Description
Technical field：
It the utility model is related to base board technical field, and in particular to one kind is applied to reusable group of soft soil foundation
Box-like base board.
Background technology：
Soft soil foundation is because inhomogeneities is in notable difference in plane and vertical direction, especially in the knot of flocculence
Structure deposit, when undisturbed soil is not damaged often with certain structural strength, but destroyed once disturbance, structure, intensity is rapid
Diluted state is reduced or quickly becomes, so after the vibrated dynamic load of soft soil foundation, phenomena such as being also easy to produce lateral sliding, settle, and
In general base board will cause platform to sink on such soft soil foundation after long-term use, certain danger be present.In reality
In operation, staff general is again simply to be attached two pieces of adjacent base boards using iron chains, and base board it
Between can form gap, when base board causes to settle and shifted because of unbalance stress, gap is increasing, to on-site personnel
Personal safety cause a hidden trouble.
Utility model content：
In view of the above-mentioned problems, problem to be solved in the utility model is to provide, a kind of to be applied to soft soil foundation reusable
Combined type base board.
To solve the above problems, the technical solution adopted in the utility model is, one kind makes suitable for soft soil foundation is repeatable
Combined type base board, including base board 1, high-strength bolt 2, bottom surface liner plate 3, post jacking formula screw-thread steel pile tube 4, its feature
It is：Base board is connected by high-strength bolt, has bottom surface liner plate under junction, and post jacking formula screw-thread steel is used on soft foundation
Pile tube is reinforced.
The post jacking formula screw-thread steel pile tube grouting port is located at stake top side, a diameter of 25mm of grouting port, a length of 100mm,
Screw-thread steel pile tube diameter 0.6m, pile body long 2-3m, pile top 0.4m, the spacing along base board length direction are 1.4m.
The post jacking formula screw-thread steel pile tube is evenly arranged two in the width direction in the junction of two pieces of adjacent base boards.
The post jacking formula screw-thread steel pile tube pile top is furnished with bleeding hole 2-3.
The base board is made of stainless steel material.
The base board is the thick 20-30mm long checkered plates of pressure, monolithic base board long 2m, wide 4m.
The bottom surface liner plate be thick 10-20mm plain plate, the monolithic bottom surface long 0.8m of liner plate, wide 4m.
The high-strength bolt is uniformly arranged three groups, every group two along every piece of base board both sides.
The high-strength bolt is process using No. 45 steel of 10.9 strength grades.
The utility model is simple in construction, using the post jacking formula screw-thread steel pile tube soil mass consolidation inserted on soft foundation,
Then base board is connected with high-strength bolt, had both ensure that normal use of the base board on soft foundation, and turn avoid because of stress
Settle and shift caused by inequality, base board can be recycled normally after hours.Effect is good, rational in infrastructure and section
Learn economical.
Brief description of the drawings：
Fig. 1 is the utility model overall structure diagram.
Fig. 2 is the integrally-built top view of the utility model.
Wherein 1. base boards, 2. high-strength bolts, 3. bottom surface liner plates, 4. post jacking formula screw-thread steel pile tubes, 5. screw threads, 6. bleeding
Hole, 7. grouting ports.
Embodiment：
With reference to accompanying drawing, the utility model structure is described further.
One kind is applied to the reusable combined type base board of soft soil foundation, including base board 1, high-strength bolt 2, bottom surface
Liner plate 3, post jacking formula screw-thread steel pile tube 4, it is characterized in that：Base board 1 is connected by high-strength bolt 2, has bottom surface under junction
Liner plate 3, reinforced on soft foundation using post jacking formula screw-thread steel pile tube 4.
First post jacking formula screw-thread steel pile tube 4 is screwed similar to the principle of the turn of the screw using mechanism and is deep into foundation soil
1.5-2.5m, a small amount of clear water is injected by grouting port 7 during screwing, soften soil layer and reduce end-resistance.Post jacking formula spiral shell
The screw thread 5 being uniformly arranged on the pile body and pile top of line steel-pipe pile 4, the stake is formed more obvious mechanical type with Soil Interface and sting
Close, the reason of " screw is more firm than nail " in general knowledge is applied in steel-pipe pile.After the pile sinking of post jacking formula screw-thread steel pile tube 4
It is 0.5 that the grouting port 7 of stake top, which injects ratio,:1 cement mortar adds the mixed serum of micro-expanding agent, and stake holes is reinforced by bleeding hole 6
Surrounding soil.
After treating that post jacking formula screw-thread steel pile tube 4 squeezes into ground successively and all pile sinking is stable, bottom surface liner plate 3 is spread respectively
It is located on post jacking formula screw-thread steel pile tube 4, the debris that should be first rebuild before bottom surface liner plate is laid on cleaning road bed ensures road
Basal plane is smooth.First piece of base board 1 is hung into specified location using crane to be laid, it is pre- on base board 1 and bottom surface liner plate 3
Hole has been stayed, and then base board 1 and bottom surface liner plate 3 being tightened against hole with high-strength bolt 2 must not firmly loosen, then successively
Lay remaining base board.
Further, spacing of the post jacking formula screw-thread steel pile tube 4 along base board length direction is 1.4m.
