Description
技术领域technical field

背景技术Background technique
在地质、水文地质及岩矿勘探的钻探领域，特别是小口径绳索取芯钻进工程中，经常会出现涌水或漏水现象，由于钻具与孔壁或双壁钻具之间的间隙极小(毫米量级)，采用加重泥浆容易结垢或堵塞，严重时甚至造成卡钻。如果采用泥浆或水泥进行封堵，由于水泥凝固时间的可控精准度较差，水泥浆很容易被水流稀释冲走，再者由于水泥块具有硬、脆的特性，在后期的钻进中水泥块往往又被钻具扰动破坏，继而再次出现涌水或漏水，给钻探施工和封堵施工造成更大的困难。In the drilling fields of geology, hydrogeology, and rock and mineral exploration, especially in small-diameter wireline core drilling projects, water gushing or water leakage often occurs, because the gap between the drilling tool and the hole wall or double-wall drilling tool is extremely small (millimeter level), the use of aggravated mud is easy to scale or block, and even cause pipe sticking in severe cases. If mud or cement is used for plugging, due to the poor controllable accuracy of the cement setting time, the cement slurry is easily diluted and washed away by the water flow. Moreover, due to the hard and brittle characteristics of the cement block, the cement block in the later drilling will Blocks are often damaged by the disturbance of drilling tools, and then water gushing or water leakage occurs again, which causes greater difficulties for drilling construction and plugging construction.

S2，第一高压注浆管1、第二高压注浆管2穿过孔口密封盖板3伸入至井管4，下入井管4的第一高压注浆管1、第二高压注浆管2通过连接支架14与钢丝绳5连接，第一高压注浆管1、第二高压注浆管2底端分别与三通混合器6的入口连接，三通混合器6的出口与单管13连接，钢丝绳5底端与三通混合器6连接；S2, the first high-pressure grouting pipe 1 and the second high-pressure grouting pipe 2 extend into the well pipe 4 through the orifice sealing cover plate 3, and the first high-pressure grouting pipe 1 and the second high-pressure grouting pipe 4 are lowered into the well pipe 4 The pipe 2 is connected to the steel wire rope 5 through the connecting bracket 14, the bottom ends of the first high-pressure grouting pipe 1 and the second high-pressure grouting pipe 2 are respectively connected to the inlet of the three-way mixer 6, and the outlet of the three-way mixer 6 is connected to the single pipe 13 Connect, the bottom end of the wire rope 5 is connected with the three-way mixer 6;
通过钢丝绳5顶端的卷扬机卷筒将钢丝绳5及第一高压注浆管1、第二高压注浆管2、三通混合器6下入至涌水层段7；Lower the steel wire rope 5, the first high-pressure grouting pipe 1, the second high-pressure grouting pipe 2, and the three-way mixer 6 into the water gushing layer section 7 through the hoist drum at the top of the steel wire rope 5;
S3，本胶注浆储罐9、硬化剂注浆储罐10中储存有相互配合的AB胶，本胶浆液和硬化剂浆液通过双液泵8、第一高压注浆管1、第二高压注浆管2输送至三通混合器6中混合，利用双液泵8的压力把混合浆液通过单管13压入涌水层段7的钻孔漏层，注浆压力上升至初始注浆压力的5-10倍后结束注浆；S3, the glue grouting storage tank 9 and the hardener grouting storage tank 10 store mutually matched AB glue. The grouting pipe 2 is transported to the three-way mixer 6 for mixing, and the pressure of the double-liquid pump 8 is used to press the mixed grout through the single pipe 13 into the leaky layer of the borehole of the water gushing section 7, and the grouting pressure rises to 100% of the initial grouting pressure. Finish grouting after 5-10 times;
S4，待10-20分钟混合浆液凝固后，打开孔口密封盖板3，拔出设备结束作业。S4, after the mixed slurry is solidified for 10-20 minutes, open the orifice sealing cover plate 3, and pull out the equipment to end the operation.
