Method for reinforcing and lifting rail foundation in workshop
The invention discloses a method for reinforcing and lifting a track foundation in a plant workshop, which comprises the following steps of: arranging a lifting layer and a reinforcing layer below a track foundation, arranging grouting hole positions, lifting holes and grouting holes, and accurately arranging each monitoring point position. According to the method, through shallow layer grouting lifting, grouting is conducted in a small range, grout is solidified, lifting force is generated, and the track foundation is accurately and rapidly lifted; after the lifting of the track foundation is completed, grouting reinforcement is continuously performed on the soft foundation below the foundation, so that the bearing capacity and the deformation resistance of the foundation are enhanced, and the secondary settlement of the track foundation is avoided. The grouting hole positions are arranged in a row shape, and inclined punching and grouting are performed, so that the grouting pipe goes deep into the middle position of the bottom of the track foundation, grout can be utilized more effectively, and the purpose of accurate lifting is achieved; by arranging monitoring points, the displacement of the track and the terrace can be monitored at any time; displacement of a track monitoring point can be used as a standard for completing track lifting.
本发明公开了一种厂房车间内部轨道地基加固抬升的方法，其通过在轨道基础下方设置有抬升层和加固层，并布设注浆孔位、抬升孔和注浆孔，且对各监测点位进行精准布设。本发明通过浅层注浆抬升，使得注浆在小范围进行，浆液凝固并产生抬升力，使得轨道基础精准快速抬升；本发明在轨道基础抬升完成后，继续对基础下面的软弱地基注浆加固，增强了地基的承载力和抗变形能力，避免了轨道基础的二次沉降。通过排状布置注浆孔位，并斜打孔注浆，使得注浆管深入到轨道基础的底部中间位置，这样能更有效地利用浆液，达到精准抬升的目的；通过布置监测点，能随时监测轨道和地坪的位移；轨道监测点的位移可作为轨道抬升完成的标准。
