Abstract

The utility model relates to a vibrating geotome, adopting vibrating box body type earth borrowing technology. The vibrating geotome not only has the advantages of large earth-borrowing amount at one time, good construction quality, etc., but also can dig pile holes of various hole diameters and shapes according to various engineering requirements. The vibrating geotome which is composed of a vibrating hammer head, an earth storing box and a digging head can directly borrow earth and dig holes, suitable to be an ideal construction machine.

Description

Vibrating geotome

The utility model relates to a kind of soil sampler.

In construction foundation working, often adopt the method consolidated subsoil of in situ pile, and the in-site pouring pile driving construction should be dug pore-forming.At present advanced cutting hole creating technology is to adopt the fully-sleeved filled pile machine, that is: steel sleeve is pressed into undergroundly, uses in steel sleeve towards the gripper soil taking hole forming.

Prior art dash gripper, be to grab tooth with at least two to connect with the same Connection Block of circular shaft respectively, fixing steel wire capstan winch on Connection Block, the two ends of steel wire are separately fixed at grabs on the tooth, utilizes steel wire windlass steel wire, makes to grab the tooth head and close up or separate.Towards the gripper operating principle: at first will grab the tooth head and separate, and aim at the excavation hole, and rely on the deadweight of falling, and impact underground making and grab the tooth head and insert in the soil, and close up and grab the tooth head and soil is placed grab between the tooth, and after portalling towards gripper with wire rope traction, separate and grab the tooth head and fall native towards grappling fixture.Should exist problems such as the amount of fetching earth is little, inefficiency towards gripper; The easy damaged that in steel sleeve, fetches earth steel sleeve, but and direct perforate is difficult to reach quality requirement.

The purpose of this utility model just provides a kind of convenient and practical, borrow equipment of big, the high efficiency of the amount of fetching earth once, promptly can be with the supporting use of steel sleeve, and the soil sampler of the perforate of can directly fetching earth again.

Vibrating geotome of the present utility model is by the vibration tup of prior art with deposit native case, excavating head and latch and form; The vibration tup is fixed on deposits native box top; Deposit an end of native case and an end of excavating head and be connected, deposit the other end of native case and the other end of excavating head corresponding pin hole is set, on the excavating head inwall, connect at least two plate washers and fix a plate washer frame with hinge respectively with hinge; The excavating head bottom should be designed to sharp type.The also available hinge of plate washer is connected on the plate washer frame, and on the inwall of excavating head fixing plate washer platform.Deposit native case and excavating head and can correspondingly make round, square, triangular form and multiangular.

The operating principle of Vibrating geotome of the present utility model: at first the native case of depositing of Vibrating geotome and excavating head are closed up and use latch locking, with Vibrating geotome with wire rope traction put into the excavation hole at the bottom of, the Vibration on Start-up tup drives excavating head to deposit native case and gos deep into soil layer, and earth backs down plate washer and enters and deposit in the native case; When earth be full of deposit native case after, stop to vibrate tup work, rise with the wire rope traction Vibrating geotome, utilize the weight of depositing earth in the native case to close plate washer, earth is stored in the native case; After soil sampler portals, take out latch and open excavating head, the earth of depositing in the native case is outwelled.

Vibrating geotome of the present utility model, adopted the vibrating type casing technology that fetches earth, not only overcome towards gripper disposablely fetch earth less, problem such as inefficiency, construction cost height, and have characteristics such as hole quality height, hole shape scope be wide, no matter be in steel sleeve, to fetch earth, still be used for direct perforate, all can normal construction.

Embodiment 1: Vibrating geotome as shown in Figure 1, by vibration tup (1) and deposit native case (2), excavating head (3) and latch (4) and form, and draw with steel cable (11).The vibration tup is fixed on deposits native box top; Depositing an end of native case and an end of excavating head is connected with hinge (5), deposit the other end of native case and the other end of excavating head corresponding pin hole (6) is set, use hinge (7) connection at least two plate washers (8) respectively and fix a plate washer frame (9) on the excavating head inwall, the effect of plate washer frame is not make the plate washer tenesmus.

Embodiment 2: Vibrating geotome as shown in Figure 1, 2, baffle plate also can be connected on the plate washer frame with hinge, and on the inwall of excavating head fixing plate washer platform (10), the effect of plate washer platform is not make the plate washer tenesmus.

Embodiment 3: the Vibrating geotome shown in Fig. 1,3-A or 1,2,3-B, it is round will depositing native case and excavating head respective design, can excavate circular opening.

Embodiment 4: the Vibrating geotome shown in Fig. 1,4-A or 1,2,4-B, it is round will depositing native case and excavating head respective design, can excavate square hole.

Embodiment 5, the Vibrating geotome shown in Fig. 1,5-A or 1,2,5-B, it is round will depositing native case and excavating head respective design, can excavate the triangle hole.

Embodiment 6: the Vibrating geotome shown in Fig. 1,6-A or 1,2,6-B, it is round will depositing native case and excavating head respective design, can excavate the polygonal hole.

Claims

1, the Vibrating geotome of a kind of employing vibration tup (1) by the vibration tup with deposit native case (2), excavating head (3) and latch (4) and form, is characterized in that vibrating tup and is fixed on and deposits native box top; Deposit an end of native case and an end of excavating head and be connected, deposit the other end of native case and the other end of excavating head corresponding pin hole (6) is set with hinge (5); Use hinge (7) connection at least two plate washers (8) on the excavating head inwall respectively and fix a plate washer frame (9); The excavating head bottom should be designed to sharp type.
