In order to ensure the smooth progress of construction, it is necessary to replace the mixing pipe and grouting head. Frequent replacement of the mixing pipe and grouting head not only increases construction costs, but also reduces construction efficiency. Utility Model Content

[0026] Example 1

[0027] See Figure 1-2 This utility model provides a displacement pumping anchoring agent construction device with cleaning and sealing function, including a dual-liquid grouting pump 1 and a cleaning agent pump 2. The two outlet ends of the dual-liquid grouting pump 1 are respectively connected to a mixing valve 4 through a high-pressure pipe 3. The outlet section of the cleaning agent pump 2 is connected to a check valve 13 through a pipeline. The outlet end of the check valve 13 is connected to a distributor 14. The outlet end of the distributor 14 is connected to the mixing valve 4 through a high-pressure pipe 3.

[0028] The outlet end of the mixing valve 4 is connected to the discharge pipe 5, the discharge pipe 5 is equipped with a mixing pipe 6, and the outlet end of the mixing pipe 6 is equipped with a grouting head 7.

[0029] The mixing valve 4 includes a flat block-shaped valve seat 8, a mixing chamber 10 and four fluid channels 9 communicating with the mixing chamber 10, and a discharge channel 11 in the middle of the mixing chamber 10, which is connected to the discharge pipe 5.

[0030] The two fluid channels 9 located in the middle are grouting channels. Each grouting channel is equipped with a one-way valve 12 at its inlet end. The inlet end of the one-way valve 12 is connected to the high-pressure pipe 3 of the dual-liquid grouting pump 1.

[0031] The two fluid channels 9 located at both ends are cleaning channels, and the cleaning channels are connected to the high-pressure pipe 3 of the distributor 14.

[0032] The distributor 14 includes a main body, which has an inlet and two outlets disposed opposite to each other, and an inner cavity that communicates with the inlet and the outlet respectively.

[0033] The inlet of distributor 14 is connected to the outlet of check valve 13, and the two outlets are connected to mixing valve 4 through high-pressure pipe 3 respectively.

[0034] When using this device, first start the cleaning agent pump to fill the fluid channel, then start the dual-liquid grouting pump 1 to deliver the anchoring agent from its two outlets through the high-pressure pipe 3 to the mixing valve 4. Under the action of the one-way valve 12, the two grouting channels of the mixing valve 4 ensure that the grout enters the mixing chamber 10 smoothly. After being fully mixed in the mixing chamber 10, the mixture enters the discharge pipe 5 through the discharge channel 11. After further mixing in the mixing pipe 6, it is sprayed out from the grouting head 7.

[0035] After the anchoring agent application is completed, the pipeline can be cleaned and replaced by the cleaning agent pump 2 to prevent residual anchoring agent from clogging the pipeline. By starting the cleaning agent pump 2, the cleaning agent enters the distributor 14 through the check valve 13. The distributor 14 delivers the cleaning agent to the cleaning channel of the mixing valve 4 through the high-pressure pipe 3. At this time, the cleaning agent flows in the pipeline to clean and replace the pipeline, ensuring that there is no residual anchoring agent in the pipeline. This can ensure the extended service life of each component of the device, save the consumption of anchoring agent and mixing pipe, reduce the labor intensity of workers, and reduce construction costs.
