Abstract
The utility model discloses a small size underground cross hole drilling machine, the front end of which is provided with a hollow drilling bit of a blowhole, a plurality of hollow drilling stems, a propulsion handle, a water pipe, and a water pump, which are connected in turn, wherein the hollow drilling stems are arranged on a guiding support and the water pipe is connected with the propulsion handle through a sleeve joint. The utility model which is suitable for constructing drilling holes for invisible laid underground pipelines with a 30-meter cross distance has the advantages of simple structure, low cost, convenient operation and maintenance, small occupation area in construction, and high speed in construction.
Description
Technical field
The utility model relates to a kind of construction equipment of provided underground pipeline, specifically is a kind of top soil is laid underground utilities at underground cross drilling auger that do not excavate.
Background technology
At present, the open drain laying method of excavated pavement is adopted in the laying of underground utilities more, influences traffic in the work progress, also causes the road surface sinking in addition or slight crack is arranged.Relatively large underground horizontal drilling machine is also arranged, but adopt fewer, its main cause is the cost height, uses the place big, transportation difficulty etc.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of small-sized underground horizontal drilling machine is provided.
The purpose of this utility model is achieved in that a kind of small-sized underground horizontal drilling machine, front end has the hollow boring bit of hole for water spraying, some hollow drills, propelling handle, water pipes to be connected successively with water pump, hollow drill is placed on the guiding trestle, and water pipe is connected by muff joint with advancing between the handle.
Described hollow boring bit, some hollow drills, advance between the handle and can adopt screwed connection.
Described screwed connection can be that the silk head of parts is screwed in the silk braid of another parts.Also can be that each parts connecting portion all is a head, adopt the sleeve pipe that has silk braid to connect between the silk head.
Described water pump preferably adopts high-pressure pump.
Advantage of the present utility model is: simple in structure, with low cost, help wide popularization and application.Operating maintenance is convenient, and the construction area area is little, and speed of application is fast, is suitable for crossing the dark floor file underground pipelines construction drill of about 30 meters of distances.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model drill bit sectional view.
Fig. 3 is a kind of connected mode structural representations of parts of the present utility model.
Fig. 4 is the another kind of connected mode structural representations of parts of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with schematic diagram:
Embodiment 1: as shown in Figure 1 and Figure 2, a kind of small-sized underground horizontal drilling machine, front end has the hollow boring bit 1 of hole for water spraying 9, some hollow drills 2, propelling handle 5, water pipes 7 to adopt successively with high-pressure hydraulic pump 8 and be connected, connect as shown in Figure 3 between drill bit 1, drilling rod 2, the propelling handle 5, adopt the silk 11 of parts to be screwed in the silk braid of another parts 10, water pipe 7 is connected by muff joint 6 with advancing between the handle 5, and hollow drill 2 is placed on the guiding trestle 3.
Embodiment 2: further feature is with embodiment 1, and as shown in Figure 4, difference is that each parts junction all is a silk 12, adopts the sleeve pipe 13 that has silk braid to connect between the silk 12.
When drilling construction, at first to dig out the construction hole, on the wall of hole, select punch position and adjust fixed support 3, connect drill bit 1, drilling rod 2 then, advance handle 5, water pipe 7 and high-pressure hydraulic pump 8,8 work switch on the pump when manually rotation advances handle 5 to make the drill bit rotation, in boring moving process, water under high pressure washes away chisel edge earth by water pipe 7, drilling rod 2, drill bit 1, forming mud flows out from boring, after drilling rod 2 commentaries on classics are entered, drilling rod 2 of adjunction makes boring constantly advance like this, finally finishes drill tasks.
