Background technique
Currently, jacking construction is broadly divided into mechanical jacking and artificial two class of push pipe, mechanical jacking be suitable for geology it is single and
The location that no underground line influences.But under current city status, mechanical jacking is difficult to exhibit one's skill to the full, once going wrong, has
Place can heavy excavation take head, place can only not abandoned using and mechanical jacking equipment price is high.Therefore, people
Work push pipe is form of construction work most reliable, most practical in current construction.Artificial push pipe is also known as cutting edge propelling method, current artificial top
Tube apparatus is only arranged a cutting edge in front end and is used for cutting soil.
The prior art is primarily present following defect:
Artificial conduit jacking cannot achieve " first push up and dig afterwards ", because common push pipe tube wall thickness is 10cm-20cm, if first
Soil layer need to be headed into for pipeline by digging behind top, this top power greatly especially long-distance pipe jacking, it is easy to by middle part or end tubing top
It can only first be dug when splitting, therefore constructing and push up but not can guarantee construction personnel's safety afterwards, in addition, for rich water geology such as mobile sand
Matter, the prior art can not construct, or one side safety is poor when inadequate construction, does not on the other hand consider surface subsidence, cuts the earth
Amount greatly, be seriously obstructed by progress, is unable to control surface subsidence therefore cannot pass through existing pipeline, road or have to close on and constructs
Object location, bad adaptability.
The information disclosed in the background technology section is intended only to deepen the reason to the general background technology of the utility model
Solution, and it is known to those skilled in the art existing to be not construed as recognizing or imply that the information is constituted in any form
Technology.

Specific embodiment of the present utility model is described in detail below in conjunction with attached drawing.It should be understood that herein
Described specific embodiment is only used for describing and explaining the present invention, and is not intended to limit the utility model.
It please refers to shown in Fig. 1-Fig. 3, below in conjunction with attached drawing to head safeguard structure provided in this embodiment and artificial top
Pipe device elaborates.
On the one hand, as shown in figures 1 and 3, head safeguard structure provided in this embodiment is mounted on the front end of push pipe 2, packet
It includes: protection main body 1；The Vacancy for accommodating construction personnel is formed inside protection main body 1, protect 1 both ends open of main body and is appointed
One end is connected with the front end of push pipe 2；It is provided in protection main body 1 multiple for draining the permeable hole 4 and protection main body 1 of protecting sand
Thickness be less than push pipe 2 thickness.Specifically, it protects the middle and lower part of main body 1 to be equipped with multiple permeable holes 4, allows water along multiple
Direction dispersion flows, reduce pressure, and sand risk is gushed in reduction.
In the present embodiment, any one open end of head safeguard structure is mounted on to the front end of push pipe 2, protection main body 1
Thickness is less than the thickness of push pipe 2, so only needing smaller jacking power that can be inserted into the soil body, construction personnel digs in Vacancy
Soil is dug afterwards to realize first to push up, it is ensured that construction worker's safety.It is played in protection 1 jacking of the main body soil body to be excavated super
The effect of preceding supporting increases single Excavation Length so that development end is not influenced by rich water geology and unstable phenomenon occurs,
Improve operating efficiency.Protection main body 1 plays a protective role to the 2 top soil body of push pipe, considerably reduce backbreak, tube top it is de-
It is empty, collapse etc. caused by surface subsidence.Sand is protected in the permeable hole 4 being arranged in protection main body 1, effective draining, and shunting reduces driving
Sand risk is gushed in face water pressure, reduction.The present embodiment effectively raises adaptability, safety and the construction effect of artificial push pipe 2
Rate, effective control of surface subsidence so that push pipe 2 pass through existing pipeline, road and close on structures etc. it is higher to settlement request
Location when have higher reliability and adaptability.Meanwhile the present embodiment is to other easily landslide depressions such as landfill house refuse
Complicated geological paragraph have very strong adaptability.
It further include bottom baffle 3 as shown in Fig. 2-Fig. 3 in the optinal plan of the present embodiment；Bottom baffle 3 is installed on anti-
It protects inside main body 1, protects between main body 1 and bottom baffle 3 and be connected with supporting element 31.Supporting element 31 is slidably mounted on protection
Inside main body 1.It is connected with anchor bolt on supporting element 31, protects inside main body 1 and forms pin hole, anchor bolt is located in pin hole and can be opposite
It is slided in pin hole.Specifically, supporting element 31 is iron brace.
Specifically, protection main body 1 is cirque structure, and bottom baffle 3 is semicircular structure, and the diameter of bottom baffle 3
It is identical as the protection internal diameter of main body 1.Multiple permeable holes 4 are provided on bottom baffle 3.
It should be pointed out that first will protection 1 jacking of main body pick in 2 front of push pipe installation protection main body 1, jacking when construction
Into in face, construction personnel can carry out excavation construction, and realization, which first pushes up to dig afterwards, guarantees personnel safety.Rich water geology is excavated to reserved slope
Jacking again behind face 5 (reserved slope surface 5 can guarantee that development end is stablized).According to geological condition, as drift sand is serious or reserved slope surface 5
When slope foot is longer, bottom baffle 3 is installed, the setting of bottom baffle 3 is so that the slope foot length of reserved slope surface 5 effectively reduces, simultaneously
The stability of development end is increased, the generation for gushing the risks such as sand is reduced.The fit system of anchor bolt and pin hole is adjusted convenient for being moved forward and backward
Whole 5 length of reserved slope surface can take down at any time again in the case where development end is more stable, so that it is mobile flexibly simple, it is removable to be convenient for
Construction has very strong practical operation, while being also provided with permeable hole 4, plays the role of draining to development end and protects sand.
In the optinal plan of the present embodiment, the wall thickness of protection main body 1 is 2cm, length 150cm.Push pipe 2 is with a thickness of 10-
The thickness of 20cm, protection main body 1 are only the 1/10-1/5 of 2 thickness of push pipe, convenient in the head insertion soil body.
The present embodiment also provides a kind of 2 device of artificial push pipe, including actuator, push pipe 2 and head safeguard structure；Push pipe 2
Front end be connected with cutting edge 21, protection main body 1 is installed on cutting edge 21, and actuator can push push pipe 2 and protection main body 1 to push up
Into.The present embodiment includes head safeguard structure, therefore all for having the advantages that above-mentioned head safeguard structure has, no longer superfluous herein
It states.
Specifically, actuator uses jack.The length of cutting edge 21 is 30cm.
The head safeguard structure of the present embodiment and 2 device of artificial push pipe are illustrated above, still, the present embodiment is not
It is defined in above-mentioned specific embodiment, without departing from the scope of the claims, various deformations or change can be carried out
More.The various modifications and change that the present embodiment is included within the scope of the claims.
