Ground grouting reinforcement construction process
The invention discloses a ground grouting reinforcement construction process, and relates to the technical field of geotechnical engineering. A to-be-reinforced base can be reinforced, so that the to-be-reinforced base has enough strength for bearing tunnel construction. The ground grouting reinforcement construction process comprises the steps that S1, a hole position is determined; S2, drilling is conducted according to the hole position; S3, a grouting outer pipe is placed into a drilled hole; S4, a sleeve shell material is injected between the drilled hole and the grouting outer pipe; S5, a grouting inner pipe is placed into the grouting outer pipe, and grouting is conducted by aligning one grout outlet part of the grouting inner pipe; and S6, the grouting inner pipe is moved, and grouting is conducted by sequentially aligning all the grout outlet parts. According to the ground grouting reinforcement construction process, through cooperation of the grouting inner pipe and the grouting outer pipe, grout is injected into gaps of a stratum and diffused out of a certain range under the action of pressure, so that the stratum within the range is firmly cemented, the self-stabilizing capacity of the stratum within the peripheral range of the drilled hole is improved, and then the single hole position is reinforced and has enough strength for bearing tunnel construction.
本发明公开了一种地面注浆加固施工工艺，涉及岩土工程技术领域，能够对待加固基底进行加固，使其具有足够承担隧道施工的强度。包括步骤S1、确定孔位；S2、根据孔位进行钻孔；S3、向钻孔中放入注浆外管；S4、向钻孔与注浆外管之间注入套壳料；S5、向注浆外管中放入注浆内管，对齐其一出浆部进行注浆；S6、移动注浆内管，依次对齐所有出浆部进行注浆。本发明通过注浆内管和注浆外管的配合，将浆液注入到地层的间隙中并受压力作用扩散出一定范围，以此对该范围内的地层进行牢固胶结，由此提高钻孔周边范围内的地层自稳能力，进而对单个孔位进行加固，使其具有足够承担隧道施工的强度。
