Technical Field

[0001] The invention relates to an integrated water-isolating and pumping device for a foundation pit in a water-rich stratum, belonging to the field of water-isolating and pumping devices. Background Art

[0002] A water-rich stratum refers to a stratum with abundant water content in the underground aquifer. A water-rich stratum usually has high permeability and water storage capacity.

The existing water-rich stratum pumping devices still have some shortcomings when used.

[0003] For example, the invention patent with publication number CN113217097A discloses a deep open comprehensive dewatering method and a water pump for a dark-dug tunnel in a water-rich composite stratum, including comprehensive dewatering of the dark-dug tunnel by combining dewatering in the tunnel and dewatering in a dewatering well outside the tunnel; dewatering in the tunnel includes setting a water pump obliquely downward at the bottom of the tunnel, spraying concrete mortar on the face, washing pipes, testing and dewatering; after the dewatering is completed, the various components in the water pump are taken out, and the cavity of the pipe shed is filled tightly; dewatering in the dewatering well The method includes inserting a filling pipe into the drill pipe, and after the hole is drilled to the designed depth, increasing the drilling speed of the drill bit, increasing the pumping power of the filling pipe, pumping out the collapsed mud and sand under the scouring of mud and water, until a hole area is formed at the bottom of the precipitation well, and reducing the rotation speed of the drill bit; inserting a precipitation pipe from the filling pipe, and then lifting the filling pipe while conveying filter material to the bottom of the precipitation well through the filling pipe; precipitation is carried out through the precipitation pipe, which has the advantages of high precipitation efficiency and applicability to precipitation of a variety of composite formations with low permeability and high precipitation difficulty. Although the above-mentioned device can adapt to a variety of composite formations, when in use, the existing pumping device cannot be used in gravel formations, cannot automatically increase its own counterweight while pumping water, and thus penetrate into the gravel formation for continuous pumping, and the existing pumping device cannot adapt to the uneven walls on both sides of the construction pit to achieve the water-isolating function.

[0017] (III) Beneficial effects

[0018] The present invention provides an integrated water-isolating and pumping device for a foundation pit in a water-rich stratum, which has the following beneficial effects:

[0019] 1. Through the provided guide drill and drilling frame, the device can first push the second cylinder and inner cylinder of the porous structure deep into the appropriate position underground before draining water, and then drive the connecting shaft to rotate through the waterproof motor on the driving assembly, and the connecting shaft drives the second gear to rotate, thereby driving the second gear ring and the guide drill to rotate, and the drilling frame outside the guide drill is used to squeeze the gravel in the water-rich stratum, so that the inner cylinder and the second cylinder can be moved to the appropriate position before drilling, which solves the problem that the existing pumping device cannot be used in water-rich strata with more gravel, and the device has the advantage of stronger adaptability.

[0020] 2. The device is provided with a water-proof component, and the second partition in the first partition and the slide plate in the second partition are extended outward by the first elastic band and the second elastic band. The first baffle and the second baffle can protect the elastic band, so that the second cylinder can achieve a water-proof function during the downward drilling process. The first elastic rope can pull multiple stacked slide plates, so that the slide plates can adapt to the uneven walls on both sides of the foundation pit for water-proofing, thereby enhancing the stability of the device and solving the problem that the existing pumping device cannot adapt to the uneven walls on both sides of the construction pit to achieve a water-proofing function.

[0021] 3. By setting the first connecting pipe, the second connecting pipe and the inner plate, external pipes are connected at the positions of the first through hole and the second through hole, so that the device can pump groundwater into the cavity between the first cylinder and the inner plate during the pumping process, thereby automatically increasing the overall counterweight of the device, which is beneficial for drilling down in the gravel formation to carry out drainage work. It can not only improve the overall stability of the device, but also overcome the resistance of the gravel layer, improve the working efficiency of the device, and solve the problem that the existing pumping device cannot automatically increase its own counterweight while pumping water, so as to penetrate into the gravel formation for continuous pumping.

[0022] 4. Through the set driving assembly, when the waterproof motor drives the connecting shaft to rotate, the connecting shaft can transmit torque through the connecting blocks with beveled surfaces on both sides, driving the first gear to rotate, so as to adjust the degree of staggering of the third through hole and the fourth through hole, so as to facilitate the subsequent use of pumping holes of different sizes for pumping water according to different soil layers. When the limit block abuts against the inner wall of the limit groove, the rotation resistance of the connecting shaft is too large, the connecting block shrinks to the inside of the connecting shaft, and the spring is compressed, so that the connecting shaft slides inside the first gear, while the second gear continues to rotate and drives the guide drill to rotate. At this time, the third through hole and the fourth through hole are in a separated state, and the second cylinder and the inner cylinder are closed, so that the pumping structure of the device remains closed during the drilling process to ensure stable pumping in the subsequent process. The device can switch between the two functions of drilling and adjusting the size of the pumping hole through a single driving structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, the water-blocking assembly 3 includes a connecting sleeve 301 slidably installed on the outside of the first cylinder 1 and the convex plate 9, the two sides of the connecting sleeve 301 are fixedly connected with the first partition 302, the second partition 303 is slidably installed in the first partition 302, the bottom of the second partition 303 and the first partition 302 are welded with a fixing block 305, the interior of the second partition 303 is stacked with a plurality of slide plates 304, the slide plate 304 and the second partition 303 are fixedly connected with a first elastic band 306, and the first A second elastic band 307 is fixedly connected between the second partition 303 and the first partition 302.

[0049] Embodiment 3:

[0050] The schemes in Example 1 and Example 2 are further introduced below in combination with specific working methods, as described below:

[0051] Specifically, when the integrated water-proofing and pumping device for foundation pit in water-rich strata is used: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the support assembly 2 cooperates with the convex plate 9 to ensure that the first cylinder 1 is guided, and the third connecting plate 204 can slide inside the first connecting plate 202 through the second connecting plate 203, so as to change the support range of the device according to the size of the foundation pit. Subsequently, the outer sleeve 201 can be kept fixed by connecting anchor rods inside and outside the third connecting plate 204. When used in a large foundation pit, multiple devices can be hoisted into the foundation pit to pump water in different areas. In the regional pumping type, the pumping area can be separated by the water-blocking assembly 3. The first elastic band 306 between the slide plate 304 and the second partition plate 303 can extend the slide plate 304 to the outside of the second partition plate 303, and the second elastic band 307 between the second partition plate 303 and the first partition plate 302 can move the second partition plate 303 to the outside of the first partition plate 302. The second partition plate 303 cooperates with the slide plate 304 to separate the two sides of the foundation pit. The stacked slide plates 304 can keep the adjacent slide plates 304 in close contact with each other, so as to adapt to the subsequent water-proofing work of the foundation pits with different widths and different wall undulations, thereby realizing the function of regional water pumping. When the subsequent device drills downward, the convex plate 9 can make the first cylinder 1 move vertically downward on the outer bushing 201 and the connecting sleeve 301, and the conical structure fixing block 305 can keep the first partition plate 302 and the second partition plate 303 fixed after being placed at the bottom of the foundation pit.

[0052] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the waterproof motor 1702 on the support plate 1701 is used to drive the connection shaft 1703 to rotate. When the connection shaft 1703 rotates, it abuts the connection block 1709 through the inner wall of the groove 1708, thereby driving the first gear 1704 to rotate. When the first gear 1704 rotates, it drives the first gear ring 1705 to rotate. Since the first gear ring 1705 and the inner cylinder 18 are fixedly connected, when the first gear ring 1705 rotates, it drives the inner cylinder 18 to rotate, so that the angle difference between the inner cylinder 18 and the second cylinder body 10 is adjusted, and the degree of staggering between the third through hole 19 on the second cylinder body 10 and the fourth through hole 20 on the inner cylinder 18 will change, so that the device can change the pumping efficiency of the device according to the pumping environment, and thus adapt to different working conditions. The limit block 1706 and the limit groove 1707 can limit the rotation range of the inner cylinder 18. When the limit block 1706 rotates to Figure 4When the first gear 1704 is on the other side of the middle limit groove 1707, the first gear 1704 cannot continue to rotate, the rotation resistance of the connecting shaft 1703 increases, and the inner wall of the groove 1708 will squeeze the connecting block 1709 to compress the spring 1710 until the connecting block 1709 is completely retracted to the inside of the first gear 1704. At this time, the connecting shaft 1703 will slide inside the first gear 1704, thereby closing the water extraction hole formed by the third through hole 19 on the second cylinder 10 and the fourth through hole 20 on the inner cylinder 18. The continuous rotation of the connecting shaft 1703 will drive the second gear 24 to rotate, and the rotation of the second gear 24 will drive the second gear ring 25 to rotate. The rotation of the second gear ring 25 will drive the guide drill 11 and the drilling frame 12 to rotate. The guide drill 11 will rotate under the slip ring 26, and the guide ring 23 rotates on the slider 22 at the bottom of the connecting shaft 1703 through the slide groove 27, so that the device drives the entire device to continue to drill downward while the pumping hole is closed. After the device moves to a suitable area of ​​the gravel layer, the waterproof motor 1702 drives the connecting shaft 1703 to rotate in the opposite direction, thereby opening the pumping hole formed by the third through hole 19 on the second cylinder 10 and the fourth through hole 20 on the inner cylinder 18 to a suitable size for pumping water. When pumping water, an external pipe is connected at the first through hole 7 and the second through hole 8, and the groundwater is pumped into the interior of the outer shell 6 through the first connecting pipe 15 and the second connecting pipe 16 on the water pump 14, and then the groundwater is pumped into the cavity between the first cylinder 1 and the inner plate 13 through the first through hole 7 and the second through hole 8 and the external pipe, thereby increasing the overall weight of the device to overcome the resistance of drilling downward in the gravel layer. The groundwater in the cavity between the first cylinder 1 and the inner plate 13 can be discharged later through the external pump body.
