Abstract
The utility model discloses a kind of improved soil tamper, including base, the body of rod, hammer, scale line, form friction pattern, passage, bolt, fastener.Guard circle is provided with holes on base; perimeter sets some passages; base bottom applies the super-hydrophobic earth material of high intensity; body of rod threaded top buried depth is attached between centre hole of base, the body of rod by bolt, and fastener is connected by bolt with the body of rod; hammer is placed on the body of rod; the shape for hammering bottom into shape is corresponding with the shape of base and guard circle, and the place of holding sets form friction pattern on hammer, and hammer main body outer ring sets scale line.The utility model bar length is variable, and above the place of holding sets form friction pattern；Hammer body peripheral hardware scale line, can accurately measure and hit real density, prevent hammer and body of rod friction from causing the density variation of the unstable generation of compactive effort.Using comfortable；Post screw thread does not connect with susceptor surface, and peripheral hardware guard circle, the body of rod is difficult from fracture of root；Base applies high intensity super hydrophobic coating, not easy-adhesion soil particle.
Description
Technical field
The utility model is related to a kind of civil engineering soil test equipment, particularly a kind of improved soil tamper.
Background technology
Soil tamper is a kind of conventional soil test equipment in engineering construction field, loose earth material need to be impacted into more porcelain
Real soil structure.
Current soil tamper has had many novel improveds, Wu Jianping etc. in terms of real remoulded sample is hit（The patent No.
88205416.3）Ramming device the centrally disposed through hole of axostylus axostyle and base so as to air in soil body discharge；Liu Qingjie etc.（Patent No. CN
102466583 A）Propose when impacting soil, the gas in earth material is discharged by the body of rod of middle control.Chen Wenjie etc.（The patent No.
CN 203069423 U）A kind of New-type soil tamper is proposed, circumferentially direction is set outside depressed part, hammer and base on hammer top
Passage is arranged on ring.
But still there is improper part in use in ramming device：（1）The soil body when hitting real moisture content higher soil sample
Soil tamper bottom easily is attached to, error is caused；（2）The reasons such as friction cause compactive effort deviation, it is impossible to ensure that every layer of soil sample is hit
Actual effect fruit is consistent；（3）In the progress of experiment and epilog, easily occur the situation that rod member root is broken in base, cause
Soil tamper is integrally damaged.
Utility model content
The purpose of this utility model is problem present in solution current techniques, and there is provided a kind of improved soil tamper.It is logical
Cross the device and can realize and avoid soil tamper bottom from adhering to soil sample, prevent body of rod fracture of root, it is ensured that every layer to hit sample highly consistent,
The comfortableness that hammer is used is increased by form friction pattern.
The utility model uses what is be achieved in that：A kind of improved soil tamper, including base, the body of rod, hammer, buckle
Part, hammer is placed on the body of rod and is pressed on base, and guard circle is set at the holes on base, be centrosymmetric on base it is vertical it is uniform between
Every being disposed with some passages, the place of holding is provided with form friction pattern on described hammer；It is provided with described hammer hammer body outer wall
Horizontal scale line, the scale line is recessed to hammer inner side；The body of rod is screwed with base and is connected.
The base end face of above-mentioned soil tamper is circle, and base center top opens up aperture, and aperture inwall is threaded, spiral shell
Certain buried depth is arranged at line top, and aperture outer ring is provided with guard circle, and perimeter sets passage.
The body of rod of above-mentioned soil tamper is bolt connecting type, and connector is mutually nested semicylinder, side cylinder
The body of rod is attached by recessing hole, bolt by recess hole.
The shape at above-mentioned hammer hammer bottom is corresponding with the shape of base and guard circle, and friction is set at hammer upper grip
Scale line is set outside line, hammer hammer body, and hammer bottom scribbles high intensity super hydrophobic coating layer.
Above-mentioned fastener is nested in outside the body of rod, and fixation is screwed by bolt.
Compared with prior art, the utility model beneficial effect is：The utility model is simple in construction, and bar length is variable, uses
Comfortably, and post screw thread of the present utility model does not connect with susceptor surface, peripheral hardware guard circle, it is difficult to fracture from root.Hammer
Scale line is set in vitro, can accurately measure and hit real density, prevents hammer and body of rod friction from causing the close of the unstable generation of compactive effort
Spend deviation.
Brief description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings,
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the diagrammatic cross-section of the utility model base.
In figure：1st, base, 2, the body of rod, 3, hammer, 4, scale line, 5, form friction pattern 6, passage, 7, guard circle.
Embodiment
A kind of improved soil tamper, including base, the body of rod, hammer, fastener, hammer are placed on the body of rod and are pressed on base, institute
Stating the vertical uniform arranged for interval that is centrosymmetric at holes on base on setting guard circle, base has some passages, and described hits
The place of holding is provided with form friction pattern on hammer；Horizontal scale line is provided with described hammer hammer body outer wall, the scale line is into hammer
Side is recessed；The body of rod is screwed with base and is connected.Hammer bottom scribbles high intensity super hydrophobic coating layer.Guard circle is integral type with base
Structure, guard circle is in hollow truncated cone-shaped.The quantity of the passage is four, is separately positioned on the circumference fourth class branch of base
On.The scale line is invested on the outside of hammer hammer body, and scale line range is 10cm.The described body of rod docks for bolt, and bar length can lead to
Connection is crossed to change.The shape at hammer hammer bottom is corresponding with the shape of base and guard circle.Revolved with base by screw thread body of rod bottom
Fasten, body of rod threaded top is less than holes on base horizontal plane.
