Description
本発明は、受水槽を修理する期間、受水槽の代わりに使用する仮設受水槽に関する。 The present invention relates to a temporary water receiving tank used in place of a water receiving tank during a period of repairing the water receiving tank.
本願発明者は、給排水設備、公害処理設備等の設計・施工、更にそれらの修理・点検等を業とする会社を長年運営してきている。その間、地方公共団体等の上下水道やプールの修理も数多く行なってきた。その経験の中で、本願の課題である受水槽を修理するときの仮設受水槽を思いついた。 The inventor of this application has been operating a company for many years that designs and constructs water supply and drainage facilities, pollution treatment facilities, etc., and also repairs and checks them. During that time, many repairs of water and sewage systems and pools by local governments have been carried out. In that experience, I came up with a temporary water tank when repairing the water tank, which is the subject of this application.
受水槽とは、ビル・マンション・学校・病院などや一時に多量の水を使用する建物などで、水道局から水道管を通って送られてきた水を、いったん貯めておく容器（タンク）のことである。マンションや学校等の集合建築物では、使用人数が多いため、給水栓での安定した水圧を維持でない場合がある。そこで、水道水(上水)を受水槽に受け、揚水ポンプで高架水槽へ揚水した水を、又は、貯水槽に連結した加圧ポンプにより加圧された水を、共用給水管を通し、各給水栓へ給水している。この受水槽は、水道法等の規定により、所定の大きさを超える場合には、定期検査や清掃の実施等が義務づけられ、また受水槽の構造等も規定されている。 Receiving tanks are buildings, condominiums, schools, hospitals, and other buildings that use a large amount of water at a time, and are used to store water that has been sent through water pipes from the Waterworks Bureau. That is. In a collective building such as a condominium or a school, since there are many users, stable water pressure at the hydrant may not be maintained. Therefore, tap water (water supply) is received in the receiving tank, the water pumped up to the elevated water tank by the pump or the water pressurized by the pressurizing pump connected to the water tank is passed through the common water supply pipe, Water is being supplied to the tap. This water tank is required to carry out periodic inspections and cleaning, etc., if the size exceeds a predetermined size, and the structure of the water tank is also specified.
受水槽は、コンクリート（RC）、金属（ステンレスもしくは鋼製）、樹脂（FRP等）で製作され、施錠付きのマンホール、定水位弁、オーバーフロー管、通気口、水抜き管等から構成されている。受水槽も経年変化により、水漏れ、ワレ、塗膜剥離等が生ずる。新しく受水槽を作るには、有効容量が１０ｍ³を越えるものでは、製作費が約２０００万円以上掛かるとされている。その経費を節減するため、受水槽は、新たに製作するのではなく、修理することを余儀なくされている。受水槽の修理では、新たに受水槽を製作する場合と比較し、約１／５〜１／６の経費で済むためである。しかし、修理は、受水槽の中に人が入り、水漏れやワレ・歪等の補強、張替、パテ塗り、塗装等の作業をしなければならず、その修理の間は受水槽が使用できず、マンションや学校等の集合建築物での給水栓は、給水を受けることができず、その活動が停止せざるを得なくなる。そこで、受水槽を修理する間、仮設の受水槽を設け、ここより各給水栓への給水を行なう必要が生じる。仮設の受水槽では、組み立て、解体・撤去が容易で短時間ででき、既設の揚水ポンプや加圧ポンプを利用することが必要である。こうした仮の受水槽に関する先行技術文献を調査したが、直接関連する先行技術文献は見当たらなかった。しかし、何らかの関係があると思われる先行技術文献としては、以下のようなものが見受けられた。 The water receiving tank is made of concrete (RC), metal (stainless steel or steel), resin (FRP, etc.), and consists of a locked manhole, constant water level valve, overflow pipe, vent, drain pipe, etc. . Also in the water receiving tank, water leakage, cracking, peeling of the coating film, etc. occur due to aging. In order to make a new water receiving tank, if the effective capacity exceeds 10 m ³, the production cost is said to be about 20 million yen or more. In order to save the cost, the water tank is forced to be repaired instead of being newly manufactured. This is because repair of the water receiving tank requires about 1/5 to 1/6 of the cost compared to the case of newly manufacturing the water receiving tank. However, repairs require people to enter the water tank and reinforce water leaks, cracks, distortion, etc., and rework, putty, and painting. The water tank is used during the repair. However, the faucets in apartment buildings such as condominiums and schools cannot receive water, and their activities must be stopped. Therefore, it is necessary to provide a temporary water receiving tank during the repair of the water receiving tank, and supply water to each water tap from here. Temporary receiving tanks can be easily assembled, disassembled and removed in a short time, and it is necessary to use existing pumps and pressure pumps. Prior art documents related to these temporary water receiving tanks were investigated, but no directly related prior art documents were found. However, as the prior art documents that seem to have some relationship, the following were found.

FIG. 3A is a schematic view when a water receiving tank is used, and FIG. 3B is a schematic view when a temporary water receiving tank 1 is used. The water receiving tank 2 is connected to an existing water supply pipe 91 and a pressurizing pump or a pumping pump 4 to the elevated water tank 3 (hereinafter, a pumping pump to the elevated water tank is referred to as a pumping pump). The temporary water receiving tank 1 is installed in a place where the existing water supply pipe 91 and the pressurizing pump 5 or the pumping pump 4 can be piped. And the piping 11 construction which connects the temporary water receiving tank 1 and the existing water supply pipe 91 and the pressurization pump 5 or the pumping pump 4 is performed. After predetermined operations such as cleaning and disinfection in the temporary water receiving tank 1 are completed, water is supplied to the water receiving tank 2 and from the water receiving tank to the pressurizing pump 5 or the pumping pump 4 (indicated as 4 or 5 in FIG. 3). Shut off water supply. Water is supplied into the temporary water receiving tank, and the water is supplied from the temporary water receiving tank 1 to the water tap 7 through the common water supply pipe 6 by the pressurizing pump 5 or the pumping pump 4. After repairing the water receiving tank (including cleaning and disinfection in the water receiving tank), remove the temporary water receiving tank, the temporary water receiving tank, the existing water supply pipe 91 and the piping 11 of the pressure pump 5 or the pumping pump 4 and repair. The subsequent water receiving tank and the existing water supply pipe 91 and the pressurizing pump 5 or the pumping pump 4 are connected to return to the original state. Remove the temporary water tank and complete the water tank repair work. Although FIG. 3 shows the opening / closing valve 12, the present invention is not limited to this, and any method that shuts off the water supply is sufficient regardless of the presence / absence of the opening / closing valve 12.
仮設受水槽１は、架台８上に設置することが望まれる。設置場所の地面の凸凹を、架台８の脚で調節し、また、後述するが、架台８を用いて仮設受水槽１内の水位を加圧ポンプ５又は揚水ポンプ４より高くしておくためである。 It is desirable that the temporary water receiving tank 1 be installed on the gantry 8. The unevenness of the ground at the installation location is adjusted by the legs of the gantry 8, and as will be described later, the water level in the temporary water receiving tank 1 is set higher than the pressurizing pump 5 or the pumping pump 4 by using the gantry 8. is there.
続いて、第２発明は、ステンレス製の所定寸法の天板、底板、側板の各パネルをつなぎ合せ直方体とし、給水管及び加圧ポンプ又は高架水槽への揚水ポンプとの配管用の開口部、通気管、マンホールとを設けた第１発明の仮設受水槽である。 Subsequently, the second invention is a rectangular parallelepiped connecting the panels of the top plate, the bottom plate, and the side plate made of stainless steel with predetermined dimensions, and an opening for piping with a water supply pipe and a pressure pump or a pump to the elevated water tank, It is the temporary water receiving tank of the 1st invention which provided the vent pipe and the manhole.
仮設受水槽は、立体的な容器(タンク)の状態で搬送することは困難であり、仮設受水槽を組み立てる部品等を現地に搬送する。そして、仮設受水槽は、組み立て、解体・撤去作業が、容易で、かつ、短時間で終了する必要がある。一方、仮設受水槽は、使い捨てではなく、限度はあるが、何回も使用できることが望まれる。また、内部の洗浄・消毒がし易く、衛生的であることが必要である。そこで、ステンレス製の所定寸法の天板、底板、側板の各パネルを用意し、現地にてこれらをつなぎ合わせ、直方体の容器とすることとした。各パネルを予め準備し、現地で組み立てる方法は、運搬も容易であるし、現地での組み立ても、２人ですることができる。また、仮設受水槽ではあるが、受水槽の修理期間中は、受水槽と同じ機能を果たすため、水道法等の規定に従い、給水管及び加圧ポンプあるいは揚水ポンプとの連結配管用の開口部と通気管、マンホールとを設けている。 It is difficult to transport a temporary water receiving tank in a three-dimensional container (tank) state, and parts and the like for assembling the temporary water receiving tank are transferred to the site. The temporary water receiving tank needs to be assembled and disassembled / removed easily and completed in a short time. On the other hand, the temporary water receiving tank is not disposable and has a limit, but it is desired that it can be used many times. Moreover, it is necessary to be easy to clean and disinfect the inside and to be hygienic. Therefore, the top plate, the bottom plate, and the side plate made of stainless steel having predetermined dimensions were prepared, and these were joined at the site to form a rectangular parallelepiped container. The method of preparing each panel in advance and assembling it on site is easy to carry and can be assembled on site by two people. In addition, although it is a temporary receiving tank, it has the same function as the receiving tank during the repair period of the receiving tank. A ventilation pipe and a manhole are provided.
図４、５、６は、仮設受水槽１の正面概略図、平面概略図、側面概略図である。ステンレス製の所定寸法の天板１０１、底板１０２、側板１０の各パネルをつなぎ合せ、直方体としている。各パネルは、ボルトとナットによりつなぎ合せ、更に、底板１０２、側板１０は、ボルトとナットにより架台にもつなぎ合せている。なお、各パネルをつなぐ方法は任意である。パネルとパネルのつなぎ目は、コーキング剤により水漏れを防いでいるが、これに限るものではない。 4, 5, and 6 are a schematic front view, a schematic plan view, and a schematic side view of the temporary water receiving tank 1. The stainless steel top plate 101, the bottom plate 102, and the side plate 10 are connected to each other to form a rectangular parallelepiped. Each panel is connected by a bolt and a nut, and the bottom plate 102 and the side plate 10 are connected to a frame by a bolt and a nut. In addition, the method of connecting each panel is arbitrary. The joint between the panels prevents water leakage with a caulking agent, but is not limited to this.
続いて、第３発明は、仮設受水槽内面の相対する側板どうしを補強ブレスで底板に対し水平に連結した第２発明の仮設受水槽である。 Subsequently, the third invention is the temporary water receiving tank of the second invention in which the side plates facing each other on the inner surface of the temporary water receiving tank are connected horizontally to the bottom plate with a reinforcing brace.
仮設受水槽内の側板内面にかかる水圧に耐えるため、仮設受水槽内面の相対する側板どうしを、補強ブレスで底板に対し水平につなげている。図５の仮設受水槽１の平面図において、側面の高さの略中央に、短辺に平行に３本、長辺に平行に１本、補強ブレス１０３がつながれている。 In order to withstand the water pressure applied to the inner surface of the side plate in the temporary water receiving tank, the opposing side plates on the inner surface of the temporary water receiving tank are connected horizontally to the bottom plate with a reinforcing brace. In the plan view of the temporary water receiving tank 1 in FIG. 5, three reinforcing braces 103 are connected in parallel to the short side and three in parallel to the long side at the approximate center of the side surface height.
続いて、第４発明は、仮設受水槽内の水位が常に一定の高さに維持できる水位維持装置を設けた第２発明又は第３発明のいずれかの仮設受水槽である。 Subsequently, the fourth invention is the temporary water receiving tank of either the second invention or the third invention provided with a water level maintaining device capable of always maintaining the water level in the temporary water receiving tank at a constant height.
仮設受水槽１内の水位が既設の加圧ポンプ５あるいは揚水ポンプ４より低くなると、加圧ポンプ５あるいは揚水ポンプ４は、前述のように空気が巻き込まれ、これらのポンプが動かなくなる恐れがある。そこで、仮設受水槽１内の水位をこれらのポンプより高い位置に常に維持しておくため、水位維持装置を設けるものである。水位維持装置としては、図２にあるような定水位弁２３が代表的なものであるが、これに限るものではない。 When the water level in the temporary water receiving tank 1 becomes lower than the existing pressurization pump 5 or the pumping pump 4, the pressurization pump 5 or the pumping pump 4 is entrained with air as described above, and these pumps may not move. . Therefore, in order to always maintain the water level in the temporary water receiving tank 1 at a position higher than these pumps, a water level maintaining device is provided. As a water level maintaining device, a constant water level valve 23 as shown in FIG. 2 is representative, but it is not limited to this.
続いて、第５発明は、仮設受水槽内の水位が、常に加圧ポンプあるいは高架水槽への揚水ポンプより高く維持するため、架台上に固定した、第２発明、第３発明又は第４発明のいずれかの仮設受水槽である。 Subsequently, the fifth invention is the second invention, the third invention or the fourth invention fixed on the gantry in order to keep the water level in the temporary receiving tank always higher than the pressurization pump or the pumping pump to the elevated water tank. This is a temporary water receiving tank.
第４発明と同じように、仮設受水槽内の水位が、常に加圧ポンプあるいは高架水槽への揚水ポンプより高く維持するため、仮設受水槽を架台上に固定するものである。また、架台は、仮設受水槽を設置する地面の凹凸を吸収するための機能も備えている。 As in the fourth invention, the temporary water receiving tank is fixed on the gantry in order to keep the water level in the temporary water receiving tank always higher than the pressurizing pump or the pumping pump to the elevated water tank. The gantry also has a function for absorbing irregularities on the ground where the temporary water receiving tank is installed.
続いて、第６発明は、架台上に仮設受水槽を固定し、仮設受水槽と既設の給水管及び加圧ポンプ又は揚水ポンプとを配管によりつなぎ、仮設受水槽内の清掃・消毒作業後、受水槽と給水管及び加圧ポンプ又は高架水槽への揚水ポンプとの連結を遮断し、仮設受水槽に上水を給水し、仮設受水槽から給水栓へ給水を開始した後、受水槽の修理を開始し、受水槽の修理が完了した後、受水槽と既設の給水管及び加圧ポンプ又は揚水ポンプとをつなぎ、受水槽の使用を復旧させるまでの、仮設受水槽を利用する作業手順である。 Subsequently, the sixth invention is to fix the temporary water receiving tank on the gantry, connect the temporary water receiving tank and the existing water supply pipe and the pressurization pump or the pump to the pump, and after cleaning and disinfecting work in the temporary water receiving tank, After disconnecting the connection between the water receiving tank and the water supply pipe and the pressure pump or the pump to the elevated water tank, water is supplied to the temporary water receiving tank, water supply from the temporary water receiving tank to the water tap is started, and then the water receiving tank is repaired. After completing the repair of the water receiving tank, connect the water receiving tank with the existing water supply pipe and the pressurization pump or pump, and use the temporary water receiving tank until the use of the water receiving tank is restored. is there.
仮設受水槽は、短時間に組立し、受水槽に代わる機能を果たし、受水槽の修理が完了すれば、短時間に解体・撤去することが必要である。仮設受水槽の利用は、組立から撤去まで円滑に作業して、初めて可能となるものである。仮設受水槽を利用する作業手順としたのは、仮設受水槽を設置し、受水槽を修理する期間、仮設受水槽から給水栓へ給水し、受水槽の修理が完了した後、仮設受水槽を解体・撤去するまでを仮設受水槽を利用するとしたためである。なお、受水槽の修理とは、水漏れやワレ部分の補強、張替、パテ塗り、塗装等の作業だけでなく、受水槽内の清掃・消毒等法令にかなった一連の作業をいうものである。 The temporary water receiving tank is assembled in a short time, functions as a substitute for the water receiving tank, and should be disassembled and removed in a short time after the repair of the water receiving tank is completed. The temporary water tank can be used only after smooth work from assembly to removal.
