Specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Embodiment in based on the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.

Fig. 1 is referred to, the utility model provides a kind of technical scheme：A kind of ultra-long concrete for avoiding crack and seepage Structure, including Vertical Pile 1, cushion cap 2, support column 3, soil matrix layer 4, raft plate bed course 5, waterproof construction layer 6, fish tail and waterproof layer 7, brick wall 8th, coating 9, raft plate bar construction 10, raft board concrete 11,2 bottom surface of the cushion cap are fixed with multiple Vertical Piles 1, and top surface is solid Surely support column 3 is provided with, pile foundation is constituted, the pile foundation bottom is fixed in soil matrix layer 4, is equipped with above the soil matrix layer 4 Raft plate bed course 5, builds the brick wall 8 for having a closure, is set above the raft plate bed course 5 in the brick wall 8 successively above the raft plate bed course 5 There are waterproof construction layer 6 and fish tail and waterproof layer 7, above the fish tail and waterproof layer 7, be provided with raft plate bar construction 10, the raft slab muscle The support column 3 of structure 10 and the upper pilework is fixed, and fills raft board concrete 11 in raft plate bar construction 10 until by raft Plate bar construction 10 floods, and is provided with coating 9 above the raft board concrete 11；Described raft board concrete 11 by cement, sand, Stone, pumping admixture, flyash and polymer swelling fiber (SY-K) composition, the cement are the relatively low silicate cement of the heat of hydration Mud；On the basis of commerical ready-mixed concrete adding coal ash, pumping admixture, SY-K type polymer swelling fibers are filled.Polymer fiber Antimitotic agent is penetrated in concrete, as the good bonding of high molecular polymer and cohesive force uniformly can be mixed with concrete base-material Close, the density workability of Concrete Structure；Nearly 20 filametntary additions in cement mortar per cubic centimeter, in concrete sand Slurry is internally formed a kind of uniform unrest to support system, produces two grades of stiffening effects, contribute to slackening Plastic Shrinkage of Concrete and Stress during freeze thawing；Simultaneously countless filaments is formed disorderly to bracketing system in inside concrete, can effectively hinder aggregate Isolation, it is ensured that the water-retaining property of concrete early stage, so as to resist the formation of sedimentation crackle, mixes polymer fine compared with normal concrete Dimension anti-crack water-proof agent can effectively improve the anti-crack ability of concrete, while polymer swelling fiber anti-crack water-proof agent can strengthen The water proof anti-seepage ability of concrete, mixes a large amount of microfibres and can effectively suppress concrete early stage drying shrinkage fine fisssure in concrete And the generation and development of isolation crackle, particularly effectively suppress the generation of interconnected fracture, be evenly distributed in concrete phase each other A large amount of fibers of adhesion have played " support " aggregate, the bleed for reducing concrete surface and the isolation for gathering materials, so that In concrete, the voids content of a diameter of 50-100 nanometers is substantially reduced, and can be greatly enhanced impermeability；Described covering Layer 9 is plastic sheeting, wet gunnysack or polyphenylene heat insulation slab；While underplate concrete：Mix-design it is important that reduce the heat of hydration, For reducing the impacts of the shrinkage factor to distress in concrete such as hydration heat of concrete, refer to compression strength and durability on coagulation is met In the case of target, in folk prescription concrete, the consumption of the consumption of cement and Binder Materials should reduce as far as possible, as much as possible reduce water Mud consumption.SY-K swelling fiber anti-crack water-proof agents volume for (concrete and coal ash+breeze) total amount 8%.Hot weather construction concrete Presetting period substantially can shift to an earlier date, control concrete coagulating time, to concrete hydrating thermal control, the cold seam control of work progress System is all favourable, also can control the early strength development of concrete.Under normal temperature, the non-bulky concrete initial set time answers 12 little When more than；High temperature season (more than 28 DEG C of temperature) construct when and more than C5O concrete, answer more than 16 hours；Winter construction When, should not be early than 10 hours；When mass concrete should be condensed according to the situation of the actual concrete of temperature situation and scene Between adjustment.Concrete final setting time should not surpass 24 hours.In order to reduce the contraction of concrete, while improving impervious, control Water-cement ratio is particularly significant, should be by guaranteeing that from high-quality and efficient water reducer and control water-cement ratio the intensity of concrete meets design Require.

Although being described in detail to the utility model with reference to the foregoing embodiments, for those skilled in the art comes Say, which still can be modified to the technical scheme described in foregoing embodiments, or which part technical characteristic is entered Row equivalent, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvements that is made etc. all should It is included within protection domain of the present utility model.
