Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a ramp drainage system leading to a basement. Background Art

[0002] According to relevant specifications, a lower intercepting ditch is usually set at the lower end of the car ramp leading to the underground, and when the car ramp also has an open section without rain shelter facilities, an upper intercepting ditch serving the open section needs to be added at the lower part of the car ramp. In this way, corresponding drainage measures need to be set up for the upper and lower drainage ditches.

[0003] When the underground garage has more than two floors and the second underground floor is a civil air defense basement, the regulations require that "pipelines unrelated to civil air defense shall not be allowed to penetrate into civil air defense, and rainwater pipes shall not enter air defense basements", and the drainage pipes connected to the upper intercepting ditch can only be laid inside the structural plate and connected to the lower intercepting ditch or the bottom sump near the lower intercepting ditch. However, the initial section of the drainage pipe pre-buried in the structure needs to be laid along the bottom of the open section of the intercepting ditch. The diameter of the pre-buried drainage pipe is generally 150mm, and the thickness of the ramp structural plate is generally 250mm~300mm. The size of the pre-buried drainage pipe is too large relative to the structural plate, which increases the difficulty of construction.

[0004] Another solution is to connect the drainage pipe connected to the upper intercepting ditch directly to the sump added near the upper intercepting ditch. However, there are many problems with the setting of the additional sump. (1) If there is no basement on the side of the ramp, the newly added sump is equivalent to a separately added outdoor concrete sewage well, which increases the civil construction cost. (2) If there is a basement on the side of the ramp, the newly added sump is set on one side of the basement, which will occupy the basement area and affect the basement layout. (3) If the second underground floor is a civil air defense basement and the upper intercepting ditch is above the civil air defense basement, the newly added sump will be hung on the top plate of the civil air defense basement or directly set on the ground in the civil air defense basement, which will have a great impact on the use of the civil air defense basement.

DETAILED DESCRIPTION

[0034] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0035] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0036] See also Figures 1 to 7 , the utility model provides a ramp drainage system leading to the basement, please refer to Figure 1, the ramp is a car ramp leading to the first floor of a multi-layered basement. In this embodiment, the second floor of the basement is a civil air defense basement. Further, the ramp drainage system includes a ramp body 100, a first intercepting ditch 41, a second intercepting ditch 42, a sump 40 and a finished drainage ditch 30. Specifically, the ramp body 100 includes a first ramp bottom plate 10 and a second ramp bottom plate 20 extending in sequence along the longitudinal direction, the first ramp bottom plate 10 and the second ramp bottom plate 20 extending obliquely from top to bottom along the longitudinal direction, wherein the top of the first ramp bottom plate 10 is open, and a shield is provided above the second ramp bottom plate 20. Generally speaking, the shield can be formed by the structural body of the basement or by a rainproof structure provided separately. The first ramp bottom plate 10 and the second ramp bottom plate 20 respectively include a structural layer 11 and a leveling layer 12 provided layer by layer from bottom to top. It should be understood that the structural layer 11 is the main load-bearing structure of the ramp body 100, which is preferably cast-in-place reinforced concrete, and the leveling layer 12 can be fine stone concrete or the like laid later on the upper side of the structural layer 11, so that the top surface of the ramp body 100 forms a continuous inclined road surface for vehicles to travel and a reasonable drainage slope.

[0037] like Figure 2 and Figure 5 As shown, the first intercepting ditch 41 is arranged at the lower end of the first ramp bottom plate 10 or the upper end of the second ramp bottom plate 20 to serve the open area of ​​the ramp body 100 to collect rainwater collected by the first ramp bottom plate 10, wherein the first intercepting ditch 41 is formed by a local depression of the structural layer 11 of the first ramp bottom plate 10 or the second ramp bottom plate 20, that is, a transversely extending groove formed by cast-in-place reinforced concrete during pouring.

[0038] The second intercepting ditch 42 is arranged at the lower end of the second ramp bottom plate 20, and the sump 40 is arranged near the second intercepting ditch 42 for storing rainwater collected by the second intercepting ditch 42. The second intercepting ditch 42 is formed by a local depression of the structural layer 11 of the second ramp bottom plate 20, that is, a transversely extending groove formed by cast-in-place reinforced concrete during pouring.

[0039] In an alternative embodiment, see Figures 2 to 7The inner surface of the first intercepting ditch 41 and / or the second intercepting ditch 42 is smoothed and leveled with waterproof cement mortar 412, and the upper side of the first intercepting ditch 41 is covered with a steel grille cover 50. The upper sides of the two side edges of the first intercepting ditch 41 in the longitudinal direction are respectively pre-embedded with angle steels 411, and the angle steels 411 extend in the transverse direction. The steel grille cover 50 is erected between the two angle steels 411. In this way, the steel grille cover 50 with good durability and fast drainage is used to cover the upper side of the first intercepting ditch 41 and / or the second intercepting ditch 42 to ensure the drainage speed while allowing vehicles to pass normally. The angle steel 411 provided in addition plays a role in reinforcing the edge of the ditch to prevent the bearing structure of the edge of the ditch from being damaged or deformed due to pressure from vehicles after long-term use.

[0040] The finished drainage ditch 30 is used to discharge the accumulated water in the first intercepting ditch 41. The inlet end of the finished drainage ditch 30 is connected to the first intercepting ditch 41. The finished drainage ditch 30 is laid in the longitudinal direction and is arranged above the structural layer 11. That is, the finished drainage ditch 30 will not penetrate the lower side of the structural layer 11, nor does it need to be buried in the structural layer 11. The outlet end of the finished drainage ditch 30 at least extends to the lower end of the second ramp bottom plate 20. Among them, the outlet end of the finished drainage ditch 30 is connected to the second intercepting ditch 42, and the second intercepting ditch 42 is connected to the sump 40. That is to say, the finished drainage ditch 30 extends all the way to connect with the second intercepting ditch 42, so that the first intercepting ditch 41 and the second intercepting ditch 42 share the sump 40 to collect water. Alternatively, the outlet ends of the second intercepting ditch 42 and the finished drainage ditch 30 are respectively connected to the sump 40 , that is, the finished drainage ditch 30 extends to connect with the sump 40 , so that the first intercepting ditch 41 and the second intercepting ditch 42 share the sump 40 to collect water.

[0041] In this embodiment, the finished drainage ditch 30 laid above the structural layer 11 is used to guide the accumulated water in the first intercepting ditch 41 of the open section of the ramp main body 100 to the second intercepting ditch 42 or the sump 40 at the lower end of the ramp main body 100, thereby solving the drainage problem of the open section of the ramp main body 100 without rain shelter facilities, and there is no need to pre-bury pipes in or under the structural plate and to set up a separate sump 40. The construction is convenient, the drainage is reliable, and no additional basement area is occupied. When the lower floor is a civil air defense basement, there is no finished drainage ditch at the ramp to penetrate into the interior of the civil air defense basement. At the same time, it meets the requirements of the specifications, the design is more reasonable, and the project cost is reduced.

[0042] Preferably, the drainage system uses a finished drainage ditch 30 to facilitate laying and construction, and preferably includes a finished resin concrete drainage ditch 31, which has the characteristics of high drainage efficiency, strong load resistance, smooth and impermeable, frost resistance, corrosion resistance, and quick installation. It is particularly suitable for drainage in parking lots, main driving lanes of roads, and heavy truck driving areas.

[0043] For further information, please refer to Figure 1 , Figure 4 and Figure 7 , the structural layer 11 of the first ramp bottom plate 10 and the second ramp bottom plate 20 is concave to form a groove 111 extending in the longitudinal direction, and the finished drainage ditch 30 is at least partially placed in the groove 111 and laid along the groove 111. That is, when the structural layer 11 is cast and formed, a groove 111 extending in the longitudinal direction is formed, and the groove 111 needs to be connected with the first intercepting ditch 41, and it is best that the bottom of the groove 111 is flush with the groove when the first intercepting ditch 41 is formed. The groove 111 is used for laying the finished drainage ditch 30, so that the height of the finished drainage ditch 30 matches the first intercepting ditch 41, and the accumulated water in the first intercepting ditch 41 can be smoothly discharged.

[0044] Preferably, the width of the groove 111 is greater than the outer diameter of the finished drainage ditch 30 in the transverse direction, and a gap is formed between the outer periphery of the finished drainage ditch pipe 30 and the inner wall of the groove 111, and the gap is filled with cement mortar grouting 112. In this way, the error tolerance during installation is increased, and the situation that the finished drainage ditch 30 cannot fit with the inner wall of the groove 111 is avoided. After the finished drainage ditch 30 is laid, cement mortar grouting 112 is used to effectively fix the finished drainage ditch 30.

[0045] Preferably, Figure 1 As shown, the groove 111 extends along one side edge of the ramp body 100 in the lateral direction. In this way, the finished drainage ditch 30 is laid by forming the groove 111 on the side edge of the ramp body 100, which is easy to cast and form, and on the other hand, avoids the finished drainage ditch 30 from being subjected to vehicle driving load, so as to reduce the risk of compression and deformation.

[0046] Best, please continue reading Figure 1 The ramp body 100 has a curved section 21 that bends and extends to one side in the lateral direction, and the groove 111 extends at least along the inner edge of the curved section 21. In this embodiment, the finished drainage ditch 30 is laid on the inner edge of the curved section 21, which can effectively reduce the length of the finished drainage ditch 30, reduce the construction workload and engineering cost.

[0047] This embodiment provides two methods for laying the finished drainage ditch 30. In the first embodiment, refer to Figures 1 to 4, the finished drainage ditch 30 is laid by using the concealed ditch method. Specifically, the upper side of the finished drainage ditch 30 is lower than the top of the groove 111 and is covered under the leveling layer 12. Preferably, the finished drainage ditch 30 includes a resin concrete finished drainage ditch 31 and a sealing cover plate 32 covered thereon. Preferably, the sealing cover plate 32 also adopts a finished resin concrete. In this way, the finished drainage ditch 30 is completely buried under the leveling layer 12, and has the advantage of a smooth and beautiful ramp appearance.

[0048] In the second embodiment, please refer to Figure 1 ,and Figures 5 to 7 , an open ditch method is used to lay the finished drainage ditch 30. The upper side of the finished drainage ditch 30 is higher than the top plate of the groove 111 and is flush with the upper side of the leveling layer 12. Preferably, the finished drainage ditch 30 includes a resin concrete finished drainage ditch 31 and a finished grille cover 33 covered thereon, and the finished grille cover 33 can be a steel grille cover 50. In this way, it is easy to inspect the finished drainage ditch 30 and the drainage is faster.

[0049] Obviously, the above described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, ordinary technicians in this field can make other different forms of changes or modifications without creative work, which should fall within the scope of protection of the utility model.
