Suction-spraying type dense filling device and method for hole and pore

Abstract

The invention discloses a suction-spraying type dense filling device and method for a hole and a pore. An air compressor of the device is connected with an inclined pipe input port of an inclined three-way pipe joint; the output end of a funnel is connected with a straight pipe input port of the inclined three-way pipe joint; and a straight pipe output port of the inclined three-way pipe joint isconnected with an input port of a grouting material conveying pipe through a steel wire hose. According to the suction-spraying type dense filling method for the hole and the pore, grouting materialsare poured into the funnel, the air compressor is started, compressed air is fed into the inclined three-way pipe joint, at the moment, a pipeline between a straight pipe of the inclined three-way pipe joint and the funnel is in negative pressure, and the grouting materials are sucked into the straight pipe of the inclined three-way pipe joint; and positive pressure is formed from the straight pipe of the inclined three-way pipe joint to the grouting material conveying pipe, the grouting materials sucked into the straight pipe of the inclined three-way pipe joint is sprayed out from the grouting material conveying pipe, the grouting material conveying pipe is inserted into the hole and the pore, and the grouting materials sprayed out from the grouting material conveying pipe directly reaches the deep parts of the hole and the pore. According to the suction-spraying type dense filling device and method for the hole and the pore, the purpose of dense filling is achieved, potential safetyhazards caused by the holes and the pores are eradicated, and the overall attractiveness of a building is improved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a suction-spray type dense filling device and method for holes and pores. Background technique [0002] In the construction process of various construction projects, it is inevitable that some holes (gaps) will be left in the engineering entity after the construction is completed. Generally, conventional filling methods can be used to meet the requirements. In special cases, such as small and narrow holes, filling with cement slurry, cement mortar or grouting materials can also meet the requirements, but this method is only suitable for vertical holes or holes inclined, and the filling material can also flow through the falling of its own weight. Fill the holes (gaps) tightly. However, for straight or nearly straight holes (gaps) with a large depth, the self-flowing grouting material cannot be filled and compacted, which may lead to safety hazards in the quality...

Problems solved by technology

However, for straight or nearly straight holes (gaps) with a large depth, the self-flowing grouting material cannot be filled and compacted, which may lead to safety hazards in the quality of construction projects and affect the overall aesthetic performance of the building.
