The nut protective cap has the function of preventing the nut from rusting and simultaneously increasing the attractiveness of the outer surface of the water tank. The nut protective cap has the function of preventing the nut from rusting and simultaneously increasing the attractiveness of the outer surface of the water tank.
The waterproof sealant is selected according to the material of the tank body, and the waterproof sealant 9 is coated at the lap joint of the bottom ring wall plate 4 and the bottom angle steel ring 5, and the bottom ring wall plate 4.
And step four, after the bottom ring wall plate 4 is connected with the bottom angle steel ring 5, installing a thin sizing block 12 between the bottom angle steel ring 5 and the concrete upper surface of the concave grouting groove 2 for leveling the wall plate of the water tank.
The bottom angle steel is adjusted according to the drawing design elevation, then the arc degree of the first belt plate is controlled through the circle center, the plate arc degree, the levelness and the elevation of the first ring are repeatedly checked for multiple times, and the drawing design requirement is met.
The thickness of the thin iron pad is 0.1-1 mm, the number of each group of iron pads is 2-12, and the thin iron pad is made of corrosion-resistant stainless steel; three groups of thin sizing blocks are arranged below each bottom ring wall plate.
And step five, after the levelness of the bottom ring wall plate 4 is qualified, pressing the angle steel fixing clamp 13 on the horizontal edge of the bottom angle steel ring 5, and fixing the angle steel fixing clamp 13 at the bottom of the concave grouting groove 2 by using the expansion bolt 6, so that the angle steel fixing clamp 13 tightly presses the bottom angle steel ring 5.
The angle steel fixing clip 13 generally adopts inequilateral angle steel, and a hole for installing the expansion bolt 6 is arranged on the long edge. The expansion bolts are generally M20-M26, the length of the expansion bolts is determined according to the depth of a foundation groove, and the angle steel fixing clips 13 are used for pressing the bottom angle steel ring 5. The lower part in the concave grouting groove 2 is set to be a reinforcement-free area, so that the expansion bolt 6 can be conveniently installed. Each bottom ring wall plate 4 has three sets of fixing members consisting of angle steel fixing clips 13 and expansion bolts 6, as shown in fig. 6.
Installation of the tank body: according to the storage tank normal installation construction method, other circles of tank wall plates, top ring tank walls and edge-covered angle steel, edge-covered angle steel and a tank top, tank top installation, connecting pipe installation and ladder railing platform installation are carried out.
And step six, sticking a water stop belt above the connecting bolt 7 of the bottom ring wall plate 4 and the bottom angle steel ring 5.
Before the water stop tape is pasted, the sealing plaster, the water vapor and the dust on the bottom ring wall plate are cleaned by dry cotton cloth. In a preferred embodiment, two circles of water stop tapes are adhered to the inner wall of the bottom circle wall plate in the concave grouting groove 2, the upper circle is a bentonite-containing rubber water stop tape, namely a bentonite water stop tape 10, and the lower circle is a water stop tape 11, as shown in fig. 5.
And step seven, sticking a circle of water stopping adhesive tape 11 at the middle position of the inner side wall of the concrete concave grouting groove 2.
Relatively specifically, be clean up concrete concave type grout inslot lateral wall with dry cotton, then paste round stagnant water sticky tape 11 along the inslot lateral wall from the position of tank bottom distance half, as shown in fig. 5 and 6, prevent that there is the infiltration passageway with basis, board after the foundation trench secondary grout to avoid appearing the seepage phenomenon.
In the sixth step and the seventh step, the waterproof principle of the bentonite waterstop 10 is that bentonite particles in the adhesive tape expand when encountering water, so that the bentonite waterstop is extruded and compacted between the tank wall and the concrete to play a waterproof role. Similarly, the water-stopping adhesive tape is a novel waterproof material with self-adhesive property, which is synthesized by high polymer, inorganic water-absorbing expansion material, rubber and auxiliary agent. The water-stopping adhesive tape is tightly mixed with concrete and the wall of the tank after water absorption and expansion, so that a water seepage channel is blocked, and a water-stopping effect is achieved. The joint form between the water stop adhesive tapes comprises lap joint, butt joint and composite joint. The rubber waterstop is installed on the tank wall and the side wall of the concrete foundation by generally adopting bonding, fixture fixing and template fixing.
With bentonite waterstop and stagnant water sticky tape pasting jar bottom circle wallboard and concave type grout groove lateral wall, when the water pitcher wallboard had the infiltration clearance with the pea gravel concreten grout blanket, water seeped to the position of pasting the waterstop, and the waterstop begins the inflation after absorbing water, will seep water the closely knit waterproof effect that plays of space extrusion, avoids the water pitcher basis to take place the seepage to a certain extent.
And step eight, after the water-stopping adhesive tape 11 is installed, performing secondary grouting on the inner side 2-2 of the tank wall and the outer side 2-1 of the tank wall of the concave grouting tank by using concrete.

In the secondary grouting process, whether the water-stopping adhesive tape falls off or not is noticed at all times, and if the water-stopping adhesive tape falls off, the falling off adhesive tape is cut off and replaced by a new one. Meanwhile, the water-stopping adhesive tape is completely buried by the non-shrinkage fine aggregate concrete. In the process of positioning the water-stop adhesive tape and tamping concrete, attention should be paid to the positioning method and the tamping pressure so as not to damage the adhesive tape.
After the bolt connection type water tank is installed, a water injection test is carried out to check the tightness of the tank bottom, the strength and tightness of the tank wall and the observation record of foundation settlement, and the test time is 48 hours.
