Description
Technical field
The present invention relates to rapidly solidified construction equipment of tidal land mud and job practices, handle the consolidation construction method of heavy shallow-layer and the long-pending silt soil of deep layer, particularly the fixed construction of blowing-filling sludge again on the deep ultra-soft clay foundation of deposition.
Background technology
Acceleration propelling along with industrialization and urbanization, coastal area construction land demand surge, required sand, the building stones of backfill also reduce gradually, National Bureau of Oceanography issued " national scientific and technological Xinghai County planning outline (2008-2015) " in 2008, mention in the literary composition: " correlation technique of artificial seashore construction mode of ecoscape formula such as integrated application beach is enclosed and cultivated, strand highway network, river mouth and low-lying bank section seawall and the scientific utilization in coastline advances great environmental engineering, the marine city construction of livable type." rational exploitation and utilization beach resource, utilize ocean beach mud as backfilling material, be the important channel that solves the shortage of construction land material resources, protection sandy beach and reduce exploitation of stone, also be the effective measures that advance the economic dispatch interlock of sea, land.
How to utilize beach mud just to become the key issue of developing the ocean beach as enclosing and cultivating backfilling material, the now general method that adopts is to utilize the sand cushion draining processing that combines with vacuum preloading, deep layer takes plastic draining board to handle, but these processing methods also just solve the soil body self discharging consolidation, for the moment also be difficult to improve the soil body self intensity, and cost is relatively more expensive, handles the requirement that the back bearing capacity still is difficult to satisfy the construction equipment construction ability.In recent years, the curing compound technology is used in roadbed, treatment of soft foundation, but because silt soft base plant equipment can't be walked, deep mud does not also have Construction Operating Machinery equipment at present, and shallow-layer also just digs out mud, land be cured agent stir mixed after, carry out backfill again, but treating capacity is smaller, not only efficient is low, and the cost height, and remote large-area hydraulic reclamation engineering can't be implemented at all.
So a kind of consolidating agent that can directly carry out on deep silt soft base stirs the plant equipment of construction and the invention of construction technology, development, the propelling coastal area economic prosperity that promotes the cause of enclosing and cultivating had great significance.
Summary of the invention
In order to overcome the construction difficult problem that the silt consolidation agent can not directly be stirred at the silt soft base, the present invention develops rapidly solidified construction equipment of tidal land mud and job practices, this equipment can not only directly be coated with on the face at mud and walk, and directly finishes stirring work when adding consolidating agent in mud.
The technical solution adopted for the present invention to solve the technical problems is:
The rapidly solidified construction equipment of tidal land mud is provided with running gear, high pressure feedstock induction system, rotation rotary jet stirring system, dual power drive system composition that mud is coated with face.High pressure feedstock induction system output connects stirring system, and stirring system is fixed on mud and is coated with on the running gear of face, and running gear is installed dual power drive system.Curing compound is delivered to stirring system by the high pressure feedstock induction system, rotate the rotary jet stirring system that adds high pressure consolidating agent is fully mixed stirring with the ultra-soft basis, under the effect of dual power drive system, the beach running gear is worked continuously on soft base according to construction process, finally realizes the rapidly solidified processing of soft base.The work of this equipment: one, mud is coated with the running gear of face, utilizes 2 float type worm propellers, and traction and buoyancy are provided simultaneously, and screw rod adopts the despining Archimedes spiral.The cylinder float structure of propeller self provides the buoyancy of equipment, can reduce the grounding pressure of the face that is coated with mud; Angle of rake despining Archimedes spiral structure can reduce the adhesion stress with mud, and augmented thruster drives thrust, the antiskid commentaries on classics performance of raising plant equipment; The power of running gear is furnished with two cover hydraulic moving motors.Two, high pressure feedstock induction system, curing compound are carried and are adopted slurry agent high-pressure plunger pump to carry, and the high-pressure rotary-spray distributing valve is installed on the mixing plant, and distributing valve is dispensed to each cyclone nozzle with fixed slurry agent high pressure again, is ejected into to stir in the mud under the effect of high pressure; Booster pump and electronic flow controller are installed on the distributing valve, are controlled and adjust the feed flow of consolidating agent.Three, the stirring system of consolidating agent and mud, agitator adopts at a slow speed, and machinery rotates the rotary jet stirring that adds high pressure, mechanical stirring equipment adopts the portal framed structure multihead stirrer, and agitator can freely tilt under the impetus of hydraulic cylinder, freely promote, and can make agitator be in best stirring angle; Agitator strand head adopts φ 80 bolt arrangements, mud is spun upside down in a strand scope mix and stir; Shaft adopts hollow structure, as the transfer passage of medicament, the high-pressure rotary-spray head is installed on the stirring-head, and (pressure is controlled at 1.5mp) realizes the consolidating agent high-pressure rotary-spray under the effect of high pressure, thereby reaches the effect that stirs fast.Four, equipment dynamic configuration-system adopts dual power drive system, is active force with the diesel-driven generator, and the apolegamy hydraulic power unit is secondary power, and adopting hydraulic power unit is that secondary power can reduce whole weight greatly.
The construction technology of plant equipment: according to the moisture content and the engine request of engineering mud, determine that (tidal land silting moisture content is 60%～150% to consolidating agent admixture ratio, corresponding consolidating agent blending ratio is 10%～20%, soil property is good or contain arenaceous sediment mud, construction can reduce the blending ratio of consolidating agent, be generally 5%～15%), execution conditions according to the engineering fed distance, determine the water/binder ratio (the general control 0.5～2 of the water/binder ratio of curing compound slurries) of curing compound, determine each equipment running parameter (angle of rake speed of travel according to admixture ratio and water/binder ratio, the lifting velocity of agitator, the feed flow of slurries).Slurries are delivered to stirring system by high-pressure plunger pump, in conjunction with the high pressure distributing valve consolidating agent is injected in the mud, in the equipment walking, stir operation, finish the correspondence blending and stirring of consolidating agent, utilize the electronic flow controller to carry out the control of slurries blending ratio, finally realize the processing of consolidating agent the silt soft base.
The beneficial effect that the present invention has is: the curing compound by the soft base in invention seabeach stirs construction equipment and technology, realized that the silt soft base utilizes consolidating agent to carry out rapidly solidified processing, construction is simple, high efficiency, the processing degree of depth are big, and the treatment of soft foundation cost reduces greatly.
