The invention discloses a multiple high-pressure grouting jetting device for building construction, which comprises a grouting column head, a variable-diameter nozzle assembly, a variable-direction grouting assembly and a jet pump box fixedly mounted on one side of the variable-direction grouting assembly, and the variable-diameter nozzle assembly is fixedly mounted at the end part of the jet pump box; the two sets of direction-changing grouting assemblies and the two sets of jet pump boxes are symmetrically arranged on the two sides of the direction-changing grouting assemblies with respect to the original point of the circle center axis of the slurry jetting column head. Each direction-changing grouting assembly comprises a fixed guide base, a rotating ring base and a driving mandrel. According to the high-pressure jet flow device, the variable-phase jet flow assembly is arranged, rotary ring seats capable of swinging on the two sides of a fixed guide seat are used for driving the variable-diameter nozzle assembly and the jet flow pump box to conduct deflection motion under the control of a driving mandrel, high-pressure jet flow rushes and breaks through a soil layer structure, and therefore a jet flow type diffusion space is formed in a soil body, and the space is in a center scattering shape; and the slurry is solidified in the scattering space, so that the bonding effect of the surrounding body and the soil layer is improved, and the surrounding body is prevented from settling.
本发明公开了一种建筑施工用多重高压注浆喷射装置，包括：射浆柱头、变径喷口组件、变向注浆组件以及固定安装于变向注浆组件一侧的射流泵盒，变径喷口组件固定安装于射流泵盒的端部，变向注浆组件和射流泵盒的数量为两组且关于射浆柱头的圆心轴线原点对称布置于变向注浆组件的两侧，变向注浆组件包括定导座、转环座和驱动芯轴。本发明中，通过设置变相射流组件，利用定导座两侧可摆动的转环座在驱动芯轴的控制下带动变径喷口组件和射流泵盒进行偏转运动，以高压射流冲时和击穿土层结构从而在土体内形成射流式的扩散空间，空间呈中心散射状，浆液在该散射状空间内固化，提高周结体与土层的接合效果，进而防止周结体沉降。
