Abstract
The invention discloses a manual pipe bit which is mainly composed of a shovel head, a balance weight lever and a lengthening bar. The front end of the balance weight lever is connected with the shovel head, the rear end of the balance weight lever is connected with the lengthening bar, the shovel head is a barrel with a rear port sealed, the balance weight lever is fixed on the rear end face of the shovel head, and a side wall of the shovel head is provided with a sample taking port for taking out soil mass samples. The shovel head is the barrel and is simple in structure. Compared with a shovel head of an existing Luoyang shovel, due to the fact that area of the shovel head contacted with soil is increased and friction force between the soil and an inner wall of the shovel head is increased, underground soil mass can be taken up as much as possible, and the problem that the soil cannot be taken out easily once the Luoyang shovel is met with underground water is solved. The manual pipe bit is light and convenient to carry and use. After tunneled into the shovel head, the soil mass can be taken out through the sample taking port, and the manual pipe bit is simple to operate, large in tunneling depth and favorable for smooth development of engineering geologic investigation.
Description
Technical field
The present invention relates to the simple and easy exploring equipment of a kind of engineering geologic investigation shallow-layer cohesive soil, sand, particularly a kind of artificial pipe bit.
Background technology
In recent years, along with the fast development of mountain area engineering construction (as mountainous area highway), the prospecting task also increases gradually.Usually, intermountain depression, simple stratum can adopt simple and easy exploring equipment to find out engineering geological conditions.
At present, the most frequently used simple and easy exploring equipment is luoyang spade, luoyang spade is made up of shovel head, weight linear meter and extension bar, the shovel head is half cylindrical shell shape, be mainly used to dig underground soil layer and it is carried upper ground surface, the effect of weight linear meter is just as the front of javelin, shovel is added accurately first watch, effectively dig into to the soil layer deep, the front end of weight linear meter is connected with the shovel head with welding manner, extension bar is connected in the screw thread mode with the rear end of weight linear meter, and extension bar constantly spreading lengthens entire length to adapt to the soil layer of different depth.In use, luoyang spade stabs vertically downward and hits ground, utilizes the shovel head underground soil zone can be gone out, and digs out a deep hole that diameter is about tens centimetres gradually, analyzes the character of the underground soil layer of shallow-layer according to the structure of taking soil out of, color, density and various inclusion.Luoyang spade possesses plurality of advantages such as light, simple to operate in the engineering investigation process.
Yet, luoyang spade also has the following disadvantages in the engineering investigation use: when tunneling in cohesive soil, if run into underground water, owing to the frictional force that has reduced between soil and the shovel inwall, the phenomenon that can be difficult to fetch earth, in addition, if run into loose layer of sand, also it can't be taken to ground, therefore, limit the degree of depth of exploration, be unfavorable for carrying out smoothly of engineering geologic investigation.
Summary of the invention
The object of the present invention is to provide the artificial pipe bit of carrying out smoothly that a kind of simple in structure, light, simple to operate, tunnelling footage is big, be conducive to engineering geologic investigation.
Above-mentioned purpose of the present invention realizes by following technical measures: a kind of artificial pipe bit, mainly formed by shovel head, weight linear meter and extension bar, the front end of described weight linear meter is connected with the shovel head, its rear end is connected with extension bar, it is characterized in that: described shovel head is the cylindrical shell of rear port sealing, described weight linear meter is fixed on the rear end face of described shovel head, has for the sample tap that takes out soil body sample at the described sidewall that shovels head.
Shovel head of the present invention is cylindrical shell, simple in structure, compare with the shovel head of existing luoyang spade, owing to increased the area that contacts with soil, and then soil and the frictional force of shoveling between the inwall have been increased, therefore the underground soil body can be brought up as much as possible, avoided luoyang spade one to meet underground water, just be difficult to the situation that soil is taken out; The present invention carries and uses lightly, after the soil body is tunneled shovel head, can the soil body be taken out by sample tap, and simple to operate, tunnelling footage is big, is conducive to carrying out smoothly of engineering geologic investigation.
As one embodiment of the present invention, at a described drill bit that has additional tubular that shovels, described drill bit links to each other with the front port of described shovel head by the structure that removably connects.
As another embodiment of the invention, have additional the drill bit of tubular at described shovel head, described drill bit links to each other with the front port of described shovel head by the structure that removably connects, be provided with cover plate for this front port of shutoff at the front port of described drill bit, described cover plate is hinged on the inwall of described drill bit, mouth along described front port is provided with the flanging that bends inwards along circumference, described passings is realized shutoff at described flanging so that in sand when driving cover plate open make sand enter in the shovel head or when mentioning in the shovel head sand push the cover plate pass and close.Can be applicable to the driving of loose sand well and fetch earth, loose sand can be taken to ground smoothly.
As optimal way of the present invention, the described structure that removably connects adopts screw connection structure.
The present invention also has following embodiment:
Described shovel head and described weight linear meter are for being welded to connect.
Described weight linear meter and described extension bar are for being threaded.
Described extension bar is several, and the rod end of several extension bars is connected extension bar by the joint screw thread connection respectively.
Compared with prior art, the present invention has following significant effect:
⑴ shovel head of the present invention is cylindrical shell, simple in structure, compare with the shovel head of existing luoyang spade, owing to increased the area that contacts with soil, and then soil and the frictional force of shoveling between the inwall have been increased, therefore the underground soil body can be brought up as much as possible, avoided luoyang spade one to meet underground water, just be difficult to the situation that soil is taken out.
⑵ on the shovel head drill bit is installed, can changes according to the soil property situation and use two kinds of different drill bits, both can when cohesive soil is met water, the soil body can be taken out smoothly, be applicable to the driving of loose sand again and fetch earth.
⑶ can take out the soil body by sample tap after the soil body is tunneled the shovel head, and simple to operate, tunnelling footage is big, is conducive to carrying out smoothly of engineering geologic investigation.
Of the present invention simple in structure, carry and use light, practical, but wide popularization and application is in the engineering investigation field.
