Detailed Description

The present application is described in further detail below with reference to figures 1-6.

Example 1

The embodiment of the application discloses drainage structures for landslide control. Referring to fig. 1 and 2, the drainage structure for landslide control includes a multi-stage drainage ditch 1, and the multi-stage drainage ditch 1 is connected end to form a drainage channel. Under rainwater weather, rivers can flow into in the escape canal 1 and discharge along escape canal 1 along massif 7 to reach hydrophobic purpose, be favorable to reducing the landslide, the environmental protection.

The drainage ditch 1 is a precast concrete piece, and the drainage ditch 1 can be processed and produced in a factory in priority and then transported to a construction site for assembly, so that the construction efficiency is improved. Two adjacent escape canals 1 can reserve the expansion joint of certain width when assembling, and the expansion joint intussuseption is filled with pitch china fir to it carries out waterproof sealing to irrigate pitch. When 1 emergence expend with heat and contract with cold or ground production differential settlement in escape canal, can cause 1 deformation in escape canal, can effectively reduce 1 emergence deformation in escape canal through setting up the expansion joint.

As shown in fig. 3 and fig. 4, the expansion joint department just is located and has seted up the pre-buried hole on the terminal surface of 1 mutual concatenations in escape canal, install embedded sleeve 13 in the embedded hole, expansion joint department is provided with two articulated connecting rods 5 together, two connecting rods 5 one-to-ones insert in embedded sleeve 13, mounting groove 131 has been seted up to embedded sleeve 13's inner wall, slidable mounting has inserted block 6 in mounting groove 131, be provided with spring or elastic rubber pad between the tank bottom of inserted block 6 and mounting groove 131, adopt the spring in this embodiment, set up the slot 61 with 6 looks adaptations of inserted block on the connecting rod 5, when connecting rod 5 pegs graft in embedded sleeve 13, inserted block 6 pegs graft in slot 61. Two adjacent escape canals 1 link to each other through connecting rod 5 between, when ground takes place to subside, connecting rod 5 plays the tractive effect to escape canal 1 to reduce the subsidence of escape canal 1.

As shown in fig. 1 and 5, two side walls of the drainage ditch 1 are divided into a water-facing side 11 and a water-backing side 12, the water-facing side 11 is higher than the water-backing side 12, a filter screen 2 is covered at an opening of the drainage ditch 1, two ends of the filter screen 2 are connected to the top surface of the water-facing side 11 and the top surface of the water-backing side 12, the filter screen 2 and the drainage ditch 1 are detachably mounted, and the filter screen 2 is directly covered on the drainage ditch 1; adopt filter screen 2 to articulate the form on escape canal 1 in this embodiment, the one end of filter screen 2 hinges on meeting water side 11 through the hinge. When one side of escape canal 1 does not have the highway, the stone can roll along the inclined plane of filter screen 2, and the stone is difficult for stopping and causes the jam of filter screen 2 mesh on filter screen 2.

A plurality of drain holes 111 are formed in the water facing side 11 of the drainage ditch 1, the drain holes 111 are distributed along the trend of the drainage ditch 1, the drain holes 111 are located below the ground and close to the ground surface, and the drain holes 111 can increase the hydrophobic quantity and reduce rainwater from permeating into the ground. In order to make the drainage smoother, the drainage hole 111 is arranged obliquely, one end of the drainage hole 111 close to the backwater side 12 is lower than one end far away from the backwater side 12, in order to reduce the blocking phenomenon of the drainage hole 111, the water inlet end of the drainage hole 111 is provided with the inverted filter layer 4, the inverted filter layer 4 is used for blocking sand and stone to allow water to flow into the drainage hole 111, the inverted filter layer 4 is made of sand, gravel or pebble with different particle sizes, the particles gradually increase along the direction of the water flow, the particles of any layer pass through the pores of the adjacent thicker layer, and the particles of the same layer do not move relatively. In this embodiment, the reverse filtering layer 4 is 3 layers, and when the water flows through the reverse filtering layer 4, the particles in the water are gradually filtered, thereby reducing the blockage of the water discharge hole 111.

Filter screen 2 can block great stone and block up escape canal 1, but the less stone of some granules can flow into escape canal 1, block up escape canal 1 in order to reduce these less granule stones, the one end intercommunication of escape canal 1 has grit chamber 3, the degree of depth of grit chamber 3 is greater than the degree of depth of escape canal 1, the effect of grit chamber 3 is the silt that is used for the settlement aquatic, thereby reduce the sediment in the bottom of escape canal 1, the quantity of grit chamber 3 is a plurality of, both can set up a escape canal 1 between two adjacent grit chambers 3, also can set up a plurality of escape canals 1 between two adjacent grit chambers 3. Silt stone is collected in grit chamber 3, and the operator can regularly clear up grit chamber 3, and the silt of retrieving can be recycled.

The implementation principle of this application embodiment drainage structures for landslide is: through the top installation filter screen 2 in escape canal 1, can effectively block in the great stone of volume rolls into escape canal 1, reduce escape canal 1 and take place the blocking phenomenon. Because the water facing side 11 and the water backing side 12 of the drainage ditch 1 are different in height design, when the stone rolls onto the filter screen 2, the stone is not easy to stop at the top of the filter screen 2, and meshes of the filter screen 2 are effectively prevented from being blocked by the stone; the water facing side 11 is provided with a plurality of drain holes 111, so that rainwater close to the ground surface can be drained into the drainage ditch 1 in time, the amount of water permeating underground is reduced, the drainage capacity of the drainage ditch 1 is further improved, and the landslide control capacity is improved.

Example 2

The difference between this embodiment and embodiment 1 is that, as shown in fig. 6, the height of the water-facing side 11 is lower than that of the backwater side 12, the filter net 2 is hinged to the water-facing side 11, and one end of the filter net 2 far away from the water-facing side 11 is lapped on the top of the backwater side 12. When one side of the drainage ditch 1 is a road, the stone blocks can be stopped on one side far away from the road under the action of the filter screen 2, so that the stone blocks cannot roll on the road.

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