Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of slope protection concrete formwork, in particular to a high fill area slope protection concrete formwork structure. Background Art
[0002] High fill area refers to a fill area that is higher than the surrounding terrain by filling the earth. The fill area is used to prevent waterlogging and waterlogging. A protective levee is formed through the high fill area. During the high fill construction process, the levee formed by the fill is often formed into a slope shape, and the slope design is used to improve the stability of the high fill area.
[0003] After the high fill area is formed, in order to improve the stability of the high fill area and prevent the embankment formed in the high fill area from being washed away by rainwater, especially rainstorms, which may cause landslides and mud-rock flows on the embankment in the fill area, a reinforced embankment structure is currently poured on the embankment in the fill area. For example, a concrete reinforced structure is formed by pouring concrete on the embankment.
[0004] Currently, the most common concrete reinforcement structure is a bow-shaped reinforced concrete structure cast on a concrete protective layer. Specifically, the bow-shaped reinforcement structure forms a bow-shaped support structure on the embankment in the fill area under the support of its bow-shaped structure, thereby solving the occurrence of collapse and mudslides in the fill area.
[0005] During the pouring of the arched concrete structure, the formwork is tilted and laid on the inclined embankment surface. After the concrete is poured, the concrete is subjected to the downward sliding force, which makes it easier for the formwork to expand. The expansion of the formwork not only easily leads to the strength of the poured arched concrete structure failing to meet the standard requirements, but also makes it easy for the concrete structure to penetrate through the gaps between the formworks after the formwork expands, resulting in pouring failure. Especially in construction areas with high inclinations, this situation is more likely to cause the pouring formwork structure to expand, resulting in the failure of the pouring of the arched concrete structure to achieve the expected construction purpose. Utility Model Content
[0006] Based on the above background, the purpose of the utility model is to provide a high fill area slope protection concrete formwork structure.
[0007] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0039] Example 1
[0040] like Figure 1-5 As shown, a high fill area slope protection concrete formwork structure includes a plurality of concrete arched frame formwork mechanisms; the concrete arched frame formwork mechanism installation construction needs to be arranged and installed on the embankment slope of the high fill area slope protection embankment (that is, the concrete arched frame formwork mechanism is inclined). And pour in sequence to form an arched concrete reinforcement structure.
[0041] The specific structure of the concrete arch skeleton formwork mechanism is as follows:
[0042] The concrete arched skeleton formwork mechanism comprises an outer arched formwork 11 and an inner arched formwork 12 located inside the outer arched formwork 11 , and an arched casting cavity is formed between the outer arched formwork 11 and the inner arched formwork 12 .
[0043] The outer arch template 11 and the inner arch template 12 are shaped as follows: both the outer arch template 11 and the inner arch template 12 include an arc portion, and vertical portions are integrally formed on both sides of the arc portion. At the same time, an arch cavity for pouring an arched concrete reinforcement structure is formed between the outer arch template 11 and the inner arch template 12.
[0044] In order to increase the tension between the outer arch formwork 11 and the inner arch formwork 12, the concrete in the arch cavity expands during the pouring process, causing the outer arch formwork 11 and the inner arch formwork 12 to expand, resulting in concrete penetration and leakage, thereby affecting the stability of the pouring structure and causing pouring failure.
[0045] The outer arched template 11 and the inner arched template 12 are assembled and connected via a plurality of tensioning structures; specifically, the tensioning structures are arranged on the side walls of the outer arched template 11 and the inner arched template 12 and are distributed in an arc shape.
[0046] Specifically, the tensioning structure is distributed at the arcuate portions of the outer arcuate formwork 11 and the inner arcuate formwork 12. This method prevents the arcuate portion of the cast arcuate concrete structure from expanding.
[0047] The specific structure of the tensioning structure is as follows:
[0048] The tensioning structure includes bosses 311 respectively fixedly connected to the outer side walls of the outer arch template 11 and the inner arch template 12, and a plurality of tensioning screws 3 are assembled and connected between the bosses 311; the tensioning screws 3 are slidably connected to the bosses, and the two ends of the tensioning screws 311 are threadedly connected to a pair of positioning nuts positioned on both sides of the bosses 311.
[0049] During the working process, after the tensioning screw 3 is passed through between the convex seats, it is locked by the positioning nut, and the outer arched template 11 and the inner arched template 12 are pulled together under the tension of the arc-shaped tensioning screw 3. After the concrete is poured, the outer arched template 11 and the inner arched template 12 are expanded by the concrete, and under the action of the tensioning screw 3, the outer arched template 11 and the inner arched template 12 are not easy to expand from each other.
[0050] At the same time, in order to further prevent the concrete structure from squeezing and expanding the inner arch formwork 12, causing deformation of the poured arched concrete structure, the inner side wall of the inner arch formwork 12 is fixedly connected to an internal support skeleton structure. During the concrete pouring process, the internal support skeleton structure is used to prevent the formwork from expanding and deforming.
[0051] Specifically, the inner support frame structure includes a plurality of transverse support rods 41 fixedly connected between the vertical parts of the inner arched template 12; the transverse support rods 41 are arranged at intervals up and down. At the same time, the inner support frame structure also includes longitudinal support rods 42 threadedly connected between the transverse support rods 41; the top of the longitudinal support rods 42 is supported at the bottom position of the arc-shaped part of the inner arched template 12.
[0052] During the working process, after pouring, the concrete is squeezed into the inner bow formwork 12. At this time, since the inner bow formwork 12 is supported by the transverse support rods 41 and the longitudinal support rods 42 distributed longitudinally form a mesh support structure, the stability of the inner bow formwork 12 is greatly improved and the deformation of the inner bow formwork 12 is avoided.
[0053] Example 2
[0054] like Figure 1-5 As shown, based on the structure of Example 1, the outer arched template 11 and the inner arched template 12 are provided with a template groove A that matches the shape of the outer arched template 11 and the inner arched template 12, and the template groove A includes an arc groove portion and a rectangular groove portion integrally formed with the arc groove portion. At the same time, a plurality of reinforcing rib structures 13 are fixedly connected in the template groove A.
[0055] Specifically, the reinforcing rib structure 13 includes a plurality of first rib plates fixedly connected in the arc-shaped groove portion, wherein the first rib plates are distributed in an arc shape; the reinforcing rib structure also includes a plurality of second rib plates fixedly connected in the rectangular groove.
[0056] In this way, the outer arch formwork 11 and the inner arch formwork 12 are supported from the inside, and under the support, the outer arch formwork 11 and the inner arch formwork 12 are further prevented from deforming after expansion, which causes deformation of the poured arched concrete structure.
[0057] Example 3
[0058] like Figure 1-5 As shown, this embodiment is based on the structure of Embodiment 2, and is the same as the existing construction method, in which all concrete arched skeleton formwork mechanisms are pulled by a plurality of long scaffolding rods 2. The long scaffolding rods 21 are distributed in an up-and-down distribution manner. Specifically, a mounting seat for mounting the long scaffolding rods 2 is welded on the outer arched formwork 11, and the long scaffolding rods 2 penetrate the mounting seat and lock the mounting seat, such as by squeezing the locking nut 21 to lock the positioning method, so as to realize the integrated installation of different concrete arched skeleton formwork mechanisms, form an integral casting structure for casting, and then prevent the concrete arched skeleton formwork mechanism from sliding down and sliding sideways during the casting process.
[0059] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
