DETAILED DESCRIPTION

[0026] The present application is further described in detail below with reference to Figs. 1-2.

[0027] According to an embodiment of the present application, with reference to Figs.1-2, a method for constructing a large-span thin-walled concrete sound barrier with a pouring trolley includes the following steps. Step 1: constructing a base 9 on two sides of an existing road or railway; the base 9 is a concrete strip base 9, and is arranged along a length direction of the existing road. When pouring concrete of the base 9, a steel rail 91 is pre-embedded in the base 9. The spacing between 5 adjacent steel rails 91 is the same as the spacing between adjacent vertical columns 3 on the 501348 trolley. The steel rail 91 protrudes from a top surface of the base 9 to serve as a walking rail for trolley. Step 2: mounting a walking system on the base 9. The walking system is prepared in advance, and is hoisted on the base 9 in site. The walking system includes a connecting beam 4, walking wheels 7 and lifting jacks 83 that are mounted beneath the connecting beam 4. The walking wheels 7 are divided into active wheels and passive wheels. The active wheels and the passive wheels are distributed alternately. The active wheels are in a transmission connection with a driving motor that may be mounted on the connecting beam 4. One walking wheel 7 and two lifting jacks 83 constitute a walking system. In a walking system, the walking wheel 7 is positioned between two lifting jacks 83. Two mounting plates 82 are mounted beneath the connecting beam 4. Connecting plates 81 are fixed on two sides of the connecting beam 4 respectively. The connecting plate 81 is bolted to the mounting plate 82. A mounting space for mounting the lifting jack 83 is formed between two mounting plates 82. The lifting jack 83 is positioned between two mounting plates. One end of the lifting jack 83 is connected beneath the connecting beam 4, and the other end thereof is supported on the base 9. The connecting plate 81, the mounting plate 82 and the lifting jack 83 constitute a lifting assembly 8. The lifting assembly 8 can adjust the height of an arch frame 1. The mounting steps are as follows: hoisting a pre-assembled walking system, adjusting a position of a connecting beam 4 such that the walking wheel 7 fits with the steel rail 91; and adjusting a lifting jack 83 to support one end of the lifting jack 83 on the base 9 such that the walking wheel 7 separate from the steel rail 91 and the connecting beam 4 is raised.

[0028] Step 3: hoisting a truss system. The truss system includes arch frames 1, a connecting assembly 5 connecting adjacent arch frames 1, and two turn-over section 2 hinged to two ends of the arch frames 1 respectively. A plurality of arch frames 1 are uniformly arranged at intervals, and positioned in the same axis. At least two vertical columns 3 are fixed on the bottom of the 6 arch frame 1. The number of the vertical column 3 can be determined according to the span of 501348 the arch frame 1 and the spacing between adjacent vertical columns 3. In an example of the present application, three vertical columns 3 are provided, and a space for existing roads is formed between adjacent vertical columns 3. A hydro-cylinder 62 for supporting the turn-over section 2 is provided between a vertical column 3 and the turn- over section 2. One end of the hydro-cylinder 62 is hinged t the vertical column 3, and the other end is hinged with the turn-over section 2.

[0029] An arch frame 1 includes an arch crown 11, a transverse beam 12 that is arranged under the arch crown 11, in which two ends of the transverse beam 12 are both fixed on the arch crown 11, and a vertical rod 13 and a diagonal rod 14 that are arranged between the arch crown 11 and the transverse beam 12. The vertical rods 13 and the diagonal rods 14 are alternately arranged, a plurality of vertical rods 13 are evenly spaced and a plurality of diagonal rods 14 are arranged in a wavy shape. The vertical rods 13 and the diagonal rods 14 are used to increase the structural strength of the arch frame 1, so as to support the base formwork stably. The vertical column 3 1s fixedly connected with the crown 11 or the transverse beam 12. The turn-over section 2 is hinged with the arch crown 11, and the materials and specifications of the turn-over section 2 and the arch frame 11 are the same. A scissor brace 15 is fixed between adjacent vertical columns 3 of different frame arches 1 in the same row, so as to increase the integrity and supporting stability of the truss system.

[0030] A diagonal brace 16 is connected between the vertical column 13 and the transverse beam 12. One end of the diagonal brace 16 is fixed to the vertical column 3, and the other end is fixed to the transverse beam 12. 16 is provided between vertical columns 3 at two ends of the arch frame 1 and the transverse beam 12. Two diagonal braces 16 are provided between a vertical column 3 in the middle and the transverse beam 12, and the two diagonal braces 16 are symmetrically installed on both sides of the vertical column 3. The connection strength and support performance of the vertical column 3 and the arch frame 1 are increased by 7 using the diagonal braces 16. LU501348

[0031] The connecting assembly 5 includes connecting rods, which can be made of U-steel. The connecting rods are detachably connected, e.g., are bolted, between adjacent arch crowns 11 and between adjacent turn-over sections 2. The connecting rods are evenly arranged along the arc direction of the arch crown 11 and the turn-over section 2. Footboards are arranged on the connecting rods in an arc shape with an arch consistent with the arch crown 11. The footboards close the gaps between the adjacent arch crowns 11 and provide an accessible working platform for pouring the sound barrier.

[0032] The mounting steps are as follows: processing: connecting the transverse beam 12 under the arch crown 11; welding two ends of the transverse beam 12 to the arch crown 11; fixing vertical rods 13 and diagonal rods 14 between the arch crown 11 and the transverse beam 12 successively; a layout surveying is performed on the transverse beam 12 and the arch crown 11 to determine mounting positions of the vertical columns 3; bolting or welding the vertical columns 3 to the transverse beam 12 or arch frame 11; connecting diagonal braces 16 between the vertical columns 3 and the transverse beam 12; mounting turn-over sections 2 hinged with the arch crown 11; and connecting hydro-cylinders 62 between the turn-over sections 2 and the vertical columns 3.

[0033] After the arch frame 1 is processed, the arch frame 1 is transported to the construction site. The arch frame 1 is hoisted, and the vertical column 3 and connecting beam 4 are bolted for fixation. The lifting jack 83 and hydro-cylinder 62 are adjusted until the arch frame 1 and turn-over section 2 reach to the design elevation. The subsequent arch frames 1 are mounted successively by repeating the above process. After the arch frame 1 is mounted and adjusted, scissor braces 15 are mounted between adjacent vertical columns 3. A majority of arch frames are connected as a whole. The connecting rods are connected between adjacent arch frames 1, and the footboards are arranged on the connecting rods, so as to form a construction platform.

[0034] Step 4: mounting formworks: fixing a base mold of a primary beam of a sound barrier 8 to the arch crown 11; binding primary beam reinforcements; mounting side mould; pouring 31348 concrete; after the concrete is initially set, detaching the side mold firstly, and applying concrete curing solution for curing; after the concrete reaches the design strength, lowering the arch frame 1 by the lifting jack 83 and the hydro-cylinder 62, and detaching the base mold; continuously reducing the height of the lifting jack 83 , so that the walking wheels 7 contact the steel rail 91; and moving the trolley to the next construction position driven by the drive motor.

[0035] When the span of arch frame 1 is large, the transportation and hoisting thereof have high requirements for construction space and crane specifications, so that it is difficult to carry out construction on site. Therefore, each arch frame 1 is divided into two sections, and the two sections of arch frame 1 are bolted. During construction, one section of the arch frame 1 is hoisted and mounted firstly, and then the other section of the arch frame 1 is hoisted and mounted, so as to finish the connection of two sections of the arch frame 1. By providing two sections of the arch frame 1, on the one hand, the occupied space of the arch frame 1 is reduced, which facilitates the transportation and hoisting of the arch frame 1. On the other hand, the weight of the arch frame 1 is reduced, so that a crane can realize the hoisting of the arch frame 1.

[0036] Further, in order to facilitate the mounting of the trolley and the formwork, a gantry is provided outside the sound barrier, and the sound barrier is positioned inside a gantry. The components like connecting rods and footboards are hoisted by a hoisting equipment on the gantry. In addition, the formwork can be hoisted when mounting the formwork, which facilitates the construction.

The above are the preferred embodiments of the present application, which are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
