Abstract

The utility model relates to a pulling structural well tool which comprises a well circle and a well cover, wherein the well circle is a cylinder with an outer stress edge at the top of an upper opening; the outer stress edge is fixedly mounted on a wellhead base; and the well cover covers on the well circle. The unresolved problems researched by various countries are solved by the pulling structural well tool; a road is kept smooth and clean for a long time; the service life of the road is greatly prolonged; the unique structure of the pulling stress load well cover is adopted, so that the 'worn edge, worn circle and worn pit' generated by the present bracket bearing force structural base are thoroughly eliminated; and due to the pulling structural well tool, the driving of vehicle and personnel is safe and reliable and a large amount of manpower and social wealth can be saved.

Description

A kind of tractive structural formula well tool

Technical field

The utility model relates to the well tool, particularly relates to a kind of tractive structural formula well tool.

Background technology

Present tractive structural formula well tool all is set to the walling crib body is embedded in the road, makes walling crib be fastened in the inside of bottom surface, when automobile rolls well lid; Well lid sends pressure to walling crib, because the walling crib below is a hollow, pressure all concentrates on the borehole wall that supports walling crib, and the borehole wall is compressed because of the pressure that receives; Walling crib then can produce downward displacement because of the borehole wall compresses, and the road surface on walling crib top in the process that walling crib moves down again, will road pavement produce traction force owing to do not produce displacement; Make road surface breakage, thereby produce the phenomenon in walling crib " mashed limit, mashed circle, mashed hole ", cause rugged hole, road surface gully; The vehicle pitching concussion, noise happens frequently, along with mashed hole constantly enlarges; Shorten the application life of road gradually, by this consumption waste safeguard that renewal expense is countless, beyond doubt to the huge waste of the wealth of society; In addition,, be easy to occur the problem that well lid is lost, the destruction of well lid and losing because now the most of well lids in the tractive structural formula well tool all are and walling crib flexibly connects; Also become mouthful and mouthful to ruin the trap that car is hurted sb.'s feelings, endangering vehicle and pedestrian, and well lid takes place eject the problem of walling crib because of pressure, the well lid displacement is dodged empty; Fragmentation is fallen, and dash to prick and stand upside down, all be the hidden danger in the traffic safety; The well lid end face does not have transverse slope, and none is smooth-going consistent with the road surface, and every well tool makes the driving abundant jump in top, a left side shake right rolling; Be easy to cause the scratch collision accident, by bus, all uncomfortable by bike, what road lost smooth bright and clean, unobstructed attractive in appearance and safety and comfort should have attribute.

The utility model content

The utility model produces the defective of splitting broken mashed limit to above-mentioned tractive structural formula well tool periphery; Find out the basic reason that produces mashed limit; In ground, change traditional walling crib fixing into fixing on the face of land, solved the phenomenon that produces mashed limit because of traction force, thereby protected road and well tool.

In order to achieve the above object; The technical scheme that the utility model provided is: a kind of tractive structural formula well tool, and it comprises walling crib and well lid, said walling crib is the cylindrical shell that a top suitable for reading is provided with the stress outer; Said stress outer is installed on the wellhead receptacle, and said well lid lid is contained on the walling crib.

Further, be provided with the anti-sinking device below the said walling crib.

Further, said walling crib is provided with through hole.

Further, be provided with anti-theft device bottom the said walling crib.

Further, mouth is provided with interior edge at the bottom of the said walling crib inwall, and its inwall bottom is installed with boss, said boss and interior along forming groove.

Further, be provided with lug bottom the said well lid.

Further, said lug is installed in the groove.

Adopt technique scheme, the technique effect of the utility model has:

1. the utility model has been captured various countries and has been made great efforts the unsolved so far difficult problem of research, traditional walling crib is fixed in ground, change fixing on the face of land, has solved the phenomenon that produces mashed limit because of traction force.

2. the utility model is fixed in well lid on the walling crib, has effectively solved the problem of well lid disengaging walling crib.

3. the utility model is equipped with anti-theft device in the walling crib bottom, has prevented that well lid is stolen.
