Embodiment 1
[0036] Embodiment 1, the present invention is a water collection and drainage device for a deep foundation pit in traffic construction, including a dewatering well and a dewatering well platform 1 fixedly installed on the crown beam of the foundation pit. The dewatering well platform 1 is provided with a control device that can control the hoisting The water pump in the dewatering well and the dewatering well in the foundation pit start after the foundation pit is excavated to break the pavement concrete, and it is carried out synchronously with the pouring of the crown beam. On the beam, specifically, the dewatering well platform 1 is fixed on the crown beam through expansion screws, and the water pump is hoisted from the dewatering well platform 1 to a suitable position in the dewatering well by ropes, usually directly at the base level or slightly higher than the base level position, it is characterized in that, described dewatering well comprises the upper well pipe 2 and t...
Embodiment 2
[0038] Embodiment 2. On the basis of Embodiment 1, this embodiment provides a specific structure in which the rotation of the mouthpiece 5 drives the outer shell 7 to rotate, so as to achieve the effect that the rotation of the inner shell 6 can drive the outer shell 7 to rotate synchronously, and at the same time, the inner shell can 6 and the casing 7 have different rotational speeds, so as to facilitate the cleaning of the brush 8. Specifically, the rotating structure includes an upper sun gear 10 coaxially fixedly connected with the mouthpiece 5, and the upper sun gear is engaged with a rotating connection The upper planetary gear 11 on the support frame 4, the upper planetary gear 11 is externally meshed with the upper ring gear 12 fixedly connected to the upper end surface of the housing 7, that is, the rotation of the mouthpiece 5 drives the upper sun gear 10 to rotate synchronously , so as to drive the rotation of the upper planetary gear 11 connected to the support fra...
Embodiment 3
[0039] Embodiment 3, on the basis of Embodiment 2, this embodiment provides a specific structure in which the mouthpiece 5 rotates to drive the brush 8 to rotate, so that the rotation speed of the brush 8 is different from that of the outer shell 7 and the inner shell 6, so that The brush 8, the outer shell 7, and the inner shell 6 all have relative motion. At the same time, because the outer shell 7 deposits more sediment and large particles, it is necessary for the brush 8 to have a relatively fast relative speed relative to the outer shell 7. Specifically, the The upper end surface of the shell 7 described above is rotatably connected with the lower gear ring 13, and several of the brushes 8 are fixedly connected to the lower end of the lower gear ring 13, that is, the rotation of the lower gear ring 13 can drive several brushes 8 to rotate synchronously. Figure 5 The brush 8 is set as a brush 8 with bristles only towards the side of the outer shell 7 and towards the side o...
