Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building drainage, in particular to a drainage system for a building foundation pit. Background Art
[0002] A renewal project in an urban area had a very narrow construction environment. Surrounding buildings and structures were very close to the construction area, and special care was required during the construction process to avoid impacting these existing structures.
[0003] To prevent deformation or damage to surrounding buildings and structures during construction, deep foundation pit support typically utilizes concrete internal supports. This support structure effectively maintains the stability of the pit and minimizes impact on the surrounding environment. Within the pit, the pump drain pipes and cables for the drainage well are routed along the edges of the pit support structure. This ensures that the pipes and cables do not obstruct construction while also allowing for easy connection to the drainage well.
[0004] However, in order to avoid construction activities on the ground, drainage pipes and cables are usually hung at higher positions, and the pumping operation of the drainage well usually lasts for a long time. During this period, the drainage pipes and cables may be disturbed by various construction activities or affected by strong winds, causing them to shake or even be damaged. Utility Model Content
[0005] In view of this, the utility model provides a drainage system for a construction foundation pit to solve the problem that drainage pipes and cables are affected during construction.
[0006] In a first aspect, the utility model provides a drainage system for a construction foundation pit, the drainage system comprising:
[0007] Multiple concrete supports are set in the foundation pit;
[0008] A sleeve is embedded in each concrete support and passes through both sides of the concrete support;
[0009] A plurality of lattice columns are set up between two adjacent concrete supports, and the two ends of the lattice columns are respectively connected to the sleeves on the two concrete supports; one end of the lattice column at the bottom is connected to the bottom concrete support, and the other end is inserted into the column pile at the bottom of the foundation pit;
[0010] A drainage component, one end of which is connected to the drainage area at the top of the foundation pit, and the other end of which extends from the lattice column through each concrete-supported casing and each lattice column and is inserted into the drainage well.
[0011] Beneficial effects: In the embodiment of the present invention, sleeves are pre-buried at the places where the lattice columns pass through the concrete supports. By inserting the drainage assembly into the cavity in the lattice column and the pre-buried sleeves, and then passing the drainage assembly through the cavity in the lattice column and the pre-buried sleeves, the drainage assembly can be prevented from being disturbed by various construction activities. At the same time, it is also possible to avoid the drainage assembly from passing directly through the underground main structure, thereby reducing interference and damage to the main structure. Furthermore, there is no need to reserve holes separately on the structural floor to arrange the drainage assembly, which can simplify the construction process and reduce additional workload. Since there are no holes reserved on the structural floor, no additional sealing work is required after the drainage well drainage pipe is removed, saving time and cost. In addition, it can also solve the impact of the drainage assembly on the construction progress during the earth excavation and concrete support construction of the internal support support system and the construction of the underground structure. This can ensure the safety and efficiency of operations such as tower crane material lifting.
[0012] In an optional embodiment, the inner diameter of the sleeve at least matches the outer diameter of the drainage component and the number of the drainage components.
[0013] In an optional embodiment, the drainage assembly includes:
[0014] Drain pipes;
[0015] Cables;
[0016] A protective layer is wrapped around the drain pipe and the cable.
[0017] In an optional embodiment, the drainage pipe is a PVC pipe.
[0018] In an optional embodiment, the inner diameter of the PVC pipe adopts a standard pipe diameter of 100 mm.
[0019] In an optional embodiment, from the inside to the outside, the protective layer is composed of rubber, iron wire and tape, and the protective layer wraps the drain pipe.
[0020] Beneficial Effects: This embodiment of the utility model uses a protective layer to wrap the drain pipe, preventing it from falling or abrading when passing through concrete supports, thereby improving its protection. Furthermore, wrapping the drain pipe into a tapered shape using rubber, wire, and tape reduces friction between the pipe and the casing, further protecting it from damage.
[0021] In an optional embodiment, the protective layer wraps the drain pipe into a conical structure.
[0022] In an optional embodiment, the sleeves are arranged in a vertical direction, and the sleeves on each concrete support and the lattice columns are all on an extended line of a straight line.
[0023] In an optional embodiment, the drainage system further includes:
[0024] A drainer is provided on the top outside of the foundation pit; the drainer is connected to the drainage assembly. In an optional embodiment, at least four concrete supports extending in the horizontal direction are provided in the foundation pit, and the four concrete supports are distributed in the vertical direction.

[0035] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0036] A renewal project in an urban area had a very narrow construction environment. Surrounding buildings and structures were very close to the construction area, and special care was required during the construction process to avoid impacting these existing structures.
[0037] To prevent deformation or damage to surrounding buildings and structures during construction, deep foundation pit support typically utilizes concrete internal supports. This support structure effectively maintains the stability of the pit and minimizes impact on the surrounding environment. Within the pit, the pump drain pipes and cables for the drainage well are routed along the edges of the pit support structure. This ensures that the pipes and cables do not obstruct construction while also allowing for easy connection to the drainage well.
[0038] However, in order to avoid construction activities on the ground, drainage pipes and cables are usually hung at higher positions, and the pumping operation of the drainage well usually lasts for a long time. During this period, the drainage pipes and cables may be disturbed by various construction activities or affected by strong winds, causing them to shake or even be damaged.
[0039] In view of this, the utility model provides a drainage system for a construction foundation pit to solve the problem that drainage pipes and cables are affected during construction.
[0040] The following combination Figures 1 to 4 , describing the embodiments of the present utility model.
[0041] According to an embodiment of the present invention, on the one hand, a drainage system for a construction foundation pit is provided, the drainage system comprising a concrete support 1, a sleeve 2, a lattice column 3 and a drainage assembly 4 located in the foundation pit.
[0042] Specifically, in this embodiment, multiple concrete supports 1 are set in the foundation pit. Each concrete support 1 extends in the horizontal direction, and each concrete support 1 is distributed in the vertical direction, such as Figure 2 shown.
[0043] Furthermore, in this embodiment, the sleeve 2 is pre-buried in each concrete support 1 , and the sleeve 2 is also distributed in the vertical direction, so that the sleeve 2 can pass through both sides of each concrete support 1 , that is, through the upper and lower sides of each concrete support 1 .
[0044] Furthermore, in this embodiment, multiple lattice columns 3 are set up between two adjacent concrete supports 1, and the two ends of the lattice columns 3 are respectively connected to the sleeves 2 on the two concrete supports 1. One end of the lattice column 3 at the bottom is connected to the bottom concrete support 1, and the other end is inserted into the column pile 7 at the bottom of the foundation pit.
[0045] Furthermore, in this embodiment, one end of the drainage component 4 is connected to the drainage area at the top of the foundation pit, and the other end of the drainage component 4 extends from the lattice column 3 through the sleeve 2 of each concrete support 1 and each lattice column 3 and is inserted into the drainage well 5.
[0046] With such an arrangement, the embodiment of the utility model pre-buries the sleeve 2 where the lattice column 3 passes through the concrete support 1. By inserting the drainage assembly 4 into the cavity in the lattice column 3 and the pre-buried sleeve 2, and then passing the drainage assembly 4 through the cavity in the lattice column 3 and the pre-buried sleeve 2, the drainage assembly 4 can be prevented from being disturbed by various construction activities. At the same time, it can also avoid the drainage assembly 4 from directly passing through the underground main structure, thereby reducing interference and damage to the main structure. Furthermore, there is no need to reserve holes separately on the structural floor to arrange the drainage assembly 4, which can simplify the construction process and reduce additional workload. Since there are no holes reserved on the structural floor, no additional sealing work is required after the drainage pipe of the drainage well 5 is removed, saving time and cost. In addition, it can also solve the impact of the drainage assembly 4 on the construction progress during the earthwork excavation of the internal support and protection system and the construction of the concrete support 1 and the underground structure. This can ensure the safety and efficiency of operations such as tower crane material lifting.
[0047] Furthermore, in an optional embodiment, the inner diameter of the casing 2 at least matches the outer diameter of the drainage assembly 4 and the number of drainage assemblies 4. In other words, the diameter of the casing 2 embedded in the concrete support 1 should be determined based on the actual diameter of the drainage pipe of the water pump in the drainage well 5. If the diameter of the drainage pipe of the water pump in the drainage well 5 is smaller, the diameter of the embedded casing 2 should also be smaller, and vice versa.
[0048] Furthermore, if multiple drainage pipes are required within the cavity of a lattice column 3, the diameter of the sleeve 2 embedded in the concrete support 1 must take into account the total diameter of all drainage pipes. For example, if there are two or more drainage pipes, each with a diameter of 50 mm, the total sleeve 2 diameter may need to be larger to ensure that all drainage pipes can pass through smoothly.
[0049] Furthermore, in an optional embodiment, the drainage component 4 includes: a drainage pipe, a cable and a protective layer, and the protective layer is wrapped around the drainage pipe and the cable.
[0050] Furthermore, in an optional embodiment, the drain pipe is a PVC pipe. Of course, this embodiment is only an example of the material of the drain pipe, but it is not limited thereto. Those skilled in the art can make changes according to actual conditions as long as they can achieve the same technical effect.
[0051] Furthermore, in an optional embodiment, the inner diameter of the PVC pipe adopts a standard pipe diameter of 100 mm. Of course, this embodiment is only an example of the inner diameter of the PVC pipe, but it is not limited to this. Those skilled in the art can change it according to actual conditions as long as the same technical effect can be achieved.
[0052] Furthermore, in an optional embodiment, from the inside to the outside, the protective layer is composed of rubber, iron wire and tape, and the protective layer wraps the drain pipe.
[0053] Thus, the embodiment of the present invention wraps the drain pipe with a protective layer, preventing it from falling or abrading when passing through the concrete support 1, thereby improving the protection of the drain pipe. Furthermore, wrapping the drain pipe into a tapered shape using rubber, wire, and tape reduces friction between the drain pipe and the sleeve 2, further protecting the drain pipe from damage.
[0054] Furthermore, in an optional embodiment, the protective layer wraps the drain pipe into a conical structure.
[0055] Furthermore, in an optional embodiment, the sleeve 2 is arranged in a vertical direction, and the sleeve 2 on each concrete support 1 and the lattice column 3 are all on an extended line of a straight line.
[0056] Furthermore, in an optional embodiment, the drainage system further includes a drainer 6, which is arranged on the outside of the top of the foundation pit, and the drainer 6 is connected to the drainage assembly 4. The drainer 6 can be a drainage ditch or a drainage pipe arranged on the periphery of the outside of the top of the foundation pit, or other facilities for drainage. Of course, this embodiment is only an example of the type of drainer 6, but it is not limited to this. Those skilled in the art can make changes according to actual conditions as long as they can achieve the same technical effect. Further, in an optional embodiment, at least four concrete supports 1 extending in the horizontal direction are provided in the foundation pit, and the four concrete supports 1 are distributed in the vertical direction.
[0057] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
