Abstract
The invention discloses a soil mass supporting structure and a construction method thereof. The soil mass supporting structure comprises multiple rigid stiffened piles in rows, and each rigid stiffened pile is provided with a rotary jet mixing anchor rod. The construction method comprises the following steps of: mounting the rigid stiffened piles between ground and a pit base, arranging capping beams at the tops of the rigid stiffened piles, and arranging middle beams at the middle parts of the rigid stiffened piles; and forming rotary jet mixing anchor rods on the capping beams and the middle beams through high-pressure grouting rotary-jetting and grouting mixing, wherein the rotary jet mixing anchor rods are connected with the capping beams and the middle beams in a locking manner, and reinforcing ribs are arranged in the rotary jet mixing anchor rods. According to the construction method disclosed by the invention, the rotary jet mixing anchor rods take the place of inner supports, thus drilling, grouting and anchoring are finished in one step, the diameters of the anchor rods are large, the anchorage force is large, and the problem that a conventional anchor rod can not be constructed in a loose sand layer and a sludge soft soil layer can be solved.
Description
Technical field
The present invention relates to a kind of retaining wall structure and job practices thereof.
Background technology
In some soft clay area; Like China economically developed riverine, coastal, along the river Shenyang, Tianjin, Shanghai, Guangzhou and Yangtze River Delta, Delta of the Pearl River area; Because the soil is soft, in the foundation construction of building, need before excavation pit, make retaining wall.
Because loose layer of sand and muddy soft soil; Conventional anchor pole the weak soil layer as thumbnail in contact pin generally can't use; Cause that the abundant sand gravel layer drilling and forming hole of water content is difficult, the dowel of anchor pole is difficult to insert, have only passive employing cost high, long in time limit, to the city have the concrete underground continuous wall of mud contamination add in the supporting and protection structure mode of support construct this job practices complex procedures; Time is long, and cost is high.
Summary of the invention
The technical issues that need to address of the present invention just are to overcome the defective of prior art; A kind of retaining wall structure and job practices thereof are provided; It is got for interior support with the rotary jet stirring anchor pole; Realized creeping into, slip casting, down dowel is once accomplished, bolt diameter is big, the anchor pulling force is high, has solved the difficult problem that conventional anchor pole can't be constructed at loose sand silt soft soil layer again.
For addressing the above problem, the present invention adopts following technical scheme:
The invention provides a kind of retaining wall structure, said retaining wall structure comprises many rigidity strength types stake in a row, in the stake of said rigidity strength type the rotary jet stirring anchor pole is installed.
The stake of said rigidity strength type is concrete boring stake, steel H pile, steel sheet pile or timber.
The anchor pole that forms is stirred in said rotary jet stirring anchor pole forms for the high-pressure slip-casting churning, slip casting.
Be provided with reinforcing rib in the said rotary jet stirring anchor pole.
Reinforcing rib muscle in the said rotary jet stirring anchor pole is reinforcing bar, steel wire or steel pipe.
Said rotary jet stirring bolt grouting material is a cement grout.
Said rigidity strength type stake top is provided with capping beam, and rigidity strength type stake middle part is provided with waist rail, and said rotary jet stirring anchor pole connects locking with capping beam and waist rail.
The stake of said rigidity strength type is installed on ground and cheats at the end.
The present invention discloses a kind of job practices of retaining wall structure, said method comprises the following steps:
1), on ground and hole the stake of rigidity strength type is installed at the end, rigidity strength type stake top is provided with capping beam, and rigidity strength type stake middle part is provided with waist rail;
2), on capping beam and waist rail, stir through high-pressure slip-casting churning, slip casting and to form the rotary jet stirring anchor pole, said rotary jet stirring anchor pole connects locking with capping beam and waist rail, is provided with reinforcing rib in the rotary jet stirring anchor pole.
The present invention gets for interior support with the rotary jet stirring anchor pole; Do not need during because of the rotary jet stirring anchor bolt construction first retaining wall creep into the anti-pore-forming that moves in circles, in pore-forming path hole joint bar, in unsafe again technologies of complicacy such as following Grouting Pipe perfusion mortars; The present invention has realized creeping into, slip casting, down dowel is once accomplished; Bolt diameter is big, the anchor pulling force is high, has solved the difficult problem that conventional anchor pole can't be constructed at loose sand silt soft soil layer again.In replacing, supports this patent major diameter anchor pole required a large amount of columns and crossbeam; Cheat interior spaciousness, can save wide variety of materials and duration; Job practices is simple, cost is low, the duration is fast, pollution is few, digs fortune for the later stage earthwork and basement structure construction has been created good space and convenient.
