The method comprises the steps of closing a valve III (1003), a valve IV (1004), a valve VIII (1008) and a valve XII (1012), opening other valves, starting the paver, enabling a stirrer (3) to rotate firstly and rotate anticlockwise to stir cement paste mixtures, restarting a screw pump (2), enabling the cement paste to be sucked into a pump body by the screw pump (2), sequentially passing through a pipeline 901 and a pipeline 902 II, dividing the connection part of the pipeline 902 II and the pipeline 903 III into two paths, enabling one path of the cement paste to enter a cement box 1 through a valve 1001I and to be discharged out of the bottom of the cement box 1 through a first return pipe 1301, enabling the other path of the cement paste to be divided into two paths after passing through the pipeline 903 II, enabling one path of the cement paste to enter the cement box 1 through a valve II (1002) and to be discharged out of the bottom of the cement box 1 through a return pipe 1303), and enabling the other path of the cement paste to sequentially pass through a pipeline 905, a pipeline II, The sixth pipeline (906), the first hose (1201), the first spray pipe (1101), the second hose (1202), the second spray pipe (1102), the third hose (1203), the third spray pipe (1103), the fourth hose (1204), the seventh pipeline (907) and the eighth pipeline (908) are divided into two paths, one path enters the cement box (1) through an X valve (1010) and is discharged out of the bottom of the flushed cement box (1) through a second return pipe (1302), the other path sequentially passes through a ninth pipeline (909) and a XI valve (1011) and then is discharged out of the bottom of the flushed cement box (1) through a fourth return pipe (1304), and the circulation is continuous, so that the first spray pipe (1101) and the third spray pipe (1103) are ensured to uniformly and uninterruptedly spray cement slurry to the adjacent side subgrade (8) respectively, meanwhile, the second spraying pipe (1102) is opposite to the middle roadbed (7) and sprays cement slurry continuously and uniformly;
s202. front spraying does not work and side spraying works at the same time
The method comprises the steps of closing a valve III (1003), a valve IV (1004), a valve VI (1006), a valve VII (1007) and a valve XII (1012), opening other valves, starting the paver, firstly rotating a stirrer (3), stirring a cement slurry mixture by anticlockwise rotating, restarting a screw pump (2), sucking the cement slurry into a pump body by the screw pump (2), sequentially passing through a pipeline I (901) and a pipeline II (902), dividing the joint of the pipeline II (902) and a pipeline III (903) into two paths, allowing one path of the cement slurry to enter a cement box (1) through the valve I (1001) and be discharged through a first return pipe (1301) to flush the bottom of the cement box (1), allowing the other path of the cement slurry to be divided into two paths after passing through the pipeline III (903), allowing the other path of the cement slurry to enter the cement box (1) through the valve II (1002) and be discharged through a third return pipe (1303) to flush the bottom of the cement box (1), and allowing the other path of the cement slurry to sequentially pass through a pipeline V, The system comprises a sixth pipeline (906), a first hose (1201), a first spraying pipe (1101), a second hose (1202), a tenth pipeline (910), a third hose (1203), a third spraying pipe (1103), a fourth hose (1204), a seventh pipeline (907) and an eighth pipeline (908), wherein one pipeline enters the cement box (1) through an X valve (1010) and is discharged out of the bottom of the flushed cement box (1) through a second return pipe (1302), and the other pipeline sequentially passes through a ninth pipeline (909) and a XI valve (1011) and is discharged out of the bottom of the flushed cement box (1) through a fourth return pipe (1304), so that continuous circulation is realized, and the first spraying pipe (1101) and the third spraying pipe (1103) are ensured to uniformly and uninterruptedly spray cement slurry to an adjacent side roadbed (8) respectively;
s003. cleaning state
Adding clean water into the cement box (1), opening all valves, circulating the clean water in all pipelines, spraying the clean water through the first spraying pipe (1101), the second spraying pipe (1102) and the third spraying pipe (1103), flushing the cement box (1) and the pipelines, and circulating for multiple times until the cleaning is finished.
