At present, vertical drainage passage plastic draining board in pre-pressing and reinforcing soft earth foundation instead of conventional sand wick substantially, generally plastic draining board plate bottom in soft plasticviscosity soil, silt clay and without the sand of artesian water in set construction smoothly, without substantially rewinding phenomenon, but to rewind phenomenon in setting construction extremely serious for plastic draining board when plastic draining board plate bottom is in floating silt, plastic flow mud, plastic flow mud matter clay and in having the sand of artesian water, even cannot complete to set construction, have a strong impact on construction quality and the progress of plastic draining board.
Summary of the invention
It is an object of the invention to design a kind of steel plate shoe and eliminate during plastic draining board sets the method rewinding phenomenon, plastic draining board can be met and set prescription, what improve again plastic draining board sets efficiency, and the cost of this steel plate shoe is only the 50% ~ 80% of a linear meter(lin.m.) plastic draining board fee of material.
A kind of steel plate shoe of the present invention eliminates during plastic draining board sets the method rewinding phenomenon, includes S1 and S2, totally two steps；
Described step S1 is for making steel plate shoe；
Described step S2 be plastic draining board set enforcement.
Described step S1 comprises again 101 to 103 totally 3 steps:
Step 101: cut sheet metal 1, and the sheet metal length cut is 140mm ~ 200mm, wide for 60mm ~ 100mm, thickness is 0.2mm ~ 0.8mm, described sheet metal 1, and its material can be ferrum, steel etc., such as sheet iron, thin steel roll etc.；
Step 102: 1 circular hole 2 of each brill in distance minor face 25mm place on the width center line of sheet metal 1, Circularhole diameter is 2mm ~ 5mm, and described Circularhole diameter is slightly larger than the diameter of iron wire 3；Iron wire 3 is converted into "U" shaped traverse two circular holes 2 of steel-sheet, and bind together stubborn at the back side of sheet metal 1 for the two ends of iron wire 3, the gap reserving 8mm ~ 10mm when pricking between sheet metal front " u "-shaped iron wire 3 and sheet metal 1 twisted by iron wire 3, the material of described iron wire 3 or be ferrum or steel, also can be the rope of same intensity, diameter can be 2mm ~ 5mm, and iron wire length is 120mm ~ 300mm；
Step 103: or " u "-shaped iron wire 3 is welded on the position (not be used on sheet metal during welding and bore circular hole) of above-mentioned circular hole 2, when iron wire 3 welds, the gap of reserved 8mm ~ 10mm between " u "-shaped iron wire 3 and sheet metal 1 on sheet metal face, the material of described iron wire 3 or be ferrum or steel, diameter can be 2mm ~ 5mm, and iron wire length is 120mm ~ 300mm.
Described step S2 includes again 201 to 203 totally 3 steps:
Step 201: by plastic draining board 4 from board-plugging device intubate 5 bottom pull-out, through " u "-shaped iron wire 3 and turn back, the length 150mm that turns back ~ 250mm；
Step 202: the operator of feed strain the other end of plastic draining board 4, the plastic draining board 4 turned back is inserted into along pulling force plug and intubates in 5 by the operator of upper shoe, makes sheet metal shoe and the bottom intubating 5 is close to；
Step 203: the machinery operator of board-plugging device will intubate 5 and be placed in a site insertion soil body, the operator of feed are along intubating 5 deepen continuously and loose one's grip and make plastic draining board 4 to enter the soil body together with intubating 5 gradually, intubate sheet metal shoe when pulling out 5 times and stay in the soil body, it is ensured that the wrench of plastic draining board 4 is not extracted with intubating 5.
A kind of steel plate shoe of the present invention eliminates during plastic draining board sets the advantage of the method rewinding phenomenon: when plastic draining board is inserted to relatively Soft Soil Layer, steel plate hard-pressed bale intubates bottom, not easily occurs into mud plugging phenomenon；When being inserted to harder sandy soils, there is steel plate protection draining board, disconnected plate phenomenon not easily occurs, not only increases the effect plugging plastic draining board, also ensure that the construction quality of plastic draining board simultaneously.Verifying through several engineering practice, this shoe can be prevented effectively to be occurred rewinding phenomenon when setting plastic draining board, meets engineering design and code requirement.
