Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to an auxiliary device for pouring special-shaped foundation pit supporting cast-in-place piles. Background Technique

[0002] In geotechnical engineering, a building foundation pit refers to the space below the ground excavated for the construction of building foundations and basements. A temporary pit dug for building foundations is called a foundation pit. A foundation pit belongs to a temporary project, and its function is to provide a space so that the masonry operation of the foundation can be carried out at the position specified by the design. A special-shaped foundation pit usually refers to a foundation pit with an irregular shape, and such a foundation pit generally needs to be built with foundation pit support to reinforce the stability of the foundation pit structure and facilitate the normal progress of the construction process.

[0003] When constructing support cast-in-place piles in the foundation pit environment, it mainly includes vibro cast-in-place piles and bored cast-in-place piles. Among them, bored cast-in-place piles generally use a rotary drilling rig to drill. During the drilling process, the inner wall of the pile hole is reinforced with slurry for wall protection. After the hole is formed, a steel reinforcement cage is lowered, and then the pile hole is poured and formed by a concrete pump truck using a pump pipe.

[0004] The above-mentioned prior art has obvious beneficial effects, but there are still deficiencies:

[0005] When the above-mentioned prior art uses a pump truck to carry out the pouring operation of the support piles in the foundation pit, due to the environmental factors of the special-shaped foundation pit, its internal shape is irregular, and the structure of the pump pipe is relatively straight. When pouring the pile hole in the foundation pit, it is easy to be affected by the foundation pit environment, resulting in the outlet of the pump pipe not being able to be aligned with the pile hole, thus seriously affecting the pouring operation. For this reason, an auxiliary device for pouring special-shaped foundation pit supporting cast-in-place piles is proposed. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides an auxiliary device for pouring special-shaped foundation pit supporting cast-in-place piles. By aligning the pump pipe of the pump truck with the hopper plate and cooperating with two groups of adjusting and rotating structures connected to the bottom end of the hopper plate, multi-end adjustment and angle adjustment are formed, playing a role in assisting pouring and feeding in a narrow or special-shaped environment.

[0007] To achieve the above object, the utility model provides the following technical solution: an auxiliary device for pouring special-shaped foundation pit supporting cast-in-place piles, including a frame body, the top end of the frame body is connected with an adjusting frame, and the top end of the adjusting frame is connected with a pouring frame. The pouring frame includes a pouring pipe, and a flange ring is arranged at the bottom end of the pouring pipe. The top end of the pouring pipe is connected with a flexible pipe, and the top end of the flexible pipe is connected with a connecting pipe. Structural frames are connected to both sides of the connecting pipe, and a motor shaft is arranged in the middle of the structural frames. The top end of the connecting pipe is communicated with a hopper plate, and a support rod is connected to the bottom end of the hopper plate.

[0008] Preferably, the pouring pipe is connected to the connecting pipe through a hose, and the top of the connecting pipe is connected to the bottom of the hopper plate through a second set of hoses and the connecting pipe.

[0009] Preferably, the pouring pipe and the connecting pipe are connected by structural frames on both sides, and the hose is connected up and down in a corrugated shape.

[0010] Preferably, the frame body comprises a ring frame, and a universal wheel is installed at the bottom end of the ring frame, a base ring is arranged on the outer wall around the ring frame, and bolts are distributed around the base ring, and the top end of the ring frame is welded to the casting frame.

[0011] Preferably, the base ring is fixedly connected to the bottom ends of the ring frame, and the plugs are arranged around the base ring.

[0012] Preferably, the adjustment frame includes a feeding pipe, and a bearing frame is sleeved around the feeding pipe. A connecting strip is fixed to the outer wall of the bearing frame, and the bottom end of the connecting strip is welded and fixed to the top end of the ring frame.

[0013] Preferably, the feeding pipe is rotatably matched with the bearing frame, and the connecting strip is welded and fixed to the outer wall around the bearing frame.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. After the utility model completes its own movement, its bottom end can be aligned with the pouring pile hole, and the bottom end of the pouring pipe is connected to the feeding pipe through a flange ring to maintain a stable connection. The top hopper plate is adjusted through the two sets of connecting pipes and hoses at the bottom to adjust the conveying angle, and the motor shafts on both sides of the hose and connecting pipe are rotated to adjust the angle. Therefore, under the special-shaped foundation pit, the angle and shape can be adjusted to provide assistance for the pump truck's pump pipe pouring angle, effectively increasing the construction efficiency in the special-shaped foundation pit environment.

[0016] 2. When using this pouring auxiliary device, the whole equipment can be moved through the universal wheels connected to the bottom of the ring frame. When it is moved to the pouring pile mouth, four sets of bolts are inserted into the bottom of the ring frame for positioning to avoid displacement or shaking during use and improve stability during use.

[0017] 3. The center of the feeding pipe of this pouring auxiliary device is aligned with the center of the ring frame, so that the transported concrete material can be stably placed in the pile hole moved by the ring frame, and the feeding pipe itself can be rotated through the bearing frame to adjust the angle of the top connection pouring frame, which is convenient for adjustment and use in special-shaped foundation pits.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , an auxiliary device for pouring special-shaped foundation pit retaining cast-in-place piles in this embodiment, includes a frame body 1. The top end of the frame body 1 is connected with an adjusting frame 2, and the top end of the adjusting frame 2 is connected with a pouring frame 3. The frame body 1 includes a ring frame 101, and universal wheels 102 are installed at the bottom end of the ring frame 101. The outer walls of the four sides of the ring frame 101 are provided with a base ring 103, and bolts 104 are distributed around the base ring 103. The top end of the ring frame 101 is welded to the pouring frame 3.

[0026] As Figure 1As shown in the figure, the pouring aid in the present utility model is similar to the existing tower crane hopper structure. The main improvement of the present utility model is that by aligning the hopper tray 307 with the pump pipe of the concrete pump truck, and cooperating with the two sets of adjustment and rotation structures connected to the bottom end of the hopper tray 307, multi-end adjustment and angle adjustment are formed, which plays a role in assisting pouring and feeding in narrow or special-shaped environments; the hopper tray 307 and the flange ring 302 in the present utility model are both prior arts. When using this pouring aid, the overall equipment can be moved through the universal wheels 102 distributed at the bottom end of the ring frame 101. When moving to the pouring pile opening, the four sets of bolts 104 are inserted into the bottom end of the ring frame 101 for positioning to avoid displacement or shaking during use and improve the stability during use.

[0027] As Figure 2 shown, the adjustment frame 2 includes a feeding pipe 201, and a bearing frame 202 is sleeved around the feeding pipe 201. A connecting strip 203 is fixed to the outer wall of the bearing frame 202, and the bottom end of the connecting strip 203 is welded and fixed to the top end of the ring frame 101. The center of the feeding pipe 201 of this pouring aid is aligned with the center of the ring frame 101, so that the conveyed concrete material can be stably placed into the pile hole where the ring frame 101 moves. The feeding pipe 201 itself can rotate through the bearing frame 202, thereby realizing the angle adjustment of the pouring frame 3 connected to the top end, which is convenient for adjustment and use in special-shaped foundation pits.

[0028] As Figures 3-4 shown, the pouring frame 3 includes a pouring pipe 301, and a flange ring 302 is provided at the bottom end of the pouring pipe 301. A hose 303 is connected to the top end of the pouring pipe 301, and a connecting pipe 304 is connected to the top end of the hose 303. Structural frames 305 are connected to both sides of the connecting pipe 304, and a motor shaft 306 is provided in the middle of the structural frames 305. The top end of the connecting pipe 304 communicates with a hopper tray 307, and a support rod 308 is connected to the bottom end of the hopper tray 307. After this aid completes its own movement, its bottom end is aligned with the pouring pile hole. The bottom end of the pouring pipe 301 is docked with the feeding pipe 201 through the flange ring 302 to maintain stable connection. The hopper tray 307 at the top end is adjusted for the conveying angle through the two sets of connecting pipes 304 and hoses 303 at the bottom end, and the angle is adjusted by rotating the motor shafts 306 on both sides of the hose 303 and the connecting pipe 304. Thus, in a special-shaped foundation pit, through angle and shape adjustment, it can provide assistance for the pouring angle of the pump pipe of the concrete pump truck, effectively increasing the construction efficiency in the special-shaped foundation pit environment. The hopper tray 307 maintains the firm connection angle with the connecting pipe 304 through the surrounding support rods 308, reducing the weight imbalance generated when the concrete is poured during the auxiliary pouring process and further improving the stability.
