[0002] Building construction projects refer to various building constructions and their ancillary facilities, as well as the installation projects of pipelines, equipment and their supporting lines, and interior and exterior decoration projects. A foundation pit is an earth pit excavated at the designed position of the foundation according to the base elevation and the foundation plane size. Stones on the slope can enter the inserted pipe, which may cause damage to the geotextile and result in the geotextile losing its filtering function.

[0003] In view of the above technical problems, for example, the drainage structure for foundation pit support in building construction projects disclosed in the publication number CN217923686U moves the filter frame out of the drain pipe to facilitate the cleaning of the filter frame, thereby reducing the possibility of drain pipe blockage, and is conducive to filtering stones and mud to protect the normal use of the geotextile;

[0004] Although the above patent can achieve the anti-blocking effect, in the actual use process, its drainage effect is poor, the water cannot be drained quickly, and it is not conducive to guiding and discharging the accumulated water deposited at the bottom below. Content of the Utility Model

Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 to 4 , the present invention provides a foundation pit drainage device for building construction projects, including a foundation pit body 1 and a drainage mechanism 2. The drainage mechanism 2 is arranged on one side of the top of the foundation pit body 1. The pump 21 in the drainage mechanism 2 is arranged on one side of the top of the foundation pit body 1, and the pump 21 is used to play the role of power extraction during drainage;

[0024] It also includes a connecting pipe 22, a hose 23, an extraction head 24, a protective shell 25, a first water collecting tank 26 and a second water collecting tank 27. The connecting pipe 22 is connected to the water inlet end of the pump 21 through a pipeline. The hoses 23 are respectively connected to both sides of the surface of the connecting pipe 22. The extraction head 24 is connected to one end of the hose 23. The protective shell 25 is installed outside the extraction head 24. The first water collecting tank 26 is opened on one side of the top of the inner cavity of the foundation pit body 1, and the second water collecting tank 27 is respectively opened on both sides of the bottom of the inner cavity of the foundation pit body 1;

[0025] The cooperation of the connecting pipe 22 and the hose 23 facilitates the water delivery work during drainage. The extraction head 24 is located at the bottom of the inner cavity of the foundation pit body 1 and can directly absorb and extract the accumulated water. At the same time, the protective shell 25 is beneficial to the installation and protection of the extraction head 24, and the cooperation between the first water collecting tank 26 and the second water collecting tank 27 is beneficial to the diversion of a small amount of accumulated water, so as to facilitate its stable extraction.

[0026] During operation, directly place the extraction head 24 and the protective shell 25 in the foundation pit body 1. After placing them in the required position, start the pump 21. The pump 21 directly extracts through the extraction head 24 and is conveyed by the connecting pipe 22 and the hose 23, so as to extract it into the required pipeline for discharge;

[0027] And when there is a small amount of accumulated water in the foundation pit body 1, since the second water collecting trough 27 is arranged in a slope, the water will flow into the interior of the first water collecting trough 26, thus playing a role in guiding the accumulated water.

[0028] In addition, a protective cover is installed on one side of the top of the foundation pit body 1, and the pump 21 is located inside the protective cover. The protective cover can facilitate the auxiliary installation of the pump 21 and also play a protective role.

[0029] Preferably, an adjustment mechanism 3 is arranged inside the foundation pit body 1. The adjustment mechanism 3 includes a support and guiding component and a connection component. The support and guiding components are respectively arranged on both sides of the top of the foundation pit body 1, and the connection component is arranged on the top of the support and guiding component. The cooperation of the support and guiding component and the connection component facilitates the removal of the protective shell 25.

[0030] Among them, the support and guiding component includes a bracket 31 and a pulley 32. The brackets 31 are respectively installed on both sides of the top of the foundation pit body 1, and the pulley 32 is movably installed inside the bracket 31. The bracket 31 facilitates the movable installation of the pulley 32 and can also fix the pulling rope 33, while the pulley 32 makes it more labor-saving when pulling.

[0031] Among them, the connection component includes a pulling rope 33 and a connection seat 34. The pulling rope 33 is installed on the top of the bracket 31, and the connection seat 34 is installed on the top of the pulling rope 33. The pulling rope 33 plays a role in connection and facilitates people's pulling work. In addition, the connection seat 34 facilitates its direct pulling.

[0032] During operation, directly pull the pulling rope 33. At this time, the pulling rope 33 needs to fit the pulley 32, and the pulley 32 will directly drive the connection seat 34, and the connection seat 34 will drive the protective shell 25 to move upward until the protective shell 25 is removed.

[0033] Furthermore, grooves are opened on both sides of the back surface of the inner cavity of the foundation pit body 1. Limiting grooves are opened on both sides of the inner wall of the groove. A limiting block is slidably connected inside the limiting groove. One side of the limiting block is installed on the outer side of the protective shell 25. The cooperation among the groove, the limiting groove and the limiting block not only facilitates the limitation of the position of the protective shell 25, thus ensuring that it is stably in the required position, but also avoids deviation during taking and placing, facilitating people's operation.

[0034] When taking or placing the protective shell 25, it is always located inside the groove, and at the same time, due to the sliding connection between the limiting groove and the limiting block, it plays a role in limiting and assisting the position movement.

[0035] In addition, a separation net 4 and an adsorption net 5 are arranged on the surface of the protective shell 25. The separation net 4 and the adsorption net 5 are installed on the surface of the protective shell 25 through bolts. The separation net 4 and the adsorption net 5 can effectively play a filtering role to prevent the sediment in the accumulated water from blocking the extraction head 24, which not only is not conducive to the extraction of the accumulated water, but also easily causes damage to it.

[0036] The separation net 4 can be used to block and filter slag stones and sundries, while the adsorption net 5 is conducive to filtering and blocking smaller impurity particles, thereby improving the filtering effect, and the replacement operation can be carried out by rotating the bolt.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
