Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy construction, and particularly to an auxiliary device for foundation pit pouring in water conservancy and hydropower construction. Background Art

[0002] In the construction of water conservancy and hydropower projects, foundation pit excavation and concrete pouring are the core links of basic construction, and their quality is directly related to the stability and safety of the main structures such as dams and power station buildings. In the traditional foundation pit pouring process, as a key component of the formed concrete structure, the design, installation and removal efficiency of the formwork system have a significant impact on the construction period and cost.

[0003] However, the following technical bottlenecks have gradually emerged in the foundation pit formwork system in the prior art in engineering practice, seriously restricting the improvement of construction efficiency and the optimization of project quality: 1. For the currently widely used steel or wooden integral formwork, in deep foundation pit construction, due to the huge lateral pressure generated by concrete pouring and the extrusion of soil, the formwork is prone to local buckling deformation or even fracture; 2. When assembling the integral formwork on site, multiple workers need to work at height to tighten bolts and calibrate positions. Not only is it difficult to ensure the installation accuracy, but there are also certain potential safety hazards for workers; 3. The size of the monolithic formwork usually matches the designed cross-section of the foundation pit, and large equipment is required for transportation. For special terrains such as narrow mountainous areas or tunnels, the formwork transfer efficiency is low, affecting the operation efficiency. Summary of the Invention

Detailed Embodiment

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0031] Refer to Figure 1 , Figure 10 and Figure 11, A foundation pit pouring auxiliary device for water conservancy and hydropower construction, including symmetrically arranged bases 1 on the left and right. On one side of the upper ends of the two bases 1 close to each other, there is a fixed frame 11 fixedly connected. On the upper end surface of the base 1, a lower formwork 2 is slidably connected left and right. On the side surface of the fixed frame 11, an upper formwork 3 is slidably connected up and down. On the upper ends of the left and right upper formworks 3 close to one side, there are symmetrically arranged in the front and back two groups of connecting components 31. The connecting components 31 are used to connect and support the left and right upper formworks 3. On the connecting components 31, there is an abutting component 32 abutting on the lower formwork 2. On the same group of connecting components 31 and abutting components 32, there is a common auxiliary fixing part 4 connected. The front and back two auxiliary fixing parts 4 are symmetrically arranged. Each auxiliary fixing part 4 is used to synchronously lock the connecting components 31 and abutting components 32 in the same group. On the front and back side surfaces of the lower formwork 2 and the upper formwork 3, there is a locking component 5. The locking component 5 is used to further lock the lower formwork 2 and the upper formwork 3 after they are spliced up and down.

[0032] Before construction, corresponding small stones are pre-filled in the foundation pit to be poured (for details, refer to Figure 11 ). The small stones are respectively laid on the bottom and two side edges of the foundation pit. This is the prior art and will not be elaborated here. First, the upper formwork 3 is correspondingly spliced on the lower formwork 2. The lower formwork 2 and the upper formwork 3 are assembled into a piece of formwork. It should be noted that on the sides of the lower formwork 2 and the upper formwork 3 far from the concrete pouring, there are multiple reinforcing ribs. For the convenience of description, the lower formwork 2 and the upper formwork 3 on the same side are collectively referred to as a single-sided formwork after assembly. At this time, the connecting component 31 is perpendicular to the upper formwork 3, and the abutting component 32 is in an inclined state and abuts on the corresponding side of the lower formwork 2. The auxiliary fixing part 4 locks the upper formworks 3 on both sides, and the locking component 5 further locks the lower formwork 2 and the upper formwork 3 after they are spliced. Use the existing crane to hoist the two symmetrically arranged single-sided formworks into the foundation pit, and insert the far sides of the two bases 1 into the bottom ends of the sides of the pre-laid small stones, which plays a preliminary positioning role for the single-sided formworks on both sides. There is a certain distance between the single-sided formworks on both sides and the small stones laid on both sides of the foundation pit. Later, the concrete will be directly poured between the small stones and the single-sided formworks to form slope protection. When the concrete is formed, release the locking of the connecting component 31, the abutting component 32 and the auxiliary fixing part 4, and use external force to move the single-sided formworks on both sides towards the middle in turn. Pull the bases 1 out of the bottommost small stones, hoist the single-sided formworks on both sides to the position where the next section needs to be poured, and cycle the above operations.

[0033] Refer to Figure 1 and Figure 2 , On the upper end surfaces of the lower formwork 2 and the upper formwork 3, there are symmetrically arranged rectangular grooves in the front and back. In the rectangular grooves, there are hanging ear seats 6 fixedly welded. The height of the hanging ear seats 6 is equal to the depth of the rectangular grooves.

[0034] It should be noted that the ear hanger seat 6 is matched with the hook model of the external hoisting equipment, which facilitates the hoisting operation of the hoisting equipment in both the storage state and the unfolded state. Moreover, the height of the ear hanger seat 6 is equal to the depth distance of the rectangular groove. When the upper template 3 is assembled on the upper end of the lower template 2, the ear hanger seat 6 will not affect the assembly effect.

[0035] Refer to Figure 5 and Figure 6 , on the front and rear symmetry of the upper end surface of the base 1, horizontal chutes 12 are opened. On the left and right sides inside the horizontal chutes 12, arc-shaped slopes are provided. The bottom end of the lower template 2 is fixedly connected with a T-shaped slider 21, and on the left and right sides of the T-shaped slider 21, scraper plates 22 are fixedly connected.

[0036] Since the base 1 needs to be inserted into the pre-laid small stones in the foundation pit during operation in the foundation pit, some of the stones are too small and will enter the horizontal chute 12. And the lower template 2 slides through the T-shaped slider 21. During the sliding process of the T-shaped slider 21, it will drive the scraper plate 22 to shovel out the small stones in the horizontal chute 12 to avoid affecting the normal sliding of the T-shaped slider 21. The scraper plate 22 is made of rubber and has a certain bending force. When the scraper plate 22 contacts the arc-shaped slope, the bottom of the scraper plate 22 will move along the arc-shaped slope, which is convenient for shoveling out the small stones.

[0037] Refer to Figure 7 and Figure 8 , on one side of the fixing frame 11 close to the upper template 3, a vertical chute 111 is opened. On one side of the upper template 3 close to the fixing frame 11, a sliding block 30 is fixedly connected. On the lower part of one side of the upper template 3 close to the fixing frame 11, a docking blind hole is opened. At the lower part of the fixing frame 11, a limiting member 112 is provided. The limiting member 112 includes a limiting through hole 113 opened at the lower end of the fixing frame 11 close to the lower end and a limiting screw 114 threadedly connected in the limiting through hole 113. When the bottom end of the upper template 3 contacts the upper end surface of the base 1, the position of the limiting screw 114 corresponds to that of the docking blind hole.

[0038] The upper template 3 moves up and down through the sliding block 30 in the vertical chute 111 of the fixing frame 11. The highest distance that the upper template 3 moves upward is the height distance of the lower template 2. When the upper template 3 is at the lowermost part of the fixing frame 11 and the bottom end of the upper template 3 is located on the upper end of the base 1, the limiting screw 114 is threaded through the limiting through hole 113 and clamped into the docking blind hole at the lower part of the upper template 3 to lock and limit between the upper template 3 and the fixing frame 11, which is convenient for hoisting the lower template 2 and the upper template 3 simultaneously in the storage state.

[0039] Refer to Figure 1 , Figure 7 and Figure 9, the connecting component 31 includes hinge seats 311 fixedly connected to the relatively close upper ends of the left and right upper templates 3. A connecting rod 312 is hinged to the hinge seat 311, and the other sides of the two connecting rods 312 away from the hinge seat 311 are jointly hinged to the connecting seat 313.

[0040] During transportation, the bottom ends of the lower template 2 and the upper template 3 are both attached to the top end of the base 1, and the height of the single-sided template is halved. At this time, the auxiliary fixing part 4 does not lock the connecting component 31 and the abutting component 32. The connecting seat 313 is located below the top end of the upper template 3 under the action of gravity, and the two bases 1 are in a close state. In this state, it is convenient to transport it to the construction site (specifically refer to Figure 9 the state diagram). After hoisting it into the foundation pit, first assemble the lower template 2 and the upper template 3, and then gradually move the single-sided templates on both sides closer to the two sides of the foundation pit. When the connecting rod 312 and the connecting seat 313 are horizontally arranged with each other, the distance between the two bases 1 on both sides is the largest. The connecting rod 312 plays a role in limiting the single-sided templates on both sides and can also enhance the stability of the single-sided templates.

[0041] Refer to Figure 1 , Figure 3 and Figure 7 , the abutting component 32 includes card-connecting through grooves 321 symmetrically opened on the lower part of the connecting seat 313, a rotating frame 322 clamped in the card-connecting through grooves 321, a fixing screw 323, and an abutting long rod 324 slidably connected to the lower part of the rotating frame 322; a retaining edge is integrally connected to the bottom side of the card-connecting through groove 321; the upper part of the rotating frame 322 is in a rectangular frame structure, and the lower part of the rotating frame 322 is in an inverted U-shaped structure; a fixing screw 323 is movably connected to the limiting hole opened in the middle of the retaining edge, the fixing screw 323 penetrates through the retaining edge and is threadedly connected to the upper part of the rotating frame 322, and an avoidance hole 327 is opened in the lower part of the rotating frame 322, and the abutting long rod 324 is movably connected to the avoidance hole 327. Two symmetrically arranged front and rear clamping seats 20 are jointly provided at the upper ends of the left and right lower templates 2 close to one side. The clamping seat 20 is composed of a U-shaped clamping seat fixedly connected to the lower template 2 and a limiting rod fixedly connected in the U-shaped clamping seat. The opening of the U-shaped clamping seat faces the other lower template 2. The other end of the abutting long rod 324 is clamped and matched with the clamping seat 20, and an arc-shaped notch for cooperating with the clamping seat 20 is opened on the side of the abutting long rod 324 close to the lower template 2.

[0042] When the connecting rod 312 is horizontal relative to the ground, push the abutting long rod 324 upward. While the abutting long rod 324 slides upward in the avoidance hole 327, it rotates toward the corresponding lower template 2 until the end of the abutting long rod 324 close to the lower template 2 rotates above the clamping seat 20, and then rotates downward and pulls downward toward the lower part of the avoidance hole 327, so that the arc-shaped notch on the abutting long rod 324 is clamped and matched with the limiting rod on the clamping seat 20.

[0043] When the fixing screw 323 releases the threaded connection with the rotating frame 322, the rotating frame 322 can be taken out from the clamping through groove 321. During transportation, the rotating frame 322, the fixing screw 323 and the abutting long rod 324 can be transported separately as a whole, avoiding damage to the structure during transportation, and the disassembly and assembly are simple, which is convenient for the later replacement and maintenance of parts.

[0044] Refer to Figure 1 、 Figure 2 and Figure 4 As shown in FIGS.

[0045] The auxiliary fixing part 4 includes a clamping plate 41 clamped on the upper end of the connecting seat 313 and two fixing rods 42 fixedly connected to the bottom end of the clamping plate 41; the clamping plate 41 has an inverted U-shaped structure, and two ear seats for cooperating with the hoisting equipment are correspondingly arranged at the top end of the clamping plate 41. The two fixing rods 42 respectively penetrate through the first connection hole opened on the same side connecting rod 312 and the second connection hole opened on the abutting long rod 324 at the same time. It also includes an auxiliary block 325 fixedly connected to the opposite sides of the two abutting long rods 324, and a through hole corresponding to the second connection hole is opened on the auxiliary block 325.

[0046] Refer to Figure 1 and Figure 2 As shown in FIGS.

[0047] The setting of the locking component 5 further fixes the lower template 2 and the upper template 3 after they are butted up and down. Specifically, when the upper template 3 is butted on the lower template 2, the connecting plate 53 can be rotated into the first notch 51 on the lower template 2, and at the same time, the threaded docking rod 54 is screwed into the docking hole 55. After being screwed tightly, the threaded docking rod 54 is located in the first notch 51, which does not affect the docking between adjacent lower templates 2.

[0048] In an embodiment of the present invention, unless otherwise clearly specified or limited, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "below" and "beneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply indicates that the horizontal height of the first feature is less than that of the second feature.

[0049] In the description of the present invention, it should also be noted that, unless otherwise clearly specified or limited, the terms "arranged", "connected", "installed" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection, or a sliding connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0050] The embodiments of the specific implementation manners are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention should be covered within the protection scope of the present invention.
