Abstract
The invention relates to a support structure for ribbed tube of water drainage itself. The ribbed tube of water drainage itself inserts into the soil slope and soil blocking face-layer is covered outside of the soil slope. The soil blocking face-layer is connected with the ribbed tube of water drainage itself. The total structure is constituted by the ribbed tube of water drainage itself and the soil blocking face-layer. The ribbed tube of water drainage itself mentioned above is hollow tube. Drainage holes are distributed on the wall of hollow tube and porous material with seepage and anti-flowing soil is filled in the hollow tube. The soil blocking face layer is reinforced concrete face-layer, pure concrete face-layer, steel wire net layer or woodblock facing layer. In the invention water drainage performance is integrated with the reinforced performance together so as to discharge the water in the soil at the back of support effectively or adjust the water content in the soil, improve the effective stress in soil, modify the quality and state of soil and improve the stability of soil. In the invention the construction speed is quick. It can be return to reuse and decrease the pollution to environment. The construction safety is improved. The construction period is shortened and the cost is decreased.
Description
(1) technical field
The invention belongs to the geotechnical engineering technical field, the supporting and protection structure and the method thereof of particularly a kind of foundation ditch and side slope.
(2) background technology
In the existing geotechnical engineering, foundation ditch and side slope supporting and protection structure commonly used is retaining wall, slope protection pile (piling bar, concrete pile) or diaphragm wall.Said structure carries out draining by measures such as gutter are set separately, and supporting is what to separate with draining, especially is difficult to effectively draining be carried out in upper strata soil body backwater, if soil body backwater can not will be buried the hidden danger that foundation ditch and side slope are subsided by effective drainage.Above-mentioned traditional structure long construction period, the construction costs height, and when running into sandy gravel, be difficult to construction.Owing to reasons such as construction technologies, also be not suitable for the effective ways of deep layers such as foundation ditch, side slope at present from draining and perched water.
(3) summary of the invention
The present invention proposes a kind of self-draining reinforced pipe supporting structure (Reinforced Drainage Tube Structure, under be called for short RDTS) and job practices, solve the problem of discharge supporting behind inside soil body water in supporting, and solve the problem that further improves safety of construction, further reduction of erection time, reduction cost.
Technical scheme of the present invention: this self-draining reinforced pipe, be stock shape, it is characterized in that: self-draining reinforced pipe is a hollow section, the tube wall of hollow section is distributed with drain hole.
Above-mentioned self-draining reinforced pipe is that front end is the metal tube, non-metallic pipe of tip, above-mentioned one or more compound tube, the inside of pipe is plugged with the porous material of the anti-stream soil of one or more infiltrations, and the porous material of the anti-stream soil of above-mentioned infiltration is porous plastics, cellosilk mass, sponge, graded soil, sandstone, cinder, dump slag.
The caliber of above-mentioned self-draining reinforced pipe is 4mm～3000mm, and the aperture of drain hole is 0.1mm～1000mm, and the profile of above-mentioned self-draining reinforced pipe is uniform section pipe or varying cross-section duct.
The self-draining reinforced pipe supporting structure of the above-mentioned self-draining reinforced pipe of this application is characterized in that: self-draining reinforced pipe is inserted at interval form self-draining reinforced pipe supporting structure in the upper side slope.
The side slope outside of the above-mentioned soil body is covered with the native surface layer of retaining, keeping off native surface layer links to each other with self-draining reinforced pipe, and formation overall structure, keeping off native surface layer is steel concrete, reinforced concrete mortar, reinforced concrete slurry, concrete, cement mortar, cement paste, gauze wire cloth, steel mesh reinforcement, plastic wire, plank, above-mentioned one or more combination.
The job practices of above-mentioned self-draining reinforced pipe supporting structure is characterized in that job practices has following steps:
Step 1: determine position, reinforcement hole at the side slope place of the soil body;
Step 2: self-draining reinforced pipe is inserted in the soil body in position, reinforcement hole;
Step 3: the native surface layer of retaining is done in the side slope outside at the soil body, keeps off native surface layer and is connected with self-draining reinforced pipe;
Step 4: repeat 1～4 step, finish until supporting.
In step 1 and 2, position, the reinforcement hole pore-forming of determining at the side slope place of the soil body, self-draining reinforced pipe insert method in the soil body be send into, hammering is gone into, ram into or static pressure method insert the soil body.
After step 4, apply the prestressing force step, self-draining reinforced pipe is divided into anchoring section and free section two parts, has 3 kinds of methods can form the free section of self-draining reinforced pipe, 1. realizes with the variable cross-section self-draining reinforced pipe, the heavy in section part is an anchoring section, and small bore partly is free section; On pipe the outsourcing plastics, be coated with sliding agent, or above-mentioned combination forms free section part; Method 1 and 2 be combined to form free section part, the free section and the locking of stretch-draw self-draining reinforced pipe have promptly applied prestressing force.
In step 4, can be at the outer mouth of pipe edge of self-draining reinforced pipe fixing drainage by suction device, carry out drainage by suction.
Following steps are arranged after step 4:
Step 5: after predetermined function is finished in supporting, tube drawing;
Step 6: filling perforation;
Step 7: backfill;
Step 8: repeat 6～7 operations, until pit backfill to design elevation.
Beneficial effect: the present invention with formed an integral body by the supporting soil body, help the discharge of soil body deep water and perched water, help adjusting the water content of inside soil body, help improving stability by the supporting slope soil.The present invention integrates draining and reinforcement function, has changed the seepage direction of water in soil, can effectively discharge the supporting water of inside soil body behind, improves effective stress in the soil, changes the character and the state of soil, improves the stability of the soil body.Speed of application of the present invention is fast, can recycling, reduce pollution to environment, and improve safety of construction, can the reduction of erection time, reduce cost.Self-draining reinforced pipe supporting structure of the present invention both can apply prestressing force, also can not apply prestressing force, thereby can either be used to prevent side slope or foundation ditch shallow-layer to slide, and the deep layer that can be used in prevention side slope or foundation ditch is again slided.The present invention can adopt the preexisting hole technology to construct applicable to multiple job practices, the construction of static pressure technology, but also hammering method construction.The present invention can be adapted to multiple geological condition, as: clay, silt, sand-pebble etc.
