Description

多階同心圓式井管裝置Multi-stage concentric circular well pipe device

本發明係一多階同心圓式井管裝置，尤指一種兼具可得到高精確度之地下水分層取樣數據，及鑿井之性價比較高之多階同心圓式井管裝置。 The present invention relates to a multi-stage concentric circular well pipe device, especially a multi-stage concentric circular well pipe device which can obtain high-accuracy groundwater stratified sampling data and high cost performance of well sinking.

環境水質之監測範圍包括：河川、水庫、海域、地下水等等。由於地下水蘊藏於地表以下，參閱第6圖，舉例來說，由地表向地下依序為一第一不透水層ZA、一第一含水層Z1、一第二不透水層ZB、一第二含水層Z2、一第三不透水層ZC及一第三含水層Z3。如此，在地表上並無法直接監測任一含水層內之地下水。傳統之地下水監測作法是先由地面向下鑿井再置入井管，以抽取某一深度含水層處之地下水。假設其中之一井W1之底部開口位置是距地表大約50公尺處之該第二含水層Z2，而另一井W2之底部開口位置是距地表大約80公尺處之該第三含水層Z3。 The monitoring scope of environmental water quality includes: rivers, reservoirs, sea areas, groundwater, etc. Since groundwater is stored below the surface, please refer to Figure 6. For example, from the surface to the ground, there are a first impermeable layer ZA, a first aquifer Z1, a second impermeable layer ZB, and a second aquifer in sequence. Layer Z2, a third impermeable layer ZC and a third aquifer Z3. As such, it is not possible to directly monitor groundwater within any aquifer at the surface. The traditional method of groundwater monitoring is to first drill a well from the ground and then insert a well pipe to extract groundwater from a certain depth of aquifer. Assume that the bottom opening position of one of the wells W1 is the second aquifer Z2 about 50 meters above the surface, and the bottom opening position of the other well W2 is the third aquifer Z3 that is about 80 meters above the surface .

工作人員(例如：研究人員或監測員)即可利用現有之汲水或抽水設備，分別由地表連通至該第二含水層Z2及該第三含水層Z3。而分別取得該第二含水層Z2及該第三含水層Z3之地下水，並進行後續之研究或分析工作。假設某一工廠違法排放污染物至地下大約45公尺處之含水層(污染該第二含水層Z2之地下水)，則抽取該井W1即可得知該第二含水層Z2之地下水已被污染。然而，此種傳統作法之缺點是要監測一個含水層就要鑿一井，鑿井成本高且鑿井用地相對需求大。 Staff (for example, researchers or monitors) can use existing water pumping or pumping equipment to connect from the surface to the second aquifer Z2 and the third aquifer Z3, respectively. And obtain the groundwater of the second aquifer Z2 and the third aquifer Z3 respectively, and carry out the follow-up research or analysis work. Suppose a factory illegally discharges pollutants into an aquifer about 45 meters underground (contaminates the groundwater of the second aquifer Z2), then extracting the well W1 can know that the groundwater of the second aquifer Z2 has been polluted . However, the disadvantage of this traditional method is that a well needs to be drilled to monitor an aquifer, the cost of drilling a well is high, and the land for drilling a well is relatively large.

傳統上還有另一種作法，在此簡稱「單井多管法」，是在一口井中，同時置入多支井管，參閱第7圖，單一口井中裝有七支不同深度之井管，假設其中有三支管之深度為地下60公尺、地下70公尺及地下80公尺(分別標示為第一汲 水深度Q1、第二汲水深度Q2及第三汲水深度Q3)，則可分別抽到這三個深度之含水層內的地下水，其他井管之作業方式依此類推。但，此種傳統作法之缺點是要多個井管均為獨立管線，由地面至最深處均為同一口徑，因此鑽井孔徑大，開鑿成本較高，且多個井管在置入深井時，也可能有歪斜或擠毀之問題。 Traditionally, there is another method, referred to as the "single-well multi-pipe method", which is to place multiple well pipes in one well at the same time. See Figure 7. Seven well pipes of different depths are installed in a single well. Suppose there are three pipes with a depth of 60 meters underground, 70 meters underground and 80 meters underground (respectively marked as the first pipe The water depth Q1, the second water drawing depth Q2 and the third water drawing depth Q3) can be pumped to the groundwater in the aquifers of these three depths respectively, and the operation methods of other well pipes are deduced in the same way. However, the disadvantage of this traditional method is that multiple well pipes are independent pipelines, with the same diameter from the surface to the deepest point, so the drilling hole diameter is large and the excavation cost is high, and when multiple well pipes are placed in a deep well, There may also be problems with skewing or collapsing.

有鑑於此，必須研發出可解決上述習用方法缺點之技術。 In view of this, it is necessary to develop a technology that can solve the above-mentioned shortcomings of the conventional method.

本發明之目的，在於提供一多階同心圓式地下水井管裝置，其兼具可得到高精確度之地下水分層取樣數據，及鑿井之性價比較高等優點。特別是，本發明所欲解決之問題係在改善傳統裝置要監測一個深度的含水層就要鑿一井，鑿井成本高且鑿井用地需求大之缺點。另種「單井多管法」需要多個井管均為獨立管線，單一井管由地面至最深處均為同一口徑，多管導致鑽井口徑大，相對開鑿成本較高，且多支井管在置入同一口井時，也可能發生歪斜或擠毀等問題。 The purpose of the present invention is to provide a multi-stage concentric groundwater well pipe device, which has the advantages of obtaining highly accurate groundwater stratified sampling data, and high cost performance of well drilling. In particular, the problem to be solved by the present invention is to improve the shortcomings of the conventional device, which requires drilling a well to monitor a deep aquifer, high cost of well drilling and large demand for well drilling land. Another "single-well multi-pipe method" requires multiple well pipes to be independent pipelines, and a single well pipe has the same diameter from the surface to the deepest point. Multiple pipes lead to large drilling diameter, relatively high drilling cost, and multiple well pipes Problems such as skewing or collapsing can also occur when the same well is placed.

Section 20 (see Figures 3B, 3C, 3D, 3E, 3F and 3G). The central length LA is greater than the first ring length LB; the first ring outer diameter D2 is greater than the central outer diameter D1.

藉此，以該中央圓管部10及該第一同心環狀部20之同心圓結構，達成最低裝設成本之多階同心圓式地下水抽取管裝置；其中，當該中央圓管部10埋設於地下時，該複數個第一間隔部20B係呈垂直狀且為環狀排列，且其所分隔出該複數個第一環通道21係呈垂直狀且為環狀排列。 Thereby, with the concentric structure of the central cylindrical portion 10 and the first concentric annular portion 20, a multi-stage concentric groundwater extraction pipe device with the lowest installation cost is achieved; wherein, when the central cylindrical portion 10 is buried When underground, the plurality of first partitions 20B are vertical and annularly arranged, and the plurality of first annular channels 21 separated by them are vertical and annularly arranged.

In addition, the plurality of elongated hole structures can be obtained by sawing with a common saw. On the one hand, it is easy to process, and on the other hand, the plurality of elongated hole structures also have excellent mud blocking effect.

參閱第4、第5A、第5B及第5C圖，係本發明之第四實施例，其與第一(第二)實施例之差異處，係在於又包括：一第二同心環狀部30，係一體的環繞設置於該第一同心環狀部20外緣，該第二同心環狀部30係具有一第二環頂部開口30A、複數第二間隔部30B、一第二環管長度LC及一第二環外徑D3。該第二環頂部開口30A係鄰近該第一環頂部開口20A，該複數第二間隔部30B係沿該第一同心環狀部20外緣分隔出複數個第二環通道31。該每一第二環通道31係具有一第二環管取樣開口311，該每一第二環取樣開口311係根據預先檢測之含水層所在位置，依序開設於該第二同心環狀部30。該第一環管長度LB係大於該第二環管長度LC；該第二環外徑D2係大於該第一環外徑D1。 Referring to Figures 4, 5A, 5B and 5C, which are the fourth embodiment of the present invention, the difference from the first (second) embodiment is that it further includes: a second concentric annular portion 30 , which are integrally arranged around the outer edge of the first concentric annular portion 20, and the second concentric annular portion 30 has a second ring top opening 30A, a plurality of second spacers 30B, and a second ring pipe length LC and a second ring outer diameter D3. The second ring top opening 30A is adjacent to the first ring top opening 20A, and the plurality of second spacers 30B separates a plurality of second ring channels 31 along the outer edge of the first concentric annular portion 20 . Each second ring channel 31 has a second ring pipe sampling opening 311 , and each second ring sampling opening 311 is opened in sequence in the second concentric annular portion 30 according to the position of the aquifer detected in advance. . The first ring length LB is greater than the second ring length LC; the second ring outer diameter D2 is greater than the first ring outer diameter D1.

本發明可包括複數抽水馬達40，係對應該中央取樣開口13、該第一環管取樣開口211及該第二環管取樣開口311，而分別設於相對應之該中央通道13、該第一環通道21與該第二環通道31內。 The present invention may include a plurality of pumping motors 40, which correspond to the central sampling opening 13, the first loop sampling opening 211 and the second loop sampling opening 311, and are respectively disposed in the corresponding central channel 13, the first loop sampling opening 13 and the first loop sampling opening 311. Inside the ring channel 21 and the second ring channel 31 .

本發明主要應用於抽取不同深度之地下水(亦即分層取樣)，以進行環境水質之監測及其他抽水試驗。欲達成汲取不同深度之地下水，就必需從地面向地下鑿井，再置入井管以抽取某一深度之地下水。亦即，每鑿一井置入一井管，只用以抽取相對應深度之地下水。如此，欲汲取N個深度之地下水，便需鑿N個井，其成本相當高。當然，雖可加大鑿井之孔徑，再置入複數支不同長度之井管，利用單井抽取不同深度之分層地下水，但是，勢必要加大鑿井之孔徑，同樣也會提高成本。 The present invention is mainly applied to extract groundwater at different depths (ie, stratified sampling) for monitoring environmental water quality and other pumping tests. In order to extract groundwater of different depths, it is necessary to dig a well from the ground to the ground, and then insert a well pipe to extract groundwater at a certain depth. That is, a well pipe is inserted into each well, which is only used to extract groundwater at the corresponding depth. In this way, in order to extract the groundwater of N depths, it is necessary to drill N wells, and the cost is quite high. Of course, although it is possible to increase the hole diameter of the sinking well, and then insert multiple well pipes of different lengths, and use a single well to extract stratified groundwater of different depths, but it is necessary to increase the diameter of the sinking well, which will also increase the cost.

本發明針對這個部分，將該中央圓管部10及該第一同心環狀部20設計為多階同心圓式的改良裝置，該第一同心環狀部20之該第一環外徑D2係大於該中央圓管部10之該中央外徑D1，使該第一同心環狀部20可以同心圓式套設於該中央圓管部10外側，且該中央圓管部10之該中央長度LA係大於該第一同心環狀部20之該第一環管長度LB。該第一同心環狀部20係具有複數(6)個第一環通道21，相對應具有複數(6)個(參閱第3B、第3C、第3D、第3E、第3F及第3G圖)該第一環管取樣開口211(如第1B圖所示，分別位於一第一深度L1、一第二深度L2、一第三深度L3、一第四深度L4、一第五深度L5及一第六深度L6)。亦即，只要鑽鑿孔徑接近該第一同心環狀部20之該第一環外徑D2範圍內之井。即可汲取9個不同深度之分層地下水。 Aiming at this part, the present invention designs the central cylindrical portion 10 and the first concentric annular portion 20 as a multi-stage concentric improved device, and the first ring outer diameter D2 of the first concentric annular portion 20 is Greater than the central outer diameter D1 of the central cylindrical portion 10, so that the first concentric annular portion 20 can be concentrically sleeved on the outside of the central cylindrical portion 10, and the central length LA of the central cylindrical portion 10 is greater than the first loop length LB of the first concentric annular portion 20 . The first concentric annular portion 20 has a plurality of (6) first annular channels 21 corresponding to a plurality of (6) (refer to Figures 3B, 3C, 3D, 3E, 3F and 3G) The first loop sampling opening 211 (as shown in FIG. 1B , is located at a first depth L1 , a second depth L2 , a third depth L3 , a fourth depth L4 , a fifth depth L5 and a first depth L5 , respectively). Six depth L6). That is, as long as the hole diameter is close to the well within the range of the outer diameter D2 of the first ring of the first concentric annular portion 20 . It can draw stratified groundwater at 9 different depths.

同理，如第4、第5A、第5B及第5C圖所示，只要再套設該第二同心環狀部30(鑿井之孔徑只要略加大)，即可抽取25個不同深度之地下水，數量超過3倍，但相對於其它傳統方法而言，鑿井費用可能幾乎不用增加，卻事半功倍。 Similarly, as shown in Figs. 4, 5A, 5B, and 5C, as long as the second concentric annular portion 30 is set (the hole diameter of the well is only slightly enlarged), 25 different depths can be extracted. Groundwater, the amount is more than 3 times, but compared with other traditional methods, the cost of drilling wells may hardly increase, but with half the effort.

此外，以上之實施例只提到第二同心環狀部30，當然，依此多階同心圓之原理，本案也可再包括第三同心環狀部(圖中為未示)或更多同心環狀部(圖中為未示)，均為本案之保護範圍。 In addition, the above embodiment only mentions the second concentric annular portion 30. Of course, according to the principle of multi-order concentric circles, the present case can also include a third concentric annular portion (not shown in the figure) or more concentric annular portions. The annular part (not shown in the figure) is the protection scope of this case.

本發明之優點及功效係如下所述： The advantages and effects of the present invention are as follows:

[1]可得到高精確度之地下水分層取樣數據。由於本案是單一管中具有多個間隔之獨立通道(包括複數第一環通道及複數第二環通道)，分別對應不同深度含水層之取樣開口(包括中央取樣開口、複數第一環管取樣開口及複數第二環取樣開口)，所取之地下水樣均為特定之含水層深度，不會彼此污染。故，可得到高精確度之地下水分層取樣數據。 [1] Highly accurate groundwater stratified sampling data can be obtained. Since this case is an independent channel with multiple intervals in a single pipe (including a plurality of first ring channels and a plurality of second ring channels), the sampling openings (including the central sampling opening and the plurality of first ring pipe sampling openings) corresponding to different depths of aquifers are respectively and multiple second ring sampling openings), the groundwater samples taken are of specific aquifer depths and will not contaminate each other. Therefore, highly accurate groundwater stratified sampling data can be obtained.

[2]鑿井之性價比(CP值)較高。由於本案為多階同心圓式井管裝置，中央圓管部之管較長，外圍部分(例如第一同心環狀部)之管較短，兩者為同軸心。換言 之，在包括孔徑與深度之總鑿井成本上，可比公知裝置之CP值較高。故，鑿井之性價比較高。 [2] The cost performance (CP value) of well sinking is relatively high. Since this case is a multi-stage concentric circular well pipe device, the pipe in the central circular pipe portion is longer, and the pipe in the peripheral portion (eg, the first concentric annular portion) is shorter, and the two are concentric. In other words In addition, in terms of total sinking cost including hole diameter and depth, the CP value of the conventional device is higher. Therefore, the cost performance of well drilling is relatively high.

以上僅是藉由較佳實施例詳細說明本發明，對於該實施例所做的任何簡單修改與變化，皆不脫離本發明之精神與範圍。 The above is only to describe the present invention in detail by means of preferred embodiments, and any simple modifications and changes made to the embodiments do not depart from the spirit and scope of the present invention.
