New description: [New technical field] The new type is related to a tester, especially a concrete permeability tester. [Prior Art] Nowadays, in the roadside slope retaining facilities or hillsides, etc., in order to meet the engineering needs, it is often necessary to lay concrete. In order to balance ecological considerations, these paved concretes must have certain Water permeability, so that the water can be smoothly infiltrated or discharged. However, at present, there is only a complete set of testers specially used for testing soil water permeability, and there is no complete tester for testing the permeability of concrete. · [New content] Therefore, the purpose of the present invention is to provide a concrete permeability tester capable of testing the permeability of concrete. Therefore, the novel concrete permeability tester comprises a base, a lower official member, an upper tubular member, and an outer sleeve. The base has a bottom wall, a peripheral wall disposed on the bottom wall, a sump defined by the bottom wall and the peripheral wall, a lower water pipe disposed on the peripheral wall and communicating with the sump, and at least a padding element disposed on the bottom wall and located in the sump. The lower tubular member is disposed on the base, the lower tubular member has a first upper open end, and a first open end, the first lower open end abuts against the height member and is spaced apart from the bottom wall. The upper pipe member is disposed on the lower pipe member, the upper pipe member has a pipe wall surrounding a water inlet hole, and an upper water pipe disposed on the camp wall and communicating with the water inlet hole, the pipe wall having a second pipe An upper open end and a second lower open end that abuts the first upper open end. The outer sleeve is sleeved between the upper and lower tubular members and surrounds the first upper open end and the second lower open end. The outer sleeve has a lower height than the upper outlet pipe. The above and other technical contents, features and effects of the present invention will become apparent from the following detailed description of the preferred embodiments of the invention. Referring to Figures 1 and 2, a preferred embodiment of the concrete permeable tester comprises a base 1 一下, a lower tubular member 2〇, an upper tubular member 30, and an outer sleeve 4〇. The base 10 has a bottom wall u, a peripheral wall 12 disposed on the bottom wall n, a sump η defined by the bottom wall U and the peripheral wall 12, a sump η disposed on the peripheral wall 12 and the sump 13 The connected lower outlet pipe 14, and the second height member 15 detachably disposed on the bottom wall U. In this embodiment, the lower outlet pipe 14 of the base 1 is adjacent to the top edge of the peripheral wall 12, and the pad elements 15 are padded blocks. Further, it can be understood that the pad elements 15 can also be solid. The lower tubular member 20 is disposed at the predetermined position of the bottom wall u, and the lower tubular member 20 has a first upper open end 21 and a first lower open end 22, the first lower open end 22 It abuts against the pad elements 15 and is spaced apart from the bottom wall u. In the present embodiment, the lower tube member 20 is made of PVC. The upper pipe member 30 is disposed on the lower pipe member 2'', and the upper pipe member 3b has a pipe wall 31' surrounding a water inlet hole 33 and a pipe wall 31 disposed on the pipe wall 31 and communicating with the water inlet hole 33 of the M443166. The outlet pipe 32, the "Η _ open end 311, and - and the first upper open end _ ^ end 312. Docked brothers open the opening in this embodiment, the upper pipe G is made of PVC. A head difference between the water pipe 32 and the lower outlet pipe 14 is further h. The water jacket 32 is watertightly nested between the upper and lower pipe members 3〇, 2〇, and the first around the first pipe. The open end 21 盥 ^ ^ 40 ^ x the open end 312, the outer sleeve 40 is lower than the upper outlet pipe 32. The outer sleeve 40 prevents water from seeping between the second lower open end 312 The first open end 21 and the first in the present embodiment, the outer sleeve 40 is made of Pvc. _ Secondly, as shown in FIG. 3, when the present invention is to be used for a concrete soil test, the soil is water-repellent. In the test, the concrete test body 100 is first solidified in the lower pipe member 20, and then the new assembly is inserted into the book, wherein the concrete body type 1 〇0 has a length. L, a diameter D, and Δ7 In this embodiment, L=2D. Straight U and a cross-sectional area A, at the time of / (4) inspection, the water flow can be poured from the water inlet hole 33 of the upper pipe member 30. 1 let the water flow through the concrete test body 10 (10) flow the sump 13 & 'the drain pipe 14 from the lower outlet pipe 14 to the inside of the container 200' in this process ^ 'excessive water flow will The upper outlet pipe 32 is drained, so after the test water permeable time t, the water pipe can be measured from the lower outlet pipe to the heart thief 2 () () _ - total water permeability Q, according to the following penetration The coefficient 17 can be used to check the water permeability of the concrete sample 100: the permeability coefficient κ = hAt 5 , wherein the larger the permeability coefficient K, the better the water permeability of the concrete sample 1 经由. The description of the present invention can be summarized as follows: 1. The present invention provides a complete set of tester which can be used for testing the permeability of concrete, which can facilitate the user to conveniently test the water permeability of the concrete sample 100. The material of the new lower pipe member 20 is PV (:, the cost is quite cheap, and the water permeability test of the concrete test body 100 is completed. The lower pipe member 20 can be discarded together with the concrete test piece 1 that has been tested, so that the user does not need to recover the warm soil test sample 100 from the lower pipe #2Q. The lower pipe member 20 is removed; thereafter, if another concrete permeability test is to be carried out, the user only needs to solidify the new concrete test body into another new lower pipe #20, which is convenient for another In one test, the concrete permeable tester of the present invention can not only facilitate the test of the water permeability of the concrete test body, but also has a low replacement cost and is economical, so that the purpose of the present invention can be achieved. The above-mentioned ones are only the preferred embodiments of the present invention, and the scope of the present invention cannot be limited thereto, that is, the simple equivalent changes and modifications made by the novel patent application scope and the new description contents. , are still within the scope of this new patent.
