Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of slope concrete construction, especially relates to a sectional type rockfill concrete slope concrete formwork structure. BACKGROUND

[0002] Slope construction is an engineering frequently involved in water conservancy projects, and the slope is mostly the dam of the river embankment. If the damaged slope is not maintained and reinforced during the flood occurrence, the slope is prone to collapse under the scouring of the water flow, and the collapse of the river embankment is easily caused.

[0003] The current construction method is sectional construction, and the rockfill concrete is poured on the slope to form a concrete slope protection structure during the construction process. Specifically, the rockfill concrete contains a large amount of concrete and a large amount of gravel as aggregate, so the structural stability of the concrete slope is very high after pouring. Specifically, during the construction process, the formwork needs to be pre-installed on the slope surface, and after the pouring concrete formwork is installed, the rockfill concrete is poured between the formworks in a pouring manner.

[0004] However, during the actual work process, especially during the construction process of the steep slope, the poured concrete has a certain flowability due to the non-drying of the concrete, and under the action of gravity, the rockfill concrete is prone to slide down the slope into the river channel. And with the sliding, the sliding speed gradually increases, and it is difficult to keep the concrete attached to the slope surface during the pouring process.

[0005] The existing formwork structure can only be used as a mold for pouring the concrete model, and cannot appropriately stop the sliding of the concrete aggregate during the work process, so its use is obviously limited, especially when applied to steep slope structures. UTILITY MODEL CONTENTS

[0006] Based on the above background, the purpose of the utility model is to provide a sectional type rockfill concrete slope concrete formwork structure.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0031] 1. During the pouring process, the lower support structure is equipped with baffle plates that cooperate with several pouring templates.

It not only improves the pouring efficiency, but also greatly reduces the pouring difficulty and saves pouring material. Attached Figure Description

[0044] Example 1

[0045] like Figures 1-5 As shown, a segmented riprap concrete slope formwork structure includes several casting formwork 1s cast on the slope. The casting formwork 1s are conventional concrete casting formworks disclosed in the prior art. Specifically, according to the existing formwork locking method, the casting formwork 1s are locked together by several locking structures. The locking structure includes protrusions 21 welded to the top of the casting formwork 1s; long locking bolts 2 are slidably installed between the protrusions 21s; and several positioning nuts, respectively positioned on both sides of the protrusions 21, are threaded onto the long locking bolts 2s.

[0046] The formwork is kept taut by the pulling action of the long locking screw, which aims to prevent the formwork from shifting due to the concrete squeezing it during the pouring process.

[0047] Meanwhile, the lower end of the casting template 1 is hinged with a lower support structure. The specific structure of the lower support structure is as follows: the lower support structure includes a horizontal support part 4, and the top of the horizontal support part 4 is integrally formed with a vertical support part 41.

[0048] The construction process involves pre-drilling trenches at the bottom of the slope and anchoring the lower support structure within the trenches. Alternatively, as is currently done, several anchor rods can be installed on the horizontal support section 4 and driven into the soil structure to achieve fixation.

[0049] Under the action of the lower support structure, the casting formwork 1 is effectively supported.

[0050] The lower end of the above-mentioned casting template 1 is detachably equipped with a lower hinge rod 11, which is hinged to the lower support structure (specifically, a number of lower hinge seats that hinge the lower hinge rod 11 are fixedly connected to the vertical support part 41, and the lower hinge rod 11 is hinged to the lower hinge seat by means of a pin).

[0051] The specific detachable method is as follows: the lower end of the casting template 1 is fixedly connected to the mounting sleeve 12, and the lower hinge rod 11 is sleeved on the mounting sleeve 12; the mounting sleeve 12 is threaded with a locking bolt for locking the lower hinge rod 11 (the lower hinge rod 11 has a through hole (not shown in the figure) that cooperates with the locking bolt). After the mounting sleeve 12 is inserted, the locking bolt passes through the mounting sleeve 12 and the through hole, so as to facilitate the disassembly and fixation of the casting template 1.

[0052] The aforementioned lower support structure is equipped with baffle plates 3 that cooperate with several casting templates 1. During the casting process, the baffle plates 3 obstruct the flow of the riprap concrete. Because the riprap concrete itself contains crushed stone, although it has some fluidity, its fluidity is relatively weak. Under the obstruction of the baffle plates 3, the riprap concrete can be effectively prevented from flowing down the slope during the casting process. This method protects the cast material.

[0053] Specifically, in order to achieve the positioning of the slag baffle 3, the slag baffle 3 has an elongated rectangular opening 31, and the lower hinge rod 11 passes through the elongated rectangular opening 31 (the elongated rectangular opening 31 has a certain length, so it does not affect the rotation of the lower hinge rod 11 within the elongated rectangular opening 31 during the rotation process). A pair of positioning locking nuts 111 are threadedly connected to the lower hinge rod 11 and positioned on both sides of the elongated rectangular opening.

[0054] After the hinge rod 11 is adjusted to an angle (i.e. after the casting template 1 is adjusted to an angle), the locking nut 111 abuts against both sides of the long rectangular opening 11 to achieve positioning of the slag baffle 3 (the locking nut 111 only needs to abut against the slag baffle 3 to form a resisting force).

[0055] By fixing the slag baffle 3 to the pouring template 1 structure in the above manner, the ability of the slag baffle 3 to hold the weight of the concrete is increased, and the technical problem of material slippage is effectively solved during the pouring process. This greatly improves the pouring efficiency while reducing the loss of concrete materials.

[0056] Example 2

[0057] like Figures 1-5 As shown, in this embodiment, based on the structure of embodiment 1, the upper end of the slag baffle 3 is hinged to the side wall (i.e., the front side wall) of the casting template 1, and several upper abutment rod structures are supported on the casting template 1.

[0058] The upper support structure increases the stability of the casting template 1 on the slope, and also increases the stability of the slag baffle 3.

[0059] Specifically, several upper hinge seats are fixedly connected to the upper front side wall of the slag baffle 3. The upper abutment structure includes an upper abutment plate seat 71 hinged to the upper hinge seats. An abutment rod 72 (with a certain depth of abutment rod cavity) that abuts against the casting template 1 is slidably connected to the upper abutment plate seat 71. An abutment rod bolt for positioning the abutment rod 72 is threaded onto the upper abutment plate seat 71. After loosening the bolt of the abutment rod 72, the abutment rod 72 is slidably adjusted until one end of the abutment rod 72 abuts against the template. Then the bolt is tightened. This method achieves pressure on the template to increase the stability of the template, and at the same time, it reinforces and supports the upper end of the slag baffle 3.

[0060] Similarly, the upper outward-facing sidewall of the aforementioned slag baffle 3 is hinged with several support rod structures supported on the lower support structure. Specifically, the support rod structure includes several support hinge seats fixedly connected to the upper rear sidewall of the slag baffle 3; a support adjusting rod is hinged to the support hinge seat. The support adjusting rod includes a hinged support rod 81 (with a threaded cavity of a certain depth), and the support rod 81 is threadedly connected to a lower adjusting rod 82; the horizontal support portion 4 has several rectangular through-holes A that cooperate with the lower adjusting rod 82; the lower adjusting rod 82 passes through the rectangular through-holes A; and the bottom of the lower adjusting rod 82 is threadedly connected to a support nut 821 supported on the horizontal support portion 4.

[0061] During the support process, the lower adjusting rod 82 is adjusted downwards until it passes through the rectangular through-hole A, and then the support nut 821 is adjusted downwards until it is supported on the horizontal support part 4. The purpose of the above structure is that, due to the angle correction adjustment of the slag baffle plate 3, the overall length of the lower adjusting rod 82 and the support rod 81 can be adjusted to ensure support in a vertical position, and the rectangular through-hole A facilitates the movement of the lower adjusting rod 82 within the rectangular through-hole A during the angle correction adjustment of the slag baffle plate 3.

[0062] Example 3

[0063] like Figures 1-5 As shown, in this embodiment, based on the structure of embodiment 1, the upper end of the above-mentioned casting template 1 is hinged with an anchor structure; the anchor structure includes a long anchor 5 hinged to the casting template 1 (specifically, the upper end of the casting template 1 is also fixedly connected to a hinge seat, and a hinge arm 51 is fixedly connected to the long anchor 5, and the hinge arm 51 is hinged to the hinge seat by a pin), and an anchor frame 6 is slidably connected to the long anchor 5, and a plurality of anchor rods 63 anchored to the slope are installed on the anchor frame 6.

[0064] During the work, the anchor rod 63 is driven into the soil layer of the slope to cooperate with the support structure, which will increase the stability of the casting formwork 1.

[0065] The anchor frame 6 has the following shape: it includes a sliding part 61 that is slidably connected to the anchor rod 5 and an anchor plate part 62 integrally formed on the sliding part 61. An anchor rod 63 that can be slidably installed is mounted on the anchor plate part 62. In order to achieve locking after sliding adjustment, the sliding part 61 has a circular structure, and a compression positioning bolt 611 is threadedly connected to the sliding part 61 to achieve positioning of the sliding part 61 by compression positioning.

[0066] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
