Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a foundation pit dewatering construction structure. Background Art

[0002] Foundation pit dewatering, also known as foundation pit drainage or foundation pit dewatering, refers to the process of taking measures to lower the groundwater level in and around the foundation pit in order to ensure the safety and smooth progress of the construction when conducting underground projects (such as building foundation construction, subway tunnel excavation, etc.). The purpose of foundation pit dewatering is to create a dry working environment to avoid the impact of groundwater on construction, such as soil liquefaction, foundation pit collapse, and reduced foundation bearing capacity. Common foundation pit dewatering methods include open ditch drainage, well point dewatering, water-stop curtain method, deep well dewatering method, etc. The deep well dewatering method is to drill a deep well near or inside the foundation pit and use a water pump to pump out groundwater to achieve dewatering.

[0003] When a water pump is used to extract groundwater from a precipitation well, blockages such as fine stones and mud in the precipitation well will be sucked into the water pump, causing the performance of the water pump to decrease; and the blockages will be deposited in the precipitation well, affecting the precipitation effect of the precipitation well.

[0004] In view of this, the purpose of the utility model is to provide a foundation pit dewatering construction structure which can filter blockages such as fine stones and mud in a dewatering well and discharge the blockages out of the dewatering well. Utility Model Content

[0044] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0045] A foundation pit dewatering construction structure includes a dewatering well 1 and a filter box 2 arranged in the dewatering well 1, the filter box 2 includes a water pumping bucket 201 and a filter barrel 202 fixedly arranged on the water pumping bucket 201, a water inlet 203 is arranged on the filter barrel 202, a side wall portion of the water pumping bucket 201 penetrates into the filter barrel 202 to form a water filter port 204, a filter net 205 is arranged at the water filter port 204, a water pump 3 is arranged in the water pumping bucket 201, and a water outlet of the water pump 3 is inserted through the water pumping bucket 201 and connected with a drainage pipe 4.

[0046] Specifically, a filter tube 101 is arranged in the precipitation well 1, and filter material 102 is filled between the filter tube 101 and the inner wall of the precipitation well 1, and clay 103 is filled between the filter tube 101 and the precipitation well 1 and above the filter material 102. The clay 103 can block the top of the precipitation well 1 to prevent surface water from flowing into the precipitation well 1. The filter material 102 can perform preliminary filtration on the groundwater, and then perform secondary filtration through the filter tube 101.

[0047] There are two filter barrels 202, which are arranged opposite to each other and fixedly installed on both sides of the water pumping barrel 201. The side walls of the filter barrel 202 and the side walls of the water pumping barrel 201 form a cylindrical shape, so that the side wall of the filter box 2 is cylindrical as a whole. The filter box 2 is arranged in the filter tube 101, and the side wall of the filter box 2 is fitted with the inner wall of the filter tube 101. When the filter box 2 is placed at the bottom of the precipitation well 1, it can fill the bottom of the filter tube 101 to prevent groundwater and sediment from sinking into the gap between the filter box 2 and the filter tube 101.

[0048] More specifically, the top surface of the water pump 201 is opened to form a placement opening 206, and the water pump 3 can be placed in the water pump 201 through the placement opening 206. The placement opening 206 is covered with a water baffle 207, and the water baffle 207 and the water pump 201 are fixedly connected by bolts; the water outlet of the water pump 3 is inserted through the top surface of the water baffle 207 and is arranged outside the water pump 201. The water outlet of the water pump 3 is connected with the drain pipe 4, and the drain pipe 4 extends to the outside of the precipitation well 1 to discharge the water in the water pump 201. The drain pipe 4 is assembled and connected by multiple sections;

[0049] After the groundwater enters the filter barrel 202 from the water inlet 203 on the filter barrel 202, the groundwater can enter the pumping barrel 201 through the filter net 205. The filter net 205 can isolate blockages such as fine stones and mud in the groundwater in the filter barrel 202, thereby preventing the blockages from entering the pumping barrel 201 and affecting the performance of the water pump 3; after the blockages are isolated in the filter barrel 202, they can be prevented from sinking to the bottom of the precipitation well 1 and affecting the precipitation effect of the precipitation well 1.

[0050] Furthermore, after a large amount of blockages have accumulated in the filter barrel 202, it is necessary to clean the blockages in the filter barrel 202; specifically, a pulling ring 5 is fixedly provided on the top surface of the water baffle 207, and two pulling rings 5 ​​are symmetrically arranged. A pulling rope 501 is hung on the pulling ring 5, and the filter box 2 and the water pump 3 can be placed in or pulled out of the precipitation well 1 through the pulling rope 501.

[0051] A support frame 502 is arranged outside the precipitation well 1, and the support frame 502 is placed on the ground. A top plate 503 is fixedly arranged above the support frame 502, and a bottom plate 504 is fixedly arranged below the support frame 502. Two mounting plates 505 arranged opposite to each other are fixedly installed on the top plate 503, and a reel 506 is arranged between the two mounting plates 505, and the reel 506 is rotatably arranged on the mounting plates 505; a driving motor 507 is fixedly arranged on one of the mounting plates 505, and the output shaft of the driving motor 507 is fixedly connected to the reel 506 and is coaxially arranged; one end of the pulling rope 501 away from the pulling ring 5 is fixedly connected to the reel 506, and a part of the pulling rope 501 is wound on the reel 506, and a surface part of the top plate 503 is penetrated to form a pulling opening 508 for the pulling rope 501 to pass through; a surface part of the bottom plate 504 is penetrated to form an insertion opening 509 for the filter box 2 to pass through;

[0052] By starting the drive motor 507, the pulling rope 501 can be released and the filter box 2 can be placed in the filter tube 101. After the drive motor 507 rotates in the opposite direction, the pulling rope 501 can be reeled in and the filter box 2 can be pulled out of the filter tube 101. After the filter box 2 is pulled out of the filter tube 101, the blockage in the filter barrel 202 can be manually cleared.

[0053] Furthermore, two relatively arranged limit plates 510 are fixedly installed on the bottom plate 504, and a load-bearing plate 511 is movably arranged inside the limit plate 510. When the filter box 2 is pulled out of the filter tube 101, the load-bearing plate 511 is moved to be placed under the filter box 2. After releasing the pulling rope 501, the filter box 2 can be placed on the load-bearing plate 511.

[0054] In order to facilitate movement, a support leg 512 is fixedly installed on the bottom surface of the bottom plate 504, and a universal wheel 513 is rotatably installed on the bottom surface of the support leg 512.
