Embodiment 1

[0032] see Figure 1 to Figure 3 As shown, this embodiment provides an anchor block structure, including a left anchor block 101 and a right anchor block 102, and a post-cast section 107 is arranged between the left anchor block 101 and the right anchor block 102; The inside of the block 101 is provided with an empty bin 103, and the top of the empty bin 103 is provided with a counterweight top plate 104; the right anchor block 102 is a solid structure, and the upper surface of the counterweight top plate 104 and the upper surface of the right anchor block 102 are used to form an approach bridge abutment foundation.

[0033] The anchor block structure provided by this embodiment is provided with the left anchor block 101 and the right anchor block 102, and the empty compartment 103 is set inside the left anchor block 101, while the right anchor block 102 is a solid structure. A balance weight top plate 104 is set above 103, which can not only balance the lateral counterweight...

Embodiment 2

[0046]This embodiment provides a construction method for an anchor block structure, which is used to construct the anchor block structure provided in Embodiment 1 of the present invention, which includes the following steps:

[0047] Layered and block-by-block construction of the left anchor block 101 and the right anchor block 102;

[0048] Formwork system construction of the left anchor block 101 and the right anchor block 102;

[0049] Concrete pouring construction of the left anchor block 101 and the right anchor block 102;

[0050] Carry out the construction of balance weight top plate 104 above empty warehouse 103;

[0051] Post-cast section 107 construction.

[0052] Optionally, in some embodiments, before the layering and block construction of the left anchor block 101 and the right anchor block 102, the foundation pit excavation and cushion construction steps are also included, and the foundation pit excavation is completed. Immediately after that, pour a concrete ...

Abstract

The invention relates to the technical field of building construction, in particular to an anchor block structure and a construction method thereof. The anchor block structure includes the left anchor block and the right anchor block. There is a post-casting section between the left anchor block and the right anchor block; The anchor block is a solid structure, and the upper surface of the balance weight top plate and the upper surface of the right anchor block are used to form the abutment foundation of the approach bridge. The anchor block structure and construction method provided by the present invention, by setting the left anchor block and the right anchor block, and setting an empty warehouse inside the left anchor block, the right anchor block is a solid structure, and at the same time, a The balanced weight top plate can not only balance the horizontal counterweight of the anchor body, but also reduce the amount of concrete on the premise of ensuring that the self-gravity of the anchor block structure can bear and balance the huge tension of the cable, and can also increase the load-bearing capacity above the empty warehouse, making the balance The upper surface of the heavy top plate and the right anchor block can be used as the abutment foundation of the approach bridge.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an anchor block structure and a construction method thereof. Background technique [0002] The suspension bridge mainly includes four parts: the main girder, the tower pier, the cable and the anchorage. Among them, the anchorage is the main load-bearing structure of the suspension bridge and the key part of the anchorage of the main cable of the suspension bridge. Its main function is to transfer the tension of the main cable to the foundation. . Among them, the gravity anchor is to use the friction force to balance the horizontal component of the tension of the main cable. Therefore, the gravity anchor has a huge volume, and the anchor block in the gravity anchor belongs to the mass concrete construction, and the concrete volume is large. The existing During the construction of the anchor block structure, if the amount of concrete is reduced, it cannot be used as ...
