[0002] In the construction of water conservancy and hydropower projects, foundation pit excavation and concrete pouring are core steps in foundation construction, and their quality directly impacts the stability and safety of major structures such as dams and power station buildings. In traditional foundation pit pouring processes, the formwork system is a key component of the formed concrete structure, and its design, installation, and removal efficiency significantly impact construction time and costs.

[0003] However, the foundation pit formwork system in the existing technology has gradually exposed the following technical bottlenecks in engineering practice, which seriously restricts the improvement of construction efficiency and the optimization of project quality: 1. The currently widely used steel or wooden integral formwork is prone to local buckling and deformation or even breakage during deep foundation pit construction due to the huge lateral pressure generated by concrete pouring and soil squeezing; 2. When assembling the integral formwork on site, multiple workers are required to work at high altitude to tighten the bolts and calibrate the position. Not only is the installation accuracy difficult to ensure, but there are also certain hidden dangers to worker safety; 3. The size of the integral formwork usually matches the designed section of the foundation pit, and large equipment is required for transportation.

DETAILED DESCRIPTION

[0030] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described below, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] See Figure 1 、 Figure 10 and Figure 11The cam 32 is a kind of symmetrical cam 32 of the left and right sides, and the cam 32 of the right and left sides is used for the cam 32 of the left and right sides.

[0032] Before construction, fill the foundation pit where pouring is required with corresponding small stones (see Figure 11 ), small stones are laid on the bottom and two sides of the foundation pit respectively. This is the existing technology and will not be described in detail 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 formwork. It should be noted that the lower formwork 2 and the upper formwork 3 are both provided with multiple reinforcing ribs on the side away from the concrete pouring. For the convenience of description, the lower formwork 2 and the upper formwork 3 on the same side are collectively referred to as single-sided formwork after assembly. At this time, the connecting component 31 is vertical to the upper formwork 3, and the abutting component 32 is inclined to abut on the lower formwork 2 on the corresponding side. The auxiliary fixing part 4 locks the upper templates 3 on the left and right sides, and the locking component 5 further locks the lower template 2 and the upper template 3 after splicing them together. The existing crane is used to lift the two symmetrically arranged single-sided templates on the left and right into the foundation pit, and the side of the base 1 on both sides that is far away from each other is correspondingly inserted into the bottom end of the side where the pebbles have been laid, which plays a role in preliminary positioning of the single-sided templates on both sides. There is a certain distance between the single-sided templates on both sides and the pebbles laid on both sides of the foundation pit. Later, concrete will be poured directly between the pebbles and the single-sided templates to form slope protection. When the concrete is formed, the locking of the connecting component 31, the abutting component 32 and the auxiliary fixing part 4 is released, and the single-sided templates on both sides are successively brought closer to the middle with the help of external force. The base 1 is pulled out from the pebbles at the bottom, and the single-sided templates on both sides are simultaneously lifted to the position where the next section needs to be poured, and the above operation is repeated.

[0033] See Figure 1 and Figure 2 The upper end surfaces of the lower template 2 and the upper template 3 are both provided with front-to-back symmetrical rectangular grooves, in which the ear mounts 6 are fixedly welded. The height of the ear mounts 6 is equal to the depth of the rectangular grooves.

[0034] It should be noted that the ear mount 6 matches the hook model of the external lifting equipment, which facilitates lifting operations of the lifting equipment in both the stored and unfolded states, and the height of the ear mount 6 is equal to the depth of the rectangular groove. When the upper template 3 is assembled on the upper end of the lower template 2, the ear mount 6 will not affect the assembly effect.

[0035] See Figure 5 and Figure 6 A horizontal slide 12 is symmetrically provided on the front and rear ends of the upper end face of the base 1. Arc-shaped slopes are provided on the left and right sides of the interior of the horizontal slide 12. A T-shaped slider 21 is fixedly connected to the bottom end of the lower template 2. A shovel plate 22 is fixedly connected to the left and right sides of the T-shaped slider 21.

[0036] When the base 1 is working in the foundation pit, it needs to be inserted into the small stones pre-laid in the foundation pit. Some stones are too small and will enter the horizontal slide groove 12. 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 shovel plate 22 to shovel out the small stones in the horizontal slide groove 12 to avoid affecting the normal sliding of the T-shaped slider 21. The shovel plate 22 is a rubber product with a certain bending force. When the shovel plate 22 contacts the curved slope, the bottom of the shovel plate 22 will move along the curved slope to facilitate the shoveling out of the small stones.

[0037] See Figure 7 and Figure 8 A vertical slide groove 111 is provided on the side of the fixing frame 11 close to the upper template 3, and a sliding block 30 is fixedly connected to the side of the upper template 3 close to the fixing frame 11. A docking blind hole is provided on the lower part of the upper template 3 close to the fixing frame 11, and a limiting member 112 is provided at the lower part of the fixing frame 11. The limiting member 112 includes a limiting through hole 113 provided on the fixing frame 11 near the lower end and a limiting screw 114 connected to the inner thread of the limiting through hole 113. When the bottom end of the upper template 3 contacts the upper end surface of the base 1, the limiting screw 114 corresponds to the position of the docking blind hole.

[0038] The upper template 3 moves up and down in the vertical slide groove 111 of the fixed frame 11 through the sliding block 30. The maximum distance the upper template 3 moves upward is the height distance of the lower template 2. When the upper template 3 is at the lowest part of the fixed frame 11 and the bottom end of the upper template 3 is located at the upper end of the base 1, the limit screw 114 is threaded through the limit through hole 113 and is clamped into the docking blind hole at the lower part of the upper template 3 to lock and limit the upper template 3 and the fixed frame 11, so that the lower template 2 and the upper template 3 can be hoisted at the same time in the storage state.

[0039] See Figure 1 、 Figure 7 and Figure 9The connecting component 31 includes a hinged seat 311 fixedly connected to the upper end of the left and right upper templates 3 on opposite sides. A connecting rod 312 is hinged on the hinged seat 311, and the two connecting rods 312 are hinged on the connecting seat 313 on the side away from the hinged seat 311.

[0040] During transportation, the bottom ends of the lower template 2 and the upper template 3 are both attached to the top of the base 1, and the height of the single-side template is halved. At this time, the auxiliary fixing portion 4 does not lock the connecting component 31 and the abutting component 32. The connecting seat 313 is located below the top of the upper template 3 under the action of gravity. The two bases 1 are in a close state. In this state, it is easy to transport them to the construction site (see details). Figure 9 State diagram), after being hoisted into the foundation pit, the lower template 2 and the upper template 3 are assembled first, and then the single-sided templates on both sides are gradually moved close to the two sides of the foundation pit. When the connecting rod 312 and the connecting seat 313 are set in a mutually horizontal state, the distance between the 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] See Figure 1 、 Figure 3 and Figure 7 When the handle 321 is in the unlock position, the lever 324 is locked and the locking lever 326 is locked, so that the locking lever 326 can be locked in the unlock position when the lever 326 is unlocked. The upper ends of the left and right lower templates 2 are both equipped with two symmetrical front-to-back mountings 20. These mountings 20 consist of a U-shaped mounting fixedly connected to the lower template 2 and a limiting rod fixedly connected within the U-shaped mounting. The opening of the U-shaped mounting faces the lower template 2 on the other side. The other end of the abutting rod 324 engages with the mountings 20. The side of the abutting rod 324 near the lower template 2 has an arc-shaped notch that mates with the mountings 20.

[0042] When the connecting rod 312 is horizontal relative to the ground, the abutting long rod 324 is pushed upward, and the abutting long rod 324 slides upward in the avoidance hole 327 and rotates toward the corresponding lower template 2 until the abutting long rod 324 rotates to the top of the clamping seat 20 near one end of the lower template 2, and then rotates downward and pulls toward the bottom of the avoidance hole 327, so that the arc-shaped notch on the abutting long rod 324 is engaged with the limit rod on the clamping seat 20.

[0043] When the fixing screw 323 releases the threaded connection to the rotating frame 322, the rotating frame 322 can be removed from the card slot 321. During transportation, the rotating frame 322, the fixing screw 323 and the abutting long rod 324 can be transported separately as a whole to avoid structural damage during transportation. The assembly and disassembly are simple, which facilitates the later replacement and maintenance of parts.

[0044] See Figure 1 、 Figure 2 and Figure 4 The auxiliary fixing portion 4 includes a clamping plate 41 clamped to the upper end of the connecting seat 313 and two fixing rods 42 fixedly connected to the lower end of the clamping plate 41. The clamping plate 41 has an inverted U-shaped structure, with two ears at the top corresponding to the lifting equipment. The two fixing rods 42 respectively pass through the first connecting hole defined in the connecting rod 312 and the second connecting hole defined in the abutting rod 324 on the same side. It also includes an auxiliary block 325 fixedly connected to the opposite sides of the two abutting rods 324. The auxiliary block 325 has a through hole corresponding to the second connecting hole.

[0045] The auxiliary fixing part 4 is provided to further lock the connecting component 31 and the abutting component 32. First, the clamping plate 41 is hoisted to the top of the connecting seat 313 by the hoisting equipment and clamped on the connecting seat 313. At the same time, the fixing rod 42 will simultaneously pass through the first connecting hole opened on the connecting rod 312 on the same side and the second connecting hole opened on the abutting long rod 324 to limit and lock the connecting component 31 and the abutting component 32; and the auxiliary block 325 provided on the abutting long rod 324 facilitates the threaded locking of the bottom end of the fixing rod 42 through a nut to enhance the overall stability.

[0046] See Figure 1 and Figure 2 The locking assembly 5 includes a first notch 51 opened at the upper end of the side surface of the lower template 2, a second notch 52 opened at the lower end of the side surface of the upper template 3, a connecting plate 53 rotatably connected to the second notch 52, a threaded docking rod 54 threadedly connected to the connecting plate 53, and a docking hole 55 opened in the first notch 51; the first notch 51 and the second notch 52 are arranged correspondingly, and the first notch 51 and the second notch 52 form a rectangular groove structure.

[0047] The setting of the locking assembly 5 enables the lower template 2 and the upper template 3 to be further fixed after being docked up and down. Specifically, when the upper template 3 is docked on the lower template 2, the connecting plate 53 can be rotated to the first notch 51 on the lower template 2, and the threaded docking rod 54 can be tightened to enter the docking hole 55 at the same time. After tightening, the threaded docking rod 54 is located in the first notch 51 and does not affect the docking between adjacent lower templates 2.

[0048] In the embodiments of the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediary. Furthermore, a first feature being "above," "above," or "above" a second feature may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. A first feature being "below," "below," or "below" a second feature may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0049] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "connected," "installed," and "connected" should be understood broadly. For example, they may refer to fixed or detachable connections, integral or sliding connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0050] The embodiments of this specific implementation method are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
