Technical Field
[0001] The utility model relates to the field of water conservancy projects, in particular to a novel retaining wall for water conservancy projects. Background Art
[0002] In a water conservancy river channel, if river sand accumulates for a long time, it may cause siltation and riverbed rise, causing dangerous conditions on both sides of the river channel. If a retaining wall is set up upstream of the river channel to intercept the river sand and soil inside the river channel, the dangerous conditions downstream will be alleviated to a great extent. The traditional retaining wall structure design is single and the effect is not good. Moreover, it can only clean the silt in the river channel in the dry season. The river channel cleaning work is not efficient enough. Therefore, a new type of water conservancy project retaining wall is designed. Utility Model Content

DETAILED DESCRIPTION
[0011] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementations.
[0012] A novel retaining wall for a water conservancy project comprises a water blocking dam body 1, a sand blocking dam body 2, a mixed flow structure 3, and an underground dam body 4. The water blocking dam body 1 and the sand blocking dam body 2 are arranged in parallel, the underground dam body 4 is arranged on the bottom sides of the water blocking dam body 1 and the sand blocking dam body 2, and the water blocking dam body 1, the sand blocking dam body 2, and the underground dam body 4 are integrally cast and formed, an overflow port 5 is provided on the top side of the water blocking dam body 1 and the top of the sand blocking dam body 2, a sand blocking groove 6 is provided between the water blocking dam body 1 and the sand blocking dam body 2, a mixed flow structure through hole 7 is provided on the water blocking dam body 1 and the sand blocking dam body 2, the mixed flow structure 3 is inserted and fixed in the mixed flow structure through hole 7, and the mixed flow structure 3 is correspondingly arranged on the bottom side of the overflow port 5, and the height of the water blocking dam body 1 is higher than that of the sand blocking dam body 2.
[0013] The mixed flow structure 3 is composed of a threaded steel rod 8, a horseshoe 9, and a fixing bolt 10. The threaded steel rod 8 is provided with a horseshoe fixing groove 11. The horseshoe 9 is correspondingly sleeved on the outside of the horseshoe fixing groove 11. The fixing bolt 10 is fixed on the horseshoe 9. The threaded steel rod 8 is inserted into the mixed flow structure through-hole 7. The horseshoe fixing groove 11 is correspondingly opened with a length close to the two sides of the water blocking dam body 1 and the sand blocking dam body 2. The horseshoe 9 is fixedly arranged on the outside of the port of the mixed flow structure through-hole 7.
[0014] Working principle of the utility model: the design of the retaining wall utilizes the action of water flow to deposit silt in the sand blocking groove 6. The water blocking dam body 1 is used to block the water flow in the river channel, so that the water flow rises, and the water flow carrying silt flows out through the overflow port 5 on the upper side of the water blocking dam body 1. The outflowing water flow directly falls on the mixed flow structure 3. Through the cutting and blocking action of multiple groups of threaded steel rods 8, the effect of the water flow impact is weakened, and the silt in the water flow is deposited inside the sand blocking groove 6. Under continuous accumulation, the water level rises and flows out through the overflow port 5 on the sand blocking dam body 2. The silt gradually accumulates in the sand blocking groove 6, which can facilitate the dredging work of the suction equipment. The impact and friction effect of the silt will cause the mixed flow structure 3 to wear, and the design of the mixed flow structure 3 is convenient for replacement.
[0015] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
