Description

A slope with drainage ditches

technical field

The utility model relates to a side slope provided with drainage ditches, which belongs to the field of side slope drainage.

Background technique

The design of drainage system is an important part of slope design. If the drainage system is not perfect, it is likely to cause the instability of the slope. The drainage ditch is a common drainage channel in the drainage system, and it is set on the horse track as a horizontal drainage channel. When it rains, the water on the slope follows the slope, and the water in the slope reaches the drainage ditch through the drainage pipe, and finally discharges the slope through the drainage ditch.

Due to the limitation of land expropriation scope and excavation boundary, there is often not enough space to set up a horse track on the slope, or due to the constraints of geological conditions, etc., the horse track collapses and the lateral drainage facilities of the slope are damaged, especially for high slopes. In other words, there is a huge security risk.

Utility model content

The technical problem solved by the utility model is to set drainage ditches on the high side slopes where the bridleway has not been set up or the bridleway has collapsed.

The technical solution of the utility model is to provide a side slope provided with a drainage ditch, including a drainage ditch arranged outside the side slope and a support for supporting the drainage ditch, and the support is anchored on the side slope.

Further, a row of horizontal first anchor rods and a row of second anchor rods vertical to the slope surface are fixed on the slope, the first anchor rods are located above the second anchor rods, and the first anchor rods are set on the slope. The supporting concrete including the rod and the second anchor rod is provided with a drainage ditch above the supporting concrete.

Further, the drainage ditch and the supporting concrete are integrally formed by pouring concrete.

Further, the drainage ditch includes a first ditch wall, a second ditch wall and a ditch bottom, and the first ditch wall is arranged along the slope of the side slope.

Further, the vertical reinforcement mesh is fixedly connected to the first anchor rod and the second anchor rod, the top of the reinforcement mesh is higher than the first anchor rod, and the bottom of the ditch is made of poured concrete including the first anchor rod. The walls of the second ditch are made of poured concrete including steel mesh.

Further, the steel mesh is welded by transverse steel bars and vertical steel bars.

Further, the first ditch wall is made of shotcrete.

The utility model first arranges the first anchor rod and the second anchor rod on the side slope, and then sets a formwork on the anchor rod, and makes the drainage ditch with concrete. Connecting the steel mesh on the anchor rod and then pouring concrete can improve the strength of the drainage ditch. The bolts can be used in combination with the bolts used for the original support of the slope. The first ditch wall of the drainage ditch is arranged along the slope surface of the side slope, and the water on the side slope can easily flow into the drainage ditch. The first ditch wall can be made of shotcrete, which can prevent rainwater from scouring the side slope surface.

The beneficial effect of the utility model is that the drainage ditch is arranged on the side slope, the structure is simple, the construction is convenient, the cost is low, and the safety of the side slope can be increased.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

The utility model provides a side slope provided with drainage ditches, its structure is shown in Figure 1, a row of horizontal first anchor rods 1 and a row of second anchor rods 2 vertical to the slope surface 3 are fixed on the side slope , the first anchor 1 is located above the second anchor 2, the supporting concrete 4 including the first anchor 1 and the second anchor 2 is set on the slope, and a drainage ditch 5 is established above the supporting concrete 4, The gutter 5 and the supporting concrete 4 are integrally formed by pouring concrete. The drainage ditch 5 includes a first ditch wall 51 , a second ditch wall 52 and a ditch bottom 53 , and the first ditch wall 51 is made by spraying shotcrete on the slope surface 3 of the slope. Vertical reinforcement mesh is arranged in the second ditch wall 52, and the reinforcement mesh is connected with the first anchor rod 1 and the second anchor rod 2, and the reinforcement mesh is formed by welding the horizontal reinforcement bar 6 and the vertical reinforcement bar 7.

The construction method of establishing drainage ditches on the slope is as follows: first, a row of second anchor rods 2 is drilled along the vertical direction of the slope, and then a row of first anchor rods 1 is punched horizontally above the second anchor rods 2. Both the anchor rod 1 and the second anchor rod 2 reserve part of the length exposed on the slope; the transverse reinforcement 6 and the vertical reinforcement 7 are welded into a reinforcement mesh, and the reinforcement mesh is bound or welded on the first exposed slope. On the anchor rod 1 and the second anchor rod 2; the second anchor rod 2 can be used not only for the support of the slope, but also as the support of the drainage ditch; finally lay the formwork, and pour concrete, and then the drainage ditch 5 along the slope surface The first ditch wall 51 of the gutter 5 is obtained by spraying concrete on one side of the ditch.
