[0049] The main body 100 further includes a hydraulic and electrical control system 71, which is connected to the hydraulic drive motor 16, the propulsion cylinder 6 and the cleaning cylinder 5 through hydraulic pipes (not shown). The hydraulic and electrical control system 71 serves as a power source to control the hydraulic drive motor 16, the propulsion cylinder 6 and the cleaning cylinder 5 to work.

[0050] Preferably, the hydraulic and electrical control system 71 can be arranged in the hydraulic and electrical control cabinet 7 .

[0051] See also Figure 4 , Figure 5 In this embodiment, the main body 100 can be arranged on a lining trolley 20, and the lining trolley 20 is divided into four layers: including: a first lining trolley layer 201, a second lining trolley layer 202, a third lining trolley layer 203, and a fourth lining trolley layer 204. The top of the lining trolley 20 is a lining trolley top arch 205; because one end 91 of the S-shaped elbow 15 can be connected to a ground pump, the system of the present invention is turned on, and concrete is transported by the ground pump. At the beginning, the ground pump should transport mortar, and the pipe should be lubricated in advance after the pipe is reversed, so that it is not easy to block the pipe;

[0052] One end of the S-shaped bend pipe 15 is connected to one end of the push pipe 13 through the U-shaped bend pipe 14. The push pipe 13 is pushed to the riser 8 by the push cylinder 6 and connected to the riser 8. The external pipeline of the riser 8 is used to cast the lining trolley. The external pipeline of the riser 8 is an external pipeline.

[0053] Since the annular riser frame 1 is provided with a plurality of risers 8, the propulsion pipe 13 can rotate along with the rotary device 2, and the propulsion pipe 13 can be connected with a plurality of risers to transport concrete. The plurality of risers 8 can be connected with a plurality of external pipelines to cast the lining trolley.

[0054] The system of the present invention casts the lining trolley 20 in the following steps:

[0055] 1. Connect one end 91 of the S-shaped elbow 15 to the ground pump, start the system of the present invention, and operate the propulsion pipe 13 to align with the riser 8 and tighten it.

[0056] 2. Start the ground pump and pump concrete. At the beginning, the mortar should be pumped to ensure that the pipes are lubricated to avoid blockage.

[0057] 3. When the height of the concrete poured on the trolley reaches 50 cm, stop pumping concrete and prepare to pour the next window.

[0058] 4. Lubricate the next external pipeline first (the pipe must be lubricated in place, otherwise it is easy to block the pipe), operate the hydraulic handle, loosen, turn, and then tighten the corresponding next riser pipe.

[0059] 5. Notify the ground pump personnel to continue pumping concrete.

[0060] 6. Repeat steps 2-5 as above to complete the layered concrete pouring. (The above pouring sequence is for reference only, the actual pouring sequence is determined by the on-site construction) During the pouring process, pay attention to lubricate the pipes that will be pumped with concrete in advance. You can use water to lubricate the pipes, or you can use air belts to lubricate the pipes. When tightening the riser, make sure the riser position is clean to prevent the rubber ring from not being pressed tightly, which may cause leakage and blockage. After each layer of pipe pouring is completed, it should be cleaned in time, and the interval time should not be too long.

[0061] In this embodiment, since the main body 100 is further provided with a cleaning head 51 , the cleaning head 51 is pushed to the riser 8 through the cleaning oil cylinder 5 , and the external pipeline can be cleaned through the riser 8 .

[0062] See also Figure 6 ,Should Figure 6 The cleaning system is external to the system of the present invention, and the cleaning system includes a wind and water control system 18, which can control high-pressure wind and water; it also includes an air duct 181, a water pipe 182, a first hose 183, and a second hose 184; the air duct 181, the water pipe 182, the first hose 183, and the second hose 184 are connected to the wind and water control system 18 through a transition joint, the first hose 183 is connected to the cleaning pipe 51, and the second hose 184 is connected to the backwash cleaning pipe 52. The wind and water control system 18 controls the air duct 181, the water pipe 182, the first hose 183, and the second hose 184 to clean the external pipeline and the internal pipeline 19 through the cleaning pipe 51 and the backwash cleaning pipe 52 respectively.

[0063] The steps of cleaning the lining trolley 20 by the system of the present invention are as follows:

[0064] 1. Cleaning: Operate the cleaning head to make the cleaning head 51 rotate with the rotary device 2, and the cleaning head 51 is tightly pressed against the riser 8; first put a cleaning ball inside the cleaning head 51, and then press it against the riser 8, turn on the water and air to operate the cleaning. Wash the concrete in the ground pump pipe into the window of the lining trolley 20, turn off the wind and water, and recycle the cleaning ball. When cleaning, first use the wind to blow the cleaning ball to wash the concrete into the window of the lining trolley 20. After closing the window, rinse it with a small amount of water, so that the outside pipeline is very clean.

[0065] 2. After the pouring of the top arch 205 of the lining trolley is completed, a back-blowing cleaning head is connected to the riser 8 of the empty pipe, a cleaning ball is placed in, and air and water are turned on, so that the concrete inside the system can be cleaned to the ground pump outlet.

[0066] Notes on operating this system:

[0067] 1. During the entire operation, the status of the system and the hose should be observed in time to avoid twisting or tripping.

[0068] 2. Pay attention to cleaning the workplace at ordinary times to prevent material accumulation in the distribution tray.

[0069] 3. Each time the oil cylinder of the system of the present invention is tightened, the oil cylinder is in a self-locking state and the motor of the hydraulic pump station can be stopped, which is helpful for heat dissipation of the hydraulic oil.

[0070] 4. When starting to pour materials, you should first lubricate the pipe with mortar, and then add concrete. Each time before pouring the pipe, you should first moisten the pipe with water, otherwise it will easily cause pipe blockage.

[0071] 5. During the pouring process, the pumping suspension time should not exceed 30 minutes. The ground pump must be started every 30 minutes and pumped 2-3 times to ensure the fluidity of the concrete in the pipe and prevent pipe blockage.

[0072] 6. The clamps at the flange connections of each pipe outlet must be connected and tightened, and the sealing rings must be installed correctly to ensure that there will be no leakage when pumping concrete, otherwise leakage will easily cause pipe blockage.

[0073] The system of the present invention is beneficial in that:

[0074] 1. Reduce labor, reduce labor intensity, and improve labor efficiency. The inner pipe 19 of the material distribution system and the outer pipe 20 of the lining trolley are arranged and installed in advance. There is no need to dismantle or reverse the pipe. The operator controls the distributor to rotate to the corresponding pipe through the electrical switch to cast the lining trolley 20 layer by layer and window by window.

[0075] 2. A fixed pipeline system is arranged in advance on the lining trolley 20. Through the corresponding pipelines, concrete can be poured for four windows on the left and right of the first layer 201 and the second layer 202 of the lining trolley, concrete can be poured for two windows on the left and right of the third layer 203 and the fourth layer 204, and concrete can be poured for two grouting ports at the front and rear of the arch 205.

[0076] 3. Pouring concrete under pressure. Use a material distributor and closed pipeline to pour concrete under pressure, and directly deliver concrete to each window under pressure to avoid material waste and on-site pollution.

[0077] 4. The system has an automatic cleaning function. A hydraulic cylinder is used as the cleaning cylinder 5 to push the cleaning head 51 and open the high-pressure air for cleaning. This changes the disadvantages of the previous inconvenient manual operation, reduces the labor intensity, saves time, and is convenient and fast. After pouring, the head road can be cleaned in time to prevent the occurrence of concrete blocking and other phenomena.

[0078] 5. Realize layered and window-by-window pressure pouring. The layered arrangement of pipelines realizes layered pouring, overcoming the drawbacks of the pouring method of pouring one hole to the bottom, which leads to concrete segregation and herringbone slope cold joints.

[0079] 6. Reduce the design of pipe bends. By changing the structure of the material distributor, the problem of the first generation of automatic pouring system with many elbows and easy pipe blockage has been greatly improved, reducing the troubles of on-site construction workers.

[0080] 7. Satisfy the pouring of each pumping port of the top arch. The first-generation pouring system cannot meet the construction requirements very well. According to the on-site construction experience, the concrete pumping port should be poured as close to the overlapping surface of the secondary lining as possible, and multiple arch pumping ports can be poured. The second-generation equipment can fully meet the construction needs and improve the quality of the secondary lining.

[0081] The split design of the present invention reduces the damage to the hydraulic system and the electrical system caused by pumping shock and vibration, and can also keep the operating part clean, thereby improving the stability and reliability of the product.

[0082] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
