Concrete prefabricated block quick dumping structure and dumping method

Abstract

A structure and method for rapid dumping of prefabricated concrete blocks. In the past, dumping barges had low utilization rates for carrying capacity and required multiple round trips for loading and unloading, which took a long time, was inefficient, required a large number of personnel, and had high labor costs. At the same time, an additional forklift was required, resulting in high overall costs. The present invention comprises: a positioning ship (1) and a dumping barge (5), wherein a generator (3) and two winches (2) are installed in front of the cabins of the positioning ship and the dumping barge, and four supports (7) are made on the longitudinal sides of the hulls of the positioning ship and the dumping barge, and a guide pulley (9) is installed on each of the supports. The steel wire rope of the corresponding side winch passes through the pulley and is finally fixed to the pillar at the stern. The present invention is used for rapid dumping of prefabricated concrete blocks.

Description

Technical Field

[0001] The invention relates to a quick dumping structure and method for prefabricated concrete blocks. Background Art

[0002] The project technicians and filling personnel calculate how many prefabricated blocks are needed to be placed on the surface of the ship per unit area within the effective length of the barge (the length after deducting the length occupied by the barge's own boatman's house and the hoist and generator configured at the back) and how to place them to achieve the design per unit area of ​​the corresponding position on the side of the ship. The filling barge is installed according to this quantity and placement requirements. The filling ship places the filling concrete prefabricated blocks within the three-meter width of the ship's side, and a small number of prefabricated blocks are stored in the remaining width, which is used as a forklift to transport, place prefabricated blocks, and a 50 forklift for filling. The filling barge is pushed to the predetermined filling position by the push wheel and leans against the positioning ship waiting at this position in advance. The positioning ship is equipped with a GPS positioning system, which has accurately determined the filling position according to the design by the GPS positioning system before the arrival of the filling ship.

[0003] After the dumping barge approaches the positioning ship, workers lock the dumping barge and the positioning ship with ropes. The blocks are placed by a clamp forklift, and the forklift repeatedly walks in the vacant area, pushing the prefabricated blocks in different positions into the river again and again. After the whole ship is pushed, the prefabricated blocks are loaded on the shore.

[0004] Its disadvantages are: the utilization rate of the dump barge's carrying capacity is low (most of the space is used for the forklift working surface and cannot be fully used to pull prefabricated blocks), multiple round trips for loading and unloading are required, which takes a long time, is inefficient, requires a large number of personnel, and has high labor costs; at the same time, an additional forklift is required, which has high overall costs. Summary of the invention

[0005] The purpose of the present invention is to solve the problems of low utilization rate of the carrying capacity of the dumping barge, multiple round trips for loading and unloading, long time, low efficiency, large number of personnel required, high labor cost, and the need for an additional forklift, which has high comprehensive cost. A concrete prefabricated block rapid dumping structure is provided, which utilizes the deck space and loading capacity of the barge to improve efficiency and reduce costs.

[0006] The above purpose is achieved through the following technical solutions:

[0007] A concrete prefabricated block rapid dumping structure comprises: a positioning ship and a dumping barge, wherein a generator and two winches are installed in front of the cabins of the positioning ship and the dumping barge, four supports are made on the longitudinal sides of the hulls of the positioning ship and the dumping barge, and a guide pulley is installed on each of the supports, and the steel wire rope of the corresponding side winch passes through the pulley and is finally fixed on the pillar at the stern.

[0008] The concrete prefabricated block rapid dumping structure, the positioning ship has a winch installed at each of the four corners of the hull, the steel wire rope of the winch is about 45 degrees to the sideline of the ship, and is connected to an anchor point 100-150 meters away.

[0009] The concrete prefabricated block rapid dumping structure, the positioning guide device includes a column and a guide column, the upper and lower ends of the column are respectively sleeved with connecting plates and fixed to the connecting plates, and the guide column is fixed between the two connecting plates.

[0010] A method for quickly filling a concrete prefabricated block structure, the method comprising the following steps: first, before filling, the construction technicians collect relevant data from the work area through accurate topographic maps, bathymetry and hydrographic surveying methods. The measurement of layer thickness is usually based on the horizontal elevation before and after the placement of the specified material. In dry places, post-work leveling can be performed by installing a hemispherical leveling rod with a diameter of 200mm at the bottom of the leveling rod. The thickness of the fill should usually be measured on a straight line 5m apart along the slope of the revetment project and recorded at intervals of one meter on each straight line. For underwater measurement, Eco Sounding and DGPS with sufficient accuracy will be used for hydrographic survey to determine the layer thickness;

[0011] Then, the dumping personnel will calculate how many prefabricated blocks need to be placed per unit area of ​​the ship surface according to the design drawings and the size and load tonnage of the dumping barge on both sides of the dumping barge. How to place them to achieve the design usage per unit area of ​​the corresponding positions on both sides of the ship. The effective length refers to the length after deducting the length occupied by the barge's own boatman's house and the windlass and generator configured later. The dumping barge is installed according to this quantity requirement and placement requirement. The dumping barge is pushed to the predetermined dumping position by the pusher and leans against the positioning ship waiting at this position in advance. The positioning ship is equipped with a GPS positioning system. Before the dumping ship arrives, the dumping position has been accurately determined by the GPS positioning system and the windlass according to the design;

[0012] Four one-meter-long supports are provided on the side of the connection between the positioning ship and the dumping ship to ensure that there is a one-meter distance between the dumping ship and the positioning ship. Pulleys are installed on these four supports, and the wire rope passes through the pulleys. When dumping, the dumping block is divided into three sections;

[0013] After the dumping barge approaches the positioning ship, workers lock the dumping barge and the positioning ship with ropes, pry open a gap of about 3 centimeters at the designed dumping block with a crowbar, put the wire rope in, start the winch, and dump the designed amount of prefabricated blocks into the designated position in the river in batches according to the distance between the supports on both sides of the dumping barge at irregular intervals. After throwing one meter on each side, the positioning ship moves to the next position by the winch according to the instructions of the GPS positioning system and continues to dump prefabricated blocks. After one ship finishes throwing, the next dumping ship comes over and repeats the above process.

[0014] Beneficial Effects

[0015] 1. The present invention fully utilizes the deck space and loading capacity of the barge, achieving the purpose of improving efficiency and reducing costs, and the whole system is easy to operate, easy to construct, and fast. Practice has proved that the use of forklift dumping equipment is reduced, the dumping time is saved, the work efficiency is improved, the construction cost is reduced, and the project benefits are increased.

[0016] 2. The present invention uses a steel wire rope to throw out the prefabricated blocks, which does not require the use of a forklift, can improve work efficiency and save throwing and filling time. BRIEF DESCRIPTION OF THE DRAWINGS
