Abstract
The present invention relates to an auxiliary construction process for treating foundation soil with high water content by utilizing dynamic consolidation method. It is characterized by that in the high water-content foundation soil interior firstly the quicklime or other water-absorbing material can be used, and made into the uniformly-distributed lime-soil piles or lime-soil piers, then the dynamic consolidation process can be made.
Description
Affiliated technical field
The present invention relates to a kind of processing method, especially to high-moisture silty clay Measures for Making Ground and Foundation method to building lot.
Background technology
The processing method of building lot, according to different building requirements and ground soil property characteristics many kinds are arranged, strong ram be a kind of weight hold high ram method for processing foundation, by improving the soil compactness, reducing compressibility of Soil, increase substantially foundation capability, because cost is low, speed is fast, is called as the method for processing foundation of getting twice the result with half the effort.Yet on many foundation soil water content soil with high, dynamic compaction but is restricted, and reason is often to cause foundation soil to become " spongy soil " after strong the rammer, has to adopt the higher piling method of cost.
Summary of the invention
The present invention is exactly the auxiliary construction process at a kind of strong rammer treatment high-water content foundation soil of the shortcoming design of prior art, after adopting this technology, can use the Treatment by Dynamic Compaction ground on the ground of high-moisture, technology is easy to be reliable, reduce cost, accelerate the duration.
The technical solution adopted for the present invention to solve the technical problems is: the auxiliary construction process that designs a kind of strong rammer treatment high-water content foundation soil: make equally distributed ash stake or grey pier with quicklime or other absorbent material earlier in the high-moisture foundation soil, and then ram by force.With the ash stake that quicklime is made, be that to make a call to a diameter earlier in the high-moisture foundation soil be 180～400 millimeters, the degree of depth is 1～5 meter stake hole, tamps quicklime then in the stake hole, the interval in a hole be generally 0.7～1.5 meter uniform.And with the grey pier that quicklime is made, then be that to make a call to a diameter earlier in the high-moisture foundation soil be 0.5～1 meter, the degree of depth is generally 1～2 meter pier hole, tamps quicklime then in the pier hole, the interval in pier hole be generally 2～3 meters uniform.
The invention has the beneficial effects as follows,, expanded the accommodation of strong rammer Ground Treatment because the strong absorptive of quicklime when treated high-moisture ground rams by force again, the situation that foundation soil becomes " spongy soil " can not occur again.
The specific embodiment
One. near on the saturated silty clay foundation soil, 300 millimeters of diameters are suppressed at 1 meter at every interval earlier in water content, and quicklime is tamped in dark 3 meters stake hole then in the stake hole, ram by force again.Characteristic value of foundation bearing capacity after the processing is 180KPa.
Two. having on the saturated silty clay foundation soil of five meters saturated yielding soil layers, 2 meters at every interval, earlier ramming out the degree of depth with the hammer ram of 0.6 meter of diameter is 1 meter Dun Keng, tamps quicklime then in pier is cheated, and rams by force again.Characteristic value of foundation bearing capacity after the processing is 200KPa.
Claims (3)
