[0002] In some concrete wall construction, in order to reduce the damage to the wall structure caused by the thermal expansion and contraction effect caused by thermal stress, such as surface cracks and internal cracks, induced joints are usually set on the outer surface of the wall (such as the exterior facade of the building and the interior facade of the indoor wall) to release the internal stress of this part of the thermal expansion and contraction effect through the induced joints. Some reinforcement materials made of expansive concrete are even filled in the induced joints to strengthen the wall strength at the induced joints. However, in the construction process of some super-long concrete walls, due to the long construction period, the opening position of the induced joints is difficult to reflect the stress release position of the super-long concrete wall, resulting in surface cracks, internal cracks and other damages on the wall structure between the induced joints, which makes the construction of super-long concrete walls difficult and the wall quality poor.

The beneficial effects of the present invention are: In the enhanced foamed concrete wall of the present invention, the foaming layer is used as a buffer layer between the impermeable layer and the expansion layer.

Compared with the existing induced joints that need to be set at the stress release position of the wall, the enhanced foamed concrete wall of the present invention directly releases stress with the foaming layer in the interlayer, and uses the method of replacing foamed concrete and sulfur mortar to ensure the compactness of the enhanced foamed concrete wall, thereby achieving the effect of improving the construction quality of the concrete wall.

[0020] Figure 1 FIG. 2 shows a schematic structural diagram of a reinforced foamed concrete wall according to an embodiment of the present invention. Figure 1 As shown, combined with Figure 2 and Figure 3 In the embodiment of the present invention, the enhanced foamed concrete wall has an anti-seepage layer 100, a foamed layer 200 and an expansion layer 300 arranged in sequence from back to front, a transverse steel bar 210 extending forward and backward is embedded in the foamed layer 200, the front end of the transverse steel bar 210 extends into the expansion layer 300, and / or the rear end of the transverse steel bar 210 extends into the anti-seepage layer 100, and a discharge port 320 is arranged on one of the top and bottom of the expansion layer 300, and a material injection port 330 is arranged on the other, and both the material injection port 330 and the discharge port 320 penetrate the expansion layer 300 in the front-to-back direction; and an anti-seepage layer 100 is cast in place between the base soil 400 and the temporary wall 500. Permeable concrete is used to form an impermeable layer 100; wherein the temporary wall 500 is prefabricated with sulfur mortar, and the transverse steel bars 210 are pre-buried in the temporary wall 500, and both ends of the steel bars extend from the front and rear sides of the temporary wall 500; expansive concrete is cast between the vertical formwork (not shown in the figure) and the temporary wall 500 to form an expansive layer 300; wherein the vertical formwork is arranged in front of the temporary wall 500; after the expansion layer 300 and the impermeable layer 100 are formed, the temporary wall 500 is removed by an electric thermal melting method, and foamed concrete is cast from the injection port 330 until the sulfur mortar is discharged from the discharge port 320 to form a foaming layer 200.
[0021] Specifically, the construction process of the enhanced foamed concrete wall of the present invention includes at least the following steps: S100, preparing a temporary wall 500.
[0022] Sulphur mortar is poured into the mold of the pre-embedded transverse reinforcement 210, and after being formed and solidified, a temporary wall 500 is obtained. Both ends of the transverse reinforcement 210 extend from the front and rear sides of the temporary wall 500, and the extended parts are equal in length, so there is no need to prevent fooling during the construction process.
[0023] S200, erecting a temporary wall 500 and a formwork.
[0024] The temporary wall 500 and the vertical formwork are sequentially erected in front of the base soil 400 from the back to the front, and a first spacing is reserved between the temporary wall 500 and the base soil 400, and a second spacing is reserved between the vertical formwork and the temporary wall 500. The thickness of the first spacing is greater than the thickness of the impermeable layer 100, and the thickness of the second spacing is less than the thickness of the expansion layer 300. At the same time, the transverse steel bars 210 are horizontally distributed in the front-to-back direction, and the two ends of the transverse steel bars 210 extend into the first spacing and the second spacing respectively.
[0025] S300, cast-in-place anti-seepage layer 100.
[0026] In the first gap between the temporary wall 500 and the foundation soil layer, impermeable concrete is poured from top to bottom.
[0027] S400, cast-in-place expansion layer 300.
[0028] Before the impermeable concrete is completely formed and solidified, or while pouring the impermeable concrete, the expansive concrete is poured from top to bottom into the second gap between the vertical formwork and the temporary wall 500. In addition, an upper pouring channel and a lower pouring channel connected to the temporary wall 500 are reserved on the vertical formwork so that the injection port 330 and the discharge port 320 are formed simultaneously during the process of forming the expansive concrete.
[0029] S500, removing the temporary wall 500 and the cast-in-place foaming layer 200.
[0030] When the impermeable layer 100 is completely formed and solidified, and the expansion layer 300 is solidified for a period of time (no more than 24 hours), the temporary wall 500 is energized by electric heating melting method to release the solidified state of the sulfur mortar in the temporary wall 500; at the same time, the foamed concrete is injected into the interlayer space between the expansion layer 300 and the impermeable layer 100 from the injection port 330, and it is necessary to ensure that the discharge amount of the sulfur mortar from the discharge port 320 and the injection amount of the foamed concrete from the main material port are basically the same or completely the same, or the injection amount is slightly larger, so as to realize the pressurized injection of the foamed concrete. In particular, when the main material port is located at the bottom of the expansion layer 300, a greater pouring pressure is required when injecting the foamed concrete, which also makes the foamed layer 200 more compact after forming.
[0031] S600, molding and curing.
[0032] After the foamed concrete overflows from the discharge port 320, the pouring of the foamed concrete is stopped, and the injection port 330 and the discharge port 320 on the vertical formwork are closed to form and solidify the enhanced foamed concrete wall.
[0033] In the enhanced foamed concrete wall of the present invention, the foaming layer 200 is used as a buffer layer between the anti-seepage layer 100 and the expansion layer 300, which ensures the compactness of the enhanced foamed concrete wall and achieves the effect of improving the construction quality of the concrete wall.
[0034] Figure 3 FIG. 2 shows a schematic diagram of the pouring process of the foaming layer 200 in the enhanced foamed concrete wall according to an embodiment of the present invention. Figure 3 As shown, combined with Figure 1It can be known that in some preferred embodiments of the present invention, the first embedded steel bar 110 is embedded in the impermeable layer 100, the first embedded steel bar 110 is vertically arranged, and the first embedded steel bar 110 is tied and connected to the rear end of the transverse steel bar 210, so as to promote the first embedded steel bar 110 to be solidified in the impermeable layer 100 during the impermeable concrete forming process; and / or, the second embedded steel bar 310 is embedded in the expansion layer 300, the second embedded steel bar 310 is vertically arranged, and the second embedded steel bar 310 is tied and connected to the front end of the transverse steel bar 210, so as to promote the second embedded steel bar 310 to be solidified in the expansion layer 300 during the expansion concrete forming process.
[0035] In the enhanced foamed concrete wall of the present invention, the bonding force between the layers of the enhanced foamed concrete wall is made tighter by pre-embedding the first embedded steel bars 110 / second embedded steel bars 310 extending vertically in the anti-seepage layer 100 and / or the expansion layer 300. In particular, during the forming process of the expansion layer 300, the expansion pressure can be directly transmitted to the second embedded steel bars 310 through the transverse steel bars 210 to compact the anti-seepage layer 100, so that the anti-seepage effect of the anti-seepage layer 100 is better.
[0036] In some preferred embodiments of the present invention, Figure 2 As shown, a plurality of adhesive capsules 220 spaced apart in the up-down direction are embedded in the foam layer 200 . The adhesive capsules 220 include a shell made of glass or plastic material, and the shell is filled with a slow-setting adhesive liquid to facilitate the slow-setting adhesive liquid to enter the foam layer 200 after the shell is broken.
[0037] In the enhanced foamed concrete wall of the present invention, when the temperature difference of the base soil 400 changes greatly, especially when the temperature is too low, the anti-seepage layer 100 is prone to cracks due to the frozen ice in the base soil 400. At this time, due to the increased brittleness of the concrete in each layer and the erosion by the frozen ice water in the base soil 400, the viscose capsules 220 in the foaming layer 200 are broken to release the slow-setting adhesive liquid to fill the cracks and gaps in the foaming layer 200 to achieve a self-healing effect.
[0038] In some preferred embodiments of the present invention, Figure 2 As shown, the viscose capsule 220 is externally clamped with a positioning frame 230 made of metal or plastic, and the top of the positioning frame 230 is connected to the transverse steel bars 210; and, in the up and down directions, the transverse steel bars 210 are distributed in layers, and the transverse steel bars 210 of each layer are spaced apart in the left and right directions, and the distance between two adjacent transverse steel bars 210 of each layer is less than the minimum outer diameter of the viscose capsule 220.
[0039] In the reinforced foamed concrete wall of the present invention, the positioning frame 230 is used to connect the viscose capsule 220 and the transverse steel bar 210 together, so that after the curing state of the sulfur mortar in the temporary wall 500 is released, the viscose capsule 220 can still be retained in the original position, that is, retained in the same position as in the temporary wall 500. Therefore, it is convenient for the construction party to set the viscose capsule 220 at the preset position, and the placement position is reliable and reasonable. In particular, it is avoided that the viscose capsule 220 is concentrated on the top or bottom of the foaming layer 200 under the impact of the foamed concrete. That is, the viscose capsule 220 is kept dispersed.
[0040] Furthermore, by using a smaller spacing between each layer of transverse reinforcement bars 210, after the adhesive capsule 220 accidentally falls off the positioning frame 230, it will still be spaced in a smaller range, thereby maintaining the adhesive capsule 220 in the preset position to the greatest extent.
[0041] In some preferred embodiments of the present invention, the viscose capsule 220 has a cylindrical abdomen, and a hemispherical upper head and a lower head are integrally formed at both ends of the abdomen to cause the axis of the viscose capsule 220 to be in a vertical direction; and, in the case where the positioning frame 230 is made of metal material, the positioning frame 230 includes an abdomen clamping ring 231 that is sleeved and embedded in the abdomen of the viscose capsule 220, and a U-shaped hanging ring 232 is welded to the outside of the abdomen clamping ring 231, and the hanging ring 232 is sleeved and embedded in the upper side of the upper half of the viscose capsule 220; and, a hook 233 that is hooked and connected to the transverse steel bar 210 is welded on the hanging ring 232, and an umbrella cover 234 that covers the top of the viscose capsule 220 is also welded on the hook 233; and, the projection of the viscose capsule 220 on the horizontal plane completely falls into the umbrella cover 234. It can be seen that the use of the umbrella cover 234 to cover the viscose capsule 220 can prevent the viscose capsule 220 from being washed off during the process of pouring the foamed concrete from top to bottom, and further ensures that the viscose capsule 220 is in the preset position.
[0042] In some preferred embodiments of the present invention, a first grid 240 made of metal material is sandwiched between the foaming layer 200 and the impermeable layer 100, and the first grid 240 is configured to be movably sleeved on the rear section of the transverse reinforcement 210 before pouring the impermeable concrete; and / or, a second grid 250 made of metal material is sandwiched between the foaming layer 200 and the expansion layer 300, and the second grid 250 is configured to be movably sleeved on the front section of the transverse reinforcement 210 before pouring the expansion concrete. It can be seen that the use of the first grid 240 and the second grid 250 can not only be used as an electric heating carrier to electrically heat the sulfur mortar during the process of removing the temporary wall 500, but also can be used to shape the interlayer concrete and strengthen the interlayer.
[0043] In some preferred embodiments of the present invention, when the discharge port 320 is located at the bottom of the expansion layer 300 and the injection port 330 is located at the top of the expansion layer 300, the discharge port 320 and / or the injection port 330 are in the shape of a channel whose bottom gradually slopes downward from the back to the front. It can be seen that the use of a downwardly inclined channel can facilitate the discharge of sulfur mortar and the injection of foamed concrete; especially in the case of pouring foamed concrete from the bottom to the top, it is also convenient for the foamed concrete to overflow from the top of the expansion layer 300.
[0044] In some preferred embodiments of the present invention, the discharge port 320 and / or the injection port 330 are filled with foaming material. It can be seen that after the pouring of the foamed concrete is completed, the discharge port 320 can be closed so that the foamed concrete fills the discharge port 320 and the injection port 330, so that after the enhanced foamed concrete wall is formed and solidified, the injection port 330 and the discharge port 320 are also blocked by the foamed concrete. In this way, on the one hand, the integrity of the enhanced foamed concrete wall is enhanced, and on the other hand, the foamed concrete reserved in the expansion layer 300 can also improve the toughness of the expansion layer 300 itself, so that the deformation of the expansion layer 300 itself can also be buffered by the foamed concrete.
[0045] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
