Problems solved by technology

[0002] In the process of bridge construction, the anchorage of the anchor generally adopts the section steel anchorage system and the prestressed anchorage system. Although the section steel anchorage system uses a large amount of steel, requires high precision in manufacturing, installation and construction, and requires a large amount of work, the system does not require post-maintenance. , no need for later investment, it is a one-time investment and permanent use type. Therefore, from the perspective of the whole life of the bridge, the section steel anchorage system has a strong advantage over the prestressed anchorage system, but the anchor b

Embodiment 1

[0043] An anchorage system construction method, including the following steps:

[0044] (1) Step 1. Construction of sunk well cover:

[0045] 1) Pouring the caisson well cover, reserve the anchor beam bracket installation position 1 above the poured manhole cover, such as figure 1 As shown, after the caisson cover is poured, the two sides of the anchor beam support installation site 1 are the anchor beam support step area 2 and the anchor support step area 11 respectively, and the anchor support step area 11 is divided into the middle anchor support area 111 and the step area 112 of the anchor rod bracket on the front anchor surface, such as figure 1 , 3, 4; the reserved anchor beam bracket installation site 1 distinguishes different areas after the manhole cover is poured, so as to form a hybrid support system in the later construction; in this embodiment, the method of pouring the caisson manhole cover is a technology in the art The common knowledge and common methods of personne...

Embodiment 2

[0096] Based on the above embodiment 1, as figure 1 As shown, in the first step, the caisson manhole cover is constructed, and the caisson manhole cover is poured in blocks and layers. According to the requirements of temperature control, the manhole cover is poured in blocks and layers, which can prevent the manhole cover from cracking. In this embodiment, other undescribed contents are the same as the foregoing embodiment, and will not be repeated here.

Embodiment 3

[0098] Based on the above embodiment 1, as Figure 5-9 As shown, the anchor block concrete layer 3 has the same height except for the last layer. The height of each layer customized according to the concrete pouring template is the same. Therefore, the construction height of each layer of the anchor block concrete layer 3 is the same, and there is no need to adjust each time, which is convenient for construction. In general, the height of each floor of the customized concrete pouring formwork is 3m. In this embodiment, other undescribed contents are the same as the foregoing embodiment, and will not be repeated here.

Abstract

The invention discloses a construction method of an anchorage anchoring system. The construction method comprises the following steps of (1) constructing a well cover of a sinking well; (2) pouring concrete in a step area of an anchor beam bracket layer by layer; (3) installing the anchor beam bracket; (4) installing an anchor beam and an anchor rod bracket; (5) installing anchor rods and pouringanchor block concrete layers one by one; (6) continuing anchor block construction. According to the construction method, a mixed anchoring bracket system is formed, and a construction mode of installing the anchor rods during pouring is adopted at the same time. According to the method, the mixed anchoring bracket system is formed, the rigidity of the anchoring bracket is enhanced correspondingly,the cumulative deformation effect is eliminated, repeated operation caused by deformation of the bracket is effectively prevented, the construction efficiency is improved, the use amount of section steel is reduced, and the input cost is reduced.

Description

Technical field [0001] The invention relates to the field of bridge construction, in particular to a construction method of an anchorage system. Background technique [0002] In the process of bridge construction, the anchorage of anchorage generally adopts section steel anchor system and prestressed anchor system. Although section steel anchor system uses a large amount of steel, requires high production, installation and construction accuracy, and has a large amount of work, the system does not require post-maintenance It is a one-time investment and permanent use type without later investment. Therefore, from the perspective of the full life of the bridge, the section steel anchoring system has a strong advantage over the prestressed anchoring system, but the anchoring bracket of the section steel anchoring system generally adopts steel structure , Installed in place one by one, however, during the installation process of the section steel anchoring system, the steel structure...
