Description

Foundation pit drainage anti-blocking system

Technical Field

The utility model relates to a drainage system field specifically is a stifled system is prevented in foundation ditch drainage.

Background

The drainage of the foundation pit refers to that when the foundation pit is excavated, the underground water level is higher than the excavated bottom surface, and the underground water can continuously seep into the pit, so that the construction of the foundation pit under a dry condition is ensured, and the precipitation work is performed to prevent slope instability, basic quicksand, pit bottom uplift, pit bottom piping and foundation bearing capacity reduction.

Because the water in the well point often has impurity such as mud piece and grit, the existence of these impurity can cause the damage to pumping equipment such as water pump, so the water in the well point often can pass through the filtration of filter screen earlier before the water pump. But along with pumping equipment's operation, often can adhere to more impurity on the filter screen, if not change and clear up the filter screen, will influence the normal discharge of water in the well point, and then need carry out comparatively frequent change and washing to the filter screen through the manual work, waste time and energy, the change process is very troublesome.

Like 201821896667.4, be named as "a foundation ditch drainage structures", when the filter screen adheres to more clod and grit, rotatory rolling disc drives the filter screen and rotates, when another filter screen rotatory to just right to with the passageway opening, second locking mechanical system locks the position of rolling disc, has reached the purpose of changing the filter screen promptly. However, as the water impurity particles in the foundation pit are more, the filter screen is easy to block during filtering, and the operation of the water pump needs to be stopped during the filtering and replacing process, so that the operation of drainage operation is stopped, and the working efficiency is affected.

In order to solve the problems, the scheme is developed accordingly.

Detailed Description

The invention is explained in more detail below with reference to the figures and examples.

As shown in fig. 1-4: the utility model provides a stifled system is prevented in foundation ditch drainage, includes that the barricade 2, the water pump 3 that set up at 1 lateral wall in foundation ditch, connect respectively in the drinking-water pipe 4 and the drain pipe of 3 outputs of water pump, inputs, in the extension end of drinking-water pipe 4 extended foundation ditch 1, the lower extreme of barricade 2 is vertical to be wedged at 1 hole bottom in foundation ditch, still including preventing stifled component 5, prevents that the upper and lower both sides of stifled component 5 link up, and in its downside was put into foundation ditch 1, the upside communicated with each.

The anti-blocking member 5 includes a box body 51 with an open bottom and a pipe joint 52, wherein a plurality of connecting pipes 54 are communicated with the pipe joint 52, the connecting pipes 54 are communicated with the box body 51 through filter pipes 53, and the connecting pipes 54 are connected with the filter pipes 53 through threads. The method specifically comprises the following steps: the lower extreme of multidirectional siphunculus 6, connecting pipe 54, the outer wall of filter tube 53 all are equipped with thread groove 7, through 8 threaded connection of thread bush between multidirectional siphunculus 6 and the filter tube 53, and connecting pipe 54 passes through 8 threaded connection of thread bush with filter tube 53, are convenient for carry out the high-speed joint, pass through threaded connection between filter tube 53 and the box 51.

The box body 51 is extended with a multi-directional through pipe 6, and each direction of the multi-directional through pipe is communicated with the filtering pipe 53 and the connecting pipe 54 one by one.

The coupling 52 is connected to the connector 54 by snap-fitting. Specifically, a sliding sleeve 9 and a positioning ring 10 are arranged outside the connecting pipe 54, a clamping rod 11 is arranged on one side of the sliding sleeve 9, a clamping joint 12 is arranged at the end part of the clamping rod 11, the clamping rod 11 has elasticity, a clamping groove 13 is arranged at the corresponding position on the pipe joint 52, and when the connecting pipe 54 moves to abut against the positioning ring 10, the clamping joint 12 is clamped with the clamping groove 13.

It should be noted that the inner side of the card slot 13 extends inwards, the cross section of the card connector 12 is trapezoidal, and the outer side of the card connector 12 is a bevel edge protrusion, and the card connector 12 is matched with the card slot 13 in size.

Because the connecting pipe 54 in this solution belongs to the rigid pipe, unlike the flexible pipe which can be bent, after the lower end of the connecting pipe 54 is disassembled, the whole rigid pipe still keeps the original position, so that the top of the connecting pipe 54 can be disassembled quickly through the clamping rod 11 and the clamping head 12.

As shown in fig. 4, the manner of detaching the clamping rod 11 and the clamping head 12 from the clamping groove 13 mainly includes: the clamping rods 11 with certain elasticity (the two clamping rods 11 have opening force towards opposite sides respectively) are extruded inwards, the clamping head 12 is driven to deviate towards the inner side and stagger with the clamping groove 13, and quick disassembly is achieved.

The use process of the anti-blocking component 5 is as follows: firstly, the threaded sleeve 8 is rotated to be separated from the filter pipe 53, and meanwhile, the clamping rod 11 is extruded inwards, so that the clamping connector 12 is separated from the clamping groove 13, the connecting pipe 54 is disassembled, at the moment, the connecting part between the pipe connector 52 and the connecting pipe 54 is sealed through a sealing cover, and other connecting pipes 54 are not stopped for continuous operation; the filtering pipe 53 and the multi-way pipe 6 are disassembled and replaced by continuously rotating the threaded sleeve 8.

The retaining wall 2 of the foundation pit 1 positioned on the side wall is a low-lying part 14, a water flowing groove 15 is horizontally arranged in the foundation pit 1, the water flowing groove 15 is communicated into the low-lying part 14, and the lower side of the box body 51 is arranged in the low-lying part 14.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and the protection scope must be determined by the scope of the claims.
