[0032] With the continuous development of society, the construction of municipal engineering is also constantly advancing. In municipal engineering, in order to ensure the stability of buildings and roads, slope support is often required. As an effective slope support method, shotcrete technology has been widely used in municipal engineering.

[0033] In municipal engineering, shotcrete technology is mainly used for the construction of municipal retaining piles. Municipal retaining piles are a common foundation pit support structure, mainly used to maintain the stability of the surrounding area of the foundation pit and prevent surface settlement and groundwater leakage. Shotcrete technology can improve the stability of retaining piles and reduce safety accidents during construction. Shotcrete technology has the advantages of low cost, less project land occupation, timely support, fast construction speed, etc., but there are also certain problems in shotcrete construction, such as the safety of construction personnel, the quality problems of concrete caused by untimely feeding, the shotcrete efficiency problems, etc. The common shotcrete construction method is to mix concrete, open the main air valve, start the spraying pump, and manually add concrete to the hopper of the spraying pump. How to solve the safety problems of construction personnel and the quality problems of concrete caused by untimely feeding are problems faced by many technicians.

[0034] During the construction of shotcrete between retaining piles, multiple workers are required to shovel and transport concrete into the feeding trough of the shotcreting machine, and use high-pressure air to spray the concrete to the position between the retaining piles. However, during the feeding process, multiple feeding workers are required to continuously shovel and transport the concrete into the feeding trough of the shotcreting machine. The safety risk is high during the process of workers shoveling and transporting concrete, the labor intensity of the operators is large, the construction cost is high, the work efficiency is low, and the situation of material shortage is likely to occur, which will seriously affect the quality of concrete spraying. In severe cases, the spraying pipe will be blocked and unable to continue, easily causing rework, wasting costs, delaying the construction period, and affecting the construction quality. Therefore, a shotcrete feeding device is studied for the construction of shotcrete between piles, so as to reduce the construction cost of shotcrete between piles and significantly improve the construction efficiency.

[0035] The common construction method of shotcrete involves mixing concrete, opening the main air valve, starting the spraying pump, and manually adding concrete to the hopper of the spraying pump. This is the traditional construction method of shotcrete. However, these construction methods require a large number of operators, are slow, the shotcrete is discontinuous, and it is difficult to control the spraying quality, resulting in rework, cost waste, and project delays. In severe cases, it will affect the construction quality. Therefore, the pile - interval shotcrete construction technology still needs to be further improved and enhanced on the existing technology. Due to the cumbersome construction steps of conventional methods, the consumption of "man, machine, and materials" is large. And because multiple people need to construct simultaneously, the probability of "personal error" increases, further increasing the construction difficulty and resulting in a low efficiency of shotcrete construction.

[0036] To improve the pile - interval shotcrete construction technology, avoid rework, save costs, improve work efficiency, and promote the innovation of pile - interval shotcrete technology, a shotcrete feeding device is developed to solve the problem of difficult feeding during the pile - interval shotcrete construction process. This application mainly simplifies the construction operation steps, thereby streamlining the labor force, reducing material losses, improving work efficiency, and further ensuring the qualification rate of pile - interval shotcrete construction and the safety of personnel operations.

[0037] Reference Figures 1-3 , a shotcrete feeding device provided by this application includes:

[0038] A loading bin 101; a support assembly to which the loading bin 101 is connected for supporting the loading bin 101; a vibration device connected to the loading bin 101; a discharging mechanism provided at the bottom opening of the loading bin 101 for releasing the materials in the loading bin 101; and a filter screen 501 covering the inlet of the loading bin 101.

[0039] In this embodiment, the main process of using this new device is as follows:

[0040] 1. Mix concrete; 2. Load the concrete into the funnel; 3. Turn on the shotcrete equipment; 4. Open the discharging mechanism; 5. Open the vibration device; 6. Spray the concrete. Then continue with the next shotcrete construction process according to the above steps 1 - 6.

[0041] This feeding device mainly consists of a funnel - type loading bin 101, a support assembly, a vibration device, a discharging mechanism, and a filter screen 501.

[0042] (1) Relying on operators to shovel and transport shotcrete, the manual operation efficiency is low, it is easy to cause untimely feeding, resulting in discontinuous shotcrete and a low qualification rate of shotcrete quality. And during the construction process, due to the need for multiple people to cooperate in construction, the personal safety hazards increase, and the safety of personnel cannot be guaranteed.

[0043] (2) Relying on increasing the number of operators or using some common self - made feeding devices, there are often problems such as slow transfer speed and the need for multiple people to cooperate in handling, resulting in low construction efficiency.

[0044] (3) This equipment can effectively avoid problems such as site restrictions, difficulty in deploying construction machinery, high requirements for shotcrete quality, and short construction period requirements. It can effectively improve personnel safety, increase work efficiency, avoid rework and waste of costs. It reduces accidental errors caused by complex processes during construction, simplifies construction steps, reduces construction difficulty, and improves the work efficiency of operators.

[0045] Through the setting of the loading bin 101, the concrete material can be pre-stored in the loading bin 101. At this time, by the discharging device arranged at the bottom of the loading bin 101, the concrete is released evenly, and continuous feeding can be carried out without pausing. The setting of the vibration device can prevent the problem that the concrete in the loading bin 101 adheres to the inner wall and does not fall off. The setting of the filter screen can filter large masses of concrete that adhere together, initially controlling the agglomeration of shotcrete concrete. This device has a simple structure, is convenient for installation and disassembly, has simple and flexible operation, high turnover utilization rate, small workload of operators, can ensure the continuity of shotcrete operations while reducing the number of operators, and can be applied to various sites to ensure construction safety and quality. It reduces construction difficulty, reduces construction consumption, and speeds up the construction progress.

[0046] In some embodiments, the loading bin 101 is funnel-shaped, and the feed inlet of the loading bin 101 is larger than the bottom opening of the loading bin 101.

[0047] The loading bin 101 is welded by 4 Q235 steel plates with a thickness of 5 mm, with a larger upper part and a smaller lower part. The funnel-shaped design facilitates rapid loading during use. The lower part is connected to the discharging device and is used to store shotcrete materials.

[0048] The funnel-shaped loading bin 101 is made of steel plates, but the use of bamboo plywood or iron plates can also achieve the present application.

[0049] In some embodiments, the support assembly includes a vertical support device 201 and a horizontal support device 202. The vertical support device 201 is connected to the corners of the loading bin 101 and extends downward. The horizontal support device 202 is connected to the side of the loading bin 101, and the vertical support device 201 is connected to the horizontal support device 202.

[0050] The vertical support device 201 includes 4 vertical steel pipes, which are respectively connected to the four corners of the loading bin 101 and are vertically arranged.

[0051] The middle part of the vertical steel pipe is also connected with a reinforcing rib 203. The reinforcing rib 203 is made of 4 angle steels of ∠30*3 (equal-angle steel). The transverse support device 202 includes 4 transverse steel pipes, which are respectively connected to the four sides of the charging bin 101. The two ends of the transverse steel pipe on each side of the charging bin 101 are respectively connected to the vertical steel pipes at both ends of each side.

[0052] The bottom of the vertical steel pipe is connected with an end plate 204, which increases the contact area with the ground and improves the structural stability.

[0053] In some embodiments, the vibration device includes a vibration motor 301, and the vibration motor 301 is connected to the outer wall surface of the charging bin 101. This device uses an ADJZ-3 type adjustable vibration motor 301, and the four corners are connected by bolts, which increases the vibration of the bin wall and prevents the material from stagnating. The four corners of the vibration motor 301 are connected to the outer wall of the charging bin 101 by bolts.

[0054] The discharging mechanism is composed of a lever member 401, a cylinder 402, a circular plate 403, and a reel 404. Among them, the lever member 401 is made of a DN32 steel pipe with a length of 60 mm, which plays a lever role to make the circular plate 403 play a better opening and closing role. The cylinder 402 is a stainless steel turned drum, and its upper and lower ends are welded to the reel 404. The lever member 401 and the circular plate 403 are welded to both sides of the shaft body of the circular plate 403. The circular plate 403 is a steel plate with a circular diameter of 50 cm and a thickness of 5 mm, which is used to control the discharging speed. The reel 404 is rolled from a Q235 steel plate with a thickness of 3 mm, with a diameter of 50 cm, and is welded to the bottom surface of the charging bin 101. An 8-mm semi-circular hole is opened in the middle position for the opening and closing of the circular plate 403. The discharging speed is adjusted by the size of the opening of the discharging device. The larger the opening, the faster the discharging speed.

[0055] In some embodiments, the discharging mechanism includes sliding tracks, which are arranged on both sides of the bottom opening of the charging bin 101 and welded to the side wall of the charging bin 101. A rectangular plate is slidably connected to the sliding tracks. A plurality of rectangular holes with different areas are arranged at intervals on the rectangular plate. The rectangular plate fits with the opening. By sliding the rectangular plate, the rectangular holes with different areas can be switched to the opening to form a discharging port.

[0056] In some embodiments, the area of the filter screen 501 is at least twice the area of the feeding port, and the area of the feeding port covered by the filter screen 501 can be alternately replaced by moving the filter screen 501.

[0057] The area of the filtering screen 501 is six times that of the feeding port, the length is three times that of the filtering port, and the width is twice that of the filtering port. Steel bars 502 are welded to both sides and the middle of the bottom of the filtering screen 501. The steel bars 502 are parallel to the long side of the filtering screen 501. Channel steels 503 are welded to both sides of the loading bin 101. The grooves of the channel steels 503 are exactly slidably connected with the steel bars 502, and the two can be disassembled in the up and down direction. The filtering screen 501 can slide on the feeding port. When the filtering screen 501 on one side is blocked after screening a predetermined amount of concrete, the part of the filtering screen 501 on the left and in the middle can be lifted out, and the part on the right and in the middle can be lifted into the feeding port.

[0058] The filtering screen 501 is made by welding a plurality of steel bars vertically and horizontally in a staggered manner, and the hole diameter of the filtering screen 501 is 5 cm.

[0059] As mentioned above, it is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any person skilled in the art in the technical field disclosed by this application can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should be covered within the protection scope of this application.
