Concrete pumping pipeline cleaning method and device

Abstract

The invention relates to the field of concrete pipeline transportation, in particular to a concrete pumping pipeline cleaning method and device. The method comprises the following steps that after concrete putting is finished, a mixture of ice blocks and ice sand is continuously put into a hopper, and the mixture is pressed to ensure that the mixture can be sucked by a pumping machine after concrete pumping is finished; the ice blocks and water are continuously added into the hopper of the pumping machine, and the size of the ice blocks does not exceed the volume of a 1000-mm pumping pipeline; the sufficient amount of water is continuously added into the hopper of the pumping machine to push the ice blocks and concrete to move forwards until all the concrete in the pumping pipeline is pushed out; the pumping machine is stopped, and the water in the pumping pipeline is kept to be not drained until next-time concrete pumping. By adopting the concrete pumping pipeline cleaning method, the use cost is low, the pipeline does not need to be disassembled, and blocking cannot occur.

Description

technical field [0001] The invention relates to the field of concrete pipeline transportation, in particular to a method and device for cleaning concrete pumping pipelines. Background technique [0002] Concrete is a commonly used building material. After being produced in the mixing station, it is sent to the place of use by transportation equipment, and then pressed into the pumping pipeline by a pumping machine, and then transported to the construction site through the pumping pipeline. After the concrete is delivered , It is usually necessary to clean up the residual concrete in the pumping pipeline, so as not to block the pipeline after the concrete solidifies. [0003] There are two traditional cleaning methods, one is to directly pump water through the pump to wash the concrete in the pumping pipe, wash away the cement in it, and then disassemble the bottom of the pumping machine to remove the reserved water from the pumping pipe.

Problems solved by technology

[0003] There are two traditional cleaning methods, one is to directly pump water through the pump to wash the concrete in the pumping pipe, wash away the cement in it, and then disassemble the bottom of the pumping machine to remove the reserved water from the pumping pipe. Sand and gravel and other aggregates are discharged. This method is generally only suitable for the construction of low floors, because when the floors are high, there will be more concrete left in the pumping pipe. On the one hand, direct flushing will cause a lot of waste, and more importantly, A lot of stones and sand will be produced after direct flushing, especially in high-rise construction where there are many elbows in the pumping pipeline, which can easily cause blockage of the pumping pipeline. Once blocked, it can only be removed in sections, cleaned and reinstalled. The workload is very heavy, so water flushing generally cannot be used to clean the high-rise pumping pipeline; another cleaning method is to use the air compressor to push the cleaning ball to clean the pipeline. The specific method is: after the concrete is pumped, first remove the bottom A section of concrete delivery pump pipe, quickly put a sponge ball or cloth ball, and then connect the pumping pipe to the air compressor, the air compressor pushes the cleaning ball to discharge all the concrete out of the pumping pipe

The advantage of this cleaning method is that it can better avoid the waste of concrete, but there are still many disadvantages, specifically at least including the following points: 1. It needs to be equipped with a separate air compressor, and the use cost is very high; 2. 1. When the pumping pipeline is removed, a lot of concrete will flow out, which is not only wasteful but also pollutes the construction environment; 3. Sponge balls or cloth balls are particularly easy to block in the pumping pipeline, especially at the pipe joints or turning positions. It takes a lot of manpower and material resources to check the clogged position, and then remove the pipe to clean it. During the cleaning process, concrete waste and pollution will occur, and then the pipe can be reconnected, which is quite troublesome.

[0004] In general, there is still a lack of a construction method and special device for cleaning concrete pumping pipelines with low investment and good effect
