Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 and 2, the anti-blocking isolation water tank provided by the present invention comprises an isolation box 1 and a filter box 2, wherein the filter box 2 is arranged in the isolation box 1. The isolation box 1 comprises a box body 101 and a box cover 102, wherein the box cover 102 is hinged on the box body 101, a first pipe opening 103 is formed in the middle of the box cover 102, and the first pipe opening 103 is used for connecting a pipeline of an external water pump or other water pumping facilities. The box cover 102 and the box body 101 are both provided with a plurality of isolation holes 105, the isolation holes 105 are uniformly distributed along the surface of the isolation box 1, and the isolation holes 105 are mainly used for allowing water in a foundation pit to enter the isolation box 1 and simultaneously isolating sand blocks and stones with larger external sizes of the box. In order to ensure the structural stability of the isolation box 1, rib plates 104 are also connected to the box cover 102 and the box body 101.

The filter box 2 is composed of a bottom cover 201 and an upper box body 202, and the bottom cover 201 is detachably connected with the upper box body 202. A large number of small bosses 204 are densely distributed on the filter box 2, and the small bosses 204 are radially distributed on the filter box 2 in the center. The cross-sectional shape of little boss 204 is isosceles trapezoid to all seted up through-hole 205 on every little boss 204, the direction of through-hole 205 all points to the central point of rose box 2. And a layer of screen 206 is also provided at the orifice of the through-hole 205. Wherein, the bottom surface of the bottom cover 201 of the filter box 2 is a plane, when the filter box 2 is arranged in the isolation box 1, the bottom cover 201 of the filter box 2 contacts with the inner wall of the isolation box 1. The top of the upper box 202 is provided with a second nozzle 203, and the second nozzle 203 is matched with the first nozzle 103 for connecting the pipeline of the pumping facility. Meanwhile, a net bag 3 is connected to the second pipe mouth 203, and the net bag 3 is used for supporting and limiting a water pumping pipeline after extending into the filter box 2.

The through holes 205 provided in the filter box 2 are intended to "filter" the water flow that has been primarily "filtered" by the separator box 1 again. Referring to fig. 3, the isolation box 1 is used for filtering out sand with larger size existing in a foundation pit, the water flow entering the isolation box 1 through the isolation holes 105 also contains a large amount of small-size gravel, when the water flow containing the small sand enters the filter box 2 through the through holes 205 on the filter box 2, the small bosses 204 are arranged on the small bosses 204, the cross sections of the small bosses 204 are in an isosceles trapezoid shape, concave curved surfaces are formed between the small bosses 204 and the small bosses 204, and the flow velocity of the water flow is influenced by the flow velocity of the water flow (due to the viscosity of the fluid, the velocity of the fluid flowing through each point on the cross section of the pipeline is different, the velocity of the fluid is changed along the radius of the pipeline is fastest, the velocity of the fluid is slower away from the center, the velocity of the fluid is zero at the pipe wall, when the particles in the fluid pass through a narrow part, due to the difference of the velocities of different parts of the fluid, the particles in the fluid collide with the inner wall of the bend, the pipe, the regional rotation diameter change is obvious, the sand particles in the water flow are blocked between the small-sized sand and the small bosses 204 and the filter box 2, and the possibility of entering the filter box 2 is further reduced by the through holes 205. In order to ensure the "filtering" effect, it is clear that the diameter of the isolating aperture 105 is larger than that of the through-holes 205 of the filter box 2, and since the diameter of the through-holes 205 is relatively small, the number of the through-holes 205 of the filter box 2 is as large as possible so as not to affect the pumping rate.

When (dark) foundation ditch precipitation, place rose box 2 in the inside of shielded cell 1, connect the outside pipeline of drawing water through first mouth of pipe 103 and second mouth of pipe 203 in proper order, the pipeline mouth then is located rose box 2 inside string bag 3 this moment. During precipitation, water in the (deep) foundation pit is subjected to primary filtration through the isolation box 1 to remove stones with relatively large sizes or other substances which are not dissolved in water, and water entering the box through the isolation holes 105 and carrying a large amount of gravel is subjected to secondary filtration through the small bosses 204, the through holes 205 and the filter screen 206 on the filter box 2 to prevent the gravel with relatively small sizes from entering the filter box 2 as much as possible, so that the possibility of blockage of the water pumping facility pipeline is reduced. The frequent cleaning and maintenance of pipelines and pumping facilities are avoided, and the precipitation efficiency is improved to a certain extent.

Because the water tank is mostly used for (deep) foundation pit dewatering, and the isolation box 1 has no strict technical requirements, the materials used for manufacturing the isolation box 1 can be used as local materials, and only waste wood of a construction site is used. The filter box 2 only needs to be taken out, and the bottom cover 201 is disassembled to clean the inside periodically. When the isolation box 1 is damaged, the isolation box 1 is simple in structure, and only needs to be replaced and manufactured again. Therefore, by utilizing waste, not only can the engineering waste materials be recycled, but also the cost is saved.

The foregoing is illustrative of the preferred embodiments of the present invention, and it is to be understood that the invention is not limited to the precise forms disclosed herein, and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the invention as defined by the appended claims. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.
