Description

A kind of water-proof repairing method of steel concrete squat silo roof
Technical field
The present invention relates to the construction method of water-proof repairing in Construction Technology field, particularly relate to a kind of water-proof repairing method of steel concrete squat silo roof.
Background technology
Silo be store grain, the vertical vessel of the bulk solids such as feed, coal, cement and ore, it has saving land for warehouses, is conducive to carrying out loading and unloading mechanization and automation, minimizing material loss and reducing dust to features such as the pollutions of environment, is widely used in industrial and agricultural production and accumulating department.Wherein reinforced concrete circular silo is Large Copacity storehouse type most widely used at present, and by ratio of height to diameter (grain storage height and the ratio of storehouse internal diameter), being dark storehouse (or vertical silo) when being more than or equal to 1.5, is shallow storehouse (or storehouse, shallow garden) when being less than 1.5.Silo is generally independent chamber, and each storehouse diameter can reach more than 18 meters, and height can reach more than 35 meters, and holding capacity of bin can reach more than 10,000 tons.Cang Ding is provided with the equipment such as trestle and various conveying, ventilation, and load is heavier.Hold Ceiling adopts conical monolithic reinforced concrete structure.
Because the storehouse addendum cone plate of silo and draining eaves gutter are that gradation is cast-in-place; both waterproofing process exist different; as shown in Figure 1; the classification of waterproof of storehouse addendum cone plate is generally II grade; employing twice are set up defences, and its structure (from bottom to up) is generally: reinforced concrete structure layer 1, and------------waterproof roll 5---insulation layer 6---pea gravel concreten is whole builds layer 7 to mortar cover 4 to waterproof coating layer 3 to mortar levelling layer 2.The classification of waterproof of draining eaves gutter is generally III grade, adopts and sets up defences together, its structure (from bottom to up) is generally: reinforced concrete structure layer 1---mortar levelling layer 2---waterproof roll 5---mortar cover 4.
Existing squat silo roof occurs that the reason of seepage can be summed up as the following aspects:
The first, there is constuction joint in squat silo roof superstructure, and this is the main cause of top, storehouse seepage, specifically comprises two aspects:
1, the constuction joint between storehouse addendum cone plate and draining eaves gutter.According to construction technology, squat silo roof Construction of The Superstructure flow process is: and bulkhead construction (sliding formwork) → storehouse apical ring beam 30, draining eaves gutter 20 construct → and storehouse addendum cone plate 10 constructs, as shown in Figure 2.Therefore, storehouse addendum cone plate 10, draining eaves gutter 20 and storehouse apical ring beam 30 are that gradation is cast-in-place, there is constuction joint 9 between storehouse addendum cone plate 10 and draining eaves gutter 20.
2, the constuction joint of nib periphery falls.When adopting the overall truss of assembling as storehouse top template support platform, the dismounting of truss platform generally adopts entire lowering mode, now at storehouse addendum cone plate 10(near storehouse apical ring Liang30Chu) on reserved several and fallen nib 14, as shown in Figure 4.The storehouse addendum cone board concrete falling nib 14 place is built falling after mould completes again.Therefore, fall nib 14 periphery and also there is constuction joint (not shown).
The second, storehouse top waterproof layer impaired inefficacy, cause the impaired inefficacy of waterproof layer because have thermal (temperature difference) stress, rain erosion and outside destroy three aspects.
1, between season in summer in winter two or there is the very large temperature difference round the clock summer, thermal (temperature difference) stress can cause waterproof layer to produce microcrack.
2, the typhoon season that the rainfall is plentiful damp and hot at high temperature, due to rain erosion and bulking, waterproofing course, insulation layer and whole layer of building easily are out of shape, play drum, cracking, cause waterproofing materials accelerated ageing and lose efficacy.
3, in rigging up and debugging process, sometimes also there will be boring, external impacts and vibration equipment, top, artificial damage storehouse waterproof layer.
Three, top, storehouse drainage system existing defects, comprises two aspects:
1, drain gully lazy weight.If storehouse roof fall mouth of a river lazy weight or appearance blocking, during heavy rain, impeded drainage can cause a large amount of ponding of draining eaves gutter, will slowly from structural weak infiltration storehouse after ponding soaks for a long time, and formation is leaked.
2, draining eaves gutter design elevation is too high.When draining eaves gutter is non-sunk type, namely the draining eaves gutter 20 of Cang Ding is with addendum cone plate 10 bottom, storehouse without the discrepancy in elevation, and as shown in Figure 2, the ponding in draining eaves gutter 20 forms seepage in putting in storage easily via the constuction joint infiltration of the weakness of structure.Otherwise, when draining eaves gutter is sunk type, as shown in Figure 3, then because ponding is in outside bulkhead, in not easily infiltration is put in storage.
In current existing routine techniques, the method of squat silo roof being carried out to water-proof repairing mainly carries out temporary repair for top, storehouse waterproof layer, owing to not processing the crack of the existence of storehouse roof construction layer itself, can not tackle the problem at its root, once waterproof layer lifetime expires lost efficacy, again will there is seepage again in Cang Ding, so mending-leakage effect is poor; In prior art, the method for leakage employing pipe laying slip casing by pressure is within doors also had to carry out mending-leakage, the method can only be suitable for when story height is little, and due to the particularity of silo structure, its storehouse inner height is often up to tens meters, indoor mending-leakage operation is carried out in high-altitude like this, difficulty of construction is very big, and high-altitude working safety is also difficult point, if construct in grain face in storehouse in the situation of buying securities with all one's capital, owing to there is dust explosion risk in closed bin, in storehouse, construction is forbidden.Therefore, find a technical feasibility, construction safety, technique water-proof repairing method that is simple, cheap, squat silo roof fast and effectively, there is realistic meaning.
