Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1, in this utility model embodiment, a kind of caisson cutting edge installs structure, at least includes ground 1, cutting shoe 2, template 3, poppet 4, sleeper 5 and sand bedding course 6；Described ground 1 is arranged on the whole structure lowermost end that installs, and is provided with sand bedding course 6 above it；Described sleeper 5 is laid on sand bedding course 6 upper end；Described template 3 bottom is connected with sleeper 5；Described cutting shoe 2 is arranged in template 3；Described poppet 4 is inclined structure, and its bottom contacts with sleeper 5, and top contacts with template 3.
As further technical scheme of the present utility model: described poppet 4 is whole poppet or half poppet structure.
This utility model is in use: adopts and should calculate one-time-concreting height during pad frame method construction so that it is less than the bearing capacity of ground.Diameter or the length of side light open caisson within 8m, when soil property is better, can adopt brick base.Brick cutting shoe base builds the cutting shoe tread width that should ensure that cutting shoe designing requirement by laying bricks or stones, and brick cutting shoe intensity and bottom width should be able to be resisted the horizontal thrust effect of cutting shoe slope concrete and be remained stable for: stock mould inwall application 1: 3 cement mortar is floating.The small-sized open caisson of lighter in weight, can adopt when soil property is good sand bedding course, cushion lime or in ground grooving be made clay model, its inwall is floating by 1: 3 cement mortar.
When adopting poppet or half poppet method, need first to lay at cutting shoe place sand bedding course, then spread rim wood and poppet thereon.Chock commonly uses 160 × 220mm sleeper, poppet quantity heavy according to first segment and weight and the allowable bearing of ground (or sand bedding course) calculate and determine, spacing is generally 0.5～1.0m.Poppet is laid should be symmetrical, generally first sets 8 groups of location poppets, and often group is made up of 2～3 poppets, the standing 4 groups of location poppets of rectangular open caisson, its position, long limit two ends 0.15L (L is length of long sides), installs general poppet therebetween, and poppet should vertically be laid by the borehole wall.Circular open caisson is directed at the center of circle along caisson cutting edge circular arc portion and lays, and installs cutting shoe, borehole wall template on chock.Laying chock should make end face be maintained at the same horizontal plane, levelling with level gauge, makes the discrepancy in elevation within 10mm, and tamps with sand between chock, and chock centrage should overlap with cutting shoe centrage；Chock buried depth is the half of its thickness, peripheral hardware gutter in poppet.When foundation bearing capacity is relatively low, it is computed poppet expense more, when laying overstocked, sand cushion strengthening should be divided at chock, with by heavy and weight be diffused into more in large area, with uneven sedimentation in avoiding making, poppet quantity can be reduced simultaneously, make to be prone to levelling. it is easy to chock and lays and extract.
