Abstract

The utility model discloses a grotto inner pressure steel pipe unloading support device, wherein a jack on a grotto inner transport vehicle is arranged below pressure steel pipes through support legs, and steel supports are welded on the two sides of the pressure steel pipes. The grotto inner pressure steel pipe unloading support device can solve the mounting problem of the pressure steel pipes in the conditions that large hoisting equipment can not arranged in narrow grottos, achieves rapid in place of the pressure steel pipes, and is safe, convenient and practical.

Description

A kind of cavern internal pressure steel pipe bracing or strutting arrangement of unloading
Technical field
The utility model relates to a kind of large hydropower station penstock mounting method, especially a kind of in narrow hole, not possessing under the condition of arranging large lifting equipment, and the device of pressure steel pipe of hydropower station is installed.
Background technology
In the narrow hole of large hydropower station penstock in the installation in position process, often face narrow space in hole, be difficult to arrange the difficult problem of large lifting equipment, as pressed traditional construction technical method, must precoat below steel pipe concrete buttress or make the steel buttress, in order to set up jack on buttress, penstock is pushed up from transport trolley, this job practices cost is higher, and, when narrow, precipitous in-cavity construction, working security will be on the hazard, therefore, must a kind of safe, efficient erecting device of design.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of cavern internal pressure steel pipe bracing or strutting arrangement of unloading, can solve in narrow hole, at the installation question that does not possess the condition downforce steel pipe of arranging large lifting equipment, realize that penstock is in place fast, safe, convenient, practical.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of cavern internal pressure steel pipe bracing or strutting arrangement of unloading, and the jack in hole on transport trolley is arranged on the penstock below by supporting leg, and the penstock both sides are welded with type steel support.
Type steel support is the support of " eight " word.
Type steel support is fixedly mounted on the both sides stiffening ring of penstock near the track outside.
Supporting leg is steel corbel.
A kind of cavern internal pressure steel pipe that the utility model provides bracing or strutting arrangement of unloading, by jack by penstock top destage car certain distance, then utilize uneven on the wall of hole, set up type steel support between hole wall and steel pipe, then chassis is exited, set up jack again between steel pipe and attachment rail, by regulating jack, the support of mowing shaped steel " eight " word, by penstock, progressively adjust in place, can solve in narrow hole, at the installation question that does not possess the condition downforce steel pipe of arranging large lifting equipment, realize that penstock is in place fast, safety, convenient, practical.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, a kind of cavern internal pressure steel pipe bracing or strutting arrangement of unloading, the jack 4 on the interior transport trolley 2 in hole 6 is arranged on penstock 7 belows by supporting leg 3, and penstock 7 both sides are welded with type steel support 5.
Type steel support 5 is the support of " eight " word.
Type steel support 5 is fixedly mounted on the both sides stiffening ring of penstock 7 near track 1 outside.
Supporting leg 3 is steel corbel.
It is of the present utility model that to install and use process as follows:
1, when penstock 7 slippages after assigned address, set up jack on the case beam of transport trolley 2, penstock 7 jackings are left to transport trolley 2 certain distances.
2, welding type steel support 5 on the both sides stiffening ring in penstock 7 close track 1 outsides, type steel support becomes " eight " word to be supported on crag recess in hole, and the form of " eight " word support and support origin of force can change flexibly according to situation and the steel pipe angle of inclination of position of living in crag.
3, the jack 4 under supporting leg 3 is unclamped, pull out transport trolley 2.
4, set up jack 4 between track 1 and supporting leg 3, by regulating jack 4, the support of mowing " eight " word, weighing, the penstock 7 of tens of tons is adjusted to the designated mounting position.
The utility model has obtained successful Application in the penstock installation process of Three Gorges Projects underground power station, the Three Gorges oblique straight section of ground voltage power penstock installation is 60 ° of steep slopes, only approximately 1 meter of distance between hole wall and steel pipe, narrow space, the penstock diameter is 13.5 meters, approximately 60 tons of the weight of each penstock delivery unit, as adopt traditional concreting buttress or make steel buttress method and carry out steel pipe and unload, in place, construction safety, progress all is difficult to guarantee, adopt this bracing or strutting arrangement, construction safety and progress have not only been guaranteed, and reduced construction cost, obtained good effect.
