Description
Technical field
The utility model relates to a kind of underground building structure, specifically refers to the architectural construction of a kind of underground radiation proof rigid self-waterproof.
Background technology
The immediate cause producing subterranean tunnel infiltration has three: 1. tunnel space enclosing structure exists penetrating passage; 2. the infiltration water source that hydraulic pressure is enough large is had; 3. infiltration water source communicates with penetrating passage.These three factors just produce infiltration when jointly existing, and therefore can think that there is direct relation in the infiltration of underground structure and crack.And the generation in crack is except the load stress of probability that accounts for 30% and differential settlement, mainly because concrete shrinkage, shrinkage and creeping causes, this with concrete physics, chemical property is relevant.
Existing waterproof technique mainly contains rigid waterproofing and flexible water two type.Rigid waterproofing mainly refers to the waterproofing course using rigidity water-proofing material, and this kind of rigid material mainly contains fibrous concrete waterproofing materials, prestressed concrete waterproofing materials, pea gravel concreten waterproofing materials etc.Flexible water is then the main body waterproofing materials using the material such as malthoid and pitch to manufacture.The advantage flexible of flexible waterproof layer, can adapt to certain distortion and breathing, not easy to crack.Shortcoming is that service life is short, and existing flexible water technology is only 10 ~ 20 years the longest service life.And relatively stricter to the requirement of basal plane, must construct on completely smooth, bright and clean, that water content is below 9% basal plane, otherwise just there will be the situation of layering, a drum, channeling water.
Traditional rigid waterproofing technology refers to cement, sand, stone as raw material, mix a small amount of Admixture or high molecular polymer, by adjustment match ratio, improve pore structure, increase the density at a raw material interface, or pass through compensate for shrinkage, improve the methods such as concrete impervious leakage prevention, make concrete structures reach the technology of waterproof.The feature of rigid waterproofing technology takes diverse ways according to different engineering structuress, and construction is simple, convenient, and cost is lower, for ease of maintenaince, and waterproof good endurance.So in conventional civil construction, rigid waterproofing accounts for sizable ratio.But the shortcoming of conventional rigid waterproof is also comparatively obvious, is in self highdensity reason and causes rigid waterproofing deadweight larger.And rigid waterproof layer is once occur dry green deformation, crack phenomenon, so waterproofing course also will be impaired.
Conventional rigid waterproof type has the following two kinds:
(1) rigidity water-proofing material is utilized to carry out waterproof
The main base material of rigid waterproofing is cement, as portland cement, Portland cement, slag cements, trass cement.The impermeability of these hydraulic cementing materials and waterproof durability are all good, so domestic and international many waterproofings all adopt cement as cementitious materials.But, because the tensile strength of cement is low, be out of shape little, be easy to shrinkage cracking, often destroy the integral waterproofing of structure.And after cement becomes concrete, the many pore seams of inner formation, become the passage of infiltration.
In order to improve concrete impermeability, domestic and international scientific and technical personnel work out many inorganic water-proof agents, as ferric trichloride, inorganic aluminate, triethanolamine etc.By adding these waterproof agents, improving the density of cement mortar or improving the crack resistance of mortar, thus reaching the object of water proof anti-seepage.But these measures cannot stop seepage completely.
(2) impermeable structure
Impervious prerequisite is cracking resistance, and common waterproof concrete and Admixture waterproof concrete do not have expansion character, and they do not have anti-cracking function, even if their impermeability is very high, Shrinkage Cracking of Concrete also just loses integral waterproofing function.
Impermeable structure technology is by expansive cement and cement and expanded or Shi Hanzhang, the whole or most of tensile stresss making compressive pre-stress can offset structure to produce in contraction process.But the more difficult corner of expansive concrete, the irregular occasion in cross section; Although Shi Hanzhang better can solve waterproof problem, construction is complicated, and cost is very high.
Intense radiation nuclear equipment comprises atomic energy industry and the isotopic device of application of radiation, as reactor, accelerator, radiochemistry device, customs, hospital etc., there is intense radiation core in these radiation kernel equipment, severe contamination can be caused to underground water, therefore the safeguard structure of carrying equipment is needed to shield ray, and there is extremely strong water resistance, require that outside underground water must not infiltrate equipment scope peripheral extent.
α, χ can be covered, gamma-rays and neutron current etc. have the concrete of harm to be called radiation shield concrete to human body, the tunnel of the isolated radiation constructed thus is referred to as radiation shield concrete tunnel, radiation shield concrete tunnel generally adopts the high density concrete that density ratio ordinary concrete is large, its apparent density≤2800kg/m
3.High density concrete is formulated by cement, water and heavyweight aggregate, and concrete is heavier, and wall is thicker, and its protection X, gamma-ray performance are better.
In reality, because high density concrete is expensive and not easily purchase, and thicker ordinary concrete wall also possesses the function of isolated radiation the same as high density concrete, therefore often adopts ordinary concrete to replace high density concrete.But the isolation effect of ordinary concrete is poor more than high density concrete, reach desirable isolation effect, safeguard structure thickness at least needs 1m.And atomic power device required precision is high, require that space enclosing structure must grow distance sequential production.Under the requirement that this is harsh, need sequential production and thick and heavy ordinary concrete component drying shrinkage is obvious, the heat of hydration is large, is difficult to generation and the crack progressing of control critical eigenvalue.Therefore there is a large amount of cracks in tunnel wall, depends sidewall alone and cannot realize rigid waterproofing.Although flexible water can be filled crack and reach good waterproof effect, but its life-span only has at most 20 years, the atomic energy industry device being embedded in underground can not excavate every 20 years and again do a waterproof construction, therefore need a kind of technology reach can radiation proof, again can absolute waterproof.
The existing rigid waterproofing scheme stopping concrete water-permeating mainly contains two kinds:
(1) inner embedding steel plate
Existing conventional concrete tunnel 100 as shown in Figure 1, is built formed by concrete and reinforcing bar 101, steel tie 102.In order to stop concrete water-permeating, the concrete tunnel 200 of built-in embedding steel plate as shown in Figure 2, embedding built-in steel plate 202 between reinforcing bar 201, and be welded into an overall after-pouring concrete, this is equivalent to make a steel box, utilizes the exhausted water-based of steel plate to carry out waterproof.This method makes safeguard structure have good waterproof, water isolating really, but there is obvious shortcoming: 1. steel need welding to cause the steel plate of taking can not be too thin, thickness is generally greater than 3 ~ 5mm, causes structural steel amount huge, and overall cost is 3 ~ 6 times of conventional concrete construction.2. the embedding steel plate of inside concrete causes the tension rib between the reinforcing bar of interior outside to arrange, very large to concrete side walls stressing influence.3. embedding steel plate is higher to concreting technological requirement, needs two-step pouring concrete and need ensure that the concrete of building for the first time is very smooth, intact to ensure steel plate laminating.
(2) Shi Hanzhang
By stretch-draw prestressing force steel bundle, apply precompression to concrete structure, effectively can prevent concrete cracking.But Shi Hanzhang requires higher to concrete intensity, Creep Characteristics, and a large amount of stretch-draw prestressing force steel Shu Zaocheng constructs, very difficulty and cost promote 2 ~ 3 times.

The operating principle of each parts of the utility model self waterproofing architectural construction is as follows:
1. there is the bucker top cover 21 of guiding gutter
The top cover 21 of bucker is constructed by the profiled sheet 211 of warpage and steel concrete 212 and is formed, and profiled sheet 211 has the guiding gutter 211a that cross section is isosceles trapezoid.Top cover 21, when constructing, is first laid profiled sheet 211, then assembling reinforcement on profiled sheet 211, and is built the waterproof concrete on top on the top board 11 of heavy wall concrete tunnel, construction simple and fast, with low cost.
When profiled sheet 211 does not have corrosion saturating, profiled sheet 211 plays exhausted water effect to outside underground water, make heavy wall concrete tunnel can completely cut off underground water completely, as shown in Figure 8, outside underground water is when outside saturated clays 6 infiltrates profiled sheet 211 upper surface, profiled sheet 211 guides the infiltration of infiltrating profiled sheet upper surface into two ends along the length direction of guiding gutter, the infiltration of guiding two ends into carries out underground water collection in the internal face inflow catch basin 4 of the side cover 22 of bucker, then by underground water centralized detecting treating apparatus, the underground water collected in catch basin 4 is detected and processed.
Permanent when the time, profiled sheet 211 is by after corrosion, the guiding gutter 211a in the middle of profiled sheet 211 is utilized to carry out pressure release to the underground water infiltrating profiled sheet guiding gutter 211a, as shown in Figure 9, after profiled sheet 211 corrodes, profiled sheet 211 guides the infiltration entered in profiled sheet guiding gutter into two ends by guiding gutter 211a, the infiltration of guiding two ends into carries out underground water collection in the outside wall surface inflow catch basin 4 of the tunnel-side 12 of heavy wall concrete tunnel, then by underground water centralized detecting treating apparatus, the underground water collected in catch basin 4 is detected and processed, thus make heavy wall concrete tunnel can completely cut off underground water completely.
Therefore, arrange profiled sheet 211, no matter whether profiled sheet 211 is by corrosion, and can both ensure that heavy wall concrete tunnel can completely cut off underground water completely, prevent the ground water seepage of radiation kernel equipment 7, the waterproof life-span is consistent with structural life-time, can reach more than 50 years.

2. the side cover 22 of bucker
The concrete side cover 22 of bucker both sides is thinner, effectively can reduce the heat of hydration of tunnel-side and the impact of contraction, and side cover 22 uses conventional waterproof concrete, can reach good waterproof effect.But bucker can not completely cut off the infiltration of outside underground water completely, when profiled sheet 211 is not saturating by corrosion, infiltration is covered 22 inwalls along side and is flowed to catch basin 4, and the current direction underground water centralized detecting treating apparatus of catch basin 4, discharges without after nuclear pollution after testing again.
By bucker 2, outside underground water just cannot touch inner heavy wall concrete tunnel 1, and the accurate radiation kernel equipment 7 being positioned at heavy wall concrete tunnel 1 inside is also protected, and plays the effect of 100% completely isolated underground water.
3. heavy wall concrete tunnel and bucker acting in conjunction
The heavy wall concrete tunnel 1 of heavy wall concreting, maximum advantage to completely cut off radiation.When tunnel wall is thicker, can stop that Radiolucent sidewall that inner core equipment produces is toward external radiation, that is, has more thick and heavy concrete side walls completely, inner core radiation just cannot pollute the underground water beyond the underground water and bucker of outside infiltration, reaches the effect of stopping nuclear pollution.
But because radiation kernel equipment 7 pairs of tunnel rigidity requirements are high, tunnel needs continuously the large scale of construction to build, and can not establish many structural joints as common municipal tunnel and separately build, cause concrete shrinkage, hydration heat effect obvious especially.Experiment shows, when building with conventional concrete, tunnel-side and roof and floor, concrete cracking is more serious.If therefore do not make bucker, waterproof of singly taking measures on concrete, it is almost impossible for reaching absolute waterproof.
Bucker 2, in order to reduce shrinkage crack, reduce the heat of hydration and design thinner, keeps out the limited in one's ability of outside soil pressure.The sidewall of inner heavy wall concrete tunnel 1 designs thicker to isolate ray, and rigidity is better.Therefore carrying out support-side cover 22 by arranging many connecting rods 5 between side cover 22 and tunnel-side 21, bucker 2 and heavy wall concrete tunnel 1 being connected to form an overall structure, making it jointly stressed.Bucker 2 provides the effect of waterproof and opposing soil pressure, and heavy wall concrete tunnel 1 provides radiation proof and supports the stressed double action of bucker 2, and both common co-ordinations, realize the effect that 1+1 is greater than 2.
4. the U-shaped steel plate 3 set up
Traditional waterproof slab adopts flexible water or imbeds steel plate.Flexible water is effective, but the life-span only has 10 ~ 20 years, much smaller than structural life-time, again lays more difficult and effect is bad after damage.Imbedding steel plate then causes the tension rib in concrete slab between the reinforcing bar of outside to arrange, very large to concrete side walls stressing influence, and higher to concreting technological requirement.
The utility model at the bottom of cover 23 build after, directly lay thinner U-shaped steel plate 3 on top, then construct the substrate 13 of heavy wall concrete tunnel above.Set up the infiltration that U-shaped steel plate 3 effectively can completely cut off bottom underground water, to ensure again at the bottom of cover that the drawknot in 23 between reinforcing bar is not destroyed, and low to concreting technological requirement.U-shaped steel plate 3 only needs punching press just plastic, and only need weld between two blocks of U-shaped steel plates, welding capacity is few.
