Description
Technical field
The present invention relates to transformer station's inner cable ditch manufacturing and construction method thereof, particularly prefabricated assembled cable trench manufacturing and construction method thereof.
Background technology
At present, the common practice of transformer station's cable trough has two kinds: a kind of is brick setting surface plastering cable trough; Another kind is the cast-in-place concrete cable trough.Along with the continuous development of power engineering, the requirement of duration, safety construction is improved constantly, above two kinds of cable troughs showed its shortcoming:
1) above-mentioned two kinds of cable trough site operation operation procedures are various, long in time limit, and resource cost is bigger, cause on-the-spot chaotic and potential safety hazard increase, and management difficulty strengthens, and is unfavorable for carrying out of safety construction;
2) cost of above-mentioned two kinds of cable troughs all is higher than prefabricated assembled cable trench, according to 1 meter cable trough measuring and calculating, about 700 yuan/meter of the cost of brick surface plastering ditch body, about 900 yuan/meter of armored concrete cable trough cost;
3) Comparatively speaking, brick cable trough is because brick technological requirement of plastering is higher, and the quality of plastering is generally on the low side, occurs common quality defect easily; Then there is the formwork difficulty in the cast-in-situ steel reinforced concrete cable trough, and ditch body concrete surface smoothness is difficult to guarantee;
4) globality of brick cable trough and less stable normal occur tilting, collapse, problem such as distortion;
5) advocate " amphitypy one is changed " according to state net company, i.e. resource-conserving, environmentally friendly, industrialization demands, carrying out prefabricated assembled cable trench will be the development in future direction.Above-mentioned two kinds of cable troughs are because resource cost is many, and the situ wet operation procedure is many, long in time limit, safety construction is poor, can not adapt to the needs of current power engineering development.
Summary of the invention
The prefabricated assembled cable trench that the purpose of this invention is to provide a kind of manufacturing simple in structure, convenient, convenient construction.
The object of the present invention is achieved like this: a kind of prefabricated assembled cable trench, form by pre-fabricated electric cables ditch monomer, the section of each cable trough monomer is " U " font ditch body, and left and right furrow bank symmetry and left and right furrow bank shrink gradually from the bottom to top and narrow down, and the arc-like rows tank is arranged at ditch body bottom.
The length of above-mentioned cable trough monomer is 1m.
Be embedded with the reinforcing bar suspension ring on the above-mentioned cable trough monomer.
Another object of the present invention provides a kind of installation method of prefabricated assembled cable trench, and its installation method is as follows:
A), the ditch body is installed on the thick plain concrete soil padding of 100mm shop 30～50mm dry cement mortar leveling during installation, ditch body employing crane lifting installation; During installation, reserve the 5mm slit between adjacent two cable trough monomers, adopt the waterproof mortar cementation of fissures, jointing;
B), cable bearer directly is fixed on the furrow bank with punching bolt and expansion bolt, the ground connection band steel is placed on the punching bolt, card is pressed between support and the furrow bank when support is installed, both sides and support welding;
C), cable trough corner and T connector place ditch body adopt the brick ditch body of plastering.
Compared with prior art, the invention has the beneficial effects as follows:
1, prefabricated assembled cable trench has solved existing brick formula and the numerous and diverse problem of armored concrete formula cable trough wet trade program of plastering, and has the advantages that the construction period is short, save resource, easy construction.
2, the manufacturing cost of prefabricated assembled cable trench is only 600 yuan/meter, has the low advantage of cost.
3, compare with brick formula cable trough, the present invention has good integrity and advantages of high strength.
4, prefabricated assembled cable trench bottom of trench surfacing is beneficial to and drains the water away, and has solved the common fault of bottom of trench ponding well.
Description of drawings
Fig. 1 is the schematic perspective view of the assembly unit of two pre-fabricated electric cables ditch monomers;
Fig. 2 is the front view (rhone and cable bearer etc. are shown) of pre-fabricated electric cables ditch monomer shown in Figure 1.
Embodiment
Fig. 1 illustrates, the present invention is made up of pre-fabricated electric cables ditch monomer, the section of each cable trough monomer 1 is " U " font ditch body, ditch body internal orifice is wide at the top and narrow at the bottom, the left and right furrow bank section of ditch body is up-narrow and down-wide, left and right furrow bank symmetry and left and right furrow bank shrink gradually from the bottom to top and narrow down, and arc-like rows tank 1a is arranged at ditch body bottom.The length of cable trough monomer is 1m.Be embedded with the reinforcing bar suspension ring on the cable trough monomer.
Referring to Fig. 2, a kind of installation method of prefabricated assembled cable trench, carry out according to the following steps:
A), the ditch body is installed on the thick plain concrete soil padding of 100mm shop 30～50mm dry cement mortar leveling during installation, 8 tons of cranes liftings of ditch body employing installation; During installation, reserve the 5mm slit between adjacent two cable trough monomers, adopt the waterproof mortar cementation of fissures, jointing;
B), cable bearer 2 usefulness punching bolts 4 and expansion bolt 5 directly be fixed on the furrow bank, ground connection band steel 3 is placed on the punching bolt, card is pressed between support and the furrow bank when support is installed, both sides and support welding;
C), cable trough corner and T connector place ditch body adopt the brick ditch body of plastering.
The invention reside in the deficiency that solves the traditional cable ditch design of current transformer station, construction, take a kind of novelly, meet the assembly type cable slot that state net company " amphitypy one is changed " requires.
Its design feature, method for prefabricating and mounting process are as follows:
1, on this cable duct Cross section Design, be aspect form removal and economical with materials when prefabricated, ditch body inboard is designed to type wide at the top and narrow at the bottom, and the external side of ditch is designed to up-narrow and down-wide type, and furrow bank shrinks gradually from the bottom to top and narrows down. In the middle of the cable slot body bottom, the dark arc draining of the wide 20mm of 50mm sulculus is set, can strengthens the bottom of trench drain function, reduce bottom of trench ponding. Consider that simultaneously lifting and transhipment are convenient, be symmetrical arranged the reinforcing bar suspension ring at furrow bank.
2, this prefabricated assembled cable trench template adopts punching block to make, and the size that can measure is according to demand made many cover templates.
3, the ditch body reaches and is transported to the scene with machinery after the intensity and installs successively. Bottom of trench places on the C15 concrete cushion, and bottom of trench is straight according to the drainage grade leveling with the dry cement mortar. Consider that cable duct belongs to outdoor structures, be subjected to atmospheric effect bigger, do not use the caulking joint of organic waterproof material, joint filling in durability and anti-aging, the waterproof mortar cementation of fissures, jointing are adopted in the slit between the ditch body.
4, installing cables support and grounding flat steel. Need to perforate on furrow bank, available professional hole making drill operation.
