Description

A kind of punishment device for non-excavation type execavated rockmass pit disease

Technical field

This utility model belongs to side slope Treating technology field, particularly to a kind of punishment device for non-excavation type execavated rockmass pit disease.

Background technology

Execavated rockmass in use, Chang Yinwei rain drop erosion, climate change and other reasons, cause the diseases such as domatic peeling, form the pit that destructiveness is different. Punishment to execavated rockmass pit, generally has following two mode: when pit scope is less, or when the degree of depth is shallower, do not affect the stability of side slope, now disregard at present; When pit scope is relatively big, or when the degree of depth is deeper, then again brush slope, after reaching certain ratio of slope, carry out domatic grass planting or the protection of other masonries.

First kind of way problematically, which is a kind of comparatively passive Treatment Scheme, when pit is disregarded, disease can develop further under severe natural environment, thus causing that even more serious disease occurs. Protecting according to after again brushing slope, often due to brush slope scope is relatively big, the mode of heavy excavation causes the destruction to original soil body and protection method, also necessarily causes higher cost. If side slope produces pit disease again behind brush slope, deal with extremely inconvenience.

Summary of the invention

For overcoming above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of punishment device for non-excavation type execavated rockmass pit disease, has the advantages that simple in construction, cost are low, easy to use.

For achieving the above object, the technical solution adopted in the utility model is: a kind of punishment device for non-excavation type execavated rockmass pit disease, includes the spacer bar mesh sheet being located at bottom pit, and the bottom of spacer bar mesh sheet is implanted in the soil body bottom pit; Spacer bar mesh sheet arranges code and builds bag; From lower to upper one layer of spacer bar is set every 4-5 layer and implants the support bottom pit; Undermost spacer bar adopts HRB335 level �� 2020cm reinforced mesh.

The described code outside pit that is located at builds bag employing plant biological bag.

Described code is built bag and is adopted rubble bag or earth bag.

It is be more than or equal to 1 meter that the length of pit soil body part is implanted in the bottom of described spacer bar mesh sheet.

The spacer bar of described centrally located layer position adopts HRB335 level �� 1220cm.

Arranging drain pipe in described pit, drain pipe is divided into draining section, the section of intercepting water, outdrill section; Drain pipe adopts HDPE corrugated tube with holes.

The beneficial effects of the utility model are:

This method adopts no-dig technique mode that the pit that excavation is domatic is punished, earth bag is built by code after slope stability district implants spacer bar mesh sheet, effectively it is filled with domatic pit region, and by arranging drain pipe, the slope internal water of pit is drawn domatic, then carry out breaking dibbling grass after domatic outermost code builds plant biological bag, recover domatic greening, thus ensureing domatic attractive in appearance and stable. This method is simple and easy to do, it is to avoid to domatic excavation, effectively increases slope stability, has recovered slope greening, substantially increases work effectiveness; Have the advantages that simple in construction, cost are low, easy to use.

Detailed description of the invention

Below in conjunction with accompanying drawing, structural principle of the present utility model and operation principle are described in further detail.

Referring to Fig. 1, a kind of punishment device for non-excavation type execavated rockmass pit disease, including the spacer bar mesh sheet 1 being located at bottom pit, the bottom of spacer bar mesh sheet 1 is implanted in the soil body bottom pit; Spacer bar mesh sheet arranges code and builds bag 2; From lower to upper one layer of spacer bar is set every 4-5 layer and implants the support 3 bottom pit; Undermost spacer bar adopts HRB335 level �� 2020cm reinforced mesh.

Described code is built bag and is adopted rubble bag or earth bag.

Code is built earth bag and is adopted straw bag, gunnysack, Glass Fibre Bag or the packed mound code of non-woven fabrics. Bag should load the good pellet of the water penetration such as coarse sand or boulder and cobble. Soil loading amount is the 1/2-2/3 of earth bag capacity, and bag mouth should be sewed up. The soil containing the foreign material such as tree root, fragment of brick or organic matter is not allowed in earth material.

The bottom of described spacer bar mesh sheet 1 is implanted the length of pit soil body part and is not less than 1 meter.

Described drain pipe pierces portion in the body of slope according to soil property, hydrologic regime, and caliber is 100mm. The spacer bar of described centrally located layer position adopts HRB335 level �� 1220cm. Bore diameter is 110mm, and drain pipe adopts HDPE corrugated tube with holes.

Referring to Fig. 3, arranging drain pipe 5 in described pit, drain pipe is divided into draining section, the section of intercepting water, outdrill section; Drain pipe adopts HDPE corrugated tube with holes. In described drain pipe draining section, 1-3m does not punch, punching, diameter 10mm, longitudinal pitch 150mm in the section of intercepting water. The described HDPE corrugated tube with holes permeable geotextiles of outsourcing, geotextiles adopts the standard of 400g/m.

Operation principle of the present utility model is:

After being cleared up at pit interface, implanting spacer bar mesh sheet bottom pit, longitudinal reinforcement should stretch into the stable soil body and be not less than 1 meter. Then in spacer bar mesh sheet, code builds earth bag, if side slope is stone matter, can build rubble bag by code in spacer bar mesh sheet. Scope according to pit disease, can arrange one layer of spacer bar every 4-5 layer earth bag. When rock side-slope adopts rubble bag, one layer of spacer bar is set every layer 2-3 rubble bag;And by arranging drain pipe, pit slope internal water is drawn domatic; The outermost earth bag of pit adopts plant biological bag, adopts modes such as breaking dibbling grass, recovers slope greening.

Operating process of the present utility model is:

1) when execavated rockmass is rock side-slope:

Finishing side slope �� measurement, unwrapping wire �� pore-forming �� joint bar �� slip casting �� code build rubble bag (plant biological bag) �� maintenance

2) when execavated rockmass is soil-slope:

Finishing side slope �� measurement, unwrapping wire �� pore-forming �� joint bar �� code build earth bag (plant biological bag) �� maintenance

Drain pipe adopts quincunx setting, spacing 1.0m, can do suitable adjustment according to pit damage envelope and slope body soil property, hydrologic regime; Bottom spacer bar adopts HRB335 level �� 2020cm reinforced mesh, position, intermediate layer reinforced mesh �� 1220cm, during soil-slope boring, forbids to pour water, it is possible to directly squeeze into reinforcing bar. Rock side slope can adopt the method that slip casting anchors. Grouting pressure adopts 0.4MPa, ratio of mud 0.45-0.5 neat slurry, and cement adopts P.O.32.5.
