Oblique spraying type high-pressure spraying system and construction method
The invention relates to an inclined spraying type high-pressure injection system and a construction method, and the inclined spraying type high-pressure injection system comprises a high-pressure gas supply unit, a material supply unit, a high-pressure injection system unit, a gas material conveying unit and a construction drilling machine unit. High-pressure gas and curing agent powder are mixed and compressed in the mixer to form rotational flow, the pneumatic conveying capacity is enhanced, the pressure loss of the pipeline is reduced, and the mixer composed of the shrinkage pipe, the mixing pipe and the diffusion pipe utilizes diameter shrinkage-equal diameter-diameter expansion space structure change and geometric dimension optimization design. The dynamic pressure of the gas-solid two-phase fluid in the pipeline can be increased by utilizing the generation of the gas-solid two-phase rotational flow in the mixer; according to the invention, the blockage of the curing agent powder in the pneumatic conveying pipeline can be effectively prevented, the spraying force of the underground gas material spraying beam is improved, the spraying diameter of the dry spraying mixing pile is increased, the construction quality is controllable and reliable, and the market competitiveness is strong.
本发明涉及一种斜喷式高压喷射系统及施工方法，包括高压供气、供料、高压喷射系统、气料输送及施工钻机五个单元，斜喷式高压喷射系统集中高压气体的喷射能量通过直接喷射冲击和引射引流作用，把高压气体与固化剂粉料在混合器中混合压缩形成旋流，增强了气力输送能力，降低了管道压力损失，收缩管、混合管和扩散管构成的混合器利用缩径—等径—扩径的空间结构变化及几何尺寸优化设计，可利用混合器中气固两相旋流的生成提升管道内气固两相流体的动压力；本发明可有效防止气力输送管道中的固化剂粉料堵塞，提高地下气料喷射束的喷射力，增大干喷搅拌桩的喷射直径，且施工质量可控可靠，市场竞争力强。
