Detailed Description

The present invention will be further described with reference to the following examples, which are not intended to limit the scope of the present invention, but are intended to be covered by the appended claims in any way.

Referring to fig. 1-5, the utility model discloses an emergency device of earth and rockfill dam wave prevention dangerous situation, including a plurality of horizontal timber beams 1 and perpendicular timber pole 2. The vertical wood rods 2 are arranged on the transverse wood beam 1, the vertical wood rods 2 are vertically arranged with the transverse wood beam 1, and the two adjacent vertical wood rods 2 are arranged in a vertically staggered manner, so that a wood raft is formed. The fixed ligature has manger plate protective grating 3 on horizontal timber beams 1 and the perpendicular timber pole 2, and it has a plurality of pegs 5 to peg graft at the top of dykes and dams 4, erects timber pole 2 and is connected through 6 one-to-one of stay cord with timber pile 5, and connects through the rope between the timber pile 5. The down stone 7 is installed below the vertical wood rod 2 through a rope to ensure that the emergency device can effectively sink into water. Be located the 1 top of the horizontal timber beams at top and be equipped with the mounting groove, packing has stone 8 in the mounting groove for increase emergency device's weight improves emergency device's stability. Specifically, when the vertical wood rod 2 is installed, the end part of the vertical wood rod 2 protrudes out of the transverse wood beam 1 at the top, and the length of the water retaining protective fence 3 is consistent with that of the vertical wood rod 2. After the water retaining guard fence 3 is bound on the cross wooden beam 1, the water retaining guard fence 3, the vertical wooden rod 2 and the cross wooden beam 1 form an installation groove in a surrounding mode.

Preferably, the lower end of the timber pile 5 is wedge-shaped, and both sides thereof are wrapped with stainless steel protective skins, thereby increasing the rigidity of the timber pile 5 and enabling the timber pile to be easily inserted into the dam 4.

The water retaining protective grating 3 is a willow or reed handle. Wherein the willow branch is formed by bundling willow branches into willow branches; the reed bundle is formed by bundling reed and straw materials. The water retaining protective grating 3 is wrapped with gravels so as to increase the overall weight of the emergency device and improve the stability of the emergency device. In the embodiment, when the water retaining grille 3 is bound, willow bundles or reed bundles are firstly bound into small pillows of 20-25cm, broken stones are wrapped in the small pillows, and the small pillows are ensured to be capable of sinking when being placed in water. And then connecting the small sleepers into sleeper rows with the width of 1-2m and the length of 5-10m by using ropes to form a water retaining protective fence 3, and then binding the water retaining protective fence on the cross beam 1 and the vertical wooden rod 2.
