Abstract
The utility model discloses a cable tunnel ground anchor. The cable tunnel ground anchor comprises an anchoring steel plate which is pre-buried in a concrete slab. The upper end of the anchoring steel plate is fixedly connected with a connecting rod. The top portion of the connecting rod will not exceed the surface of the concrete slab. The connecting rod is provided with a screw hole in the axial direction. The screw hole is sealed by a sealing element. The sealing element and the connecting rod are in detachable connection. The cable tunnel ground anchor of the utility model has following advantages that the ground anchor does not need to be cut, after the cable laying process is completed, the ground anchor does not need to be cut, what an operator needs to do is to screw the upper portion of the ground anchor off with a wrench and perform sealing with a sealing bolt; operational dangerous can be avoided, the ground anchor can be screwed off with the wrench in a manual manner, no live operation or hazardous gas operation is needed, no waste gas, waste residue or sparks will be generated; the ground anchor can be used repeatedly, in the later cable maintenance or other circuit laying process, the original ground anchor still can be used, and unnecessary repeated construction can be avoided.
Description
Technical field
The utility model relates to a kind of novel cable tunnel earth anchor being applied in city cable Tunnel Engineering.
Background technology
At present, along with urban construction and development, increasing electrical network project adopts city cable tunnel, than set up tower and conductor more than ground, city cable tunnel have floor space little, lay flexibly, beautify the advantages such as the appearance of the city.
In city cable Tunnel Engineering cable construction process, for cable, install and towing point is provided and for the stress point of trailing cable is provided in cable laying process, is conventionally referred to as city cable tunnel earth anchor.
Conventional city cable tunnel earth anchor is to adopt round steel on cable tunnel base plate, to make suspension ring, it is highly 200mm left and right, for cable laying provides trailing cable stress point, its structural representation as shown in Figure 1, it is pre-buried earth anchor reinforcing bar 5 in concrete slab 1, the top of earth anchor reinforcing bar 5 exceeds the surface of concrete slab 1, and earth anchor reinforcing bar 5 need to cut after installation.
Conventional earth anchor is made simple, easy construction, but also there is certain problem:
1, conventional earth anchor needs to cut after cable laying completes, otherwise the current safety of impact;
2, during the cutting of conventional earth anchor after cable laying completes, adopt machinery or flame cutting.Machine cuts need to be introduced construction power supply again, in construction, can cause spark, discharges flue dust and gas, affects cabling safety, and workmen is brought to potential safety hazard.Flame cutting need to be carried corresponding gas cylinder, has thermal-flame in construction, discharges flue dust and gas, can affect equally cabling safety, and workmen is brought to potential safety hazard;
3, after conventional earth anchor cutting, when later stage cable is changed maintenance or is laid the cable in other loops, just need to be on base plate again perforate make earth anchor, the operating maintenance in later stage is made troubles, in cable tunnel, construction bring potential safety hazard can to existing cable and workmen again.
Therefore, need improve prior art.
Utility model content
The purpose of this utility model is exactly according to the deficiency of above-mentioned background technology, to provide a kind of simple in structure and reusable novel cable tunnel earth anchor.
Existing cable tunnel earth anchor is explained in detail in background technology as shown in Figure 1, in this, repeats no more.
The technical solution of the utility model is: a kind of cable tunnel earth anchor, it comprises the anchor plate being embedded in concrete slab, the upper end of described anchor plate is fixedly connected with connecting rod, described connecting rod top does not exceed the surface of concrete slab, connecting rod offers screw vertically, described screw is by seal shutoff, and described seal and connecting rod removably connect.
Be preferably: described connecting rod is taper pin with internal thread, described seal for taper pin with internal thread in the first shutoff bolt of matching of screw, the height after described shutoff bolt is installed is no more than the surface of concrete slab.
Be preferably: described connecting rod is taper pin with internal thread, described seal for taper pin with internal thread in the second shutoff bolt of matching of screw, described the second shutoff bolt comprises shutoff screw rod, described shutoff screw rod upper end is provided with sealing ring.
The utility model is in use: taper pin with internal thread is directly welded to connect on anchor plate by bottom, pre-buried in concrete slab before casting concrete.Before building, the first shutoff bolt is screwed in taper pin with internal thread, concrete infiltrates in the screw of taper pin with internal thread when preventing from building.During use, the first shutoff bolt is turned on, the second shutoff bolt is screwed in the screw of taper pin with internal thread, utilize sealing ring to install towing point is provided for cable.After installation, the second shutoff bolt is backed out, again the first shutoff bolt is screwed in taper pin with internal thread, guarantee to walk unobstructed.When later stage cable is changed maintenance or is laid the cable in other loops, can repeat above-mentioned action, for cable, install towing point is provided.
The beneficial effects of the utility model are: earth anchor, without cutting, after cable laying completes, without cutting earth anchor, only need be backed out earth anchor top with spanner, covers shutoff bolt; Avoid operation dangerous, artificial spanner can be backed out earth anchor, without charged or band hazardous gas operation, does not also produce waste gas, waste residue or spark; Earth anchor is reused, and when later stage cable overhauls or lays other loops, still can utilize original earth anchor, has avoided the unnecessary construction that repeats.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, is convenient to be well understood to the utility model, but they do not form and limit the utility model.
A kind of cable tunnel earth anchor as shown in Figure 2 and Figure 3, it comprises the anchor plate 2 being embedded in concrete slab 1, the upper end of anchor plate 2 is fixedly connected with connecting rod 3, connecting rod 3 tops do not exceed the surface of concrete slab 1, connecting rod 3 offers screw vertically, screw is by seal shutoff, and seal and connecting rod 3 removably connect.
In the present embodiment:
Connecting rod 3 is taper pin with internal thread, before cable construction and after construction, seal for taper pin with internal thread in the height of the first shutoff bolt 4.1, the first shutoff bolts 4.1 of matching of screw after installing be no more than the surface of concrete slab 1; When cable construction, seal elect as with taper pin with internal thread in the second shutoff bolt 4.2, the second shutoff bolts 4.2 of matching of screw comprise shutoff screw rod 4.3, described shutoff screw rod 4.3 upper ends are provided with sealing ring 4.4.
