背景技术Background technique
岩土体加固工程中，通常需要将不良的地基土与固化添加剂进行混合搅拌再填铺，提高原来地基土的承载力和强度，也有很多场合将含有重金属或者有毒物质的淤泥质土与固化剂混合，将污染物封固在土体中，形成稳定的结合体，作为填土使用。因此在原料土与固化剂混合的过程中，如何精确控制固化剂掺量和均匀性成为了施工的关键，常规固化剂通常是粉状的混合物，在机械化拌和施工中，输送管道通常会被堵塞，形成粉质拱结构，使得无法加注固化剂。本发明针对这一问题，提出了一种用于粉体固化剂输运的自重流化床管道系统及其使用方法。流化床原理是指将大量固体颗粒悬浮于运动的流体之中，从而使颗粒具有流体的某些表观特征，主要有散式流化态与聚式流化态两类。当流体通过床层的速度逐渐提高到某值时，颗粒出现松动，颗粒间空隙增大，床层体积出现膨胀。如果再进一步提高流体速度，床层将不能维持固定状态。此时，颗粒全部悬浮于流体中，显示出相当不规则的运动。随着流速的提高，颗粒的运动愈加剧烈，床层的膨胀也随之增大，但是颗粒仍逗留在床层内而不被流体带出，此时只要有开口，则流体会带着颗粒流出，呈现气力运输的状态。本发明正是利用这一原理，在固化剂输运管道中设置3层腔室，制造出流化床的形态，通过空气循环压缩机的泵送，利用粉体自身的重量，由高向低处流淌，将粉质颗粒向前输送。In rock and soil reinforcement projects, it is usually necessary to mix and mix poor foundation soil with curing additives before filling to improve the bearing capacity and strength of the original foundation soil. In many cases, muddy soil containing heavy metals or toxic substances and curing agents Mixing, sealing pollutants in the soil, forming a stable combination, used as fill. Therefore, in the process of mixing raw soil and curing agent, how to accurately control the dosage and uniformity of the curing agent has become the key to construction. Conventional curing agents are usually powdery mixtures. During mechanized mixing construction, the delivery pipes are usually blocked. , forming a silty arch structure, making it impossible to add curing agent. Aiming at this problem, the present invention proposes a self-gravity fluidized bed pipeline system for transporting powder curing agent and its application method. The principle of a fluidized bed refers to suspending a large number of solid particles in a moving fluid, so that the particles have some apparent characteristics of the fluid. There are mainly two types of fluidized state and fluidized state. When the velocity of the fluid passing through the bed gradually increases to a certain value, the particles will loosen, the gaps between the particles will increase, and the volume of the bed will expand. If the fluid velocity is further increased, the bed cannot maintain a stationary state. At this point, the particles are all suspended in the fluid, exhibiting rather irregular motion. As the flow rate increases, the movement of the particles becomes more violent, and the expansion of the bed increases accordingly, but the particles still stay in the bed and are not carried out by the fluid. At this time, as long as there is an opening, the fluid will flow out with the particles , showing the state of pneumatic transport. The present invention utilizes this principle to set up three layers of chambers in the curing agent transportation pipeline to create the form of a fluidized bed. Through the pumping of the air circulation compressor, the weight of the powder itself is used to move from high to low. It flows at the place and transports the silty particles forward.
