Description
Technical field
The present invention relates to Hydraulic and Hydro-Power Engineering equipment technical field, especially relate to a kind of used in vertical transportation of concrete buffer.
Background technology
In water conservancy and hydropower (underground) engineering construction, in order to be able to the most work surfaces carrying out concreting, generally connect tunnel work surface from ground and vertical shaft is set, vertical transport concrete mode is used to be operated the expansion in face, and use in vertical transport concrete construction, generally need to overcome the drop of hundreds of meter, in relatively high drop transportation, owing to concrete self exists gravity, transport can produce aggregate separated, the workability directly resulting in concrete can reduce, thus have a strong impact on the quality of concreting and pour effect.In Traditional project construction, buffer generally uses the My-Box buffer of Japan's import, construction experience is enriched, construction method is the most ripe, can effectively prevent the separation of aggregate in concrete transportation, buffer typically installs one 10～15m, but My-Box buffer is relatively costly, and material selection is the wear-resisting steel of high-quality, in used in vertical transportation of concrete, concrete self and buffer case and dividing plate direct friction, its abrasion is bigger, buffer need to be often changed when pouring generous amount concrete, considerably increase cost, have impact on the progress of construction, even have influence on the quality of concreting.
Summary of the invention
Instant invention overcomes shortcoming of the prior art, it is provided that a kind of expense is low, performance is high, easy and simple to handle, rapid buffer of constructing.The installation of this buffer can be constructed the most at the scene, simple in construction, install save time, laborsaving, service life is long, and cost of manufacture is low, can preferably improve concrete disintegration phenomenon, improves the workability energy of concrete.
In order to solve above-mentioned technical problem, the present invention is achieved by the following technical solutions: a kind of used in vertical transportation of concrete buffer, including:
One the first separator tube being vertically arranged, its lower end is blind end, and upper end upwardly extends to be formed and is provided with the ring flange connected on contraction mouth and contraction mouth；
The second separator tube that one structure is essentially identical with the first separator tube, it is arranged at the first separator tube side and setting direction is contrary with the first separator tube；
One is obliquely installed for connecting the first separator tube and the connecting tube of the second separator tube, and its one end being connected with the first separator tube is higher than the other end.
Preferably, described connecting tube and the blind end connecting nearly first separator tube of termination of the first separator tube, the other end is close to the blind end of the second separator tube.
Preferably, the blind end of described first separator tube and/or the blind end of the second separator tube are provided with suspension ring.
Preferably, described suspension ring use the round steel bending forming of diameter 25 millimeters.
Preferably, described first separator tube and the second separator tube are made up of the welding of Q300 welded still pipe.
Preferably, the bottom of described second separator tube is provided with the firmware fixing the second separator tube.
Preferably, described firmware is made up of channel-section steel.
Compared with prior art, present invention have the advantage that
The present invention has that expense is low, performance is high, easy and simple to handle, rapid advantage of constructing.The installation of this buffer can be constructed the most at the scene, simple in construction, install save time, laborsaving, service life is long, and cost of manufacture is low, can preferably improve concrete disintegration phenomenon, improves the workability energy of concrete.Through practice, buffer maximum spacing of the present invention can reach 43m and installed one, breaches far away the requirement of 10～15m one buffer of installation.This buffer is better than conventional buffer from technical feasibility, economy and reliability.In tunnel vertical transport concreting relatively more economical, be suitable for.
