Description
Technical field
The invention belongs to bridge traffic engineering technical field, be specifically related to a kind of anchorage system for stable trestle.
Background technology
Trestle is in civil engineering, the temporary bridge facility built for transport material, equipment, personnel, is divided into timber trestle bridge and steel trestle by the material adopted, and the bridge floor position of trestle is typically based on the structure structure size constructed and locus is determined.The trestle that bridge floor position is higher, exposes pile drift relatively big, and bridge floor passes through or operation is easily caused rocking or toppling of trestle, brings serious potential safety hazard to the safety of workmen.
Summary of the invention
It is an object of the invention to provide a kind of anchorage system for stable construction bridge, to ensure that bridge floor passes through and construction safety.
For achieving the above object, the technical solution adopted in the present invention is a kind of anchorage system for stable trestle, and this system includes anchorage 1, anchor chain 2, steel wire rope 3, trestle 4, and anchorage 1 includes anchorage main body 1.1, cutting shoe 1.2, cat ear 1.3, suspension ring 1.4.
Specifically, described anchorage 1 is inverted asymmetric U-shape structure, and its top is embedded with U-shaped suspension ring 1.4.One jiao, the bottom of anchorage 1 is anchorage main body 1.1, and anchorage main body 1.1 is obtuse angle, plays counterweight effect；Another angle, the bottom of anchorage 1 is cutting shoe 1.2, and cutting shoe 1.2 is acute angle, the surface of cutting shoe 1.2 by prefabricated, polish, inlay the modes such as high-abrasive material and make it sharp, in anchor chain 2 tensioning process, play acting on grabbing.Being embedded with cat ear 1.3 between cutting shoe 1.2 and the top of anchorage 1 of anchorage 1, cat ear 1.3 is connected with anchor chain 2.
Trestle 4 is symmetrically arranged on two with steel wire rope 3, and steel wire rope 3 is connected with trestle 4 by winding, ground tackle form, makes trestle 4 stress balance；Described steel wire rope 3 is connected with the cat ear 1.3 of anchorage 1 by anchor chain 2, and anchor chain 2 and cat ear 1.3, steel wire rope 3 are by snapping connection；Anchorage 1 fixes on the ground；Adjusting both sides anchor chain 2 by symmetry and make its tensioning, the purpose the final and trestle 4 that reach anchoring form rock-steady structure.
The material of described anchorage 1 is armored concrete or metal.
Compared with prior art, the present invention has the following advantages.
Present invention efficiently solves owing to pile own length in trestle bottom is relatively big, trestle is current or and shortcoming that cause trestle rock and topple excessive due to moment in operation process.Owing to being respectively provided with one or multi-channel anchorage system in trestle both sides, by the tensioning of anchor chain, anchorage system and trestle are collectively forming redundant structure, are finally reached the effect of stable trestle.Anchorage system can be applicable to the construction bridge under rivers or usual terms.

Detailed description of the invention
As shown in Figure 1-2, a kind of anchorage system for stable trestle, this system includes anchorage 1, anchor chain 2, steel wire rope 3, trestle 4, and anchorage 1 includes anchorage main body 1.1, cutting shoe 1.2, cat ear 1.3, suspension ring 1.4.
Specifically, described anchorage 1 is inverted asymmetric U-shape structure, and its top is embedded with U-shaped suspension ring 1.4.One jiao, the bottom of anchorage 1 is anchorage main body 1.1, and anchorage main body 1.1 is obtuse angle, plays counterweight effect；Another angle, the bottom of anchorage 1 is cutting shoe 1.2, and cutting shoe 1.2 is acute angle, the surface of cutting shoe 1.2 by prefabricated, polish, inlay the modes such as high-abrasive material and make it sharp, in anchor chain 2 tensioning process, play acting on grabbing.Being embedded with cat ear 1.3 between cutting shoe 1.2 and the top of anchorage 1 of anchorage 1, cat ear 1.3 is connected with anchor chain 2.
Trestle 4 is symmetrically arranged on two with steel wire rope 3, and steel wire rope 3 is connected with trestle 4 by winding, ground tackle form, makes trestle 4 stress balance；Described steel wire rope 3 is connected with the cat ear 1.3 of anchorage 1 by anchor chain 2, and anchor chain 2 and cat ear 1.3, steel wire rope 3 are by snapping connection；Anchorage 1 fixes on the ground；Adjusting both sides anchor chain 2 by symmetry and make its tensioning, the purpose the final and trestle 4 that reach anchoring form rock-steady structure.
The material of described anchorage 1 is armored concrete or metal.
Embodiment one
For the trestle at rivers place, prefabricated anchorage can be transported to appointment position by barge, crane barge, slowly transfers to, at the bottom of rivers, then connecting anchor chain, steel wire rope and trestle, reach anchoring effect.
Embodiment two
For the trestle in anhydrous location, directly specifying position to carry out prefabricated to anchorage, after treating that anchorage reaches design strength, being attached by anchor chain and steel wire rope and trestle, anchoring effect can be reached.
