Problems solved by technology

[0009] 3. The transverse / oblique fissure is close to the ring shape, and the width of the residual crack exceeds 0.5mm, or the length exceeds 2 / 3 of the occipital height
[0010] 4. The shoulder is damaged, close to losing its support ability, and the damaged length exceeds 1 / 2 of the length of the shoulder
[0011] 5. Severely dropped blocks, exposed tendons, unable to repair
[0051] 3. Resources and waste
In fact, the use of waste concrete sleepers around the railway project is very limited, and the large amount of waste concrete sleepers newly added every year cannot be consumed on both sides of the railway, so a large number of waste concrete sleepers are discarded along the line or smashed on the spot to take steel bars, causing huge resource waste and environmental pollution

[0139] Example 1: Design of Standard Parts for the Foundation of Residential Buildings in Small Towns

[0140] 1. Calculation of floor load for residential buildings in small towns:

[0141] Calculation example 1: Assume that the floor height of a small town is 3m, the bay is 3.9m, the thickness of the hollow clay brick wall is 240mm, and the volume density of the hollow clay brick wall is 16kN / m 3 , the inner and outer walls are finished with cement mortar, the thickness of the finish is 17mm, and the bulk density is 20kN / m 3 ;The buried depth of the foundation is 1.2m, and the average bulk density of foundation and soil is 20kN / m 3 ; Floor slab bulk density 20kN / m 2 , floor finish 0.7kN / m 2 , floor finish 0.24kN / m 2 ; Roof surface waterproof layer, insulation layer and other dead load 1.8kN / m 2 ; Roof live load 0.5kN / m 2 , floor live load 2.0kN / m 2 ; The allowable bearing pressure of the foundation soil is strong [f A 〕=100kN / m 2 . Take the 1m length of the strip f...

[0166] Example 2: Fundamental design of the translation and direction engineering of the office building of Xinxiang Rongtai Lock Factory

[0167] The office building of Xinxiang Rongtai Lock Factory is located in the southern suburb of Xinxiang City. Due to the widening of the road, it needs to be diverted 90 degrees in situ.

[0168] A brief description is as follows:

[0169] 1. General situation of the office building: three floors, brick-concrete structure, solid clay bricks, 4m bay, 6 rooms, 3.5m story height, construction area 700 square meters, see the plan and foundation diagram for relevant dimensions. The foundation is silt, the standard value of bearing capacity f k =80kpa, strip foundation, concrete foundation cushion C 10 , base C 15 , others are C 20 . The longitudinal wall foundation B=2.1m, the transverse wall foundation B=1.5m.

[0170] 2. Foundation design: For translation and orientation engineering, the building should be rotated and adjusted on the ...

Abstract

The invention is a re-making method of the waste concrete sleeper, which is an artificial zoological technology combining the small towns along the railways and the track repairing system. The method has become the basic standard piece of construction and is widely suitable for the building of 1-6 floors. The system provides the technological scheme to solve the pollution problem of the concrete sleeper, to save the resources and to protect the environment.

Description

Technical field: [0001] The invention belongs to the field of civil engineering, and in particular relates to a method and product for remanufacturing railway waste concrete sleepers --- building foundation standard parts. Background technique: [0002] When we go out to enjoy the scenery along the way by train, there are plastic lunch boxes, plastic bags, and abandoned concrete sleepers floating along the railway line, which is always a bad sight. Plastic lunch boxes are called "white pollution". The railway department has invested a lot of manpower and material resources to promote bagged garbage and pulp lunch boxes. At present, "white pollution" has been basically curbed; Public nuisance, there is still no good solution so far; the pollution of waste concrete sleepers along the railway has not yet attracted widespread attention. On both sides of the line, the railway department uses waste pillows as the slag retaining wall of the track bed of the railway line, lays the ...
