Technical Field
[0001] The utility model relates to the technical field of tunnels quickly built with concrete blocks, in particular to a vertical combined seepage pipe suitable for drainage of high wall backs. Background Art
[0002] Backfill and drainage are often necessary for tall walls, such as the tall pile-sheet walls on either side of road expansions, gravity retaining walls with steep slopes, and basement foundation pits in building construction. Typically, backfill drainage for tall outdoor walls is directly discharged through conduits, requiring numerous holes in the wall. This significantly impacts the overall strength and aesthetics of the panel. Furthermore, when conventional seepage pipes are placed vertically, a significant amount of water accumulates inside the lower pipes due to the inflow of seepage water from above, seriously affecting the drainage of the lower backfill area. Utility Model Content
[0003] The purpose of the utility model is to overcome the defects of the prior art and provide a vertical combined seepage pipe suitable for drainage of high wall backs. The drainage pipes are combined and converged into the drainage pipe through a conical drainage plate, so that the seepage water is gathered in the drainage pipe, so that the seepage water can flow downward along the drainage pipe, avoiding the backflow of the seepage water below.
[0004] The technical solution to achieve the above purpose is a vertical combined seepage pipe suitable for drainage of tall wall backs, comprising:
[0005] permeable pipes;
[0006] A plurality of drainage pipes arranged in the permeable pipe and connected end to end;
[0007] a conical drainage plate disposed in the permeable pipe and arranged around the drain pipe, wherein the top of the conical drainage plate is fixed to the inner wall of the permeable pipe and the bottom of the conical drainage plate is disposed close to the outer wall of the drain pipe; and
[0008] A filter plate is arranged above the conical guide plate and sleeved on the drain pipe.
[0009] Furthermore, a plurality of drainage grooves are formed on the outer wall of the drainage pipe, and the drainage grooves are arranged along the extension direction of the drainage pipe.
[0010] Furthermore, the filter plate includes:
[0011] Sleeved on the inner ring of the drain pipe;
[0012] an outer ring attached to the inner wall of the water-permeable pipe; and
[0013] A plurality of connecting rods are arranged at intervals between the inner ring and the outer ring.
[0014] Furthermore, the interval between two adjacent connecting rods is determined according to on-site construction requirements.
[0015] Furthermore, the permeable pipe is composed of a plurality of permeable unit segments, and the length of the permeable unit segments is adapted to the length of the drainage pipe.
[0016] Furthermore, an insertion port is formed on the top of the water permeable unit segment, and the inner diameter of the insertion port is adapted to the outer diameter of the water permeable unit segment.
[0017] Furthermore, the top of the conical guide plate is attached to the bottom of the filter plate.
[0018] Furthermore, a water-permeable hole is formed on the wall of the drainage pipe.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] The drainage pipes are combined and converged into the drainage pipes through conical drainage plates, thereby converging the seepage water and preventing the seepage water from flowing back below. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0028] See Figure 1 and Figure 2A vertical combined seepage pipe suitable for drainage behind tall walls, comprising: a permeable pipe 1, a drainage pipe 2, a conical drainage plate 3 and a filter plate 4; a plurality of drainage pipes 2 are arranged in the permeable pipe 1 and are connected end to end; the conical drainage plate 3 is arranged in the permeable pipe 1 and is arranged in a ring around the drainage pipe 2, the top of the conical drainage plate 3 is fixed to the inner wall of the permeable pipe 1, and the bottom of the conical drainage plate 3 is arranged close to the outer wall of the drainage pipe 2; and the filter plate 4 is arranged above the conical drainage plate 3 and is sleeved on the drainage pipe 2.
[0029] In the present invention, a preferred embodiment is: the drainage pipe 2 is installed in the permeable pipe 1, and the permeable pipe 1 is buried in a tall retaining wall or a basement foundation pit, and a filter layer geobag is set on the outside of the permeable pipe 1 to prevent the soil in the soil layer from blocking the seepage efficiency of the permeable pipe 1. Preferably, another permeable pipe 1 inclined upward can be set on the side of the permeable pipe 1 for connection. The inclined upward permeable pipe 1 is buried in the soil to enhance the seepage efficiency. A crushed stone filter layer is set on the outside of the geotextile to prevent large objects in the soil from entering the permeable pipe 1. The filter plate 4 set in the permeable pipe 1 can prevent large debris from clogging the permeable pipe 1. A drainage ditch 5 is set on the top of the permeable pipe 1 that has been set up, and the drainage ditch 5 is connected to the permeable pipe 1.
[0030] Furthermore, a plurality of drainage grooves are formed on the outer wall of the drain pipe 2, and the drainage grooves are arranged along the extension direction of the drain pipe 2. The drainage grooves can facilitate the rapid flow of water, and preferably, the drainage grooves are gear-shaped.
[0031] Furthermore, the filter plate 4 includes an inner ring that fits over the drain pipe 2; an outer ring that fits against the inner wall of the permeable pipe 1; and a plurality of connecting rods spaced between the inner and outer rings. These connecting rods filter out large debris that enters the permeable pipe 1, preventing it from clogging.
[0032] Furthermore, the interval between two adjacent connecting rods is determined according to on-site construction requirements.
[0033] Furthermore, the permeable pipe 1 is composed of a plurality of permeable unit segments, and the length of the permeable unit segments is adapted to the length of the drainage pipe 2 .
[0034] Furthermore, an insertion port is formed on the top of the water permeable unit segment, and the inner diameter of the insertion port is adapted to the outer diameter of the water permeable unit segment.
[0035] Furthermore, the top of the conical guide plate 3 is attached to the bottom of the filter plate 4 .
[0036] Furthermore, a water-permeable hole is formed on the wall of the drain pipe 2. Through the water-permeable hole, part of the liquid flowing through the surface of the drain pipe 2 can flow into the drain pipe 2, thereby accelerating the circulation of the liquid.
[0037] The following describes the use of the vertical combined seepage pipe of the utility model suitable for drainage of high wall backs.
[0038] The drainage pipe 2 is installed in the permeable pipe 1, and the permeable pipe 1 is buried in a tall retaining wall or a basement foundation pit, and an anti-filter layer geobag is set outside the permeable pipe 1 to prevent the soil in the soil layer from blocking the water seepage efficiency of the permeable pipe 1. Preferably, another permeable pipe 1 inclined upward can be set on the side of the permeable pipe 1 for connection. The inclined upward permeable pipe 1 is buried in the soil to enhance the water seepage efficiency. After the vertical permeable pipe 1 and the inclined permeable pipe 1 are combined, After filling the filter layer with geobags, stack them neatly and densely to ensure that the permeable pipe 1 is wrapped. After stacking to a certain height, backfill the wall accordingly. The backfill height is slightly lower than the position of the seepage pipe and the filter layer.
