The vertical drainage pipeline is fixedly connected with the horizontal drainage pipeline, the upper end of the horizontal drainage pipeline is larger than the lower end of the vertical drainage pipeline, the bottom of the vertical drainage pipeline is located in the horizontal drainage pipeline, and a circulation opening is formed between the outer circumferential face of the vertical drainage pipeline and the inner circumferential face of the horizontal drainage pipeline. And the lower end part of the horizontal drainage pipeline is hermetically communicated with the upper end part of the collecting pipeline. The same-layer drainage caisson structure comprises a caisson body internally provided with a cavity, the same-layer drainage component is arranged in the middle of the caisson body, and the upper end face of the horizontal drainage pipeline is flush with the bottom face of the cavity. On the basis of the characteristic that water cannot enter the caisson through holes, effective drainage can be conducted once water exists, and therefore the phenomenon that water is collected in the caisson for a long time is avoided.

Description

Technical Field

[0001] The utility model relates to a same-layer drainage component and a same-layer drainage caisson structure, belonging to the technical field of drainage of a building caisson backfill layer. Background Art

[0002] With the continuous standardization of the construction industry, the increasing awareness of home buyers about their property rights, and the increasingly updated construction technology, the current downturn in the construction industry and the continuous vicious competition within the industry have led to increased construction costs, reasonable profits approaching the critical edge, and material suppliers constantly shortchanging them, ultimately leading to a continuous increase in project quality accidents.

[0003] Caisson refers to the process of partially or completely sinking the structural layer of the water-using place to a certain height from the corresponding floor during the main construction, burying the horizontal drainage pipes of the water-using place, and then backfilling with lightweight materials. The structural surface only needs to have a hole for drainage riser. After the decoration is completed, the water will theoretically be discharged through the floor drain, but it is not ruled out that some water will seep into the caisson from the floor tiles. If there is no secondary drainage at the bottom of the caisson, the water in the caisson will accumulate more and more day by day. There are two results of the rising water level: one is that the pressure on the bottom of the box increases, and the bottom of the box that was originally watertight begins to seep water downstairs. The second is that the bottom of the box still does not leak downstairs, but the water level rises, and it crosses the threshold of the water-using place and slowly penetrates into the roots of the walls of each room. In view of the feedback from the production line that the construction cost of drainage on the same floor of residential houses is increasing, the risk of water collection in the caisson being unable to be removed during use is increasing, which affects the comfort of users. Utility Model Content

[0004] The purpose of the utility model is to provide a same-layer drainage component and a same-layer drainage caisson structure in response to the above-mentioned problems. Based on the characteristic of water that "penetrates any hole", once there is water, it can be effectively drained, thereby solving the problem of long-term water collection in the caisson.

[0005] The technical solution adopted by the utility model is as follows:

[0022] The utility model is described in detail below in conjunction with the accompanying drawings.

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] A same-floor drainage component, such as Figure 1 , 2 As shown, a vertical drainage pipe 1, a horizontal drainage pipe 2 and a collecting pipe 3 are arranged in sequence from top to bottom and their openings are all in the up and down directions; the vertical drainage pipe 1 is fixedly connected to the horizontal drainage pipe 2, and the upper end of the horizontal drainage pipe 2 is larger than the lower end of the vertical drainage pipe 1, the bottom of the vertical drainage pipe 1 is located in the horizontal drainage pipe 2, and a flow opening is provided between the outer circumferential surface of the vertical drainage pipe 1 and the inner circumferential surface of the horizontal drainage pipe 2; the lower end of the horizontal drainage pipe 2 is sealed and connected to the upper end of the collecting pipe 3.

[0025] Specifically, from top to bottom, there are the finishing layer, caisson and total drainage. This solution sets the vertical drainage pipe 1, horizontal drainage pipe 2 and collection pipe 3 in order according to these three drainage heights. Among them, the vertical drainage pipe 1 is used to collect the water above the finishing layer from the floor drain downward to the horizontal drainage pipe 2 and then to the collection pipe 3, and the horizontal drainage pipe 2 is used to collect the water at the bottom of the caisson to the collection pipe 3. In addition, this component is an integrated structure, and the vertical drainage pipe 1 and the horizontal drainage pipe 2 are fixedly connected and need to be connected. In addition, the water at the bottom of the caisson must flow out from the upper opening of the horizontal drainage pipe 2, and cannot be blocked by the vertical drainage pipe 1. Therefore, in this solution, the vertical drainage pipe 1 and the horizontal drainage pipe 2 are connected and have a flow port, which can facilitate the drainage of the bottom of the caisson. The water in the horizontal drainage pipe 2 all flows to the collection pipe 3, so a sealed connection is adopted. Furthermore, the bottom of the vertical drainage pipe 1 is located in the horizontal drainage pipe 2, that is, the water outlet of the vertical drainage pipe 1 is located below the water inlet connected to the horizontal drainage pipe 2 and above the collecting pipe 3. The vertical drainage pipe 1 does not pass through the caisson when it is discharged, and will not cause water accumulation in the caisson. The upper end of the horizontal drainage pipe 2 is larger than the lower end of the vertical drainage pipe 1, so that there is a gap between the horizontal drainage pipe 2 and the vertical drainage pipe 1 on the horizontal plane, which is convenient for discharge and solves the problem of long-term water accumulation in the sinking structure that cannot be discharged.

[0026] As another specific embodiment, the vertical drainage pipe 1, the horizontal drainage pipe 2 and the collecting pipe 3 are coaxial. This can reduce the water flow resistance, so that the sewage can flow more smoothly. In addition, the water flow smoothly transitions between the pipes, and the pressure distribution is more uniform, which reduces the problems of water leakage and odor caused by pressure imbalance.

[0027] As another specific embodiment, the vertical drainage pipe 1 and the collecting pipe 3 have the same diameter, and the upper end of the horizontal drainage pipe 2 has a larger diameter than the lower end. Since the drainage pipes in the house are usually of the same diameter, the vertical drainage pipe 1 and the collecting pipe 3 have the same diameter and can be used in conjunction with the existing drainage pipes, while the upper end of the horizontal drainage pipe 2 needs to be larger than the vertical drainage pipe 1, and the lower end is connected to the collecting pipe 3, so the upper end of the horizontal drainage pipe 2 has a larger diameter than the lower end.

[0028] As another specific embodiment, the horizontal drainage pipe 2 has a uniform diameter-changing section. The uniform diameter-changing section can reduce pressure fluctuations caused by flow velocity changes, thereby maintaining pressure balance of the system.

[0029] As another specific embodiment, at least two connection blocks 4 are provided between the vertical drainage pipe 1 and the horizontal drainage pipe 2. The connection blocks 4 are provided between the outer circumference of the vertical drainage pipe 1 and the inner circumference of the horizontal drainage pipe 2, and the connection blocks 4 are distributed at intervals along the circumference. The connection blocks 4 provided at intervals not only realize the connection between the vertical drainage pipe 1 and the horizontal drainage pipe 2, but also the interval positions can be used as flow ports to realize the discharge of water from the bottom of the caisson.

[0030] As another specific implementation, the top of the horizontal drainage pipe 2 is provided with an external flange 5. The flange can bear the pressure and weight in the sewer pipe system and disperse these forces to the bottom of the caisson to ensure the stability and safety of the system.

[0031] A same-level drainage caisson structure, such as Figure 3 As shown, it includes a caisson body 6 with a chamber inside, the middle part of the caisson body 6 is provided with the same-layer drainage member as described above, and the upper end surface of the horizontal drainage pipe 2 is flush with the bottom surface of the chamber. It can ensure that the accumulated water in the caisson body 6 can flow out along the upper end surface of the horizontal drainage pipe 2. Furthermore, the horizontal drainage pipe 2 is located at the junction of the structural floor.

[0032] As another specific embodiment, the bottom surface of the chamber has a slope that descends toward the drainage member at the same level, ensuring that the accumulated water in the caisson body 6 can naturally flow to the drainage port and then be discharged outside the caisson. Furthermore, the slope is not less than 1.5%.

[0033] As another specific embodiment, a mounting hole 9 is provided in the middle of the caisson body 6, the horizontal drainage pipe 2 is located in the mounting hole 9, and concrete 7 is poured between the horizontal drainage pipe 2 and the mounting hole 9. It is convenient to install and fix the drainage components on the same layer. Further, the mounting hole 9 is poured with fine stone concrete 7 not less than C20, and the concrete 7 should be about 20-30mm lower than the structural surface layer during pouring to form a groove shape.

[0034] As another specific embodiment, the upper surface of the concrete 7 is lower than the bottom surface of the chamber, and a waterproof layer 8 is provided between the upper surface of the concrete 7 and the bottom surface of the chamber. This can effectively prevent water from leaking from the gaps around the drain and avoid damaging the interior decoration. In addition, in combination with the concrete 7, the waterproof layer 8 is only provided on the upper part. When the self-compacting state of the structural concrete 7 is good, the use of the self-waterproofing of the concrete 7 can save the construction of the waterproof layer 8 on the structure. Furthermore, the waterproof layer 8 can be made of ointment and plugging agent.

[0035] The utility model proposes a same-layer drainage caisson structure, and its construction process is as follows:

[0036] 1. Caisson structure design: According to the characteristics of the project, the engineering design personnel shall design the structural leveling of the caisson parts that need to be drained later. The slope of the designed structural leveling should not be less than 1.5%. Since leveling is required when pouring concrete, the concrete protective layer will exceed the specification requirements. When designing the structure, the upper steel bars of the floor slab should be designed to have the same leveling slope to avoid excessive thickness of the concrete protective layer due to concrete leveling. At the same time, the purpose and requirements of this practice should be specifically stated in the design description.

[0037] 2. After the design drawings are completed, they should be approved by the construction unit, and the on-site operators should be informed one by one, and the structure should be implemented. At the same time, the purchase of pipe joints of this specification and other auxiliary materials should be started.

[0038] 3. When installing risers, a hanging line should be laid from the top floor to the first floor to avoid the risers being not installed firmly enough due to not being on the same vertical line.

[0039] 4. When pouring holes in concrete floor slabs, fine stone concrete with a strength grade greater than or equal to C20 must be used for pouring. During the pouring process, the concrete should be vibrated and compacted. At the same time, the concrete should be 20-30mm lower than the pipe section to form a groove and maintain the concrete.

[0040] 5. After the concrete strength reaches the design strength, use plugging agent or ointment to fill it to the top of the pipe joint.

[0041] 6. After the detailed processing is completed, the construction shall be carried out in accordance with the requirements of the building structure design. During the construction process, it is strictly forbidden to use construction slag as the backfill material in the caisson. Lightweight materials with good permeability and high strength (the strength should not be lower than the M5 mortar strength grade) must be used as the backfill material in the caisson.

[0042] 7. The installation of risers and pipe joints shall meet the technical requirements of 14S307 "Installation of Residential Kitchen and Bathroom Water Supply and Drainage Pipes", the concrete construction shall meet the relevant requirements of GB50204 "Concrete Structure Engineering Construction Quality Acceptance Code", and the waterproofing construction shall meet the relevant requirements of JGJ298 "Residential Indoor Waterproofing Engineering Technical Code".

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The present invention is extended to any new features or any new combination disclosed in this specification, and any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.

[0044] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like 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 directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.
