Description

Technical Field

[0001] This invention patent relates to the technical field of expansion joints, and more specifically, to a caulking construction method for expansion joints in the ultra-long concrete pool walls of water treatment plants. Background Art

[0002] Expansion joints are common structures in construction engineering, used to solve the problems of structural deformation caused by factors such as temperature changes, uneven settlement of the foundation, or earthquakes in buildings.

[0003] In the construction of ultra-long concrete pool walls in water treatment plants, the construction of expansion joints is particularly important because they need to withstand the long-term effects of water pressure and temperature changes. Therefore, in traditional expansion joint construction methods, it mainly includes steps such as the setting of waterstops, the filling of caulking materials, and sealing treatment.

[0004] In the existing technology, the connection between the caulking material and the base surface mainly relies on the adhesive properties of the caulking material itself, lacking a special adhesive. This results in the caulking material being prone to separation from the base surface due to external factors (such as water pressure and temperature changes) during long-term use; although some caulking materials can meet the usage requirements of expansion joints to a certain extent, there are still deficiencies in the bonding strength with the concrete base surface. For example, asphalt-based caulking materials, although inexpensive, have poor adhesion to the concrete base surface and are prone to peeling.

[0005] In addition, during the construction process, the lack of a systematic setting of the interface layer and the bonding layer will also lead to unstable bonding strength between the caulking material and the base surface. Summary of the Invention

[0006] The purpose of this invention is to provide a caulking construction method for expansion joints in ultra-long concrete pool walls of water treatment plants, aiming to solve the problem of relatively low bonding strength between the caulking material and the concrete base surface in the existing technology.

[0007] This invention is implemented as follows. The caulking construction method for expansion joints in ultra-long concrete pool walls of water treatment plants includes the following construction steps:

[0008] 1), The expansion joint is formed between two spaced concrete pool walls, and the concrete pool walls have a base surface facing the expansion joint; a fixedly arranged waterstop is provided in the middle of the expansion joint, and the waterstop divides the expansion joint into two filling areas, and each filling area has a filling opening facing away from the waterstop; a caulking board is filled in each filling area, and there are filling gaps between both sides of the caulking board and the base surface respectively; clean the base surface to make the base surface reach the set cleanliness.

[0009] 2), Apply an interface agent on the base surface to form an interface layer, and the interface layer is located in the filling gap.

[0010] 3), Inject a filling binder into the filler gap to form a bonding layer, and the bonding layer is integrally connected to the interface layer and the caulking plate respectively;

[0011] 4), Arrange water stop bars in one of the filler areas, and both ends of the water stop bars are respectively abutted against the bonding layer;

[0012] 5), Inject sealant into the two filler areas to form a sealing layer, and the sealing layer closes the filler opening, and the sealing layer has a sealing part that closes the filler opening.

[0013] Further, in the construction step 1), during the process of cleaning the base surface, use a putty knife to remove the adhesions on the base surface.

[0014] Further, in the construction step 1), after removing the adhesions on the base surface, use a steel brush to brush and polish the base surface to remove the surface of the base surface.

[0015] Further, in the construction step 1), when using a steel brush to brush and polish the base surface, use a hair dryer to blow out the sundries in the filler gap from the filler gap.

[0016] Further, in the construction step 1), when the sundries in the filler gap are blown out, use a gas blowtorch to bake the base surface.

[0017] Further, in the construction step 2), the interface agent is Wanjie EC-1 interface agent. After the interface layer is formed on the base surface, let it stand for a set time until the surface of the interface layer stops flowing, and then apply a mixed binder on the interface layer. The mixed binder is mixed with the interface layer to form an integral body;

[0018] In the construction step 3), after the bonding layer is connected to the interface layer, the filling binder is mixed and connected to the mixed binder to form an integral body.

[0019] Further, in the construction step 2), after applying the mixed binder on the interface layer, use a scraper to reciprocally scrape the mixed binder so that the mixed binder is mixed with the interface layer to form an integral body.

[0020] Further, both the mixed binder and the filling binder are two-component epoxy adhesives.

[0021] Further, in the construction step 4), two water stop bars arranged side by side in the filler area, along the direction from the water stop belt to the filler opening, the two water stop bars are abutted in sequence and arranged side by side to form a longitudinal linear abutting position. The outside of the abutting position has an outer area, and the outer area is located between the two water stop bars and is filled with the bonding layer;

[0022] When the two water stop rods are placed in the packing area and abut against the bonding layer, rotate the two water stop rods synchronously. The two water stop rods rotate in opposite directions while abutting against the bonding layer to disturb the bonding layer until the outer circumferences of the two water stop rods are both adhered with the adhesive.

[0023] During the process of synchronously rotating the two water stop rods, use a glue spraying pipe to insert into the outer area to supplement and inject the adhesive. During the injection of the adhesive by the glue spraying pipe, the glue spraying pipe moves from the bottom to the top of the outer area until the water stop rods stop rotating and the glue spraying pipe disengages from the outer area.

[0024] Furthermore, in the construction step 5), use an iron float to compact the sealing part at the packing opening so that the sealing part is recessed inward in an arc shape.

[0025] Compared with the prior art, the construction method for caulking the deformation joint of the ultra-long concrete pool wall of the waterworks provided by the invention has the following construction technical advantages:

[0026] 1), By cleaning the base surface, ensuring that the base surface reaches the set cleanliness, providing a good foundation for subsequent construction, thereby effectively improving the bonding quality between the caulking material and the base surface; then, applying an interface agent on the base surface to form an interface layer, and the interface layer is located in the packing gap, significantly enhancing the bonding performance between the caulking material and the concrete base surface, thereby realizing the high-strength bonding between the caulking material and the base surface;

[0027] 2), Inject a filling adhesive into the packing gap to form a bonding layer, and the bonding layer is connected to the interface layer and the caulking board as a whole, further enhancing the bonding strength between the caulking material and the concrete base surface and ensuring the stability of the caulking material during long-term use;

[0028] 3), The arrangement of the water stop rods and the setting of the sealing layer not only improve the water stop performance of the deformation joint, but also provide additional support and protection for the caulking material, further enhancing the overall performance and service life of the deformation joint.

[0037] Refer to Figures 1-4 As shown, it is a preferred embodiment provided by the present invention.

[0038] The caulking construction method for the deformation joint of the ultra-long concrete pool wall of the waterworks includes the following construction steps:

[0039] 1). The deformation joint 200 is formed between two spaced concrete pool walls 100, and the concrete pool wall 100 has a base surface 101 facing the deformation joint 200; a fixedly arranged water stop belt 201 is provided in the middle of the deformation joint 200, and the water stop belt 201 divides the deformation joint 200 into two filling areas 202. The filling area 202 has a filling opening 203 facing away from the water stop belt 201; a caulking plate 204 is filled in the filling area 202, and there are filling gaps between the two sides of the caulking plate 204 and the base surface 101 respectively; the base surface 101 is cleaned to make the base surface 101 reach the set cleanliness;

[0040] 2). An interface agent is applied on the base surface 101 to form an interface layer 102, and the interface layer 102 is located in the filling gap;

[0041] 3) Inject a filling binder into the packing gap to form a bonding layer 103, and the bonding layer 103 is integrally connected to the interface layer 102 and the caulking plate 204 respectively;

[0042] 4) Arrange a water stop rod 104 in a packing area 202, and both ends of the water stop rod 104 are respectively abutted against the bonding layer 103;

[0043] 5) Inject sealant into the two packing areas 202 to form a sealing layer 205. The sealing layer 205 closes the packing opening 203, and the sealing layer 205 has a sealing portion 206 that closes the packing opening 203.

[0044] The provided caulking construction method for the deformation joint of the ultra-long concrete pool wall of the waterworks has the following construction technical advantages:

[0045] 1) By cleaning the base surface 101, ensuring that the base surface 101 reaches the set cleanliness, it provides a good foundation for subsequent construction, thereby effectively improving the bonding quality between the caulking material and the base surface 101; then, an interface agent is applied on the base surface 101 to form an interface layer 102. The interface layer 102 is located in the packing gap, significantly enhancing the bonding performance between the caulking material and the concrete base surface 101, thereby achieving a high-strength bond between the caulking material and the base surface 101;

[0046] 2) Inject a filling binder into the packing gap to form a bonding layer 103. The bonding layer 103 is integrally connected to the interface layer 102 and the caulking plate 204 respectively, further enhancing the bonding strength between the caulking material and the concrete base surface 101 and ensuring the stability of the caulking material during long-term use;

[0047] 3) The arrangement of the water stop rod 104 and the setting of the sealing layer 205 not only improve the water stop performance of the deformation joint 200, but also provide additional support and protection for the caulking material, further enhancing the overall performance and service life of the deformation joint 200.

[0048] In this embodiment, in construction step 1), during the process of cleaning the base surface 101, use a putty knife to remove the adhesions on the base surface 101.

[0049] In this way, it can effectively remove the sundries and floating ash on the base surface 101, provide a clean foundation for subsequent construction, thereby improving the bonding quality between the caulking material and the base surface 101, and laying a foundation for achieving a high-strength bond between the caulking material and the concrete base surface 101.

[0050] In this embodiment, in construction step 1), after removing the adhesions on the base surface 101, use a steel brush to brush and polish the base surface 101 to remove the surface of the base surface 101.

[0051] Through the grinding of the steel brush, the uneven parts of the base surface 101 are further cleaned, and the roughness of the base surface 101 is enhanced, providing better physical conditions for the adhesion of the interface agent and the binder, effectively improving the bonding strength between the base surface 101 and the caulking material.

[0052] In this embodiment, in construction step 1), after the base surface 101 is brushed and ground with a steel brush, a blower is used to blow out the debris in the filler gap from the filler gap.

[0053] In this way, the residual debris in the filler gap can be thoroughly cleaned, ensuring the cleanliness of the filler gap, providing a good space for the subsequent injection of the binder, and further improving the bonding effect between the caulking material and the base surface 101.

[0054] In this embodiment, in construction step 1), after the debris in the filler gap is blown out, a gas torch is used to bake the base surface 101.

[0055] In this way, the moisture on the base surface 101 can be removed during the baking process, preventing the influence of moisture on the performance of the binder during subsequent construction. At the same time, the dryness and cleanliness of the base surface 101 are further improved, providing a guarantee for the tight bonding between the caulking material and the base surface 101.

[0056] In this embodiment, in construction step 2), the interface agent is Wanjie EC-1 interface agent. After the interface layer 102 is formed on the base surface 101, it is left standing for a set time until the surface of the interface layer 102 stops flowing, and then the mixed binder is applied on the interface layer 102, and the mixed binder is mixed with the interface layer 102 to form an integral body;

[0057] In construction step 3), after the bonding layer 103 is connected to the interface layer 102, the filling binder and the mixed binder are mixed and connected into an integral body.

[0058] Through the synergistic effect of the interface agent and the binder, the bonding performance between the caulking material and the concrete base surface 101 is significantly enhanced, effectively solving the problem of the low bonding strength between the caulking material and the base surface 101.

[0059] In this embodiment, in construction step 2), after the mixed binder is applied on the interface layer 102, a squeegee is used to reciprocally scrape the mixed binder so that the mixed binder is mixed with the interface layer 102 to form an integral body.

[0060] Through the scraping operation of the squeegee, the mixed binder can be evenly distributed and tightly combined with the interface layer 102, further improving the strength and stability of the bonding layer 103, and ensuring the firm bonding between the caulking material and the base surface 101.

[0061] In this embodiment, both the mixed binder and the filling binder are two-component epoxy adhesives.

[0062] Utilizing the characteristics of the two-component epoxy adhesive, such as high strength, durability, and good bonding performance, it can effectively enhance the bonding strength between the caulking material and the base surface 101, while improving the durability and stability after construction.

[0063] In this embodiment, in construction step 4), two water stop bars 104 arranged side by side in the filler area 202 are sequentially abutted along the direction from the water stop belt 201 to the filler opening 203, forming a longitudinal linear abutting position. There is an outer area 105 outside the abutting position. The outer area 105 is located between the two water stop bars 104 and is filled with the bonding layer 103.

[0064] When the two water stop bars 104 are placed in the filler area 202 and abut against the bonding layer 103, the two water stop bars 104 rotate in opposite directions while abutting against the bonding layer 103, disturbing the bonding layer 103 until the outer circumferences of the two water stop bars 104 are both adhered with the adhesive.

[0065] During the process of synchronously rotating the two water stop bars 104, the bonding agent is supplemented and injected by inserting the glue spraying pipe into the outer area 105. During the injection of the bonding agent by the glue spraying pipe, it moves from the bottom to the top of the outer area 105 until the water stop bars 104 stop rotating and the glue spraying pipe disengages from the outer area 105.

[0066] Through the abutment and opposite rotation of the water stop bars 104, the bonding layer 103 can be effectively disturbed, enabling the adhesive to fully fill the gap between the water stop bars 104 and the bonding layer 103, ensuring the tight combination of the water stop bars 104 and the bonding layer 103. At the same time, by supplementing and injecting the bonding agent from the bottom to the top of the outer area 105 through the glue spraying pipe, the voids in the outer area 105 are further filled, avoiding the problem of insecure bonding caused by insufficient bonding agent. This not only enhances the bonding strength between the water stop bars 104 and the bonding layer 103 but also improves the water stop performance, ensuring the stability and waterproof effect of the deformation joint 200 during long-term use.

[0067] In this embodiment, in construction step 5), a trowel is used to compact the sealing part 206 at the filler opening 203 so that the sealing part 206 is recessed inward in an arc shape.

[0068] In this way, the compactness and uniformity of the sealing layer 205 can be ensured, the waterproof performance of the sealing part 206 can be improved, and the overall performance and service life of the deformation joint 200 can be further enhanced.

[0069] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
