Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of building reconstruction, and in particular to a method for reinforcing a side wall of a garbage pool. Background Art
[0002] In the field of industrial construction, in order to expand the storage scale and increase the storage capacity, large garbage pools are usually built with reinforced concrete materials to store garbage or industrial materials. The materials piled in the pool act on the side walls of the garbage pool, mainly generating horizontal loads.
[0003] On the one hand, with the gradual expansion of production scale, the daily stacking volume of materials in the garbage pool has gradually increased, increasing the load on the side walls. On the other hand, the bearing capacity of the side walls of the garbage pool has been continuously decreasing with the increase of years of use, and damage and cracks on the side walls of the garbage pool often occur.
[0004] At the same time, in order to facilitate personnel to inspect the storage conditions of materials in the pool, such as Figure 1 As shown, the outer surface of the side wall of the garbage pool is connected with walking platform plates at different heights and support columns for supporting the platform plates. The platform plates and the support columns cross each other to divide the outer surface of the side wall into multiple independent areas, which increases the structural complexity of the outer surface of the side wall and further increases the difficulty of reinforcing the side wall. Summary of the invention
[0005] A technical problem to be solved by the present disclosure is: how to effectively reinforce the side walls of an existing garbage pool to improve its bearing capacity.
[0006] In order to solve the above technical problems, the embodiment of the present disclosure provides a method for reinforcing the side wall of a garbage pool. The outer wall surface of the side wall of the existing garbage pool is connected with multiple layers of platform plates extending in the horizontal direction, and the outer wall surface of the side wall is also connected with multiple support columns extending in the vertical direction for supporting the platform plates. The multiple platform plates and the multiple support columns are cross-distributed on the outer wall surface of the side wall. The construction method includes: S1. Roughening the concrete of the outer wall surface of the side wall; S2. Dividing the area surrounded by two adjacent platform plates and two support columns into a reinforcement unit, laying reinforcement layer steel bars in the reinforcement unit, and anchoring the ends of the reinforcement layer steel bars into the platform plates or support columns that enclose the reinforcement unit; S3. Supporting formwork and casting the reinforcement layer.
[0007] In some embodiments, in S1, the original steel bars of the side wall are exposed during the roughening process; in S2, the steel bars of the reinforcement layer are connected to the original steel bars to strengthen the connection between the reinforcement layer and the side wall.
[0008] In some embodiments, in S2, the reinforcement layer steel bars include plate bars and beam bars; wherein the plate bars are bidirectionally laid, the beam bars are horizontally laid, and both ends of the beam bars are anchored into two support columns respectively.
[0009] In some embodiments, the plate reinforcement is laid in double layers, and tie bars are also provided on the plate reinforcement, and the tie bars are welded and connected to the original steel bars.
[0010] In some embodiments, the tie bars are arranged in a plum blossom arrangement.
[0011] In some embodiments, stirrups are provided on the beam reinforcement, and the stirrups are welded to the original steel bars.
[0012] In some embodiments, in S2, before laying the reinforcement layer steel bars, corresponding anchor holes are drilled on the platform plate and the support columns.
[0013] In some embodiments, the anchoring holes of adjacent reinforcement units are staggered.
[0014] In some embodiments, in S3, when pouring the reinforcement layer, a grouting material with a higher strength grade than the side wall is used.
[0015] In some embodiments, in S2, when full-layer anchoring is performed between two adjacent platform plates, multiple groups of beam reinforcements are distributed along the height direction between the two platform plates located on both sides of the reinforcement unit, and the top of the plate reinforcement along the height direction is anchored into the platform plate located above the reinforcement unit; or in S2, when non-full-layer anchoring is performed between two adjacent platform plates, multiple groups of beam reinforcements are distributed along the height direction between the platform plate located below the reinforcement unit and the designed reinforcement height, and the top of the plate reinforcement along the height direction is connected to the beam reinforcement located at the top.
[0016] Through the above technical scheme, the garbage pool side wall reinforcement construction method provided by the present invention divides the side wall into independent reinforcement units through the platform plate and support columns on the outer wall surface of the original structure side wall for easy reinforcement. At the same time, the steel bars are anchored into the platform plate and the support columns, making full use of the existing structure on the outer wall surface of the garbage pool side wall, effectively strengthening the ability of the garbage pool side wall to resist horizontal loads and enhancing the stability of the structure.

[0027] like Figure 1 and Figure 2As shown, the present disclosure provides a method for reinforcing the side wall of a garbage pool. The outer wall surface of the side wall 1 of the existing garbage pool is connected with multiple layers of platform plates 2 extending in the horizontal direction. The outer wall surface of the side wall 1 is also connected with multiple support columns 3 extending in the vertical direction for supporting the platform plates 2. The multiple platform plates 2 and the multiple support columns 3 are cross-distributed on the outer wall surface of the side wall 1. The construction method includes: S1, roughening the outer wall surface concrete of the side wall 1; S2, dividing the area surrounded by two adjacent platform plates 2 and two support columns 3 into a reinforcement unit 4, laying reinforcement layer steel bars 501 in the reinforcement unit 4, and anchoring the ends of the reinforcement layer steel bars 501 into the platform plates 2 or support columns 3 that enclose the reinforcement unit 4; S3, supporting formwork and casting the reinforcement layer 5.
[0028] Specifically, in order to facilitate the staff to observe the accumulation situation in the garbage pool, a multi-layer platform plate 2 is connected to the outer wall surface of the side wall 1 of the existing garbage pool for people to walk on, and a plurality of support columns 3 extending in the vertical direction are also arranged side by side on the outer wall surface of the side wall 1. The multi-layer platform plate 2 and the plurality of support columns 3 cross each other on the outer wall surface, and the outer wall surface of the side wall 1 is divided into a plurality of rectangular reinforcement units 4. The reinforcement layer steel bars 501 of the side wall 1 are cross-laid in the vertical and horizontal directions in the reinforcement unit 4, and the grouting material is poured to form a reinforcement layer 5. After pouring, the reinforcement layer 5 is parallel to the side wall 1, and is bonded to the side wall 1 through the roughened surface of the side wall 1, thereby increasing the thickness of the side wall 1 to improve the horizontal load resistance of the side wall 1.
[0029] Before reinforcing the side wall 1, first determine the reinforcement height. If there is local damage on the side wall 1 at a position exceeding the reinforcement height, the reinforcement unit 4 where the damage is located should be locally reinforced. During the reinforcement construction, in S1, roughening the side wall 1 can increase the bonding force between the reinforcement layer 5 and the side wall 1. The roughening of the side wall 1 can be done by hammering, wheel grinding machine or high-pressure water jet roughening, etc., and the selection should be made according to the actual situation. After the roughening is completed, the surface of the side wall 1 is cleaned, the side wall 1 is inspected, and the cracks that have appeared are repaired. Repair glue can be used to seal the cracks; in S2, the reinforcement layer steel bars 501 are arranged in the reinforcement unit 4. In order to increase the bearing capacity of the reinforcement layer 5 and facilitate construction, the reinforcement layer steel bars 501 are cross-arranged in the horizontal and vertical directions. The two ends of the reinforcement layer steel bars 501 arranged in the horizontal direction are anchored into the two sides of the reinforcement unit 4 respectively. In the root support column 3, the lower end of the reinforcement layer steel bar 501 arranged in the vertical direction is anchored in the platform plate 2 below the reinforcement unit 4, and the upper end is determined according to the reinforcement height. When the reinforcement unit 4 needs to be fully reinforced, its upper end is anchored in the platform plate 2 located above. When the reinforcement unit 4 only needs to be partially anchored in the height direction, its upper end is connected to the beam bar 503 of the uppermost horizontal beam 506 to connect to the existing structure; in S3, when the reinforcement layer steel bar 501 is poured, the formwork is supported. A single-sided oblique support located on the outside of the side wall 1 can be used, or a tension screw can be set on the side wall 1. After the construction is completed, the screw eye is repaired. After the pouring is completed, the reinforcement layer 5 is cured to the design strength before the formwork is removed.
[0030] After the construction is completed, the newly added reinforcement layer 5 and the side wall 1 together form the pool wall of the garbage pool, increasing the thickness of the pool wall. The reinforcement layer steel bars 501 serve as the outer steel bars of the pool wall, and the original steel bars 101 serve as the inner steel bars of the pool wall, jointly bearing the load, effectively improving the ability of the garbage pool wall to resist horizontal loads, and the reinforcement layer 5 is effectively combined with the platform plate 2 and support column 3 in the existing structure, further enhancing the stability of the overall structure. In some embodiments, after the outer wall surface of the side wall 1 is roughened, an interface agent may be applied on the outer wall surface as a transition layer. The interface agent can effectively increase the surface roughness, which is beneficial to improving the bonding force between the reinforcement layer 5 and the side wall 1 .
[0031] like Figure 3 and Figure 4 As shown, in some embodiments, in S1 , the original steel bars 101 of the side wall 1 are exposed during the roughening process; in S2 , the reinforcement layer steel bars 501 are connected to the original steel bars 101 to strengthen the connection between the reinforcement layer 5 and the side wall 1 .
[0032] Specifically, in order to improve the bonding strength between the reinforcement layer 5 and the side wall 1, in S1, the concrete protective layer on the outer wall surface of the side wall 1 is completely removed during roughening to expose the original steel bars 101 in the side wall 1, and the original steel bars 101 are derusted. The rust remover can be sprayed or polished with an angle grinder. In S2, when laying the reinforcement layer steel bars 501, the reinforcement layer steel bars 501 can be slightly bent to fit the original steel bars 101, and then the two are welded together. It is also possible to provide auxiliary steel bars such as tie bars 504 or stirrups 505 on the reinforcement layer steel bars 501, and achieve indirect connection through welding the auxiliary steel bars to the original steel bars 101. The connection between the reinforcement layer steel bars 501 and the original steel bars 101 further strengthens the bonding strength between the reinforcement layer 5 and the side wall 1, which is beneficial for the reinforced pool wall as a whole to bear horizontal loads.
[0033] like Figures 2 to 7 As shown, in S2, the reinforcement layer steel bars 501 include plate bars 502 and beam bars 503; wherein the plate bars 502 are laid bidirectionally, and the beam bars 503 are laid horizontally, and both ends of the beam bars 503 are anchored into two support columns 3 respectively.
[0034] Specifically, by dividing the reinforcement layer steel bars 501 into plate bars 502 and beam bars 503, the poured reinforcement layer 5 is divided into reinforcement plates 507 and horizontal beams 506 according to the types of steel bars. The diameter of the beam bars 503 is larger than the diameter of the plate bars 502. The plate bars 502 can be made of threaded steel bars with a spacing of 200 mm and a diameter of 12 mm, which are cross-laid across the entire reinforcement unit 4 in the horizontal and vertical directions. The plate bars 502 are mainly used to transfer the load received by the reinforcement plate 507 to the horizontal beams 506 or the existing structure. The purpose of covering the plate bars 502 is to prevent shrinkage cracks from appearing on the outer surface of the reinforcement layer 5. The beam bars 503 are laid according to the number of horizontal beams 506 in the reinforcement unit 4 during design. A group of beam bars 503 is laid at one horizontal beam 506. 16 threaded steel bars with a diameter of 18 mm can be used as a group of beam bars 503. The horizontal beams 506 are mainly used to connect with the existing structure to form a frame to bear the main load. The frame can effectively increase the integrity and stability of the entire structure.
[0035] like Figure 3 As shown, in some embodiments, the plate reinforcement 502 is laid in double layers, and tie bars 504 are further provided on the plate reinforcement 502 , and the tie bars 504 are welded and connected to the original steel bars 101 .
[0036] Specifically, the double-layer reinforcement of the plate reinforcement 502 can effectively increase the thickness of the reinforcement layer 5, so that the reinforced pool wall can bear a larger horizontal load. At the same time, it can effectively increase the stiffness of the reinforcement plate 507 after pouring and reduce its deformation cracks. Tie bars 504 are arranged between the two layers of plate reinforcement 502 to strengthen the connection. Both ends of the tie bars 504 are respectively provided with 135° hooks. During operation, the hooks at both ends of the tie bars 504 are respectively hooked on the intersection of the horizontal bars and the vertical bars on the two layers of plate reinforcement 502 to obtain a better tie effect. At the same time, the end of the tie bar 504 close to the side wall 1 is welded to the original steel bar 101, so that the plate reinforcement 502 is connected to the original steel bar 101 as a whole, thereby improving the bonding force between the reinforcement layer 5 and the side wall 1, and avoiding the influence of direct welding of the plate reinforcement 502 on its force-bearing performance.
[0037] In some embodiments, the tie bars 504 are arranged in a plum blossom pattern. Specifically, tie bars 504 with a spacing of 600 mm and a diameter of 8 mm can be used on the plate bars 502. Under the same setting spacing, compared with the rectangular arrangement, the plum blossom arrangement is more dense, which increases the number of tie bars 504 and can improve the force performance of the reinforcement plate 507.
[0038] like Figure 4 As shown, in some embodiments, stirrups 505 are provided on the beam reinforcement 503 , and the stirrups 505 are welded to the original steel bars 101 .
[0039] Specifically, the stirrups 505 can be arranged with threaded steel bars with a spacing of 200 mm and a diameter of 10 mm. The provision of stirrups 505 can effectively improve the shear resistance of the horizontal beam 506. The beam reinforcement 503 is indirectly connected to the original steel bar 101 through welding between the stirrups 505 and the original steel bar 101, avoiding direct welding of the beam reinforcement 503 and affecting its bearing performance.
[0040] like Figures 5 to 7 As shown, in some embodiments, in S2 , before laying the reinforcement layer steel bars 501 , corresponding anchor holes 6 are drilled on the platform plate 2 and the support column 3 .
[0041] Specifically, before laying the reinforcement layer steel bars 501, first determine the anchoring position of the ends of the reinforcement layer steel bars 501 on the platform plate 2 and the support column 3, and open anchor holes 6 at corresponding positions. The diameter of the anchor holes 6 should be 4 to 8 mm larger than the diameter of the reinforcement layer steel bars 501, and the depth of the anchor holes 6 should not be less than 300 mm. After the anchor holes 6 are drilled, use a hair dryer to remove debris from the holes. After cleaning, inject special anchor glue into the anchor holes 6, and insert the ends of the reinforcement layer steel bars 501 into the anchor holes 6 to the designed depth. This process should ensure that the anchor glue overflows the anchor holes 6, and let it stand for a while to ensure that the anchor glue is cured.
[0042] In some embodiments, before drilling the anchor holes 6, a steel bar detector should be used to detect the position of the steel bars in the existing structure to avoid damaging the stress-bearing steel bars inside the existing structure during the drilling process.
[0043] like Figure 5 and Figure 6 As shown, in some embodiments, the anchor holes 6 of adjacent reinforcement units 4 are arranged in a staggered manner. In order to avoid the phenomenon of local stress concentration inside the existing structure caused by the anchor holes 6 on both sides of the platform plate 2 or the support column 3 being arranged in the same straight line, the anchor holes 6 of adjacent reinforcement units 4 are arranged in a staggered manner.
[0044] In some embodiments, in S3, when pouring the reinforcement layer 5, a grouting material with a higher strength grade than the side wall 1 is used. Specifically, compared with ordinary concrete, the grouting material has the advantages of good fluidity, rapid solidification and high early strength, which can effectively shorten the construction period, and based on the high fluidity of the grouting material, it can avoid the formation of gaps between the reinforcement layer 5 and the side wall 1, while reducing the vibration requirements during the pouring process and reducing the difficulty of construction.
[0045] like Figure 2 As shown, in some embodiments, in S2, when whole-layer anchoring is performed between two adjacent platform plates 2, multiple groups of beam reinforcements 503 are distributed along the height direction between the two platform plates 2 located on both sides of the reinforcement unit 4, and the top of the plate reinforcement 502 along the height direction is anchored into the platform plate 2 located above the reinforcement unit 4; or in S2, when non-whole-layer anchoring is performed between two adjacent platform plates 2, multiple groups of beam reinforcements 503 are distributed along the height direction between the platform plate 2 located below the reinforcement unit 4 and the designed reinforcement height, and the top of the plate reinforcement 502 along the height direction is connected to the beam reinforcement 503 located at the top.
[0046] Specifically, before reinforcing the side wall 1 of the garbage pool, the reinforcement height of the side wall 1 should be determined according to actual conditions. Normally, the reinforcement unit 4 at the bottom adopts full-layer reinforcement, that is, the reinforcement layer 5 is fully distributed between two adjacent platform plates 2, and the reinforcement unit 4 at the top adopts non-full-layer reinforcement, that is, the top of the reinforcement layer 5 is located between the two platform plates 4 of the reinforcement unit 4.
[0047] When full-layer reinforcement is adopted, the two ends of the plate reinforcement 502 arranged in the vertical direction are directly anchored into the two platform plates 2. When non-full-layer reinforcement is adopted, a horizontal beam 506 is set at the top of the reinforcement layer 5 to connect the upper ends of the plate reinforcement 502 arranged in the vertical direction with the beam reinforcement 503 in the horizontal beam 506.
[0048] In some embodiments, when there are multiple horizontal beams 506 between two adjacent platform plates 2, they should be cast layer by layer according to the number of horizontal beams 506. Except for the horizontal beam 506 at the bottom, one horizontal beam 506 should be cast at a time along the height direction. After curing to the designed strength, the next horizontal beam 506 can be cast by supporting the formwork. This is convenient for setting up the supporting formwork and also ensures safety during the casting process.
[0049] The following is an explanation of the construction method for reinforcing the side wall of a garbage pool in conjunction with a specific embodiment.
[0050] S1. Determine the reinforcement height of the side wall 1, remove the concrete protective layer on the outer wall surface of the side wall 1 within the reinforcement range to expose the original steel bars 101, apply rust remover to the original steel bars 101, clean the outer wall surface after roughening, check whether there are cracks on the outer wall surface, if so, use repair glue to seal the surface, apply repair glue with a width of 20-30mm and a thickness of 2-3mm along the cracks, and after cleaning and repairing, apply interface glue on the outer wall surface to increase the surface roughness for later bonding; When anchoring the entire layer: S2. Drill anchor holes 6 at the corresponding positions of the platform plate 2 and the support column 3 to prepare for laying. After the preparation is completed, first anchor some beam reinforcements 503.

After the anchoring is completed, tie bars 504 (using threaded steel bars with a spacing of 600mm and a diameter of 8mm) are set between the two layers of plate bars 502, and the tie bars 504 are welded to the original steel bars 101; S3, setting up the formwork, first using grouting material to cast the first horizontal beam 506, the second horizontal beam 506 and the reinforcement plate 507 located between the two horizontal beams 506, and after the casting is completed, curing to the design strength; Repeat S2, and the remaining beam reinforcement 503 of the third horizontal beam 506 close to the upper platform plate 2 (design section size is 600×500mm (width×height), the beam reinforcement uses 12 threaded steel bars with a diameter of 16mm, the reinforcement diagram is as shown Fig. 9 As shown) and the remaining plate reinforcement 502 (using double-layer bidirectional laying of threaded steel bars with a spacing of 200mm and a diameter of 10mm) are laid and anchored, and then welded; Repeat S3 to perform formwork pouring to complete the anchoring of the entire layer; When anchoring is not done in the entire layer: S2. Drill anchor holes 6 at the corresponding positions of the platform plate 2 and the support column 3 to prepare for laying. After the preparation is completed, first anchor the beam reinforcement 503. Set the beam reinforcement 503 of the first horizontal beam 506 near the lower platform plate 2 (the design cross-sectional size is 600×800mm (width×height). The beam reinforcement 503 uses 16 threaded steel bars with a diameter of 18mm. The reinforcement diagram is as shown in the figure. Figure 8 As shown), the beam reinforcement 503 of the second horizontal beam 506 is set at the top of the reinforcement height (the design section size is 600×500mm (width×height), and the beam reinforcement adopts 12 threaded steel bars with a diameter of 16mm. The reinforcement diagram is as shown Fig. 9 As shown); stirrups 505 are set with a diameter of 10mm and a spacing of 150mm, and the stirrups 505 are welded to the original steel bars 101.
