Description

Technical Field

[0001] This utility model relates to the field of quick-release formwork technology, and in particular to a quick-release formwork for micro-hole cast-in-place piles in desert and grassland areas. Background Technology

[0002] When constructing micro-hole cast-in-place piles in sandy soil, such as desert photovoltaic and grassland photovoltaic projects, it is necessary to first drill a grouting hole on the ground, then lower the steel cage into the grouting hole, and finally pour concrete into the grouting hole to complete the construction of the micro-hole cast-in-place pile, providing good support for the subsequent construction of photovoltaic brackets.

[0003] In the existing technology, during the construction of micro-hole cast-in-place piles, the soil in desert or grassland areas is relatively loose due to its lack of cohesion. When placing the steel cage or pouring concrete, the sand around the hole will be disturbed, causing the hole to collapse easily and become blocked by sand.

[0004] Therefore, a quick-release formwork for microporous cast-in-place piles in desert and grassland areas is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that when placing the reinforcing cage or pouring concrete, the sand around the hole will be disturbed, causing the hole opening to easily collapse. Therefore, a quick-release formwork for micro-hole cast-in-place piles in desert and grassland areas is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a quick-release template for micro-hole cast-in-place piles in desert and grassland areas, comprising a first set of plates, a second set of plates, and two casings. A semi-circular plate is fixedly mounted on the surface of the casing, and an arc-shaped hole is opened on the surface of the semi-circular plate. A reinforcing plate is fixedly mounted on the surface of both the first set of plates and the second set of plates. An anchor rod slides through the reinforcing plate and slides through the arc-shaped hole. A limit ring is fixedly mounted on the circumferential surface of the anchor rod.

[0007] The effect achieved by the above components is as follows: by setting up components such as the casing, the first plate, the second plate, the semi-circular plate and the anchor rod, when micro-hole grouting piles are constructed in desert and grassland areas, the casing and the semi-circular plate can support and reinforce the opening of the grouting hole, thereby preventing the opening of the grouting hole from collapsing during subsequent construction.

[0008] Preferably, the lower end of the anchor rod has an inclined surface.

[0009] The effect achieved by the above components is that by setting a slope at the lower end of the anchor rod, the resistance when the anchor rod is inserted into the ground can be reduced.

[0010] Preferably, an auxiliary ring is fixedly fitted on the circumferential surface of the anchor rod, and the limiting ring is located between the auxiliary ring and the semi-circular plate.

[0011] The effect achieved by the above components is that after the cast-in-place pile is formed, the anchor rod is pulled upward with the help of the auxiliary ring, and the anchor rod is pulled out from the ground.

[0012] Preferably, a screw is fixedly mounted on the outer circumferential surface of the second sleeve plate, and a U-shaped plate is fixedly mounted on the outer circumferential surface of the first sleeve plate. A nut is threaded onto the circumferential surface of the screw, and the nut abuts against the surface of the U-shaped plate.

[0013] The effect achieved by the above components is as follows: when the nut is put on the screw and rotated, when the nut abuts against the surface of the U-shaped plate, the nut and the screw will restrict the position of the first and second plates.

[0014] Preferably, a clamping plate is fixedly mounted on the surface of the semicircular plate, and a groove adapted to the clamping plate is formed on the surface of the semicircular plate.

[0015] The effect achieved by the above components is that the card plate on the surface of one semicircular plate is embedded into the slot on the surface of another semicircular plate. The slot and the card plate cooperate to connect the two semicircular plates, thereby preventing the two protective cylinders from moving horizontally and losing contact.

[0016] Preferably, two positioning rods are fixedly mounted on the lower surface of the semicircular plate.

[0017] The effect achieved by the above components is that the movement of the semicircular plate will cause the positioning rod to insert into the ground, and the positioning rod will restrict the position of the semicircular plate.

[0018] Preferably, two cylindrical blocks are fixedly assembled on the lower surface of the reinforcing plate, and the cylindrical blocks are slidably connected to the arc-shaped hole.

[0019] The effect achieved by the above components is that the cylindrical block and the arc-shaped hole can restrict the position of the reinforcing plate, thereby facilitating the subsequent insertion of the anchor rod through the reinforcing plate and the arc-shaped hole.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In this invention, by setting up components such as a protective sleeve, a first sleeve plate, a second sleeve plate, a semi-circular plate, and an anchor rod, when constructing micro-hole cast-in-place piles in desert and grassland areas, the protective sleeve and the semi-circular plate can work together to support and reinforce the opening of the grouting hole, thereby preventing the opening of the grouting hole from collapsing during subsequent construction.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] like Figures 1-4 As shown, this utility model provides a quick-release template for micro-hole cast-in-place piles in desert and grassland areas, including a first sleeve plate 2, a second sleeve plate 3, and two casings 1. A semi-circular plate 4 is fixedly mounted on the surface of the casing 1, and an arc-shaped hole 5 is formed on the surface of the semi-circular plate 4. A reinforcing plate 6 is fixedly mounted on the surface of both the first sleeve plate 2 and the second sleeve plate 3. An anchor rod 7 slides through the reinforcing plate 6, passing through the arc-shaped hole 5. A limit ring 8 is fixedly mounted on the circumferential surface of the anchor rod 7. Through the arrangement of components such as the casing, the first sleeve plate 2, the second sleeve plate 3, the semi-circular plate 4, and the anchor rod 7, When constructing micro-hole cast-in-place piles in desert and grassland areas, the casing 1 and the semi-circular plate 4 work together to support and reinforce the opening of the grouting hole, thereby preventing the opening of the grouting hole from collapsing during subsequent construction. The lower end of the anchor rod 7 is provided with an inclined surface, which reduces the resistance when the anchor rod 7 is inserted into the ground. An auxiliary ring 12 is fixedly installed on the circumference of the anchor rod 7, and a limiting ring 8 is located between the auxiliary ring 12 and the semi-circular plate 4. After the cast-in-place pile is formed, the anchor rod 7 is pulled upward with the help of the auxiliary ring 12 to pull the anchor rod 7 out of the ground.

[0030] A screw 9 is fixedly mounted on the outer circumference of the second plate 3, and a U-shaped plate 10 is fixedly mounted on the outer circumference of the first plate 2. A nut 11 is threaded onto the circumference of the screw 9, and the nut 11 abuts against the surface of the U-shaped plate 10. When the nut 11 is put on the screw 9 and rotated, the nut 11, when it abuts against the surface of the U-shaped plate 10, will restrict the position of the first plate 2 and the second plate 3 by engaging with the screw 9. A retaining plate 13 is fixedly mounted on the surface of the semicircular plate 4, and a retaining groove 14 adapted to the retaining plate 13 is opened on the surface of the semicircular plate 4. The retaining plate 13 on the surface of one semicircular plate 4 is inserted into the other. The slot 14 on the surface of the semicircular plate 4, in cooperation with the plate 13, can connect the two semicircular plates 4, thereby preventing the two protective cylinders 1 from moving horizontally and losing contact. Two positioning rods 15 are fixedly installed on the lower surface of the semicircular plate 4. When the semicircular plate 4 moves, the positioning rods 15 will insert into the ground, and the positioning rods 15 will restrict the position of the semicircular plate 4. Two cylindrical blocks 16 are fixedly installed on the lower surface of the reinforcing plate 6. The cylindrical blocks 16 are slidably connected with the arc-shaped hole 5. The cylindrical blocks 16 and the arc-shaped hole 5 can restrict the position of the reinforcing plate 6, thereby facilitating the subsequent insertion of the anchor rod 7 through the reinforcing plate 6 and the arc-shaped hole 5.

[0031] The overall working principle is as follows: When micro-hole cast-in-place pile construction is required in desert or grassland areas, firstly, the clamping plate 13 on the surface of one semi-circular plate 4 is embedded into the groove 14 on the surface of another semi-circular plate 4. The groove 14 and the clamping plate 13 cooperate to connect the two semi-circular plates 4, thereby preventing the two casings 1 from moving horizontally and losing contact. Then, the two casings 1 are inserted into the grouting hole. At this time, the casings 1 and the semi-circular plates 4 cooperate to support and reinforce the opening of the grouting hole, thereby preventing the opening of the grouting hole from collapsing during subsequent construction. The movement of the semi-circular plates 4 will cause the positioning rod 15 to insert into the ground, and the positioning rod 15 will restrict the position of the semi-circular plates 4. Then, the reinforcing cage is placed into the grouting hole through the two casings 1. Then, the first set of plates 2 and the second set of plates 3 are rotated to fit around the reinforcing cage. At this time, the screw 9 will move into the U-shaped plate 10. Then, the nut 11 is put on the screw 9 and rotated. When the nut 11 abuts against the U-shaped plate 10, the screw 9 moves into the U-shaped plate 10. After the surface of the template 10 is completed, the nut 11 and the screw 9 will restrict the position of the first template 2 and the second template 3, thus reinforcing the first template 2 and the second template 3. Then, the first template 2 and the second template 3 are moved downwards, which will drive the reinforcing plate 6 to move, so that the reinforcing plate 6 abuts against the surface of the semi-circular plate 4 and aligns with the arc-shaped hole 5. At this time, the cylindrical block 16 will be inserted into the arc-shaped hole 5. The cylindrical block 16 and the arc-shaped hole 5 can restrict the position of the reinforcing plate 6, thus facilitating the subsequent insertion of the anchor rod 7 through the reinforcing plate 6 and the arc-shaped hole 5. After that, the anchor rod 7 is inserted into the ground through the reinforcing plate 6 and the arc-shaped hole 5. By setting a slope at the lower end of the anchor rod 7, the resistance when the anchor rod 7 is inserted into the ground can be reduced. The movement of the anchor rod 7 will drive the movement of the limiting ring 8. When the limiting ring 8 abuts against the surface of the reinforcing plate 6, it will restrict the position of the reinforcing plate 6 and the semi-circular plate 4, and thus restrict the position of the first template 2 and the second template 3. After the template assembly is completed, the pouring construction of the cast-in-place pile can be carried out normally.

[0032] After the cast-in-place pile is formed, the anchor rod 7 is pulled upward with the help of the auxiliary ring 12 to pull the anchor rod 7 out of the ground. Then, the nut 11 is unscrewed from the circumference of the screw rod 9. Then, the first plate 2 and the second plate 3 can be removed. Then, the semi-circular plate 4 is pulled upward to pull the casing 1 out of the grouting hole, thereby completing the purpose of quickly disassembling the template.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
