The invention discloses a radiation type positive and negative pressure combination vacuum preloading foundation treatment system. The vacuum preloading foundation treatment system comprises divergent type plug-in connectors and preloading pits, wherein in each divergent type plug-in connector, one half of drainage board connecting ends are connected with first connecting pipes through first channels, the other half of the drainage board connecting ends are connected with second connecting pipes through second channels, drainage boards adjacently arranged are connected with different channels, and the first connecting pipes and the second connecting pipes are provided with pumping drainage devices and inflation devices. The invention further provides a method adopting the foundation treatment system to carry out vacuum preloading foundation treatment. According to the system and the treatment method, when the pumping drainage effect of the drainage boards is greatly reduced, the drainage boards distributed in a radiation crossed manner can simultaneously carry out inflation and exhausting so as to enhance the pumping drainage effect; water is squeezed near the drainage boards carrying out pumping drainage by inflated air, and the water content of soil is reduced; the radiation distribution structure of the drainage boards is favorable to increasing the radiation area of pumping drainage and inflation; and during inflation, inflation quantity and inflation area can be increased through starting all inflation devices, so that pumping drainage air quantity is larger during pumping drainage, and more water can be brought out.
Description
technical field [0001] The invention relates to a radial positive and negative pressure combined vacuum preloading foundation treatment system. The present invention also relates to a method for vacuum preloading foundation treatment using the above-mentioned radiant positive and negative pressure combined vacuum preloading foundation treatment system. Background technique [0002] In the traditional vacuum preloading treatment method, the drainage board can only extract the water in a limited range around it, and the water drainage effect for the farther and deeper water is not good, which greatly affects the effect of soil treatment. Contents of the invention [0003] In view of the deficiencies in the background technology, the technical problem to be solved by the present invention is to provide a radiation type positive and negative pressure combined vacuum preloading ground treatment system that can improve pumping efficiency. The present invention also provides a m...
