Sand layer grouting device and grouting method
A sand layer grouting device relates to the field of sand layer grouting and comprises a grouting frame body, the grouting frame body comprises a grouting bottom plate, a fixed wide plate, a fixed side plate, a movable wide plate and an extrusion grouting column, the fixed wide plate is provided with a sleeve moving column, the movable wide plate is provided with sleeve column holes penetrating through the two sides of the movable wide plate, and the movable wide plate is provided with an extrusion grouting column. A grout inlet hole penetrating through the wall face of the extrusion grouting column is formed in the connecting position of the extrusion grouting column and the width fixing plate, liquid spraying holes are further formed in the extrusion grouting column, the grouting device can improve the uniformity of grout distribution during sand layer grouting, the coverage area of grouting grout is enlarged, and the stability effect of overall sand layer grouting is improved; the grouting method adopting the grouting device comprises the steps that firstly, the grouting frame body is inserted into a sand layer; secondly, grout is injected between the fixed wide plate and the movable wide plate; thirdly, the movable wide plate is moved towards the fixed wide plate, so that the extrusion grouting column is exposed out of the sprayed grout; and fourthly, the grout continues to be injected into the sand layer, and grouting of the sand layer is completed after the grout is solidified.
一种砂层注浆装置，涉及砂层注浆领域，包括注浆框体，所述注浆框体包括注浆底板、固宽板、固侧板、动宽板和挤压注浆柱，所述固宽板上有套移柱，所述动宽板上有贯穿所述动宽板两侧的套柱孔，所述挤压注浆柱与所述固宽板连接处有贯穿所述挤压注浆柱壁面的入浆孔，在所述挤压注浆柱上还有喷液孔，本注浆装置可以提高砂层注浆时浆液分布的均匀性，扩大注浆浆液的覆盖面积，提升整体砂层注浆的稳固效果；采用上述注浆装置的注浆方法，包括步骤一，将注浆框体插入砂层中；步骤二，向固宽板和动宽板间注入浆液；步骤三，将动宽板向固宽板移动，使得挤压注浆柱露出喷出浆液；步骤四，继续向其中注入浆液，等浆液凝固，完成砂层注浆。
