s6: after pouring the wall of a well, through slip casting pipe pump sending air conditioning on towards the wall of a well, supplementary cement solidifies, because the firm degree of the wall of a well is different, the content of the cement of pouring and stone is different, consequently needs the air conditioning of different content to assist to solidify it, avoids air conditioning too much to lead to solidifying too fast and chap, avoids air conditioning too little to lead to unable solidification, influences follow-up exploitation work.
7. The automated dual fluid grouting pump based on flow control of claim 6, wherein: the step S5 further includes:
a1: grading the diameter of the collected stone blocks, wherein the diameter is 3-6CM for the first grade, the diameter is 6-10CM for the second grade, and the diameter is 10CM-15CM for the third grade;
a2: grading the descending distances of the well, wherein the descending distance of the well is 0.5-1M in the same time period as the first grade, the descending distance of the well is 1-1.5M in the second grade, the descending distance of the well is 1.5-2M in the third grade, the descending distances of the different grades correspond to the firmness degrees of the well walls of the different grades, and the first grade is the hardest and the third grade is the loosest;
a3: for different levels of firmness, the content of the filled cement is calculated as follows:
in the formula, P is the required cement filling content for the current grade, M is the total weight of the stone blocks of the current grade, dmaxThe maximum stone diameter of the current grade, X the current firm grade, L the drill bit descending distance, D the drill bit diameter, DminThe minimum stone diameter for the current grade can be obtained by the formula, the required cement filling content is inversely proportional to the descending distance of the drill bit aiming at the current grade, if the descending distance of the drill bit is larger, the cement is required to be less, the larger the descending of the drill bit is, the looser the current well wall is proved, the vacancy generated after the drill bit is mined is larger, the required cement is less, and the cement is solidifiedThe solidified hard degree is difficult to support a larger vacancy, and in a limited space, more stones and cement are required to be mixed into concrete for the larger vacancy so as to keep the firmness of the vacancy;
a4: in step a3, the required stone weight for the current grade is calculated as follows:
in the formula, G is the weight of the stones required by the current grade, M is the total weight of the stones of the current grade, P is specific to the current grade, the formula can obtain the weight of the stones required by the current grade is in inverse proportion to the required cement content, namely, the more the cement is, the less the vacancy of the current well wall is, if more stones are filled, the cement is difficult to permeate into the well wall in the subsequent solidification process, so that the inner diameter of the well wall is reduced after solidification, and the subsequent exploitation is influenced.
8. The automated dual fluid grouting pump based on flow control of claim 7, wherein: in the step S6, the cool air discharge rate required for the current level is calculated as follows:
in the formula, W is the cold air content required by the current grade, rho1Is the outside humidity, ρ2For the inside humidity of drilling, L is drill bit descending distance, G is the required stone weight of current level, M is the total weight of the stone of current level, B is the slip casting pipe diameter, S is the time of interval control, can obtain by this formula, the required air conditioning content of current level is the inverse ratio with required stone weight, the stone weight is big more, cement content is less, the content that its solidification is assisted to required air conditioning is less, avoid can't lead to appearing cooling excessively to the air conditioning content, the wall of a well is cracked, the phenomenon that the wall of a well peeled off in the follow-up exploitation process appears.
