Abstract
The utility model relates to the equipment of soft foundation treating engineering. The main characteristic is that a hinging device is an inner hinging type structure which is a hinging pin axle is supported by a pin axle hole whose inner portion and outer portion are sheathed into integration along the axial direction without easy to be exposed out. The defects that the outer hinging type structure is easy to be damaged by the blocking of mud or other foreign matter because the hinging device is exposed out and the gap between a hole forming wall and a sand bag is oversize are overcome. The utility model can be widely used for the treating engineering of using a bag loading sand well to reinforce the soft foundation.
Description
The utility model belongs to subgrade treatment project equipment class.
The subgrade of sand wick reinforcing at present technology is widely used in the various engineering constructions, and so-called " sand " is meant the granular substance of good water permeability in fact, and the bag of sand pocket is to have the material of enough toughness to make again with ventilative, good water permeability.
General job practices is with penetrating power to the stake pipe, make it reach underground desired depth, the sand pocket that will install sand again drops in the stake pipe, sand pocket stays in underground when the stake pipe is extracted, only sack is basseted for one section, the water of subgrade overflows by sand after entering sand pocket, thereby subgrade is reinforced.Silt particle does not enter the stake pipe in the stake pipe sinking process in order to make, and sand pocket can stay in underground when extracting the stake pipe, so in stake pipe lower end the end cap device is housed.The clear 47-37572 of Japan Patent, what clear 57-48013 introduced is the movable end cover device, stake pipe end cap in sinking to underground process is closed during use, end cap is opened when extracting, and sand pocket stays in underground, and end cap is opened freely, its hinge is outer hinge formula structure, outside promptly hinge is exposed to.The shortcoming of this form of structure is: 1. silt particle foreign material etc. easily block the activity of hinge, as run into hinge pin such as hard thing and base plate fragile, and on-the-spotly change inconvenience.2. since outer hinge formula structure to make into hole area big, the gap is big between hole wall and sand pocket, and the ground subsequent settlement is big when causing precompressed, and becomes the also increase thereupon of the big penetration resistance of hole area, and is unfavorable in engineering.
The utility model is that it has overcome above-mentioned shortcoming to the improvement of clear 57-48013 stake pipe end-cap device.
The utility model is a pipe end-cap device, comprise end cap (1), hinge, it is characterized in that hinge is interior hinge formula structure, promptly have interior cover (6), overcoat (4), joint pin axis hole along its axially a part (10) on interior cover (6), another part (12) is on overcoat (4), and the part that puts outward is a slotted hole; Inside and outside putting has groove (11), (2) that connect end cap (1) and hinge pin (3), and hinge pin (3) is passed end cap pin shaft hole suitable for reading (13) herein; Link with screw thread between the inside and outside cover, bearing pin is embedded in the pin shaft hole; The overcoat top has locknut (5) that overcoat is compressed.Outside such form of structure makes that whole hinge means is not exposed to, be difficult for contaminated foreign material in the work progress and block, be difficult for being damaged by hard thing, even overcoat needs to change because of wearing and tearing, owing to adopted the spiral marking connection mode, thereby on-the-spot only the replacing need 1～2 minute, and be very convenient.Because interior chain type makes that the gap reduces greatly between pore-forming hole wall and sand pocket, stake pipe penetration resistance also reduces, and pre-seasonable ground subsequent settlement reduces, and has improved the efficient and the quality of soft groundsill reinforcing engineering.
From trial state see end cap with four taper flapper-types (1) for well, this moment, each flap valve need be opened tongue and groove (9), made the abundant interlock of adjacent flap valve.Certainly also can make veneer or other forms.
Introduce the embodiment of this device below.This is a kind of four taper flapper-type stake pipe end-cap devices, as shown in Figure 1.
With interior cover (6), overcoat (4), end cap (1), hinge pin (3) locknut component such as (5) are processed appropriate, hinge pin is passed end cap pin shaft hole suitable for reading (13) and adopted the stationary fit mode that it is integral, again interior cover is assembled with it, it is the joint pin axis hole of cover in hinge pin places, overcoat is inserted in from interior cover top screws, locknut also is inserted in locking jacket from the top.In cover with stake pipe minor details (7) identical internal diameter is arranged, a stake pipe minor details lower end is welded with sleeve pipe (8), sleeve pipe have internal thread just in time to match with the external screw thread of interior cover and the below a section an of pipe range put in just in time being enclosed within, can use after screwing.So promptly by sleeve pipe minor details being managed in stake is associated in interior cover and also just stake is managed minor details and be associated in whole stake pipe end-cap device.This device is used in sand pocket φ 70, and the sand wick of stake pipe φ 86 is reinforced soft-foundation engineering and produced effects obviously.
Because the drawback that outer hinge formula structure exists, at present domestic have manyly use as end cap device with the precast concrete pile point. Now the present invention is compared with it.
The precast concrete pile point is contained in the pile pipe end opening, sink to and stay in underground with sand pocket after underground, can not reuse, take above-mentioned engineering as example, about 1.50 yuan of each precast concrete pile point valency once uses nearly ten thousand of numbers, can not reclaim, by contrast, use the utility model device to make whole engineering price descend about 10%.
