Detailed Description

The technical scheme of the utility model is explained in detail in the following with the attached drawings:

referring to fig. 1 and 3, the sectional type flood protection wall comprises concrete piers 1 arranged at two sides in a roadway, a wall body with two ends respectively connected with the piers 1, a waterproof cloth 4 laid at the outer side of the wall body, and flood protection sand 5 stacked at the outer side of the waterproof cloth 4. The pier body 1 on one side is provided with a hinge 2.

Referring to fig. 1, in this embodiment, the wall includes three sets of telescopic fence assemblies 3 arranged up and down, and the telescopic fence assemblies 3 are made of steel pipes and include a frame portion 3-1 and a telescopic portion 3-2 capable of horizontally extending and contracting relative to the frame portion 3-1.

One end of each telescopic fence component 3 is inserted into the hinge 2 to rotate relative to the pier body 1 on the side, and the other end of each telescopic fence component is in contact with the pier body 1 on the other side. If the width of the section of the roadway is wide, the other end of the roadway needs to be fixedly connected with the pier body 1 on the other side. During fixed connection, the threaded column can be pre-embedded on the pier body 1, then the pressing plate is used for pressing the other end of the telescopic fence component 3, the threaded column penetrates through the pressing plate, and then the nut is arranged on the threaded column to fix the pressing plate.

As shown in fig. 2, the frame part 3-1 comprises a first connecting column 3-1-1 which is vertically arranged and is used for being inserted into the hinge 2, and also comprises an upper group of first horizontal pipes 3-1-2 and a lower group of first horizontal pipes 3-1-2; the left ends of the two groups of first horizontal pipes 3-1-2 are respectively fixedly connected with the upper end and the lower end of the first connecting column 3-1-1, the two groups of first horizontal pipes 3-1-2 are also connected through a plurality of upright columns 3-1-3, and the other end of each first horizontal pipe 3-1-2 is provided with an opening.

The telescopic part 3-2 comprises an upper group of second horizontal pipes 3-2-1 and a lower group of second horizontal pipes 3-2-1, one ends of the two groups of second horizontal pipes 3-2-1 are respectively inserted into the open holes of the two groups of first horizontal pipes 3-1-2 to realize sliding telescopic, and the other ends are mutually connected through a second connecting column 3-2-2.

In this example, the first horizontal pipe 3-1-2 is a 1.5-inch seamless pipe, and the second horizontal pipe 3-2-1, the first connecting column 3-1-1, the second connecting pipe, and the upright column 3-1-3 are 1.2-inch seamless pipes. The height of each section of fence is 0.4 m, the upper limit of the height of the three sections of fences is 1.4 m, the lower limit of the width is 1.8 m, and the upper limit is 3 m.

As an alternative embodiment, it is also possible to replace the upright posts 3-1-3 and the first connecting post with a one-piece metal sheet; it is also possible to use the entire metal plate as the frame part 3-1, on which a sliding groove is provided in sliding engagement with the telescopic part 3-2. Obviously, the method of the embodiment is the simplest and the most economical.

As shown in fig. 3, the waterproof cloth 4 is overlapped at the bottom thereof with the roadway surface, and the flood control sand 5 is stacked at the overlapped position.

During installation, the telescopic fence component 3 is inserted on the hinge 2 according to the water quantity condition, then is adjusted to a proper length and is rotated to a position vertical to a roadway, so that the other end of the fence is in contact with or fixedly connected with the pier body 1 on the other side. Then laying waterproof cloth 4, and finally stacking flood control sand 5 to form the wall body. When the water quantity is changed, the telescopic fence component 3 can be continuously installed and dismantled according to the requirement, so that the device can be recycled.

Novel flood control wall has solved plank processing difficulty, short-lived, the low, unable cyclic utilization's of intensity problem, and is more advantageous in the cost moreover: the cutting and the transportation of the flood control board in the Jiuqu mining area need to consume at least 60 people's labor cost every year, each traditional flood control wall needs to consume 0.11 cubic of boards, the cost is 230 yuan, and the cost for replacing the boards in the mining area every year is 17388 yuan. The cost of a single fence of the novel flood control wall is about 300 yuan, although the one-time investment is slightly higher than that of the traditional plate wall, the service life is at least more than five years, and the service life can be further prolonged through periodical corrosion prevention. If the period of five years is taken as a period, the cost of the new flood wall can be saved by 54500 yuan compared with the traditional flood wall.
