DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

One end of the drainage pipe 2 extends into the water collection well 1, and the other end extends out of the revetment pit. The pump 3 is connected to the drainage pipe 2 to discharge the water in the water collection well 1 out of the revetment pit. The first waterproof layer 4 is laid on the slope inside the revetment pit, and the second waterproof layer 5 is laid on the embankment slope outside the revetment pit, so as to prevent rainwater from seeping into the embankment and causing bank collapse.

[0031] In this embodiment, the first waterproof layer 4 and the second waterproof layer 5 are both made of waterproof rolls, and specifically, the waterproof rolls can be waterproof cloth, waterproof membrane, etc., preferably lightweight plastic cloth or plastic membrane. A first reel 6 and a second reel 7 for rolling up the first waterproof layer 4 and the second waterproof layer 5 are provided on the top of the revetment foundation pit, and one end of the first waterproof layer 4 and the second waterproof layer 5 are fixed to the first reel 6 and the second reel 7, respectively, and the first waterproof layer 4 and the second waterproof layer 5 are respectively wound on the first reel 6 and the second reel 7 for rolling up.

[0032] In this embodiment, a driving mechanism for driving the first reel 6 and the second reel 7 to reel in and release the first waterproof layer 4 and the second waterproof layer 5 is also provided at the top of the revetment pit. The driving mechanism includes a driving motor 8 installed at the top of the revetment pit. The first reel 6 and the second reel 7 are respectively provided with a first rotating shaft and a second rotating shaft. The output shaft of the driving motor 8 is connected to the first rotating shaft or the second rotating shaft. Pulleys 9 are provided on the first rotating shaft and the second rotating shaft, and the two pulleys 9 are connected by a transmission belt 10. The first waterproof layer 4 and the second waterproof layer 5 are wound on the first reel 6 and the second reel 7 in the same direction, for example, the winding directions are both clockwise or both counterclockwise.

[0033] In this embodiment, a counterweight 11 is provided at one end of the first waterproof layer 4 and the second waterproof layer 5 away from the first reel 6 and the second reel 7. Specifically, the counterweights 11 of the first reel 6 and the second reel 7 are all counterweight blocks, and a plurality of counterweight blocks are provided at equal intervals. By providing the counterweight 11 at one end of the first waterproof layer 4 and the second waterproof layer 5 away from the first reel 6 and the second reel 7, the first waterproof layer 4 and the second waterproof layer 5 can be laid flat on the slope, and when the first waterproof layer 4 and the second waterproof layer 5 are made of a light plastic film, the plastic film can be effectively prevented from being blown up.

[0034] In this embodiment, a waterproof geotextile 12 is laid in the water collection well 1, and a first filter plate 13 is installed around the outer side of the top of the water collection well 1. The first filter plate 13 is vertically arranged and circumferentially closed. A second filter plate 14 is horizontally arranged in the water collection well 1, and the second filter plate 14 is detachably connected to the first filter plate 13. Specifically, the side of the first filter plate 13 close to the water collection well 1 is spaced from the well wall of the water collection well 1, and a hook 15 is arranged on the side of the first filter plate 13 close to the water collection well 1. The hook 15 is located outside the water collection well 1, so as not to affect the installation of the second filter plate 14. A hanging ring 16 is arranged on the edge of the upper surface of the second filter plate 14. When the second filter plate 14 is installed in the water collection well 1, the hanging ring 16 is hooked on the hook 15. A lifting connector is also arranged on the upper surface of the second filter plate 14. The lifting connector can be a structure such as a lifting ring or a hook, so as to facilitate the installation and removal of the second filter plate 14, facilitate disassembly for cleaning, and prevent the second filter plate 14 from being blocked.

[0035] The first filter plate 13 is directly installed on the outside of the top of the water collection well 1, has the function of primary filtration, and can be cleaned outside the first filter plate 13 without disassembly. Specifically, the first filter plate 13 can be fixed to the bottom of the revetment pit by screws or anchors.

[0036] In this embodiment, the pump 3 is installed on the top of the revetment pit, one end of the drainage pipe 2 is connected to the pump 3, and the other end extends to the bottom of the revetment pit and passes through the first filter plate 13 and the second filter plate 14 in sequence to reach the water collection well 1. The drainage pipe 2 is a hose.

[0037] The working principle of the bank protection foundation pit drainage structure in this embodiment is:

[0038] The water in the revetment pit is collected in the water collection well 1 and discharged through the drainage pipe 2 and the water pump 3. By setting the first waterproof layer 4 on the slope inside the revetment pit and setting the second waterproof layer 5 on the embankment slope outside the revetment pit, it is effectively prevented from rainwater scouring the slope and preventing the embankment from being filled with water and causing bank collapse disasters. The first waterproof layer 4 and the second waterproof layer 5 are both made of waterproof rolls, and the first roll 6 and the second roll 7 are set, and the first roll 6 and the second roll 7 are used to roll up the first waterproof layer 4 and the second waterproof layer 5 respectively, which is convenient for laying and rolling up, so that it can be quickly laid before rainfall and quickly rolled up after rainfall, which is convenient for construction.

[0039] Embodiment 2:

[0040] like Figure 6 , Figure 7 As shown, in the bank protection pit drainage structure in this embodiment, the first waterproof layer 4 and the second waterproof layer 5 are provided with a counterweight 11 at one end away from the first drum 6 and the second drum 7. The counterweight 11 of the first waterproof layer 4 is a counterweight ring, and a plurality of counterweight rings are arranged at equal intervals and sleeved on the drainage pipe 2 at the bottom of the bank protection pit. The counterweight 11 of the second waterproof layer 5 is a counterweight block, and a plurality of counterweight blocks are arranged at equal intervals.

[0041] By configuring the counterweight 11 of the first waterproof layer 4 as a counterweight ring and sleeve-mounting the counterweight ring on the drain pipe 2 , the weight of the counterweight 11 can be effectively reduced.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
