Abstract

The invention relates to a drainage pipeline inner wall mortar coating machine and a use method thereof. The drainage pipeline inner wall mortar coating machine comprises a mortar delivery power assembly, a walking power assembly, a mortar jet power assembly and a mortar screeding power assembly; the mortar delivery power assembly comprises a mortar delivery rod, a first driving part used for driving the mortar delivery rod to rotate and a mortar storage cylinder assembly; the walking power assembly comprises a front rack, a back rack, a front wheel set, a back wheel set and a second driving part used for driving the front wheel set and the back wheel set to walk; the mortar jet power assembly comprises a mortar jet power source assembly used for pressurizing mortar in the mortar storage cylinder assembly and transporting the mortar to the mortar screeding power assembly; and the mortar screeding power assembly comprises a plurality of troweling rods, troweling pieces arranged at two ends of the troweling rods and a mortar screeding driving assembly. The drainage pipeline inner wall mortar coating machine and the use method thereof have the advantages that the structure is designedreasonably, the operation and use are convenient, the spraying effect is good, the working efficiency is high, the material drawing is convenient, economic and reasonable, the automation and intelligence degree is high, and the drainage pipeline inner wall mortar coating machine is further operated and used in small underground space.

Description

technical field [0001] The invention relates to the technical field of operation and maintenance of underground drainage pipes, in particular to a mortar spraying machine for the inner wall of a drainage pipe and a use method thereof. Background technique [0002] At present, most of the underground drainage pipes use concrete pipes or metal steel pipes, but as the service life of many operational drainage pipes increases, the pipes themselves are prone to corrosion or even damage. Therefore, it is necessary to carry out anti-corrosion reinforcement for such pipelines. [0003] Since most of the drainage pipes are located under the main traffic roads in the city, it is impossible to carry out large-scale excavation and repair. The existing trenchless repair technology mainly has the following problems: the appearance repair is mainly used, and the problem of internal damage of the pipeline structure cannot be solved; the repair process is complicated, the requirements for t...

Problems solved by technology

[0003] Since most of the drainage pipes are located under the main traffic roads in the city, it is impossible to carry out large-scale excavation and repair

The existing non-excavation repair technology mainly has the following problems: the appearance repair is mainly used, and the problem of internal damage of the pipeline structure cannot be solved; the repair process is complicated, the requirements for the working environment are high, and the operability is poor; the durability after repair is poor, etc.
