Abstract
The present invention relates to a cable protecting tube block which comprises a block body in which a plurality of through holes are arranged. The present invention is characterized in that a bell and spigot is arranged at one end of the block body, and the bell and spigot is matched with the tail end of the block body of another cable protecting tube block. The block body is a podetium which can be a cylinder or a square podetium. The bell and spigot is in a truncated cone shape or a square frustum shape. The cable protecting tube block is made from cement, sand, carpolite, alkali-resistant glass fibers, wooden calcein and synthetic fibers of CTA Fidev. The present invention has the advantages of convenient connection, good sealing performance, little possibility of penetration of shallow ground water, light weight, small size, high intensity, aging resistance, infiltration prevention and corrosion resistance.
Description
Technical field
The present invention relates to a kind of cable tube block, particularly a kind of cable tube block that has bell and spigot.
Background technology
Along with further going deep into of urban renewal, it is imperative that three-way (illumination, phonovision, guard monitor etc.) replace three-way sky to establish with going into.Be the protection cable, generally all with cable laying in cable tube block.At present, generally adopt concrete plumber block or polyethylene pipe.Concrete plumber block large body and heavy mass, the installation and transportation inconvenience, strict to managing base, the cost height, non-watertight, perishable.And polyethylene pipe intensity is low, is subject to the excavation infringement of mouse and city, and coefficient of safety is low.
Summary of the invention
The objective of the invention is to overcome the defective that prior art exists, provide a kind of easy to connect, favorable sealing property, the light weight body is little, intensity is high, ageing-resistant, impermeable, erosion resistant cable tube block.
In comprising, cable tube block of the present invention is provided with the block of several through holes, one end of described block is provided with bell and spigot, the tail end of described bell and spigot and another cable tube block block is complementary, it is characterized in that described block made by the following weight proportion raw material: 1 part of cement, husky 0.67-1 part, grain of rice stone 0.5-1.5 part, alkali resistant glass fiber 0.02-0.05 part, wooden calcium flavin 0.01-0.03 part, Kai Tai (CTA) fiber 0.01-0.03 part, water cement ratio=0.3-0.4.
Cable tube block of the present invention, wherein said block is a square body, is provided with four or six through holes in it.
Cable tube block of the present invention, wherein said bell and spigot are square cone or truncated cone.
One of advantage of the present invention is easy to connect, and sealing is good.Therefore phreatic water is difficult for infiltrating plumber block, and cable is played a very good protection.Compared with prior art, the present invention ties up cable tube block tube wall book, and its pipe thickness is 1/3rd of a concrete plumber block; Light weight, proportion are 1.6-1.8T/m
3, than concrete 2.1-2.2T/m
3Light 0.4-0.5T/m
3, therefore less demanding to managing base, need only original soil rammed, " pseudo-ginseng " dirt is done pad soil, greatly reduces foundation cost; Because glass fibre evenly distributes, can prevent surface checking, stress is disperseed, so without reinforcing bar but the intensity height; Ageing-resistant; Impermeable; Because volume is less relatively, so need only excavate less pipe trench during construction and simple ditch base is handled, the pipe trench after the covering can be done track or plantation, has improved the utilance on ground greatly.
Description of drawings
Fig. 1 is the sectional view of the cable tube block in the present invention six holes;
Fig. 2 is the C-C profile of Fig. 1;
Fig. 3 is the B-B profile of Fig. 1;
Fig. 4 is the sectional view of the cable tube block in the present invention four holes.
Embodiment
Below in conjunction with drawings and Examples in detail the present invention is described in detail.
Fig. 1-cable tube block shown in Figure 3 comprises block 1, and an end of described block 1 is provided with bell and spigot 2.Bell and spigot 2 is a square cone.Block 1 is a square body, is axially arranged with six through holes 3 that size is identical in it, divides two rows to arrange, and is used to hold cable.Block also can be a cylinder.Generally speaking, the cylinder cable tube block is difficult to moulding, and the square body cable tube block is easy to moulding.So the square body cable tube block is a preferred version.
Be axially arranged with four through holes 3 that size is identical in the cable tube block block 1 shown in Figure 4, other is identical with Fig. 1-cable tube block shown in Figure 3.
During connection, earlier with of the surperficial evenly brushing twice of building TG glue, with the disconnected bell and spigot 2 that inserts of tail at bell and spigot 2 and adjacent cable plumber block block tail end; Fill space between the two, tamping at twice, moulding with TG glue and low alkalinity cement rubber cement again; Treat to smear twice and roll smooth getting final product on the filler surface with TG glue and low alkalinity cement rubber cement again after the interface initial set.
