Abutment refers to the substructure at the ends of a bridge span or dam whereon the structure's superstructure rests or contacts. Single-span bridges have abutments at each end which provide vertical and lateral support for the bridge, as well as acting as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support ends of spans unsupported by abutments. The design requirements for abutments are similar to those for retaining walls and for piers; each must be stable against overturning and sliding. Abutment foundations must also be designed to prevent differential settlement and excessive lateral movements.

The pier is the support of the bridge, located on the platform or foundation, used for supporting the main beam. The pier formwork is the most kind of bridge mould, which is usually composed of pier formwork and pier cap mould.The section size and appearance of the pier main depends on the girder type, the climate and the appearance. There are cylindrical, round end pier, conical pier, Y-shaped pier, double curved pier, vase pier, straight-line pier, v-shaped pier, rectangular pier and so on. Some piers have the connecting beam, such as double pier and Y-shaped pier.Pier formwork is generally divided into two types: pull rod form and non-stick form (including truss form).The pier cap is divided into the upper and lower circles, upper square lower circle, upper and lower square, upper circle and lower square.

Components: load-bearing structure, suspension system, anchoring device, running system, and working platform. The load-bearing structure is the main load-bearing component of the hanging basket. It bears all the weight of the construction equipment and the newly poured section concrete and transmits the load to the beams that have been constructed through the fulcrum and anchoring devices.

The walking system of the cradle can be track or tetrafluoroethylene skateboard, and the traction power is generally an electric winch, which includes a front traction device and a tail cable protection device. In order to ensure that the hanging basket has sufficient anti-overturning stability when pouring concrete, the rear anchoring is often set at the tail of the hanging basket, which is generally realized by the vertical prestressed tendons buried in the beam ribs. When the rear anchoring capacity is insufficient, it can also be used for tail weight and other measures.

Hydraulic tunnel lining formwork is mainly used in the construction of medium length tunnel, the construction progress and concrete surface quality are higher.

Hydraulic tunnel lining formwork is designed as the overall steel mould, the hydraulic oil cylinder out of the mould, whole construction supported by screw jack, electric speed reducer walks or cylinder automatic walking.

The anti-collision guardrail, as an essential facility of the expressway, has certain influence on high-speed driving safety, driving comfort, highway landscape, and project cost. Therefore, when constructing a highway, it is necessary to fully understand various anti-collision guards.

A pile cap is a thick concrete mat that rests on concrete or timber piles that have been driven into soft or unstable ground to provide a suitable stable foundation. It usually forms part of the deep foundation of a building, typically a multi-story building, structure or support base for heavy equipment, or of a bridge. The cast concrete pile cap distributes the load of the building into the piles. A similar structure to a pile cap is a "raft", which is a concrete foundation floor resting directly onto soft soil which may be liable to subsidence.

The T-beam and I-beam formwork is composed of side mould and end mould. The bottom mould is made of concrete. The side mould is composed of channel steel transverse rib, panel, I-steel support combination, section processing, side mould position fixed (end mould covers side mould) according to span and horizontal partition position. The end mould is made of steel rib and panel. The end mould, side mould and bottom mould are connected by a bolt.
