Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses headwall with scour prevention function. Referring to fig. 1 and 2, the tooth wall with scour prevention function is provided with reinforcing platform 2 under the tooth wall body 1 including setting up tooth wall body 1 that the concrete in river course both sides was made, and reinforcing platform 2's one end stretches out tooth wall body 1 and keeps away from the lower limb in river course, and tooth wall body 1 slope sets up and the lower extreme is close to the river course.

Referring to fig. 1 and 2, in the construction process, the channel is placed before the two sides of the river channel are dug, the length direction of the channel is placed along the flow direction of the river channel, then the template is erected at the position of the channel, and the tooth wall body 1 and the reinforcing platform 2 are integrally cast and formed.

Referring to fig. 1 and 2, after the dental wall body 1 is formed, a composite geomembrane layer is laid on the upstream surface of the dental wall body 1 to serve as a waterproof layer 3, so that the composite geomembrane is low in manufacturing cost and suitable for large-scale use. After the composite geomembrane layer is laid, a plurality of reinforcing frames 6 are fixedly connected to the slope surface of the o-tooth wall body 1 through a bar-planting anchoring technology, and the reinforcing frames 6 are of rectangular frame structures.

Referring to fig. 1 and 2, after the reinforcing frames 6 are arranged, alien soil is sprayed on the slope surface of the tooth wall body 1, the alien soil uniformly falls into each reinforcing frame 6 to form an alien soil layer 4, and geotextile 7 is laid on the alien soil layer 4. The reinforcing frame 6 has a blocking effect on the foreign soil, so that the foreign soil is prevented from being taken away by flushing water, and the geotextile 7 has a blocking effect on the foreign soil, so that the protection on the foreign soil layer 4 is further enhanced.

Referring to fig. 1 and 2, after the alien soil is sprayed, vegetation is planted on the alien soil to form a vegetation layer 5, the alien soil layer 4 has a storage effect on water rushing up the tooth wall body 1, the limit water level in a river channel can be effectively reduced, and meanwhile, the vegetation layer 5 effectively prevents the water in the river channel from taking away the alien soil when the water rushes out the tooth wall body 1, so that the effect of protecting the alien soil layer 4 is achieved.

Referring to fig. 1 and 2, in order to protect the vegetation layer 5, prevent that the excessive ponding in the reinforcement frame 6 from influencing vegetation growth, also prevent to cause soil erosion and water loss when the excessive ponding spills over in the reinforcement frame 6, bury conduit 8 prefabricated by concrete in the soil dressing layer 4, the direction of length of conduit 8 is along the incline direction of dentate wall body 1, the cross-section of conduit 8 is trapezoidal, the flaring end of conduit 8 sets up to the opening, the open-ended orientation deviates from the domatic of dentate wall body 1, be provided with anti-package 9 in the conduit 8, the both ends on the direction of length of conduit 8 run through its reinforcement frame 6 of locating, the conduit 8 that sets up in the reinforcement frame 6 of following dentate wall body 1 direction of rising straight line communicates each other.

Referring to fig. 1 and 2, because visitor's soil layer 4 receives the restriction of reinforcing frame 6 size, its water storage capacity has also received the restriction, when reinforcing frame 6 in visitor's soil water content is too big, can influence the growth of vegetation in vegetation layer 5, can discharge surplus water in visitor's soil layer 4 through setting up aqueduct 8, play the effect of protection vegetation, anti-package 9 of straining plays the effect of avoiding aqueduct 8 to block up when the water guide, aqueduct 8 of intercommunication each other makes the ponding in adjacent department reinforcing frame 6 higher directly constantly discharge downwards through adjacent lower place aqueduct 8, reduce the influence of higher department ponding to lower department visitor's soil layer 4.

The implementation principle of the tooth wall with the anti-scouring function is as follows: tooth wall body 1 that the concrete was made is stronger for the structure of the tooth wall body 1 that the riprap formed, and tooth wall body 1 cooperation waterproof layer 3 that the concrete was made simultaneously has for the better waterproof nature of riprap, and consequently its scour resistance ability is also stronger, and to tooth wall body 1 back bearing structure's protectiveness better, the reinforcing platform 2 that sets up in the standing groove provides stronger support performance for tooth wall body 1.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
