Problems solved by technology

The current transportation method is mostly manual transportation. Due to the high temperature of the hot furnace roof and the grouting of the protective plate, the physical energy consumption of the workers is large, the labor intensity is high, and the work efficiency is low, which restricts the entire construction progress.

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] See attached figure 1 , The coke oven thermal pumping grouting construction method disclosed in the present invention is constructed according to the following steps.

[0021] a. The intermediate platform 1 and the end platform 9 are respectively arranged on both sides of the coke oven, the mud mixer 2 is arranged on the intermediate platform 1 on one side of the coke oven, and a mud storage box 3 is arranged in front of the mud mixer 2. The mud storage box is generally A rectangle whose size is made on-site according to usage. A vertical mud pump 4 is housed in the mud storage box 3, and the present embodiment adopts a PNL vertical mud pump.

[0022] b. Set up a support frame with a height of 500-600mm on the coke oven roof 8, the scaffolding on the construction site is enough, fix the main mud pipeline 5 on the support frame, and fix the main...

Abstract

The invention provides a coke oven heat-state pumping grouting construction method. The coke oven heat-state pumping grouting construction method comprises the following construction steps: arranging a slurry mixer on a middle platform or an end platform, arranging a slurry storage box in the front of the slurry mixer, and arranging a vertical slurry pump in the storage box; putting up a support frame with the height of 500 to 600 mm on the top of a furnace, and fixing a main slurry pipeline on the support frame, wherein one end of the main slurry pipeline is connected with the vertical slurry pump; arranging grouting branch pipes at the two sides of the main slurry pipeline at intervals, and arranging stop valves between the grouting branch pipes and the main slurry pipeline; and in the whole grouting process, injecting slurry into each grouting branch pipe all the time, and controlling the stop valve on each grouting branch pipe so as to realize the control on grouting points; and after the periodical grouting is finished, pumping clean water by the vertical slurry pump so as to clean the pipeline. The coke oven heat-state pumping grouting construction method has the advantages that a conventional manual conveying manner is replaced by a manner of conveying the slurry by the pipelines, so that the labor intensity of workers is greatly alleviated, the setting rate of slurry is reduced, the working efficiency is improved, the construction cost is reduced, and the construction period is shortened.

Description

technical field [0001] The invention relates to a coke oven grouting construction method, in particular to a coke oven thermal pumping grouting construction method. Background technique [0002] During coke oven construction, hot grouting for furnace roof and protection plate accounts for 70% of hot construction. The construction of the coke oven in a hot state indicates that the coke oven is about to be put into production. The grouting of the furnace roof and the protective plate is the work that must be completed before the coke oven is put into production. The coke oven emits a lot of heat and the mud solidifies faster. The process is more difficult. The current transportation method is mostly manual transportation. Due to the high temperature of the hot furnace roof and the grouting of the protective plate, the physical energy consumption of the workers is large, the labor intensity is high, and the work efficiency is low, which restricts the entire construction progre...
