plate between the side panel and the rear panel, so that there is an arc surface between the panels, which protects the operator.

[0028] This invention involves welding a connecting plate to the inner side of the side panel, with a first inner plate welded to the connecting plate. The first inner plate is welded and fixed to the front panel, reinforcing and protecting the side panel by increasing its overall thickness and preventing deformation. Similarly, this invention involves welding a connecting frame to the inner side of the rear panel, with a second inner plate welded to the connecting frame. The side of the second inner plate is welded and fixed to the side of the first inner plate, reinforcing and protecting the rear panel by increasing its overall thickness and preventing deformation.
