Abstract
The utility model discloses a simple and practical shaft excavation survey dereeler, which comprises a metal plumb, a cross-shaped rack body and a circular ring-shaped concrete table, wherein the metal plumb is connected to the center of the cross-shaped rack body through a plumb line; the metal plumb is horizontally provided with a measuring rod with a level bar; the metal plumb and the concrete table are coaxially arranged; the top of the concrete table is provided with four vertical locating rods evenly distributed along the circumferential direction of the concrete table; the lower end of the locating rod is fixedly connected with the concrete table; and the cross-shaped rack body is provided with locating holes which correspond to the four locating rods. In the utility model, the cross-shaped rack body and the metal plumb are utilized to accurately locate the center of a shaft, and a survey crew surveys and locates the excavation side line of the shaft at different altitudes of the shaft through the measuring rod with the level bar and the center of the metal plumb. The utility model has simpleness in operation, low input cost and high survey paying off speed, and the precision completely meets the standard requirement.
Description
Technical field
The utility model relates to a kind of shaft excavation and measures actinobacillus device.
Background technology
At present, the hydroelectric project construction often runs into the vertical shaft project under construction, the general excavation earlier of vertical shaft one pilot shaft, once expand the type that scrapes out again from the top down, vertical shaft expands and to dig in the supporting process and will construct in strict accordance with design size, and to dig supporting very fast cycling time owing to expand, if want survey crew to utilize instrument to locate excavatoin line at every turn, need the time longer, also can affect construction speed.
The utility model content
At above-mentioned prior art, emit the shaft excavation line as early as possible in order to solve in the shaft excavation work progress survey crew, thereby the problem of accelerating construction progress, the utility model provides a kind of shaft excavation of simple and easy practicality to measure actinobacillus device, cost is low, simple to operate, payingoff speed is fast, and precision satisfies code requirement fully.
The technical solution of the utility model is: actinobacillus device is measured in a kind of shaft excavation of simple and easy practicality, comprise the metal sash weight, cruciform support body and circular coagulation earthen platform, described metal sash weight is connected in the center of cruciform support body by the sash weight line, described metal sash weight is provided with the sounding rod of horizontally disposed band surveyor's staff, described metal sash weight and the coaxial setting in coagulation earthen platform, top, described coagulation earthen platform is provided with along its circumferential equally distributed four vertical backstays, fixedly connected with the coagulation earthen platform in the lower end of described backstay, described cruciform support body is provided with and four pilot holes that backstay is corresponding.
As preferably, described cruciform support body is intersected by two channel-section steels and is welded.
The beneficial effects of the utility model are: utilize cruciform support body and metal sash weight accurately to locate the center of vertical shaft, survey crew at the different elevation of vertical shaft by the sounding rod of band surveyor's staff and the excavation sideline that metal sash weight center measurement and positioning goes out vertical shaft, the digging measure actinobacillus device is simple to operate, be suitable for diameter 10m with interior shaft excavation construction survey unwrapping wire, input cost is low, and it is fast to measure payingoff speed, and precision satisfies code requirement fully.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a vertical view of the present utility model.
Among the figure: 1. channel-section steel, 2. coagulation earthen platform, 3. metal sash weight, the 4. sounding rod of band surveyor's staff, 5. backstay, 6. sash weight line, 7. vertical shaft waits to excavate body 71.
Embodiment
As a kind of embodiment of the present utility model, as depicted in figs. 1 and 2, actinobacillus device is measured in a kind of shaft excavation of simple and easy practicality, comprise a bigger metal sash weight 3, cruciform support body and circular coagulation earthen platform 2, described cruciform support body is welded by two channel-section steels, 1 intersection, described metal sash weight 3 is connected in the center of cruciform support body by sash weight line 6, described metal sash weight 3 is provided with the sounding rod 4 of horizontally disposed band surveyor's staff, described metal sash weight 3 and the 2 coaxial settings of coagulation earthen platform, 2 tops, described coagulation earthen platform are provided with along its circumferential equally distributed four vertical backstays 5, fixedly connected with coagulation earthen platform 2 in the lower end of described backstay 5, described cruciform support body is provided with the pilot hole corresponding with four backstays 5.
In actual applications, at first at vertical shaft 7 well head casting concrete platforms 2, pre-buried good backstay 5 when construct in coagulation earthen platform 2, reserve pilot hole at cruciform support body and backstay 5 corresponding positions, metal sash weight 3 is fixed on the center of cruciform support body by sash weight line 6, manually the cruciform support body is placed on the coagulation earthen platform 2 during unwrapping wire, backstay 5 inserts in the corresponding pilot hole, metal sash weight 3 is put into height that need to measure unwrapping wire by sash weight line 6, utilizes the sounding rod 4 of the central point of metal sash weight 3 and band surveyor's staff to orient the excavatoin line of waiting to excavate body 71 of vertical shaft 7.
