Abstract
The utility model discloses an auxiliary sleeve pipe injection system, which consists of a high-pressure water pump, a water flushing pipe and a spray nozzle arranged at the end part, and is characterized in that the spray nozzle adopts a one-way valve. The auxiliary sleeve pipe injection system has the advantages that a cutting effect generated on a soil layer below the end part of a sleeve pipe and a flushing perturbation effect generated on soil bodies around the sleeve pipe by water flushing are utilized, and the resistance received by the sleeve pipe can be effectively reduced, so the injection efficiency of the sleeve pipe is improved, and through the arrangement of the one-way valve, the mud is ensured not to enter a water pipe when the water flushing is not carried out.
Description
Technical field
The utility model relates to constructive technology of squeezed dense sand under water, particularly a kind of sleeve pipe injection accessory system.
Background technology
Sand compaction pile is a kind of ground stabilization new technology under water, and it is by vibratory equipment and tube chamber supercharging device sand to be forced to be pressed under water in the soft foundation on the sand pile ship, through vibration pipe-drawing, return, compacted hole enlargement, form sand compaction pile.By the displacement of sand compaction pile, compacted, drainage, can increase foundation strength, accelerate ground consolidation, reduce the works sedimentation, improve the anti-liquefying power of ground.The scope of application of sand compaction pile is extensive under water, can be applicable to the ground stabilization of nearly all soil properties such as sandy soil, cohesive soil, organic soil is handled.Compare the density height of sand compaction pile pile body with common sand pile, the replacement ratio of reinforcing can reach 60～70%.Characteristics such as sand compaction pile has short construction period under water, consolidation effect is obvious, and the operation controllability is good, the advantage uniqueness is highly suitable for the ground base enforcement of engineerings such as off-lying sea man-made island, mole, shore protection, harbour.
The sandy pile construction middle sleeve is that sand is poured into passage in the soil, in the treatment of soft foundation engineering practice, finds to run into hard sand interlayer through regular meeting in soft foundation.Sleeve pipe efficiency of construction in the process that runs through hard sand interlayer is very low.
The utility model content
For addressing the above problem, the utility model provides a kind of sleeve pipe injection accessory system that is arranged on the sand pile ship according to the principle of jetted pile, to improve sleeve pipe injection efficient.
To achieve these goals, the utility model adopts following technical scheme:
Sleeve pipe injection accessory system is made up of high-pressure hydraulic pump, jet water spout and the nozzle that is arranged on the end, it is characterized in that described nozzle adopts one way valve.
The dominant mechanism of auxiliary pile sinking is the dissection utilizing water to dash the following soil layer of cannula tip is produced and washes away perturbation action to what the sleeve pipe surrounding soil produced.Adopt technique scheme, can effectively reduce the suffered resistance of sleeve pipe, thereby improve sleeve pipe injection efficient, make in the easier injection ground of sleeve pipe.
Description of drawings
Fig. 1 is the structural representation of one way valve of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth embodiment of the present utility model.
Sleeve pipe injection accessory system of the present utility model, by as sleeve pipe injection accessory system power source high-pressure hydraulic pump, jet water spout is formed with the nozzle that is arranged on the end, the output hydraulic pressure of high-pressure hydraulic pump is 14MPa, jet water spout adopts the hard water pipe of diameter 19mm, described nozzle adopts one way valve, as shown in Figure 1, described one way valve adopts the spring one way valve, comprise valve pocket 100, spool 200, spring 300 and spring base 400, valve pocket 100 both ends opens, spool 200 is positioned at valve pocket 100 inside, spool 200 sides have radial hole 201, have axial hole 202, one springs 300 on axially to be located in the axial hole 202, spring one end is against on the spring base 400 that is fixed in valve pocket 100 right-end openings, and the other end is against on the valve seat of valve pocket 100 left end opening parts spool 200.
Water under high pressure overcomes spring 300 and acts on power on the spool 200 when the opening of valve body left end flows into, spool 200 is moved right, and opens valve port, and flows out from the opening of valve body right-hand member by the radial hole 201 on the spool 200, axial hole 202; When water when the opening of valve body right-hand member flows into, the pressure of water and spring force make spool 200 be pressed on the valve seat together, and valve port is closed, water is not had dispel by, mud does not enter in the water pipe when having guaranteed not wash by water.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
