Embodiment 1

[0052] Such as figure 1 As shown, a method for preparing an integral cast-in-place arresting bed and its capture material includes the following steps:

[0053] A) Install anti-slip components: According to the design requirements, fix the plastic anti-slip anchors perpendicular to the road surface and consistent with the height of the arresting bed with epoxy resin at certain intervals in the set position of the arresting bed;

[0054] B). Enclosure construction: In accordance with the design requirements, use construction wooden template to build the arresting bed to pour the enclosure, and seal and strengthen the joints;

[0055] C) Preparation of slurry: mix 180 parts by weight of sulphoaluminate cement, 5 parts by weight of calcium stearate, 50 parts by weight of water, and 0.5 parts by weight of sodium citrate, put them into a mixer for stirring, and then add gas-containing water Based on foam, quickly stir uniformly and make it uniformly prepared into a light slurry with certa...

Embodiment 2

[0066] Such as figure 1 As shown, a method for preparing an integral cast-in-place arresting bed and its capture material includes the following steps:

[0067] A) Pre-embedded anti-slip parts: According to the design requirements, at a certain interval within the set position of the arresting bed, pre-embedding the plastic anti-slip net frame perpendicular to the road surface and consistent with the height of the arresting bed;

[0068] B). Enclosure construction: According to the design requirements, use the plastic template for construction to build the barrier bed to pour the enclosure, and use the internal butter joint to seal it;

[0069] C) Preparation of slurry: mix 100 parts by weight of overfire lime, 100 parts by weight of powdered slaked lime (also called slaked lime), 4 parts by weight of silicone resin polyether emulsion, 55 parts by weight of water and 0.5 parts by weight of sodium citrate , Into the mixer for stirring, and then add the gas-containing water-based foam,...

Embodiment 3

[0078] Such as figure 1 As shown, a method for preparing an integral cast-in-place arresting bed and its capture material includes the following steps:

[0079] A) Install anti-slip parts: According to the design requirements, fix the plastic anti-slip grid perpendicular to the road surface and the same height as the arresting bed with epoxy resin at a certain interval in the set position of the arresting bed;

[0080] B). Enclosure construction: According to the design requirements, use templates to build a non-leaking barrier bed for pouring enclosure;

[0081] C) Preparation of slurry: mix 180 parts by weight of sulphoaluminate cement, 4 parts by weight of calcium stearate, 58 parts by weight of water, and 1 part by weight of sodium polyphosphate, put them into a mixer for stirring, and then add gas-containing Water-based foam, quickly stir evenly and make it evenly prepared into a light slurry with certain fluidity;

[0082] D) Pouring: The lightweight slurry prepared in step C) i...

Abstract

The invention discloses a preparation method of an integral cast-in-site arresting bed and a capturing material of the arresting bed. The preparation method comprises steps as follows: an inorganic cementing material, a foam stabilizer, a retarder, water and the like are mixed to form slurry, water-base foam is uniformly mixed in the slurry, light slurry is formed, and the slurry is directly and continuously poured into a pre-supported surrounding body equipped with anti-sliding parts through transfer equipment; a light solid hydrous material with certain strength is generated through hardening and is naturally cured without water loss till the moisture content is smaller than 30%, the hardening degree of the slurry reaches the design use strength, and a brittle porous material with a continuous honeycomb structure is formed inside. The preparation process of the integral cast-in-site arresting bed is simple, and the cost is low; the prepared capturing material has the volume to weight ratio being 150 kg / m <3>-300 kg / m <3>, the maximum compression compactness being not smaller than 70% and the crushing strength ranging from 0.2 MPa to 0.45 MPa, and the requirement for capturing a line-crossing airplane can be well met.

Description

Technical field [0001] The invention relates to a special road pavement, in particular to a method for preparing an integral cast-in-place arresting bed and its capturing material. Background technique [0002] It is one of the most harmful problems in aviation accidents that the plane rushes out of the runway. In order to prevent the plane from rushing out of the runway safety zone during take-off and landing and causing serious consequences, and to ensure the safety and comfort of passengers, the crossing aircraft is usually captured. The capture method usually uses the aircraft parachute and hook lock system and the arrest bed system (EMAS). EMAS is mainly composed of an arresting bed laid outside the safety zone at the end of the runway, with an installation length of 80-160 meters and a thickness of tens of centimeters. When the stalled cross-border aircraft enters the arresting bed while rushing out of the runway, the brittle porous capture material is crushed under the cr...
