DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Example:

[0038] It should be noted that: See the attached Figures 1 to 8 , F0 is the throttling switch F0, F1 is the throttling switch F1, F2 is the throttling switch F2, F3 is the throttling switch F3, F4 is the throttling switch F4, F5 is the throttling switch F5, F6 is the throttling switch F6, F7 is the throttling switch F7, f0 is the throttling switch f0, f1 is the throttling switch f1, f2 is the throttling switch f2, f3 is the throttling switch f3, and f is the throttling switch f4.

[0039] The mandatory provisions of GB50242, Code for Acceptance of Construction Quality of Building Water Supply, Drainage and Heating Engineering: "Concealed or buried drainage pipes must be subjected to a water filling test before concealment". According to the mandatory provisions of this code: a water filling test must be carried out for concealed or buried drainage pipes, and the water filling test should be carried out before the drainage pipes are concealed; the drainage riser 1 of high-rise civil buildings generally adopts PVC spiral silencer pipes. When the indoor drainage is designed for same-floor drainage or the drainage pipes are concealed in the ceiling, the water filling test should be carried out in layers; the layered water filling test requires the drainage riser 1 to be sealed in layers. When the drainage riser 1 adopts PVC spiral silencer pipes, due to the special structure of its inner wall, there is a technical problem that the main drainage riser cannot be effectively sealed ("effective sealing" is based on the premise that the plan meets the requirements of relevant specifications and standards).

[0040] The layered water filling test device in the prior art does not meet the requirement of "conducting a water filling test before concealing the drainage pipe", and according to the construction industry standard "Technical Code for Construction Drainage Plastic Pipe Engineering" (CJJ / T29-2010) Article 5.3.1 on the drainage pipe installation process: "The pipe installation process should be carried out from bottom to top, first install the vertical pipe, then install the horizontal pipe, and the construction should be continuous." However, the prior art has the problem of "installing the drainage vertical pipe 1 from top to bottom, layer by layer", that is, after installing one layer, a water filling test is carried out on that layer, and the construction of the next layer of pipes is carried out after the test is passed, which is undoubtedly not in line with the construction specifications.

[0041] Therefore, the limitations of the existing technology are:

[0042] 1. The water filling test can only be carried out alternately with the drainage pipe installation during the drainage pipe installation process; when the drainage pipe is installed and before it is delivered for fine decoration (that is, before the drainage pipe installed in the bathroom floor or in the ceiling is concealed), it is impossible to seal the installed drainage riser 1, and there will be a problem that the water filling test cannot be carried out according to the construction acceptance specifications and construction procedures, resulting in substantial obstacles to its application in actual construction.

[0043] 2. The existing drainage pipes are installed "from top to bottom, layer by layer". The water filling test and the drainage pipe installation are carried out alternately "from top to bottom" layer by layer, resulting in the pipe installation not being able to be carried out continuously. This cannot meet the requirements of the industry technical standard (CJJ / T29-2010) that "the pipe installation process should be carried out from bottom to top, first install the vertical pipe, then install the horizontal pipe, and should be constructed continuously."

[0044] 3. Since the inner wall of the PVC spiral silencer has a special structure of spiral raised ribs, the existing general rubber airbag cannot seal the inner wall of the drainage pipe tightly, that is, it cannot effectively seal the drainage riser 1, so the water filling test cannot be carried out.

[0045] Therefore, the solution of this embodiment is proposed as follows:

[0046] See also Figure 1 , 2 7. A water-saving stratified irrigation test device comprises a drainage riser 1 and an airbag assembly for stratified sealing of the drainage riser 1, wherein the airbag assembly comprises: an airbag, wherein the outer surface of the airbag is sleeved with a sleeve; the airbag can be expanded by inflation to squeeze and deform the sleeve, so that the outer surface of the sleeve is closely fitted to the inner wall of the drainage riser 1 to achieve sealing; the airbag assembly can be placed in the drainage riser 1, and each of the airbags is respectively arranged in the sealing section 5 of the drainage riser 1 at each floor 2; and a temporary cover assembly 7 can be used to inflate and exhaust the airbags, and an inspection port is arranged on the drainage riser 1, and the temporary cover assembly 7 can inflate or exhaust the airbags on the current floor and the adjacent floor at the inspection port.

[0047] This embodiment adopts the method of placing the airbag assembly into the installed drainage riser 1 to perform layered plugging. Specifically, the airbag assembly can be Figure 7 The airbag assembly is connected in the manner shown, and then the airbag assembly is placed into the drainage riser 1 from the top, and each airbag of the airbag assembly is located at the position of the drainage riser 1 that needs to be blocked, and each airbag is sleeved with a sleeve, which can be a rubber-plastic tube shell 11. When the airbag is inflated, the airbag expands and squeezes the sleeve sleeved on the outer surface of the airbag. The sleeve has elasticity, and the airbag expands and transmits pressure to squeeze the rubber-plastic tube shell 11, so that the rubber-plastic tube shell 11 is squeezed and filled into the gap part (inner corner) of the special structure of the inner wall of the PVC spiral silencer; solution The problem is that the rubber airbag is directly used in the prior art. When the drainage riser 1 is a PVC spiral silencer pipe, the rubber airbag cannot fit tightly with the inner wall of the PVC spiral silencer pipe after being inflated, and cannot meet the effective sealing requirement in the water filling test. The airbag in this embodiment is made of latex material and has good elasticity. The rubber-plastic pipe shell 11 has a hydrophobic effect and has strong plasticity when squeezed by external force. Those skilled in the art should know that the material of the airbag and the material and shape of the rubber-plastic pipe shell 11 are not limited to the one proposed in this embodiment, as long as the effect to be achieved in this embodiment can be achieved.

[0048] In addition, in this embodiment, the airbag assembly is directly placed into the drainage riser 1, and the airbag is inflated and exhausted respectively. The test steps of this embodiment are to first install the drainage riser 1 and branch pipe 3 of each floor, and then perform layered water filling test layer by layer. In the prior art, it is necessary to install a layer of drainage riser 1 and branch pipe 3, and immediately perform water filling test on the branch pipe 3 of this layer. Only after passing the test can the installation of the drainage riser 1 and branch pipe 3 of the next layer be performed. This method does not meet the construction specifications and will cause substantial obstacles. In addition, the test water of the branch pipe 3 cannot be reused, resulting in excessive amount of test water, which causes waste. In this embodiment, since the drainage riser 1 of each floor is installed before the water filling test, the test water of the branch pipe 3 of the upper floor can flow to the branch pipe 32 of the second floor, and only a small amount of water is needed to perform the second water filling test. Therefore, the use of the airbag assembly can save test water and meet the requirements of continuous construction.
