Description

Install level standard core structure on basement rock

Technical Field

The utility model relates to a water conservancy water and electricity safety monitoring field especially relates to an install level standard core structure on basement rock.

Background

Monitoring the settlement of building and side slope is more and more important in water and electricity engineering, in order to timely accurate gain monitoring data, need bury some level punctuations underground on being monitored the thing, judges the settlement condition of being monitored the thing through the detection to the level punctuation. Different level mark points need to be buried aiming at different topographic and geological conditions, when facing bedrock, the traditional installation method is to directly drill holes on the bedrock and bury a level mark core as a mark of a monitored object, but the level mark core is not easily protected by the method, and is easily lost after a long time, so that a novel level mark core structure mounted on the bedrock needs to be designed.

SUMMERY OF THE UTILITY MODEL

For overcoming the current not enough such as damage or loss of burying the water standard core on the basement rock underground, the utility model aims to solve the technical problem that: the utility model provides a can play the water standard core structure of installing on the basement rock of good guard action to the water standard core on the basement rock.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides an install water mark core structure on basement rock, is including setting up the observation mound on the basement rock, the top of observing the mound has buried the water mark core underground, the top of water mark core is equipped with mark core cover board and covers the water mark core cover on observing the mound.

Furthermore, the observation pier is of a reinforced concrete structure penetrating into the bedrock, and a rammed sandstone layer is arranged around the observation pier.

Furthermore, the observation pier is integrally of a frustum-shaped structure with a smaller upper end and a larger lower end.

Further, the observation pier penetrates into the bedrock and accounts for 40-45% of the height of the whole observation pier.

Further, a concrete base is arranged at the top of the gravel layer, the concrete base surrounds the top of the observation pier, and a concrete cover plate is arranged at the top of the concrete base.

Further, a handle is arranged at the top of the concrete cover plate.

The utility model has the advantages that: through set up an observation mound on the basement rock, set up level mark core and mark core apron on observing the mound, utilize and observe the mound and come firm level mark core, utilize mark core apron to come to cover the protection to level mark core, overall structure has characteristics such as simple and easy, durable reliable, pleasing to the eye practicality, can avoid level mark core to damage and lose to improve basement rock settlement monitoring's reliability.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Marked in the figure as 1-bedrock, 2-observation pier, 3-level mark core, 4-mark core cover plate, 5-gravel layer, 6-concrete base, 7-concrete cover plate and 8-handle.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, the utility model discloses an install water mark core structure on basement rock, including setting up observation mound 2 on basement rock 1, the top of observing mound 2 has buried water mark core 3 underground, the top of water mark core 3 is equipped with standard core apron 4 and covers the cover with water mark core 3 on observing mound 2. The traditional mounting mode is that directly drill hole on the basement rock, then lay the level mark core downthehole, because the rock mass steadiness is relatively poor to there is not the safeguard measure, the easy not hard up damage or the loss of level mark core laid. The utility model discloses a set up and observe mound 2 and mark core apron 4 back, can play fine fixed and guard action to level mark core 3, examine time measuring when needs, only need open mark core apron 4 can, convenient and fast.

When setting up and observing mound 2, clear away the overburden soil body on the basement rock 1 earlier, until seeing fresh rock mass, observe the bottom basis of mound 2 and go deep into basement rock 1, pour with 8 diameter 12 reinforced concrete, the upper portion is poured into reinforced concrete structure with 4 diameter 12 reinforcing bars as the support, fills and tamps with grit layer 5 afterwards all around, guarantees to contact well, improves the steadiness of observing mound 2.

Because it has the take the altitude to observe mound 2, for the stability of guaranteeing the structure, observe mound 2 global design for the upper end less, the great frustum shape structure of lower extreme, this structural shape is favorable to gravel layer 5 to the firm effect of observing mound 2 simultaneously. In order to further ensure the connection reliability of the observation pier 2 and the bedrock 1, the size of the observation pier 2 penetrating into the bedrock 1 accounts for 40-45% of the height of the whole observation pier 2.

Because rock rolling, wood falling and the like easily occur around the bedrock 1 and the leveling marker core 3 cannot be completely protected only by the marker core cover 4, a concrete base 6 can be arranged at the top of the gravel layer 5, the concrete base 6 surrounds the top of the observation pier 2, and a concrete cover plate 7 is arranged at the top of the concrete base 6. To ensure stability, the concrete base 6 and the concrete cover plate 7 are preferably cast by reinforced concrete, and the concrete base 6 can be inserted into the sandstone layer 5 to a certain depth. In order to facilitate the opening, a handle 8 can be arranged above the concrete cover plate 7.

The utility model discloses a set up an observation mound on the basement rock, set up level mark core and mark core apron on observing the mound, utilize and observe the mound and come firm level mark core, utilize mark core apron to come to cover the protection to level mark core, whole structure has characteristics such as simple and easy, durable reliable, pleasing to the eye practicality, can avoid level mark core to damage and lose to improve the reliability that the basement rock subsides the monitoring, fine practicality and application prospect have.
