Abstract
The utility model provides a sector-shaped concrete building block of a masonry shaft. The building block is sector-shaped, a sector-shaped angle beta ranges from 43 degrees to 45 degrees, and two grooves are correspondingly designed on each side surface of the building block. A U-shaped groove can be designed on a sector-shaped surface further. The sector-shaped concrete building block resolves problems of resource waste, lower efficiency, uncontrollable quality and the like caused when building shafts with common fired clay bricks conventionally.
Description
Technical field
The utility model relates to the concrete block that the municipal drainage engineering is built pit shaft by laying bricks or stones.
Background technology
The circular manhole of the upper and lower water conservancy project journey of existing municipal engineering need use a large amount of clay bricks, and speed of application is slow; Construction quality is difficult to guarantee, influenced greatly by workman's operant level; The cost height, the mortar consumption is big; Usually produce a large amount of brickbats, the wasting phenomenon especially severe; Skilled worker's level is required height, and the speed of building by laying bricks or stones is slow.
Summary of the invention
The purpose of this utility model provides a kind of fan-shaped concrete block of building pit shaft by laying bricks or stones, has solved traditional common brick and has built problems such as the wasting of resources, efficient that pit shaft brings easily are lower, quality is wayward by laying bricks or stones.
The technical solution of the utility model is: a kind of fan-shaped concrete block of building pit shaft by laying bricks or stones, it is characterized in that described building block is fan-shaped, and fan-shaped angle beta is 43～45 degree, corresponding respectively design has 2 grooves on each side of building block.
Wherein can also on a sector, design U type groove is arranged.
Build pit shaft by laying bricks or stones with traditional loam brick and compare, use the belt piece of composite material concrete to build manhole by laying bricks or stones and have following advantage:
Can replace clay brick, satisfy the requirement of strength of common brick fully, speed of application is very fast; Insert the arm (comparing) of different tube diameters, buried depth easily with prefabricated pit shaft; Construction quality guarantees that easily it is less influenced by workman's operant level; Cost is low, and the mortar consumption obviously reduces, than reducing by 30% with traditional brick pit shaft; No brickbat produces, and eliminates wasting phenomenon, has protected construction environment, and is consistent with the policy energy-saving and cost-reducing, the protection environment of country, has environment-friendly advantage; Skilled worker's level is required to reduce, and the speed of building by laying bricks or stones is obviously accelerated, and can improve work efficiency 25%.
It is building by laying bricks or stones of 700mm circle manhole that this fan-shaped building block can be used for the upper and lower water conservancy project journey of the municipal engineering diameter that institute has or not specific (special) requirements.
Description of drawings
Fig. 1 is one of structural representation of the present utility model.
Fig. 2 is two of a structural representation of the present utility model.
Fig. 3 is a The field schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 3, the upper and lower water conservancy project journey of municipal engineering diameter is that the circular manhole 4 of 700mm needs to use 8 fan-shaped building blocks 1, and as shown in Figure 1 and Figure 2, fan-shaped angle beta is 43～45 degree, corresponding respectively design has 2 grooves 2 on each side of building block, and the waterproofing mortar that is beneficial to wipe one's face is bonding.
Because the design has considered the cat ladder installation, in the part building block, reserved the cat ladder position, be the U type groove 3 among Fig. 2, only need directly to place cat ladder in building by laying bricks or stones and get final product, so before construction, just should calculate required special blocks quantity and installation site in installation cat ladder position.
Claims (2)
1. a fan-shaped concrete block of building pit shaft by laying bricks or stones is characterized in that described building block (1) for fan-shaped, and fan-shaped angle beta is 43～45 degree, and corresponding respectively design has 2 grooves (2) on each side of building block.
2. a kind of fan-shaped concrete block of building pit shaft by laying bricks or stones as claimed in claim 1 is characterized in that design has U type groove (3) on a sector.
