Counterweighting and unloading automatic adjusting system for closure section construction and construction adjusting method thereof

Abstract

The invention relates to a counterweighting and unloading automatic adjusting system for closure section construction. The automatic adjusting system comprises a plurality of counterweighting water tanks, a plurality of pressure sensors, two water pumps, a flow velocity measuring and calculating instrument, and a control device, wherein the plurality of counterweighting water tanks are symmetrically arranged on the two sides of a closure section, the total weight of the single-side counterweighting water tanks is equal to half of the total mass of a pouring concrete of the closure section whenthe single-side counterweighting water tanks are counterweighted, and water outlet pipeline holes are formed in the counterweighting water tanks; the plurality of pressure sensors are uniformly distributed at the bottoms of the counterweighting water tanks; each of the two water pumps is arranged at the bottom of one counterweight water tank on the each of two sides of the closure section, the water pumps are connected with water outlet pipes, and the water outlet pipes penetrate through the water outlet pipeline holes and extend out of the counterweight water tanks; the flow velocity measuring and calculating instrument is arranged at a pipe opening of a concrete pump; and the control device is electrically connected with the plurality of pressure sensors, the two water pumps and the flow velocity measuring and calculating instrument. The invention further discloses a construction adjusting method which applies to the above automatic adjusting system for counterweighting and unloading on the two sides of the closure section. The automatic adjusting system ensures that the concrete pouring weight and the counterweighting and unloading weight are kept accurate and synchronous, andsolves the problem that the counterweighting and unloading speed are unbalanced due to the fact that drainage valves are arranged at the bottoms of water tanks in the traditional process.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an automatic counterweight unloading control system for closing section construction and a construction adjustment method thereof. Background technique [0002] In recent years, with the rapid development of the country, the level of transportation network planning has become higher and higher, and the geographical scope has become larger and larger. The construction of a large number of transportation infrastructure such as expressways and high-speed railways is also developing rapidly. The route engineering construction of these infrastructures often needs to cross winding gullies, rivers, etc., and the piers of bridges are getting higher and higher, especially in remote mountainous areas. This phenomenon is particularly obvious in the construction of long-span bridges. Significantly increased. In order to solve the technical problems of large span and high requi...

AI Technical Summary

Problems solved by technology

[0003] An object of the present invention is to provide an automatic counterweight unloading control system for the closing section construction, which can solve the problem in the prior art that the counterweight unloading error at the construction site of the closing section is relatively large and seriously affects the construction quality of the closing section
