Description
Technical Field
The invention belongs to the technical field of municipal engineering drainage, and particularly relates to a novel construction device for an artificial pipe jacking.
Background
At present, the drainage pipeline construction of municipal works generally adopts an artificial pipe-jacking construction process in a construction area which is not provided with excavation and has a lower underground water level. The conventional artificial pipe jacking construction process comprises the following steps: a worker enters the pipeline and uses tools such as a pickaxe and the like to manually dig the soil at the front end of the pipeline, and the soil is conveyed out of the pipeline by using a small-sized cart; after the front end of the pipeline is dug for a certain distance, the pipeline is jacked forwards in the working well by using a jacking equipment jack. The main problems of the traditional artificial pipe jacking method are as follows: 1. the efficiency of digging soil body at the front end of the pipe by manpower is low, and the construction requirement cannot be met due to the slow jacking speed; 2. the manual digging easily causes the phenomenon of over digging larger than the diameter of the pipeline, and disturbs the surrounding soil body, thus causing the increase of the later grouting amount and even the ground settlement; 3. the worker digs at the front end of the pipe and is easy to cause danger.
Disclosure of Invention
The invention aims to overcome the defects of the background technology and provide a novel construction device for an artificial pipe jacking.
The invention is realized by the following technical scheme:
The utility model provides a novel construction equipment of artifical push pipe, includes large-scale jack, still includes a steel sleeve, the front end of steel sleeve is loudspeaker form, and perpendicular loudspeaker form surface evenly fixes a plurality of sword tooth.
Furthermore, four small jacks are symmetrically fixed on the inner wall of the steel sleeve, a baffle is welded at the front end of each small jack and is perpendicular to the inner wall of the steel sleeve, and the small jacks are parallel to the steel sleeve.
Preferably, the small jack is fixed on the inner wall of the steel sleeve through a hoop.
Preferably, the thickness of the steel sleeve is 1-2 cm.
Preferably, the number of the cutter teeth is 4-8.
Preferably, the width of the lower end of the cutter tooth is larger than that of the upper end of the cutter tooth.
Preferably, the thickness of the cutter teeth is 1-2 cm.
Preferably, the cutter teeth are welded to the steel sleeve.
The invention has the beneficial effects that:
1. Compared with manual digging speed, the jacking force of a large jack and the soil cutting speed of the cutter teeth of the steel sleeve are doubled;
2. During the jacking process, the surrounding soil body can be compacted, the soil layer is stabilized, and the ground settlement is not easy to cause;
3. Workers do not need to dig soil in front, and the risk of overexcavation at the front end of the pipe does not exist;
4. The influence of irregular manual excavation surfaces on the jacking of the pipeline does not exist in the jacking process, the direction and the elevation are easy to control, overlarge deviation cannot occur, and the small jack can be adjusted in the process according to actual conditions;
5. The construction device is quick and convenient to construct, the construction period is obviously shortened, the cost is saved, the quality and the safety are ensured, and the construction device is suitable for wide popularization.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural view of the small jack and the baffle plate of the invention.
In the figure, 1 steel sleeve, 2 cutter teeth, 3 small jacks, 4 baffles and 5 hoops.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention comprises a large jack for providing propelling force, and the large jack is widely applied to pipe jacking construction and is not described again. The invention also comprises a steel sleeve 1, the thickness of the steel sleeve 1 is preferably 1-2cm, and the front end of the steel sleeve 1 is trumpet-shaped as shown in figure 1. A plurality of cutter teeth 2 are uniformly welded on the horn-shaped surface of the vertical steel sleeve 1, the number of the cutter teeth 2 is preferably 4-8, and 5 cutter teeth 2 are uniformly welded in the attached drawing 1 of the embodiment to form an annular cutter tooth group. The thickness of the cutter teeth 2 is between 1 cm and 2cm because the cutter teeth 2 are used for cutting the front soil body, and the cutter teeth 2 are made of stainless steel. Preferably, the width of the lower end of the cutter tooth 2 is larger than that of the upper end of the cutter tooth, that is, the whole cutter tooth 2 is in a shape with a wide lower part and a narrow upper part.
Preferably, four small jacks 3 are symmetrically fixed on the inner wall of the steel sleeve 1 through a hoop 5, the four small jacks 3 are respectively fixed on the upper wall, the lower wall, the left wall and the right wall of the steel sleeve 1, and the small jacks 3 are parallel to the steel sleeve 1, namely the force application direction of the small jacks 3 is parallel to the steel sleeve 1 and is the same as that of the large jacks. The front ends of the small jacks 3 are respectively provided with a baffle 4, the baffles 4 are perpendicular to the inner wall of the steel sleeve 1 and are welded on the inner wall of the steel sleeve 1, and the force of the small jacks 3 acts on the baffles 4.
The working process is as follows: during construction, the steel sleeve 1 is placed in front of a pipeline, the steel sleeve 1 and the pipeline are simultaneously pushed forwards by means of a large jack in a working well, the front soil body is cut into by extrusion of the annular cutter teeth 2 at the front end of the steel sleeve 1 at the moment, the soil body is cut into blocks and falls into the steel sleeve 1, a worker directly carries a truck to transport the pipeline out, the worker is not required to dig at the front end of the pipeline, and the jacking efficiency is greatly improved. If there is great deviation in the jacking direction, at this moment, adjust the direction through the small-size jack 3 of steel sleeve 1 inner wall, launch one or more small-size jack 3 on the inner wall according to the deviation direction, the power of small-size jack 3 acts on baffle 4, and steel sleeve 1 is uneven in the atress in the jacking direction like this, will produce a moment of flexure to the direction of adjustment steel sleeve 1.
The novel construction device for the artificial pipe jacking is adopted for construction, the traditional artificial sleeving and digging is replaced, the traditional artificial jacking can be jacked for 4-5 meters every day, and the device can be jacked for 8-10 meters every day, so that the efficiency is greatly improved, the construction is simple and convenient, the quality and the safety are guaranteed, the construction period can be obviously shortened, and the labor force is saved.
