Description

Recyclable slope lamination green protection grid

Technical Field

The utility model relates to a side slope protection technical field specifically is a but green protection check room of cyclic utilization's slope lamination.

Background

In recent years, the national infrastructure field is greatly developed, and the center of gravity of infrastructure gradually inclines to an area with poor geological conditions, which is a challenge and a chance for improving the construction technology. The problem of loose slope lamination of a high slope is a great challenge to the traditional slope protection mode, and the conventional slope protection methods at present comprise anchor rod frame beam protection, ecological bag accumulation protection, spray anchor net combined protection, masonry stone protection and the like.

The anchor rod frame beam protection is a scheme that an anchor rod is firstly driven in to fix a frame beam, and then concrete is injected into the frame beam. During construction, the point position of the anchor rod is determined, the anchor rod is installed after drilling and hole cleaning, then the frame beam is bound by reinforcing steel bars on site, then the template is erected, concrete is poured into the frame beam, then the concrete in the steel truss is maintained, and finally planting soil is backfilled. The anchor frame beam has the following disadvantages: 1. large components and inconvenient transportation; 2. concrete needs to be poured on the slope body, so that the influence on the surrounding environment is large; 3. the curing period of the cast-in-place concrete is too long; 4. digging a large square; 5. the dead weight is too big, and the soil layer easily collapses.

Pile up ecological bag protection is one kind and sets up the grass kind in the bag body in advance, then with piling up the bag body, cover the scheme on whole slope. During construction, the slope is excavated, one row of the slope bottom is paved, the second row is paved, and the rest is done in the same way until the whole slope is paved. The pile-up ecological bag slope protection has the following disadvantages: 1. the excavation workload is large; 2. the ecological bag is easy to slide down the slope; 3. the survival rate of the seeds cannot be guaranteed.

The combined protection of spray anchor net is a scheme of using spray concrete and reinforcing bar net to seal slope surface and using anchor rod to reinforce slope surface. During construction, anchor rods with certain length and distribution are constructed in a rock body and act together with the rock body to form a complex, so that the strength of the rock body is made up for the deficiency, the anchoring effect is exerted, and the stability of the side slope is ensured. Meanwhile, the reinforcing mesh is arranged on the slope surface to spray concrete, so that the effect of restraining the slope surface from deforming is achieved, and the whole slope surface is integrated. The spray anchor net combined protection has the following defects: 1. the concrete needs to be sprayed on site, and the influence on the surrounding environment is large; 2. the application range is small, the method is not suitable for clay slope with poor diagenesis, and can not be directly used in water gushing areas, and the slope can be used without water backflow after water drainage; 3. after the anchor rod, the reinforcing mesh and the concrete are aged, the protection is insufficient.

The mortar rubble protection is a scheme that adopts masonry structure to be used for combining with the mortar so as to realize the bank protection function. During construction, the rubbles are cleaned firstly, then the mortar is stirred by a stirrer, and then the mortar is filled into the masonry joint, so that the sticking is realized. The grout rubble protection shortcomings are as follows: 1. the self weight is large, and the falling is easy; 2. the application range is limited, and the framework revetment is only suitable for general more stable soil layers and stone slopes and is not suitable for steep slopes with less stable soil; 3. the construction requirement is high, the protective performance tests the construction quality, the vertical slope from bottom to top of the rubble is built into a folded or arched framework, and the masonry can play a role only by being stable and compact.

The inner side of the grid is provided with a drain hole 1, and two sides of the drain hole 1 are provided with fiber covers 2. The fiber cover 2 is a grid-shaped polyethylene fiber cover, and can effectively prevent the water drainage holes from being blocked.

The upper extension section 3 of each component is provided with a first threaded hole 5, the middle extension section 4 is provided with a second threaded hole 15, steel cylinders with internal threads are arranged in the first threaded hole 5 and the second threaded hole 15, the first threaded hole 5 of the upper extension section of one component is in lap joint with the second threaded hole 15 of the middle extension section of the other component, the lap joint is fixed through a bolt 6, and a water supply and drainage channel 7 is arranged below the lap joint of the two threaded holes.

It needs to be further explained that an additional platform 8 is arranged on the outer side of the grating, an anchor rod hole 9 is formed in the additional platform, a smooth steel circular column is arranged in the anchor rod hole 9, and an anchor rod 10 is inserted into the anchor rod hole 9 for supporting.

The high slope is firstly graded and released. Spraying low-alkali concrete to the slope, presetting anchor rod holes in a section with deep soil layer, mainly spraying low-alkali concrete in a section with shallow soil layer, and also setting the anchor rod holes according to requirements.

Firstly, aligning different extension sections of two identical components, ensuring that a first threaded hole 5 and a second threaded hole 15 of the two components are aligned after aligning, and screwing a bolt 6 into the first threaded hole 5 and the second threaded hole 15 so as to realize the connection of the two components;

after the combined body is screwed down, the combined body is connected to other components and screwed down, then a new component is connected with the head side and the tail side of the new combined body, so that four grid chambers with mutually engaged components are formed, the four components are connected to form one grid chamber, and one grid chamber is fixed by four bolts.

The cells are now diamond or square and unstable, and therefore require anchors to achieve stability.

After anchor rod holes are pre-drilled on the slope surface and hole cleaning is completed, the connected grid chambers are placed to the slope bottom, then anchor rods 10 are inserted into the anchor rod holes 9 and are inserted into the slope body to a certain depth to fix the grid chambers, in the embodiment of the application, three anchor rod holes are formed in each side, and 12 anchor rods are needed in total. Then, the new grid chamber extension section 3 is combined with the grid chamber extension section 3 fixed previously, and after the combination, the new grid chamber is fixed by using an anchor rod, and finally, the slope surface is distributed in the grid chamber.

After the grid chambers are fully distributed, water supply and drainage pipes can be arranged in the reserved water supply and drainage channels 7 according to local climate, and the ecological bags are paved in the grid chambers along the slope. And injecting low-alkali concrete into the grid through a small guide pipe after the steps are finished, so that consolidation of soil around the grid is realized, then planting plants in the grid chamber, placing ecological bags or filling foreign soil in the grid chamber aiming at the section with more stones, and then planting grass.

The chamber main body can be recycled after the plants grow. Firstly, the bolts lapped between the cells are screwed out from the top of the slope, the cells on the slope are sequentially dismantled, and then the bolts bolted in the same cell are screwed out, so that the original component can be restored, and the cyclic utilization is realized.
