Description
Technical field
The utility model relates to technical field of building construction, refers to that structure strengthened by a kind of deep foundation ater-casting bottom especially.
Background technology
For the differential settlement in solution engineering loading procedure and distortion, general needs arranges ater-casting between two annexes.
Traditional ater-casting, ultra-deep high water level basis adopts traditional method to be the steel fabric sheet colligation of both sides, basic ater-casting, after Base isolation system concreting being caused like this, by concrete spillage not easy to clean, high hydraulic pressure due to underground water causes the problem of ater-casting seepage, and the hidden danger of quality such as cause that post empiricism quality not easily ensures thus, the construction at position, ater-casting, basis brings and such as affects programming, and construction quality is difficult to ensure.
Utility model content
The purpose of this utility model is to provide a kind of deep foundation ater-casting bottom and strengthens structure, and this structure can solve the problem, and effectively stops the high hydraulic pressure of underground water, avoids the generation of ater-casting Seepage.
To achieve these goals, the utility model have employed following technical scheme: a kind of deep foundation post empiricism structure, comprises the concrete bed course in spill, is provided with enhancement Layer, base plate based on above described enhancement Layer in the concave regions of described concrete bed course.
The beneficial effects of the utility model are: after adopting said structure: arrange enhancement Layer under sole plate, effectively stop the high hydraulic pressure of underground water, avoid the generation of ater-casting Seepage.Ensure the validity of position, ater-casting sole plate thickness of protection tier, ensure that the durability of structure.Decrease the cleaning work amount of foreign material in ater-casting and ponding, lower workman's labor intensity, improve post empiricism quality, reduce labor workload, there is very considerable economic benefit and social benefit.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment technical scheme, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only that the utility model is in order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below the accompanying drawing used required in p-embodiment or description of the prior art is briefly described, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of deep foundation post empiricism structure as shown in Figure 1, comprises the concrete bed course (1) in spill, is provided with enhancement Layer (2) in the concave regions of described concrete bed course (1), base plate (3) based on described enhancement Layer (2) top.
This ater-casting operates according to the following steps when constructing:
1, line setting: adopt transit unwrapping wire, from oriented axial control network, measure out position, ater-casting, determine the accurate location of ater-casting, put bed course size outside from position, ater-casting, squeeze into spacer bars around the corner, draw and establish nylon wire, spill lime line.According to the lime line of location, dig to design elevation under adopting artificial vertical, the degree of depth is generally easy is 650mm, measures cutting depth with level gauge and Sopwith staff simultaneously.From ater-casting, the position line measures outer unwrapping wire accurately, squeezes into spacer bars at turning, draws and establishes nylon wire, spills lime line; At the bottom of from outer edge lime line to the ater-casting of having excavated, obliquely excavate the unnecessary earthwork or sandstone.After excavation, certain finishing is carried out to groove.The local place of backbreaking should backfill.Frog hammer ramming more than three times is back and forth adopted to substrate, inclined-plane is made real, guarantee the groove earthwork or sandstone closely knit, concrete bed course (1) has been constructed.
2, enhancement Layer (2) structure construction: concrete bed course (1) has been constructed and started enhancement Layer (2) structure of constructing on the 3rd day.Enhancement Layer (2) general thickness is easily 300mm, and reinforcement cover controls at 50mm, first places longitudinal reinforcement 12, can carry out overlap joint colligation according to 30d, and then place cross direction profiles muscle, vertical lateral dimension is generally easy is 200mm × 150mm, and reinforcing bar binding is even.Acceptance(check) after reinforcing bar binding, starts to build C30 concrete, with watering with the Troweling press finishing that vibrates.Build complete covered with plastic film and woollen blanket carries out maintenance.
3, rubber water-proof sheet construction: with the thick rubber water-proof sheet of paving 10mm, rubber water-proof sheet width is preferably outside both sides, ater-casting and puts >=200mm.Rubber water-proof oblique cut grafting length is no less than 200mm, and the full glue of glue special connects.After rubber water-proof sheet is laid, lay 6.5@150mm × 150mm reinforced mesh on top, lateral length is put 250mm outside the size of ater-casting.
4, fish tail and waterproof layer construction: construction waterproof cover concrete, with watering with the Troweling press finishing that vibrates.Build complete covered with plastic film and woollen blanket carries out maintenance.
5, sole plate (3) construction: after topping construction; first use and a concreting 50mm wide same base plate protection layer the same thick coagulation earth steps of basis with label; control thickness of protection tier, after intensity reaches, carry out steel mesh reinforcement colligation under base plate again.Ф 12 longitudinally fixing reinforcing bar is longitudinally set at position, ater-casting before the colligation of baseplate reinforcing bar net, in altitude range every 100mm together, for the steel fabric sheet of blocking in the altitude range of ater-casting, after treating bottom layer of the reinforcing steel colligation, be spot welded on bottom layer of the reinforcing steel with vertical reinforcement and be fixed, vertical reinforcement longitudinally every 500mm together.In the altitude range of ater-casting, carry out lock raft by upper and lower two pieces of close order double-layer wire mesh sheet, in sole plate (3) reinforcing bar bottom range, increase by one stiffened wire lath, with shutoff lateral bottom plates concrete.
Sole plate (3) middle part increases by one steel plate waterstop strip, and steel plate waterstop strip jointing adopts full weld.After bottom reinforcement bars construction, measure the horizontal absolute altitude of waterstop, adopt welding 6.5 reinforcing bar to fix.
Sole plate (3) concrete is poured into a mould, and before treating concrete final set, the cement paste of removing inflow ater-casting, covers double-deck colour bar cloth and bamboo slab rubber is protected, and falls in ater-casting to prevent foreign material.The order from centre to both sides is easily followed in sole plate (3) concreting, is conducive to ponding and discharges to surrounding.
6, ater-casting capping protection: apart from basic ater-casting 100mm place, every limit cement mortar smear the checkdam of a 50mm × 50mm or build 2 skin common brick cement mortar by laying bricks or stones and whitewash, upper enclosure plank.Ater-casting is entered to prevent construction water and foreign material.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
