Description

[Detailed Description of the Invention] (Purpose of the Invention) The present invention significantly shortens the on-site construction period, shortens the entire construction period, reduces human and time loss required for various intermediate inspections, and reduces the amount of time required for public work. This invention relates to a method and device for installing an underground tank storage facility, which aims to reduce the burden on fire department officials and prevent dangers caused by landslides.

(Prior Art) Conventionally, as shown in Figure 1, the installation method for underground tank storage facilities involves a water pressure test of the tank body (required 6 days) at the time of manufacturing the tank T at the construction stage. The outer surface of this tank T is coated with asphalt waterproofing A (glue) and transported to the fourth process (d) at the current MJIG (2).
days).

In parallel work, at site G, hole II was dug at the predetermined location permitted and stone stone S1 was laid. (B) (2 days)
. Assemble the temporary frame Wl and build the foundation concrete CB.

After completing the lower reinforcement inspection, the foundation,
Pour concrete C1, C2, and C3 for the pillows and pillars and cure for several days (c) (5 days). Next, install the tank T with the asphalt waterproofing treatment A brought in from the factory [1%1], fix it with bands B and B, and connect the detection tube (not shown) to the lorry ground (not shown) at a predetermined position fα. (Omitted) etc. and undergo installation inspection of Tank T (2) (2 days). Next, perform backfilling to the top of tank T and protector P.
Try it out, install oil piping L and L, undergo piping inspection, and apply corrosion-proofing treatment to the piping (E) (4 days). Next, support concrete c8. Perform backfilling M2 to the top of C3, assemble the upper concrete C4's bore 552, temporary frame W2 and reinforcing bars 1 (2), and undergo an upper inspection (3 days). Next, after completing the upper reinforcement inspection. , concrete C4 is poured and cured for several days ()-) (5 days).

Finish cleaning on the deepest diameter, W1! ! ! The entire process is completed by carrying out the inspection, installing the base plate enclosure and equipment, undergoing a final inspection, and receiving a certificate of completion inspection (3) (3 days).

With this conventional construction method, even if everything goes smoothly, it will take a total of 25 days to complete the construction work at Site C, which is too much work, and if it rains, it will take even longer.

Inspection was carried out once at factory ■, five times at site G, and ti
There are as many as 6 inspections, and if you divide the piping inspection into 2 inspections, you can get as many as 7 inspections. Because of the large number of inspections, there was a lot of loss in terms of both personnel and time for both those taking and administering the tests, and the burden on the inspectors was also heavy.

In addition, since the hole is not backfilled for several days after it is dug, not only is there a constant danger of the surrounding soil collapsing or people falling into it, but it also interferes with other construction work and disrupts the entire construction work process. In many cases, underground water gushes out, making it necessary to pump up the spring water over a long period of time, making it difficult to construct the foundations at the bottom.

Furthermore, it is likely that the concrete will be backfilled before it has sufficiently cured, resulting in problems regarding the strength of the concrete.

In addition, it actually needs to be carried out by a person who is familiar with the laws and regulations, and there is no way that anyone can carry out the construction.
Since the construction involves product production elements and uses non-modern construction methods, rationalization is necessary.

(#l Structure and Effect of the Invention) In view of the above-mentioned problems, the present invention can house an underground tank. A storage room made of standard concrete is completed in advance at the factory, a hole is dug at the permitted site, a griddle is laid, and concrete is poured for fixing the base, and the storage room is immediately installed, and after curing, the tank is installed. This invention is designed to carry out storage, piping, and backfilling in a short period of time.The present invention will be explained with reference to drawings of embodiments.

(Effects of the invention) The present invention manufactures various parts such as the JFT lower tank with asphalt lining on the tank body, supports, upper concrete, foundation concrete, detection tube, and base piping in a factory, and then performs drilling and greasing on site. After the stone paving and concrete pouring was completed, the foundation concrete and underground tank were transported together with a band, suspended in the hole, and leveled, and the supports were installed. Since the work of placing the upper concrete, installing the tray, protector, detector, base piping, etc., and backfilling work are performed in succession, the construction period on site is significantly shortened, and therefore the construction period of the entire construction work is shortened. The effect of bringing about good results is extremely large.

In addition, there is less human and time loss required for various intermediate inspections.
It can significantly reduce the burden on fire officials involved in official duties, shorten the period from digging a hole to backfilling it, greatly reduce the risk of surrounding earth and sand collapsing or causing people to fall, and using underground water pumps. Since the exercise period is shortened, there is less interference with the progress of other engineers.

Furthermore, on-site construction work in accordance with the enforcement standards stipulated by the Fire Service Act can be easily carried out even by those who are not particularly knowledgeable about it, and when manufacturing tanks and concrete parts in factories, uniform standards are used for each tank capacity. Since the dimensions are determined, produced and stocked in advance, concrete
1- The product can be sufficiently cured, and there are no defects in strength due to insufficient curing, which tend to occur with conventional construction methods.

In addition, since the concrete parts are designed with a rational design that differs from conventional construction methods, they have high physical strength and safety, are uniform in quality, are economical with no wastage of concrete, and are designed to streamline construction procedures. , on-site construction costs will also be significantly reduced.

Furthermore, both ends of the pillar are tapered, so
The connection between the foundation concrete and the upper concrete can be completely fixed without any wobbling.

Note that the underground tank storage facility of the present invention has a tank capacity of 3000
The limit is about 1.
