Construction system for conveying mortar by long distance to fill sand bags

Abstract

The invention relates to a construction system for conveying mortar by long distance to fill sand bags. The construction system comprises a sand bin, a high-pressure water flow divider, a plurality ofsilt pumps and a confluence device are arranged in the sand bin, the high-pressure water flow divider comprises a water tank, a plurality of water flow division branch pipes are arranged on the sidewall of the water tank, an inlet of the water tank is connected to an outlet of one water pump through a water delivery main pipe, a water division pipe is connected to each water flow diversion branch pipe, a high-pressure water gun is connected to each water division pipe, the confluence device comprises a confluence box body, a plurality of confluence branch pipes are arranged on the side wallof the confluence box body, a water supplementing branch pipe and an outer discharging branch pipe are arranged on the front wall of the confluence box body, the construction system further comprisesa relay pump and a sand blowing flow divider, the sand blowing flow divider comprises a sand flow division box body, a plurality of sand flow division branch pipes are arranged on the side wall of thesand flow division box body, the outlet of the confluence box body of the confluence device is connected to an inlet of the relay pump through a mortar pipeline. According to the construction system,the mortar concentration is controllable, mortar conveying is smooth, pipe blocking accident of a conveying pipeline is avoided, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of dredging equipment, in particular to a construction system for long-distance transporting mortar and filling sand bags. Background technique [0002] In the construction of hydraulic engineering, large sand-filled bags are widely used in revetment projects, rivers, and cofferdam projects, and are used as embankment cores. Domestic sand bag filling construction mainly uses sand blowing ships (equipped with high-pressure water guns and mud pumps), and sand barges are used to dock to the sand blowing ships equipped with high-pressure water guns and mud pumps, and then the sand in the barge is blown and filled to a fixed position manually. in the sandbag. However, the water depth of the project is relatively shallow, and the terrain is uneven, and there is a risk of grounding when transported by sand barges, so this method is not suitable for projects with relatively shallow water depth. The method of singl...

Problems solved by technology

[0003] Internationally, under the condition of long blowing distance, sand bag filling is usually carried out by self-modified ships. Two large funnels are installed on ordinary large bulk carriers, and the belt sand is directly blow-filled to the construction area, which can be used for sand cushion blow-fill It can also be used for filling bags. This equipment can effectively overcome the shortcomings of long blowing distance and large wind and waves, but the cost is expensive.

[0004] In order to overcome the long-distance filling distance, uncontrollable mortar concentration, difficulty in mortar transportation, resulting in blockage of transportation pipelines and serious reduction in work efficiency, it is necessary to develop and design a construction process system for long-distance transportation of mortar and filling sand bags to achieve efficient and fast. Mortar transportation greatly improves the production efficiency of sand-filled bags, which is of great significance to engineering construction
