Abstract

The invention discloses a construction method for the grouting amount of cement paste, which comprises the following steps of: sampling the cement paste after the cement paste is stirred, and filling a paste storage barrel with the sampled cement paste; then measuring the sample by using a slurry meter, accurately measuring the specific gravity of the sample, and verifying whether the cement slurry reaches the mix proportion required by the design or not; and connecting an intelligent digital cement slurry flow meter between a slurry outlet of an existing grouting machine and a grouting pipe for metering the outflow quantity of cement slurry. The invention relates to the technical field of cement paste grouting. According to the construction method for the grouting amount of the cement paste, the specific gravity of the cement paste is measured through on-site sampling, whether the cement paste meets the design requirement or not is further verified, and the defect that the mixing proportion is not accurate is overcome. The grouting amount of an original grouting machine is roughly controlled, the accurate metering effect is achieved, and potential quality hazards caused by insufficient grouting amount to the cast-in-place pile can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of cement grouting, in particular to a construction method for the amount of cement grouting. Background technique [0002] Cement grouting foundation refers to a kind of grouting foundation. The cement slurry is evenly injected into the soil through the grouting pump and the grouting pipe, and is driven out of the cracks in the rock or between the soil particles by means of filling, infiltration and compaction. moisture and gas, and fill its position. After it hardens, the rock and soil will be cemented into a whole to form a new rock and soil mass with high strength, low compressibility, high impermeability and good stability, so that the foundation can be obtained Reinforcement to prevent or reduce penetration and uneven settlement. The advantages of this kind of foundation are that it is easy to obtain materials, easy to operate, and cheap. It is suitable for the reinforcement of soft clay, silt, cohesi...
